Description from war.gov

This document is an administrative, programmatic, or contractor-produced record related to the Advanced Aerospace Weapon System Applications Program (AAWSAP), a Defense Intelligence Agency (DIA)-administered program active from 2008 to 2012. AAWSAP’s official scope of work identified 12 technical research areas relating to potential aerospace threats over a time horizon of more than 40 years. As part of the broader program record, the file documents how AAWSAP was scoped, organized, tasked, funded, executed, or described at a particular point in time. This November 2010 Bigelow Aerospace Advanced Space Studies (BAASS) contractor-authored capability statement presents BAASS’s analysis as technically rigorous and strategically valuable. The document appears intended not only to describe BAASS’s analytical capabilities but also to reinforce the case for the organization’s continued relevance and for the continuation of AAWSAP. The document summarizes the company’s self-assessment of the suitability of its personnel, software, equipment, field sensor, and data warehousing capabilities for analyzing unidentified aerial phenomena (UAP) and unidentified submerged objects (USOs). It includes excerpted case findings and uses selected case studies and modeling exercises as demonstrations of BAASS’s analytical capabilities. The report describes BAASS as combining field collection resources, historical databases, and computational tools such as ANSYS Multiphysics to model UAP incidents through engineering and physics analysis, including work on radar cross section, fluid behavior, acoustics, and aerodynamic performance. It also presents BAASS’s in-house capabilities as supporting both threat assessment and the study of advanced aerospace technologies, while asserting that analysis of UAP performance characteristics could inform future developments in propulsion, stealth, detection, and weapons systems.

1. EXECUTIVE SUMMARY The purpose of this report is to summarize the field data collection, in-house databases and computational capabilities that currently reside at Bigelow Aerospace Advanced Space Studies (BAASS) for the study of advanced aerospace technology. Between 2008 and 2010 BAASS was contracted by the Defense Warning Office of the Defense Intelligence Agency (DIA) to create, staff, and equip a new organization in order to examine and analyze the threat to national security associated with advanced aerospace technology. By selecting and modeling a few sentinel cases of encounters with advanced aerospace technology, this report demonstrates the in-house data collection, data storage and analysis resources built by BAASS under DIA contract HHM402-08-C-0072. Throughout the millennia individuals have observed and reported unexplained phenomena in the sky. Some of these reports included bright and flashing lights, objects streaking across the sky or silently hovering, and multiple colored and flashing structures morphing into one. Cylindrical, cigar, spherical, lenticular, triangular and ellipsoid shaped structures have been reported hovering and/or accelerating at rapid rates from a stationary position. Some of these abrupt, high speed maneuvers have been harder to explain with conventional physics, considering the inherently poor aerodynamic properties of many of these objects. It should be stressed many, but not all, of these sightings may be explained by natural phenomena, or by unacknowledged aerospace technology. Several official government studies were conducted from the late 1940s until around 1970, but many of these studies were superficial and lacking in rigor. Since 1970, because of an absence of research funding, the study of Unidentified Aerial Phenomena (UAP) has been characterized by cursory analysis and amateur, unscientific data collection. Pilots, both civilian and military, have reported seeing unusual objects in the air, some of which have been independently confirmed by radar. During the 1960s and 1970s a series of incidents was reported along the so called Northern Tier of the United States where silent hovering objects were observed over military facilities housing nuclear weapons. One report in March 1967 involving the simultaneous disabling of multiple missiles for a period of time, while a UAP allegedly hovered nearby, stimulated considerable public interest when information of the event began to emerge. The 1967 incident, if true, as well as other Northern Tier incidents, arguably had national security implications. Over the years, there have also been numerous reports of Unidentified Submerged Objects (USO), in all bodies of water. Some USO and UAP reportedly exhibited superior performance capabilities in velocity and acceleration underwater in the absence of detectable turbulence or cavitation signatures. While comparing our state of the art military equipment with these capabilities a reasonable individual may conclude there are national security implications. Bigelow Aerospace Advanced Space Studies, LLC (BAASS) is a research organization focused on the identification, evaluation, and acquisition of novel and emerging future technologies worldwide as they specifically relate to air and space craft. Cutting edge research areas include propulsion systems, space applications of nanosensors, piezoelectric and nanowire fabrics, human performance, plasma stealth technologies, and directed high energy weapons.

was contracted to the Defense Intelligence Agency (DIA) in 2008 to investigate and analyze the possibility of a credible threat posed by UAPs. To accomplish this mission, BAASS over the past two years has focused on developing three separate resources, each unique to the study of UAP: 1) to obtain the most comprehensive suite of portable field sensors and personnel available, 2) to build the most all-inclusive database of UAP performance capabilities and behavior in the world and 3) to acquire world class computational methodology for analysis of UAP data. This report touches on all aspects of these resources, but concentrates on the in-house computational capabilities. BAASS acquired the ANSYS Multiphysics Finite Element Analysis (FEA) program, for "a first of a kind" engineering and physics in-house resource devoted to providing a scientifically sound mathematical analysis and modeling of UAP behavior. Thus BAASS has acquired significant computational capability to convert field data into mathematical models and three dimensional simulations. This report provides theory, analytical and numerical solutions for selected UAP and USO incidents through engineering and physics analyses. In particular, we examine a sentinel incident - the "Tic Tac" event - where F/A-18 aircraft from a United States Carrier Strike Group were vectored to a nearby unidentified contact in November 2004. The white object observed by four F/A-18F aircrew was described as 40 feet in length and shaped and colored like a "Tic Tac" candy. Many analyses of UAP may use analytical or closed form solutions to solve the equations that describe the physics of an event. Where analytical solutions do not exist or the geometry is too complex, ANSYS multiphysics provides a powerful computational platform to solve large problems numerically, while combining and solving many different physical equations. Compressible fluid flow analyses were performed to visualize the steady state pressure, temperature and Mach number contours around two craft shapes. An incompressible fluid flow problem around a solid dise shaped object descending through the air into a body of liquid was investigated to observe the disturbance produced on the surface of the water. A successful analysis of a USO was conducted using a full harmonic acoustics simulation; and computed values showed good agreement with the expected theoretical solutions. An analysis of a spherical UAP radar cross section (RCS) was conducted using a full harmonic electromagnetic simulation. Various other shapes of UAP and USOs may be evaluated by applying boundary conditions and transient physics equations to obtain a better understanding of the capabilities of these objects. BAASS employees and contractors comprise scientists, engineers, analysts, intelligence and investigative professionals with a wide range of technical capabilities and backgrounds. Many of the professional staff members are considered national and international experts in their respective fields. BAASS' personnel have experience in performing work for government agencies such as the Department of Energy and Department of Defense. A broad mandate to research and develop future technology platforms pertaining to advanced propulsion, advanced non-aerodynamic lift capabilities, future material science breakthroughs including nanofabrication, novel power generation and signature reduction technologies, human interaction and effects of advanced technologies including field and radiation biological effects exists in Summary Report on BAASS UAP Analysis Capabilities Page 11 November 23, 2010

BAASS' work scope. BAASS' vision is to identify and acquire disruptive or discontinuous technologies that will form the basis of aerospace and defense applications through the year 2050, as well as those that pose potential threats to national security. The company goal is to become a major entity in the research and development of future classified and unclassified endeavors.

2. INTRODUCTION 2.1 HISTORICAL EVENTS AND STUDIES Disc, triangle, cigar and bell-shaped flying objects have been reported and documented on a global basis for millennia. The sighting by 1843(a)(2) Jon June 24, 1947 in the state of Washington garnered unprecedented global media attention and began the modern UFO era. While flying near Mt. Rainier, he observed a chain of nine unusual objects flying from north to reported that "two or three of them would dip or change course slightly, just enough for the sun to strike them at an angle that reflected brightly on my plane." The specific 1843(a)(2) term "flying saucer" was never used by however, he was quoted in a book stating: "As I described them at the time their flight was like speed boats on rough water or similar to the tail of a Chinese kite that I once saw blowing in the wind. As I put it to newsmen in Pendleton, Oregon, they flew like a saucer would if you skipped it across the water." 1843(a)(2) the moniker "lying saucer" was born. The terms "lying saucer" and "lyng ais" were used commonly and interchangeably in the media to describe what are now known as UFOs (Unidentified Flying Object). Many sightings of UFOs were reported by commercial and military pilots during the late 1940s and a flying saucer allegedly crashed outside of Roswell, New Mexico, in early July 1947. Shortly thereafter, a series of sightings of "green fireballs" began. These reports were almost exclusively over the state of New Mexico. Increasing significantly in number by December 1948, these sightings typically occurred over sensitive government installations, most notably the Los Alamos and Sandia National Laboratories. An investigation was initiated by meteor expert 1843(a)(2) horizon on a horizontal trajectory on December 12, 1948 After personally witnessing a green fireball four to five degrees above the concluded the fireballs were 1843(a)(2) structured, that is, not atmospheric phenomena. Initially they were thought to be of Russian origin. In April 1950, Project Twinkle was created to be a network of stations with the purpose of observing, studying, and collecting data on the fireball phenomena. This project did little to solve the mystery, and was disbanded later that year. Large numbers of UFO sightings continued in the late 1940s and as a result, some unease about the nature of the objects began to escalate in military circles, notably in the Air Force. For example, in September 1947, Air Force issued a memorandum stating "The reported operating characteristics such as extreme rates of climb, maneuverability (particularly in roll), and motion which must be considered evasive when sighted or contacted by friendly aircraft and radar, lend belief to the possibility some of the objects are controlled either manually, automatically or remotely." 1843(a)(2) recommended a detailed study of the UFO phenomenon. Based on increasing concern on the part of the military, the U.S. government initiated official studies of UFOs. Project Sign was the first official U.S. government study of UFOs performed by the United States Air Force in early 1948 and concluded in early 1949. Project Sign officials argued UFOs were likely of extraterrestrial origin, and most of the project's personnel came to favor the extraterrestrial hypothesis. This hypothesis was rejected by the senior Air Force personnel. Project Sign eventually came to no official conclusion about UFOs with the final report stating the existence of flying saucers could neither be confirmed nor denied. Project Sign was concluded and restarted as Project Grudge in February 1949. Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 13

Project Grudge attempted to give each and every case a solution or an identifier tag. Grudge existed in various form and name until project completion in March 1952. The final Project Grudge report stated 22% of cases were categorized as unidentified, 69% identified, and 9% contained insufficient information to categorize. In March 1952 Project Blue Book replaced Grudge and remained headquartered at the Air Technical Intelligence Center at Wright-Patterson Air Force Base in Ohio. Over the next seventeen years, Project Blue Book recorded approximately 15,000 UFO incidents, and Blue Book reported 701 of these incidents as "unidentified" la dramatic spike in UFO sishtines in 1952 prompted the CIA to convene a scientific panel, Jaanizations tha the ring cent UP daca. It is widely stated among modern day advocated a campaign to "debunk" UFOs. Beginning on November 1, 1966, the Air Force Office of Scientific Research awarded $313.000 to a research team at the University of Colorado 1843(a)(2) to study the scientific implications of UFOs. The study was undertaken on the material furnished by Project Blue Book. The 1843(a)(2) final (and controversial) conclusion stated "we have recommended against the mounting of a major effort for continuing UFO study for scientific reasons." 1843(a)(2) announced Blue Book would be closed due to the fact further funding "cannot be justified either on the grounds of national security or in the interest of science." The last publicly taken report for project Blue Book operations was December 17, 1969, but officially it closed on January 30, 1970. Since the end of Blue Book numerous organizations have taken on the role of UFO/UAP investigations. Few of these groups have been professionally organized, trained, or equipped to properly investigate the phenomena. In contrast, one purpose of this report is to show BAASS is on the route to being the leading force in complete investigation and scientific analysis of the phenomena. 2.2 BAASS' TWELVE TECHNOLOGY FOCUS AREAS BAASS is a research organization focused on the identification, evaluation, and acquisition of novel and emerging future technologies worldwide as they specifically relate to air and space craft.

2.3.3.6 Hardware for ANSYS Workbench Platform The research and work performed by BAASS ranges from technical design and prototyping, all the way up to advanced theoretical and computational studies of partial differential equations describing multiphysics problems. An expandable twelve core Hewlett Packard server with 48 GB of RAM and 1 TB of storage is used to perform parallel processing solutions for structural, fluid flow, heat transfer, high and low frequency electromagnetic problems along with coupled physics of two or more of those listed previously. 2.3.4 Data Warehouse BAASS developed a Data Warehouse to support research on UAP and related anomalies and titled it "Project CAPELLA". The BAASS Data Warehouse is revolutionary because it: 1) AAP Person incorporates a format based on the Six Layer Model for analyzing UAP, 2) Person 58 includes several new databases developed by BAASS, and 3) includes databases developed by others which have never been collectively analyzed. The Data Warehouse currently consists of eleven separate databases and their associated supporting documentation in electronic format such as witness interviews, photographs, videos, recordings, sketches, analytical reports, etc. Each of the databases contains UAP sighting events relating to the purpose of that particular database, although some of the reported cases do overlap. Four of the databases will continue to catalogue current and future sighting reports. Seven of the databases have been completed and fully integrated and populated with all pertinent information captured by the CAPELLA format. BAASS will continue to input historical data in the CAPELLA format and will expand the Data Warehouse with additional databases and unusual aerial phenomena information. The eleven databases currently included in the Data Warehouse are: 1. NIDS Database 2. 1843(a)(2) Pilot Database 3. Sign/Grudge/Blue Book Database 4. UFOCAT Database 5. MUFON Case Management System Database 6. Project Colares Database 7. Canadian Release Database 8. United Kingdom Release Database 9. BAASS Database 10. Utah Ranch Database 11. Post-Utah Ranch Effects Database Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 19

Page 21

The BAASS Data Warehouse is an electronic repository for historical, ongoing, and future UAP reporting and investigations. The Data Warehouse is designed to facilitate sophisticated analyses and data mining to improve our understanding of the extent, structure, and frequency of UAP, as well as their potential correlation to known physical, environmental, biological, or socio-political factors. 2.3.4.1 CAPELLA Format AAP Person 5, AAP The CAPELLA database format is based upon the "Six Layer Model for Anomalous Person 58 Phenomena" developed by AAP Person 5 Jand AAP Person 58 This six layer model encapsulates all of the potential characteristics of UAP events that can be studied. The six layers are: 1. The Physical Layer - those physical characteristics associated with a UAP event 2. The Anti-Physical Layer - the patterns that conflict with those predicted in modern physics 3. The Psychological Layer - the psychological impacts to the witnesses) and the social conditions that surround them 4. The Physiological Layer - the effects perceived by humans 5. The Psychic Layer - the effects commonly found in parapsychology literature 6. The Cultural Layer - the primary and secondary effects upon society. Additionally, the CAPELLA format captures administrative details associated with the UAP event, such as witness information, location, date, time, duration, etc. 2.3.4.2 Data Warehouse Upgrade BAASS is undergoing a database upgrade project to further enhance data security and integrity, and increase processing power for greater analytical capability. The CAPELLA framework and methodologies will be preserved in the upgraded system. This upgrade will increase efficiency and effectiveness, and will allow databases to be analyzed individually or collectively. 2.3.4.3 Statistical Analysis BAASS has completed a first-level, yet comprehensive statistical analyses for three of the and the Utah Ranch Database. identify potential times and improve the means of future detection methods.

The UFO Pattern: A Condensed Statement of Repeated Observations As an important component of these studies, BAASS understands a considerable number, possibly a majority, of UAP reports can be explained by simple misidentification of current advanced technology platforms. Some recent black triangle and even possibly some saucer and hat shaped UAP reports over the last several decades may have been explained by aircraft sightings of the Lockheed SR-71 Blackbird (Figure 2), Lockheed F-117 Nighthawk Stealth Fighter (Figure 3), Northrop Grumman B-2 Spirit Stealth Bomber (Figure 4) and Boeing Phantom Works Stealth X-45A Unmanned Arial Vehicles (UAV) (Figure 5).

shaped UAPs which appear to hover and/or accelerate at rapid rates from a stationary position have been harder to explain considering the inherently poor aerodynamic properties of these objects. It is this latter subset of UAP reports that BAASS has focused on. © Jim Hatch lustration / www.krubsey.com Figure 2. Lockheed Martin Skunk Works SR-71 Black Bird Figure 3.

4. ANALYTICAL AND NUMERICAL SOLUTIONS FOR UAP INVESTIGATIONS 4.1 "TIC TAC" INCIDENT The following summary is excerpted from the report of an investigation conducted by personnel assigned to DIA of an observation by elements of the Nimitz Carrier Strike Group of UAP off the coast of Mexico in November 2004. Note: The DIA personnel who wrote the report utilized the term Anomalous Aerial Vehicle (AAV) rather than the more common Unidentified Aerial Phenomenon (UAP) or Unidentified Flying Object (UFO). All three terms, AAV, UAP, and UFO are used at different times in this section and should be considered interchangeable. During the period of approximately 10-16 November 2004, the Nimitz Carrier Strike Group (CSG) was operating off the western coast of the United States in preparation for their deployment to the Arabian Sea. The USS Princeton on several occasions detected multiple Anomalous Aerial Vehicles (AAVs) operating in and around the vicinity of the CSG. The AAVs would descend "very rapidly" from approximately 60,000 feet down to approximately 50 feet in a matter of seconds. They would then hover or stay stationary on the radar for a short time and depart at high velocities and turn rates. On 14 November after again detecting the AAV, the USS Princeton took the opportunity of having a flight of two F/A-18Fs returning from a training mission to further investigate the AAV. The USS Princeton took over control of the F/A-18s from the E-2C Airborne Early Warning aircraft and vectored in the F/A-18s for intercept leading to visual contact approximately one mile away from the AAV, which was reported to be "an elongated egg or a 'Tic Tac' shape with a discernable midline horizontal axis." It was "solid white, smooth, with no edges. It was "uniformly colored with no nacelles, pylons, or wings." It was approximately 46 feet in length. The F/A-18Fs radar could not obtain a 'lock' on the AAV; however it could be tracked while stationary and at slower speeds with the Forward Looking Infrared (FLIR). The AAV did take evasive actions upon intercept by the F/A-18 demonstrating an advanced acceleration (g), aerodynamic, and propulsion capability. The AAV did not take any offensive action against the CSG; however, given its ability to operate unchallenged in close vicinity to the CSG it demonstrated the potential to conduct undetected reconnaissance leaving the CSG with a limited ability to detect, track, and/or engage the AAV. the AAVs would descend from a very high altitude into the scan volume of the AN/SPY-1 at a high velocity. The top of the scan volume would put the AAVs at higher than 60,000 feet. The AAVs would descend "very rapidly" from approximately 60,000 feet down to approximately 50 feet in a matter of seconds. They would then hover for a short time and depart at high velocities and at turn rates demonstrating an advanced acceleration added that based on his experience, which is 17 years as a Fire Control on Aegis cruisers, the AAV exhibited ballistic missile Characteristics in reference to its appearance, velocity, and indications on the radar. Since the radar was in the mode to handle Air Intercept of conventional aircraft it never obtained an accurate track of the AAVs and was quickly "dropped" by the radar meaning it was eliminated by the computer to reduce the amount of clutter on the radar, as any other false target is handled. If the radar were set up in a mode for Ballistic Missile tracking they likely would have had the capability to track the AAV. They were detected three separate times during the week operating off the western coast of the United States and Mexico. The Tactical Air Officer onboard the Princeton could not identify the radar contact Summary Report on BAASS UAP Analysis Capabilities Page 25 November 23, 2010

and given the high speed and altitude was perplexed. On 14 November 2004, after again detecting an AAV took the opportunity of two F/A-18s airborne in the vicinity to task them for airborne reconnaissance of the AAV.

Location of the AAV during the F/A18 Intercept AAP Person 9 was flying a single seat F/A-18C that launched from the USS Nimitz at approximately 1030L to conduct a Functional Check Flight of an aircraft that had recently completed significant maintenance. He noted the weather that day was blue skies, no clouds, and unlimited visibility. After 30 minutes into his flight he received a radio call from his air controller asking him to investigate an unidentified airborne contact. This was not a standard request. Additionally the controller asked if he had ordnance onboard, which was odd since no controller had ever asked that question during a Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 26

1843(a)(2) situation of identifying an unknown contact over U.S. or International territory. He responded that he had no ordnance onboard. The controller provided vectors to the vicinity of Figure 8. The object was reported to be at "slow speed and low altitude." While en route at approximately 250 knots indicated/400 knots groundspeed at medium altitude (15-25,000 feet), he gained radar contact of what he believed to be two F/A-18Fs that were approaching the AAV from the west at low altitude (500- 5,000 feet). There was no other traffic on the radar. The controller informed him to remain above 10,000 feet, as there was other fighter traffic at low altitude investigating the AAV. As he approached approximately 15nm from the AAV descending through approximately 15,000 feet, he could see a water disturbance in the ocean surface. He recalled that the sea state was low (calm). At approximately 5-10 nm away from the AAV, the controller told him to "skip it" and return to his operating area. Since he was close he elected to fly over the water disturbance to try and see what was causing it. The disturbance appeared to be 50 to 100 meters in diameter and close to round. It was the only area and type of whitewater activity that could be seen and reminded him of images of something rapidly submerging from the surface like a submarine or ship sinking. It also looked like a possible area of shoal water where the swell was breaking over a barely submerged reef or island. He overflew the disturbance and turned back to the northwest. As he was flying away he could see the disturbance clearing and could no longer identify the place where it occurred. He did not see any object or vessel associated with the disturbance either above the surface, on the surface, or below the surface. He also never made visual contact with the other fighter aircraft that were vectored to the location or the AAV. It is possible that the disturbance was being caused by an AAV but that the AAV was 'cloaked' or invisible to the human eye. AAP Person 9 recovered aboard the Nimitz at approximately 1200L. He related to the Carrier Intelligence Center (CVIC) and was asked by his Intelligence Officer, saw the "supersonic Tic Tac"? We questioned now 1843(a)(2) to determine it he had any further information but based on his position in CVIC at the time he was not involved in any further discussions concerning the AAV. 1843(a)(2) He and were in the lead aircraft of the first F/A-18F section airborne That day from VEA-4T, (1843(a)(2) The flight walked, started and launched with no issue. They completed their departure from the USS Nimitz and flew to the working area to conduct the training portion of the flight. After they completed their training the E-2C controller handed them off to the USS Princeton 1843(a)(2) where they received vectors via Bearing Range Altitude Aspect (BRAA) to an unknown contact flying into the working area from the - asked what ordnance they had on board. 1843(a)(2) told_ they had two captive training AIM-9Ms (CATM-9) and no other ordnance. The flight descended to between 20-24,000 feet and proceeded to the contact. [1843(a)(2) did not recall any indications via on-board sensor of the object. Their aircraft was not carrying a Forward Looking Infrared (FLIR) pod onboard. As 1843(a)(2) remembers it, the radar Attack Display was clean (no targets).

As he scanned the area he gained a visual on the object. It is important to note that when asked to describe the disturbance on the water he stated that it was localized underneath the object, did not appear as a trail or wake, and looked like frothy waves and foam almost as if the water was boiling. At this point detached 1843(a)(2) which held at approximately 20,000 feet, and 1843(a)(2) descended to between 12-16,000 feet. 1843(a)(2) attempted a "helmet lock that was unsuccessful. It is important to note that 1843(a)(2) was using the Joint Helmet Mounted Cuing System which will cue the aircraft sensors such as the radar to 'lock on' to what the pilot is looking at and it also has a recording capability. It may have been useful in this situation but typically because of the large amount of head movement it is not practical. 1843(a)(2) stated that the helmet's recording capability was rarely used therefore he did not think to use it that day. communicated what they were seeing with control and said that he had a 1843(a)(2) running dialogue on the interflight radio with (1843(a)(2) stated that the object was "holding like a Harrier." (Referring to the AV-8B jet aircraft, which is capable of hovering and Vertical/Short Takeoff and Landing (V/STOL) via thrust vectoring.) According to | 1843(a)(2) the object's shape was like an elongated egg or a 'Tic Tac' and had a discernable midline horizontal axis. However, the object was uniformly white across the entire body. It was approximately 46 feet in length. 1843(a)(2) described it as "solid white, smooth, with no edges. It was uniformly colored with no nacelles, pylons, or wings." When asked to describe the appearance, if it glowed or reflected sunlight he said, "neither, it looked like it had a white candy-coated shell, almost like a white board." His report differs from (1843(a)(2) in that he reported the object traveling level at approximately 500-1000 feet at approximately 500 knots. The object was pointed in a north/south orientation and was moving both north & south and east & west, while maintaining a consistent altitude. These displacements, according to 1843(a)(2) were minor. (1843(a)(2) stated he then began a descent with the intention to take a close aboard pass with the object in an attempt to visually identify it. They began the decent as they rolled in from about 10,000 ft and approximately 350 knots to take the object close aboard. 1843(a)(2) pulled nose on and then pulled trail (aft) of the object. As they were maneuvering, the object 1843(a)(2) appeared, according to 1843(a)(2) ]"to recognize us." He assessed this from the fact the object "pointed" (realigned its axis) in the direction of their aircraft. At this time, according to the disturbance on the water ceased. As they completed this maneuver, the object ascended quickly and pulled lift vector on and aft of them at a supersonic speed. (1843(a)(2) commanded the radar through the Short Range radar set and asked for a picture from 1843(a)(2) initially reported that the "picture was clean" (no contact) but then stated "you're not going to believe this, it's at your CAP" meaning that the AAV had flown to their training CAP and had climbed to approximately 24,000 feet. Tacated in the southern end of the training area stated that the flight attempted to locate both the object and the disturbance with no success. stated that nothing was seen on the surface or subsurface and that there were no indications of the previous disturbance.

1843(a)(2) Following the engagement, the flight rejoined and returned to the USS Nimitz. When asked how the jets functioned and if there was any indications of a system malfunction, he stated that, "the jets were brand new, less than 100 hrs on them They were working perfectly." | 1843(a)(2) when asked, said that all aircraft systems were functional. That there were no mission computer issues or avionics issues and that there was no radio or communication interference and that they had entry into the Link-16 network. When asked, 1843(a)(2) couldn't confirm any physiological or psychological feelings that were out of the ordinary. 1843(a)(2) was a member of VFA-41 and was the 1843(a)(2) flying with 1843(a)(2) They were a part of the second F/A-18F section airborne that day from VFA-41. Their flight launched following the 1843(a)(2) _flight. The crews spoke with each other in the paraloft, discussed the object and that the flights were scheduled for the same working area. (1843(a)(2) _flight told 1843(a)(2) flight what they saw and to try to see and record what they could. There were no clouds and there was a discernable horizon. The time was approximately 1500L. All on board systems were functioning normally. The radar was in a standard search mode (RWS/ 80NM/ 4bar/ intr) and the FLIR was in L+S slave (the FLIR would point in direction of an L+S track). There was no radio or communication interference and they had entry into the Link-16 network. Initial awareness of an object came via the radar. According to the radar display, the initial tracks were at approximately 30-40 nm to the south of the aircraft. 1843(a)(2) was controlling the radar and FLIR and attempted multiple times to transition 1 the radar to Single Target Track (STT) mode on the object. The radar could not take a lock, the -sweep would raster around the hit, build an initial aspect vector (which never stabilized) an hen would drop and continue normal RWS b-sweep. When asked. (1843(a)(2 there were no jamming cues (strobe, champagne bubbles, "any normal EA indications"). It "just appeared as if the radar couldn't hack it." The radar couldn't receive enough information to create a single target track file. The FLIR, in L+S slave, pointed in the direction of the initial rack flies as the radar attempted lock. The FLIR showed an object at 0 ATA and approximatel 5 deg elevation (Figure 9). According to 1843(a)(2 "the target was best guess co-altitude or a few thousand feet below," estimating the object to be between 15-20 thousand feet. The object, according to the FLIR, appeared stationary (Figure 10). There was no discernable 1843(a)(2) Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 29

1843(a)(2) was clear in that he couldn't confirm that it was the same object as described by (1843(a)(2) flight. He never had visual, only seeing the object via the FLIR. He reaffirmed that all systems were functional. Following completion of the training portion, the section returned to the ship for a normal approach, landing and shutdown. The crew met in CVIC and debriefed. 1843(a)(2) said that the CIVC section attempted to collect his tapes but he refused They proceeded to their ready room where they debriefed with 1843(a)(2) Copies of the tapes were made with a set being turned into the intelligence section. ady rewin uh sre and his flight. 1843(a)(2) was not asked to sign any non-disclosure agreement and he is uncertain how far up the chain the reporting went past his commanding officer. When asked 1843(a)(2) couldn't confirm any physiological or psychological feelings that were out of the ordinary. He only expressed a feeling of confusion during the event. According to former(1843(a)(2) 1843(a)(2) I now a civilian working for (1843(a)(2) who was a onboard the Louisville in November 2004 during the AAV activity there were no unidentified sonar contacts in the vicinity of the aerial sightings or anytime during the operations off the coast of California. The former 1843(a)(2) confirmed that there was no anomalous undersea activity during this period. There was a live fire exercise conducted by the USS Louisville during the period of and in the vicinity of the AAV sightings; however, the weapon in use did not match the flight profile or visible characteristics of the AAV. Additionally any live fire would have been coordinated throughout the CSG and all air traffic would have been well aware of the launch and operation of the weapon system. Aircraft would not have been vectored for the intercept of a US Weapon in flight. Based on the lack of detection of any unidentified sonar contacts it is highly unlikely that an AAV operated below the surface of the ocean; it is possible that the AAV demonstrated the ability to be cloaked or invisible to the human eye based on pilot reporting of the water disturbance with no visible craft. Based on the assessment of 1843(a)(2) if the AAV did operate underwater undetected it would represent a highly advanced capability given the advanced capability of our sensors. Key Assessments According to DIA Report • The Anomalous Aerial Vehicle (AAV) was no known aircraft or air vehicle currently in the inventory of the United States or any foreign nation. • The AAV exhibited advanced low observable characteristics at multiple radar bands rendering US radar based engagement capabilities ineffective. • The AAV exhibited advanced aerodynamic performance with no visible control surfaces and no visible means to generate lift. • The AAV exhibited advanced propulsion capability by demonstrating the ability to remain stationary with little to no variation in altitude transitioning to horizontal and/or vertical velocities far greater than any known aerial vehicle with little to no visible signature. • The AAV possibly demonstrated the ability to 'cloak' or become invisible to the human eye or human observation.

The AAV possibly demonstrated a highly advanced capability to operate undersea completely undetectable by our most advanced sensors. The so called "Tic Tac" incident has many physics and engineering aspects that may be studied with regards to understanding the performance capabilities and propulsion mechanisms of the craft. Since there was little hard data, most analyses of the incident had to be made using either parametric studies or assumptions based on eye witness testimony. 4.1.1 Analytical Solutions of Velocities and Accelerations Associated with "Tic Tac" Performance An initial starting point consisted of using basic physics formulas for the calculation of velocities and accelerations based on the distances the object traveled and the duration time t of the Since no exact duration was known, as the radar operator noted that it occurred in a matter of "seconds," a parametric range from 0.5 seconds to 10 seconds was studied (assuming instantaneous velocities and accelerations). dv a =- dt Flight is classified in six categories as shown in the table below. Table 1. Mach Regimes Regime Mach Number Subsonic Transonic Sonic Supersonic Hypersonic High-hypersonic < 1.0 0.8 - 1.2 1.0 1.0 - 5.0 5.0 - 10.0 10.0 - 25.0 Re-entry Speeds > 25.0 Due to the lack of data, only the instantaneous velocity of the craft v and the instantaneous acceleration a, were computable. For the velocity and deceleration witnessed, a negative sign is implied to represent the direction component of the vector. Assumptions: 1. Elevation of 60,000 ft to Sea Level - It was reported by radar observation the object descended from approximately 60,000 ft to sea level in a matter of seconds. 2. Matter of Seconds - A range of 0.5 seconds to 10 seconds was used for a parametric study. 4.1.2 Summary of Analytical Velocity and Acceleration Solutions Table 2 provides the computed values of instantaneous velocities and decelerations in ft/s and mph and ft/sec and g respectively for each chosen At. Figure 11 through Figure 14 show Summary Report on BAASS UAP Analysis Capabilities Page 32 November 23, 2010

Page 34

non-continuous plots for velocity and acceleration in each unit for a specific At event duration. As one may observe from the table and graphs, extremely small and small duration times specifically between 0.5 and 5 seconds provide high velocities and accelerations. Most of the values in the table represent extraordinary velocities and all fall between hypersonic and re-entry speed Mach regimes. Acceleration values also show a very high number of g. An examination of Table 2 at a At of 5.0 sec reveals the average velocity of the craft was 12,000 ft/sec (8,182 mph or Mach 10.7). A very high deceleration value is also witnessed at 2400 ft/sec or 75 g. These are extraordinarily high values and would require some form of acceleration manipulation to limit what a human pilot would experience and be able to survive.

4.1.3 Numerical Analysis of Compressible Flow Compressible fluid flow analyses were performed to visualize the steady state pressure, temperature and Mach number contours around two craft shapes ("Tic Tac" and right circular cylinder).

Attachment Il and Attachment III show contours for subsonic speeds below 700 mph and supersonic increments between 700 mph and 1500 mph for the "Tic Tac" and a right circular cylinder respectively. A comparison of the profiles of the "Tic Tac" geometry and that of a right circular cylinder was performed due to other numerous reports of craft with similar capabilities but lacking curvature at the ends of the craft. A flat 90° surface moving through the air would be expected to cause greater resistance during flight. Assumptions: 1. Elevation of 30,000 ft - It was reported by radar observation the object descended from approximately 60,000 fi to sea level in a matter of seconds. An average As is computed by: As = 52 - 51 60,000ft - Oft - = - = 30,000ft 2. Ambient Air Temperature of 223 K (-58F) - An approximate ambient environmental temperature of 223 K was chosen in accordance with an average elevation in the range of 30,000 ft (which varies with weather conditions) as a starting point for computational investigations. 3. Air Modeled as an Ideal Gas - Air Temperature, pressure and density are all interdependent and are given by the relationship of the ideal gas law: P- PRIT M where: Ru - Gas Constant (8.314472 m'-Pa-K'•mol) M - Molar Mass (g/mol) T - Temperature (K) Since the temperature and density of air decreases with altitude, so does the speed of sound, ence a given true velocity results in a higher Mach number at higher altitudes. The slice us or the contours was taken axially for each geometric configuration. Reports from aircrew c sight indicate the object flew in a horizontal position. A 0° angle of attack was used in all cases to try to replicate observed flight conditions. Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 40

Cylinder Mach Number at 1/6 Scale, Air Temperature 223K and 1500 mph with Supersonic Inlet and Supersonic Outlet 4.1.4 Summary and Conclusions of Compressible Numerical Analyses In the field of UAP studies, it is believed this preliminary analysis of the "Tic Tac" incident is the first of its kind to utilize a multi-industry standard FEA code to perform computational studies. The cases used are provided as a basic demonstration of the CFX fluid flow module and illustrate some of its capabilities, as well as a sample of some visualization tools. 4.1.4.1 "Tic Tac" Geometry For the contour plots of pressure, temperature from 100 mph up to 500 mph, gradual increases in values are observed, with the most significant value change at the front of the object. The Mach number values increase at the front sides of the object. Disturbance of air flow is witnessed in the pressure and Mach contour profiles around the body. Nearing the speed of sound at 700 mph, contours for pressure and Mach number started to show a more pronounced shock as would be expected. Temperature values also showed a higher increase at the front nose due to higher flow and air resistance over the body. Velocities higher than 700 mph showed a drastic difference in values compared to those at 100 mph with pressure differences in orders of magnitude. At 1,100 mph, the temperature rises not only at the attack nose, but started to even increase on the sides and in the wakes of air flow. Detached shock waves were witnessed in the pressure and Mach contours starting at 700 mph all the way up to 1,500 mph. Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 46

Page 48

4.1.4.2 Circular Cylinder Geometry It would seem counter intuitive to have a craft with a flat face pushing through the air due to a major increase in air resistance. However, there have been many reports of objects of just the sort seen maneuvering in the skies. A comparison of the detrimental aerodynamic effects was sought in relation to the smoother edged body. At lower speeds, no large differences in values of pressures, temperatures or Mach numbers were observed. There were, however, slight differences in the location and profiles of the values of the "Tic Tac" geometry compared to the cylinder. None of these differences would indicate a drastic difference in conventional lift performance between the two geometries. The same appeared to hold true for higher speed scenarios, indicating no significantly different aerodynamic lift advantages between the two geometries. 4.1.4.3 Outcome Success was achieved in implementing the ANSYS Multiphysics and SolidWorks Solid modeling program to create and run input cases for compressible fluid flow over both the "Tic Tac" geometry and that of a right circular cylinder to illustrate pressure, temperature and Mach contour profiles over both shapes. Separated shockwaves were witnessed in higher velocity cases indicating that the possibility of a sonic boom or vibration may have been perturbated into the environment. The actual propagation distance of these was not of interest in this study and may be looked at in the future. It is doubtful the aircrew would have felt a shock wave in the cockpit unless extremely close to the object while traveling at high rates of speed, which the fighter jets were not. These basic geometries and assumptions helped provide an excellent starting point to create more complex transient cases that possibly incorporate heat generation, electromagnetic effects, and acoustics. This is demonstrated in a basic model that FEA algorithms describing multiphysics can provide to be an invaluable tool in gaining insight into UAP flight characteristics and even possibly rule out improbable scenarios. 4.1.5 Numerical Analysis of Incompressible Flow of a UAP Entering Water The problem studied was that of a solid disc shaped object descending through the air into a body of liquid. The model created, details the descent of a solid disc shaped UAP into water. It is assumed normal ambient conditions with a solid steel disc moving at a speed of 5 m/s in the negative y (downward) direction. The water surface is approximately 10 feet below the bottom of the UAP. Water and air temperatures are held at constant at 25°C and the gravitational acceleration constant at 9.81 m/s* . Ambient pressure was a constant 1 atm, buoyancy effects within the water were accounted for and the UAP was taken to be isothermal (no heat transfer between the system and the surroundings). Three distinct phases were created; a gaseous phase (air), the solid phase (UAP) and the liquid phase (water). Figure 26 displays the three dimensional geometry depicting the distinct regions and boundaries. The geometry was completed, and the necessary mesh was created in order to carry out the FEA analysis. Meshing is the discretization of a continuous domain into a set of discrete sub-domains called elements and is shown Figure 27. The governing equations were then solved for all Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 47

Page 49

elements within the domain. The accuracy of the solution increases with increasing number of elements (refining of the mesh). Typically, meshes are refined near domain borders or other places of interest; specifically where the solution is desired (for example the edge of solid object where it is desired to determine the amount of heat loss from the object). The solid UAP body was more refined than the air and water domains because it was of primary importance to study fluid flow around the UAP and not the flow of air/water further away from the solid domain. A close-up view of the refined mesh in the solid UAP domain is seen in Figure 28. Once the mesh was generated, then boundary and initial conditions were assigned to replicate approximate physical conditions during the event. As the name implies, boundary conditions are exact solutions to differential equations that exist on the outskirts of the different geometries. These conditions must be met if the solution is to be correctly determined. Initial conditions are time dependent relationships that describe the initial state of the problem. Thermophysical data must be defined for each domain. The governing equations include the properties of the materials involved (Cp, H, etc.) and an accurate analysis depends as much on the proper accounting of these properties as on the proper identification of boundary conditions. Boundary conditions on the solid UAP edges were set as a no slip surface. A no slip boundary sets the fluid velocity at 0. That is to say that a fluid coming in contact with the surface will not move (not slip). This is a typical boundary condition used when a fluid comes in contact with a solid body. In addition, the outside walls of the boundary were set as no slip. It was assumed that the walls were located far enough away from the UAP-water impact zone to play no part in determination of fluid movement around the solid UAP body. Thermophysical data was determined by material identification within the problem setup. The UAP was defined as being made of steel, the liquid body was set as water and the gaseous body was set to air. The initial velocity for the UAP was 0 m/s, that is to say the UAP initially starts at rest. Total simulation time was set to 10 seconds with 0.2 seconds per time step (for a total of 50 time steps). 4.1.6 Numerical Analysis of Incompressible Flow of a UAP Entering Water Results Upon completion of the simulation; an output file was created and stored for use in the post processing portion of Workbench called CFX-Post. Once the output file has been imported to CFX-Post; a variety of results may be obtained. For this investigation, a fluid dynamic analysis was performed. To best view the results; a plane (parallel to the y axis) was created to bisect the geometry (see Figure 29). The creation of a plane contained within the geometry allows for easy analysis of the solution. CFX-Post was used to determine the velocities of the air and water fluid domain, the pressure of the system and through examination of the volume fraction of water; a recreation of the ppearance of a solid entering the water. An animated representation of the transient results wa reated in an effort to understand how the trends in the specified variable change over time Figure 30 displays a still image of an animated result showing how the volume fraction of water changed as the UAP descended into the water domain.

Manipulation of the created plane view allowed for a two dimensional analysis for a variety of parameters. Figure 31 displays a still frame of the animation depicting how pressure varied throughout geometry. Figure 31 displayed the expected trend of an increasing pressure with increasing depth. A re-creation of the physical appearance of the UAP impacting and descending into water may be achieved through analysis of the transient animated results of volume fraction of water. Figure 32 displays a still shot of this animation after the UAP has impacted and entered the water domain. The radially expanding concentric circles display the resulting ripple effect after the solid has penetrated through the surface of the water. Figure 33 displays a side view of the same result. The original result animations from which the still screenshots (Figure 29 through Figure 33) were taken are provided in mpeg form. In addition to the preceding results, several animations depicting transient trends of fluid density and fluid velocity have been provided.

4.1.7 Summary and Conclusions of Numerical Analysis of Incompressible Flow of a UAP Entering Water Results The CFX-Post generated graphs and animations are illustrative samples of what ANSYS CFX is capable of producing. The scenario was chosen due to its simple geometry, boundary conditions and relative ease of computational requirements. A typical problem of this type when solved by hand, would have taken weeks if not longer. This simulation incorporated a fluid dynamic analysis and further analysis may incorporate numerous other multiphysics attributes in the study of UAP. Heat transfer from a craft entering the earth's atmosphere as well as the effects of varying craft size, shape and speed on wave generation during water impact could be studied just as easily. In addition to determining power requirements, achieved surface temperatures etc., re- creations of eyewitness sightings may be. Furthermore, electromagnetic capabilities allow for modeling of possible magnetohydrodynamic (MHD) affects. Electrodynamics can show the energy required to create magnetic fields with different materials as well as the propagation of electromagnetic waves through solid and liquid mediums. Using careful design and properties of human tissue in the program it would be possible to show effects on the human body from heat and high electric fields. Effects, such as increase in body temperature or nervous system interruption may be able to be quantified in ANSYS. This tool can greatly assist in the goal of studying human effects to reverse engineer UAP technology. 4.2 ANALYSES OF SPHERICAL UAPS 4.2.1 Acoustical Analysis of a Spherical USO Over the years, there have also been numerous reports USOs. In 1967, a UFO was reported crashing into Shag Harbour, Nova Scotia. It was reported that hovering and flashing orange lights were present, then it tilted at about a 45 degree angle and entered the water. A yellow light was seen in the water moving and leaving a trail of yellow foam. The Canadian Coast Guard was dispatched but by the time they arrived along with other vessels at the point of entry the yellow foam was all that remained. This is one of very few cases where governmental agency documents have formally declared an unidentified flying object was involved. At least eleven people saw a low-flying lit object head down towards the harbor. Multiple witnesses reported hearing a whistling sound "like a bomb," then a "whoosh," and finally a loud bang. Some reported a flash of light as the object entered the water. Several interviewed military witnesses, including a diver involved in an attempted recovery, have claimed an alien spacecraft was responsible. It was also claimed by several of the witnesses that the U.S. military was involved in recovery attempts. The case was also briefly investigated by the 1843(a)(2) UFO study, which offered no explanation. It has been proposed that this type of craft may operate using some sort of electromagnetic frequency based propulsion system to control underwater "flight" and to achieve incredible performance capabilities in velocity and acceleration.

Properties of Water Used for ANSYS Harmonic Analyses Property Water Density Speed of Sound Reference Pressure Value 1,000 kg/m° 1,500 m/s 1 × 10* Pa Figure 34 and Figure 35 show the FEA mesh for 25 elements per wavelength and 50 elements per wavelength for a 1,000 Hz analysis. Upon inspection of the maximum pressures shown in Figure 36 and Figure 37, it is apparent the FEA model solution was mesh independent with a pressure of 1,052 Pa for the 25 element per wavelength model and 1,103 Pa for the 50 element per wavelength model. Generally higher element models for meshes are considered more accurate, but a cost in computational time may be seen in extremely large models. In the runs performed, the 25 element per wavelength model showed sufficient accuracy and reasonable computation times. As frequency was adjusted higher, the elements per wavelength were adjusted down to limit element numbers. Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 60

4.2.1.1 Summary and Conclusions of Acoustic Analyses A successful analysis of a USO was conducted using a full harmonic acoustics simulation. The plots of the real and imaginary values showed good agreement with the expected theoretical solutions. It may be concluded from the contour plots and graphs that the varying frequencies produce acoustics pressures far out from the actual source and decline in an inverse square law relationship. In the future, ships and submarines could possibly detect these pressure disturbances and a frequency of the mode of operation could be calculated with a known distance from the vessel. 4.2.2 ANSYS Multiphysics Electromagnetic Capabilities The electromagnetic capabilities of ANSYS Multiphysics include a full-wave electromagnetic solver applicable to resonant, propagating, radiation and scattering phenomena in the frequency domain. RF or microwave passive components, antennas, attenuators, interconnects and related high frequency structures may be modeled for use in applications of stealth, electronic warfare and directed high energy applications. Post-processing calculations provide electric and magnetic field intensity, quality factor, scattering matrix parameters, voltage, current, characteristic impedance, radar cross section, far and near electromagnetic fields beyond the nodeled domain, antenna patterns, including period structures, and Joule losses (ANSYS, Inc. 2009). Magnetohydrodynamics may also be modeled in development of propulsion units anc power generation, electron beam dynamics and electrical discharges. The Maxwell Equations below provide the basis for electromagnetic calculations.

4.2.3 Radar Cross Section Analysis of a Spherical UFO Many UAP have been reported across the globe. Pilots have reported seeing these craft in the air, but when asked for confirmation of other aireraft in the area, air traffic control reports nothing on radar. Only a tiny fraction of energy is bounced back to the receiving antenna, even though many megawatts of power may be transmitted in a single pulse. The amount of power returned from a target to the transmitting radar depends on four major factors: 1. The power transmitted in the direction of the target. 2. The amount of power that impacts the target and is reflected back in the direction of the antenna. This is directly relational to the range between the antenna and target and the target's RCS. 3. The amount of reflected power that is received by the antenna. 4. The length of time in which the antenna is pointed at the target. Power of Waves Radiated Toward Target Fraction of Backscatter Captured by Antenna 9 10 ms Fraction of Intercepted Power Scattered Toward Radar Time on Target Figure 55. Factors that Determine the Energy Returned by a Target (Aerospaceweb.org, 2010) Power flux is used to describe the relationship between these variables. The further the radar wave travels, the greater the power transmitted decrease because it is spread over a larger area. The inverse square law of the range R or 1/R' governs the area over which the power is spread from the transmitting radar. The power flux or power density of the transmitted radar wave at the range of the target has a special name called the incident power density (Pincident). Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 83

Page 85

Power Density decreases by 1/R? A oc R2 - R Power reflected back to the radar depends on the power intercepted by the target and the target orientation Reflected power also spreads equally as it returns to the radar Figure 56. Effect of Distance from the radar to the Target on the Power Density (Aerospaceweb.org, 2010) When the radar wave reaches the target, a portion is reflected back to the antenna. In addition, the reflected power also dissipates at 1/R? therefore it is reduced by a factor of 1/R* roundtrip by the time it is returned to the antenna. The ability of a radar system to detect a target depends on whether the amount of power returned is great enough to be differentiated from internal noise, ground clutter, background radiation, and other sources of interference. This is defined as the signal to noise ratio. The object of stealth is to absorb or reflect waves away from receiving antenna and/or jam or propagate a false wave back to its source so that the target is nearly impossible to detect or track. Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 84

Page 86

The amount of power that is reflected back to the radar depends largely on a quantity called the radar cross section (RCS). RCS (o) is technically an area and typically expressed in square meters (m') and depends on the following three factors: Geometric cross section: The area of the object presented to the antenna or projected area is known as the geometric cross the target (Pintercepted) according to the following equation: Pintercepted = APincident Reflectivity: The reflectivity is the fraction of the intercepted power that is reflected by the target, regardless of direction. An object doesn't always reflect equally from all directions as some parts are flat or curved producing varying radar reflection and some of the power is absorbed by the object. Objects that have radar Absorbent Materials (RAM) and radar Absorbent Structures (RAS) are the target (scatter) to the power intercepted by the target (Pintercepted). Pscatter Reflectivity = APintercepted Directivity: The directivity is related to reflectivity but refers to the power scattered back in the direction of the receiving antenna. The power that is reflected toward the antenna is called the backscattered power (backscatter). Directivity is the ratio of the power that is backscattered in the direction of the antenna to the power that would have been scattered in that direction if the scattering were in fact uniform in all directions. Isotropic power (Pistropic) is the power scattered in a perfect sphere over a unit solid angle of that sphere. Pbackscatter Directivity = - Pisotropic Pbackscatter 47 scatter The reflected power will be much greater or much smaller than the isotropic power depending on how the target is oriented to the transmitting antenna. The directivity, therefore, will be much greater than 1 when the target returns a strong backscatter in the direction of the receiving antenna and much less than 1 when the backscatter is small. These three factors can be combined to determine the complete RCS (o) for a target. Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 85

RCS in square meters can be converted to dBsm by the following equation. dBsm = 10Log(RCSm2) It can be difficult to directly compare RCS estimates from one object to another since the RCS varies wildly depending on aspect, radar frequency and wavelength, and the fidelity of the receiver. Figure 59 illustrates typical RCS values for aircraft and other objects, ranging from insects and birds up to large ground vehicles and ships. The RCS of a stealth aircraft is typically multiple orders of magnitude lower than a conventional plane and is often comparable to that of a small bird or large insect.

Radar Cross Section Comparison (Aerospaceweb.org, 2010) A one-half symmetry analysis of the radar cross section of a UAP sphere with a dielectric coating was performed. Assuming the bottom limit of an ultrahigh frequency (UHF) very long range radar system is 300 MHz, a full scale RCS full harmonic analysis was performed to study a spherical object of 10 m in air with a 1 m dielectric coating layer.

4.2.3.1 Summary and Conclusions of RCS Analysis A successful analysis of a spherical UAP RCS was conducted using a full harmonic electromagnetic simulation. Upon inspection of the values of normalized RCS at 90°, the dB shown in Table 4 and Table 5, it is apparent the FEA model solution was mesh independent with a pressure of -0.64801E+01 dB for the 25 element per wavelength model and -0.66390E+01 dB for the 50 element per wavelength model. In the runs performed, the 25 element per wavelength model showed sufficient accuracy and reasonable computation times. The normalized RCS plots and electric field contour illustrate the variation of RCS dB and V/m values over a range of 0 to 180°. As one would expect, the values are largest at the point of incident of the radar wave and some reflection and also decrease in magnitude were witnessed around the sphere. Various shapes of UAPs may be evaluated for RCS and the resulting electric field due to an incidental radar wave is also attainable. This information may be used in the future for cases reported to determine the prominence of an object's expected RCS and whether similar radar returns were received.

5. SUMMARY AND CONCLUSION Compressible and incompressible fluid flow, dynamics, acoustics and radar theory all were provided in this report to give the reader a brief overview and understanding of the numerous physical equations that may be applied to reported UAP and USO behavior. Numerical solutions to these partial differential equation systems (many of which do not posses analytical or closed form solutions) which describe the physics of the event are achieved with millions of elements to model the object domain and medium. Each element may have numerous sets of coupled physical equations that need be solved by passing through many different computational iterations until convergence is achieved. BAASS is one of the few companies possessing the expertise, computer software and computational platforms to achieve such sophistication in numerical studies of UAP. Compressible fluid flow analyses were performed to calculate and visualize the steady state pressure, temperature and Mach number contours around two non-conventional craft shapes. A solid disc shaped object descending through the air into a body of liquid was investigated to provide visual simulation of the disturbance produced on the surface of the water through use of incompressible fluid flow. The USO analyses were performed using a full harmonic acoustics simulation and a spherical UAP RCS model was completed using a full harmonic electromagnetic simulation. For the individual summary and conclusions of each analytical and numerical study, see Sections 4.1.2, 4.1.4, 4.1.7, 4.2.1.1, and 4.2.3.1 of this report. From a more general perspective, BAASS was created in 2008 in order to facilitate the long term research and development of novel and emerging future technologies worldwide as they specifically relate to air and spacecraft. A large component of the BAASS mission is to study in depth the performance characteristics of UAP and USOs. From the data accrued, it is also BAASS's mission to produce a Threat Assessment of UAP and USO performance and capabilities. As a first step in accomplishing this mission BAASS has 1) acquired significant field data collection capabilities, both human and instrumented, 2) built the largest known UAP performance and behavior Data Warehouse in the world and 3) acquired advanced computational ability to analyze the data accrued. Research and development necessary for the procurement of the technology required for advanced space and weapons systems are conducted through use of computational Multiphysics FEA, development of computer code, experimentation, material science testing and manufacturing of prototypes in both BAASS in-house and collaborating facilities and laboratories. Academic areas of concentration include Computational Fluid Dynamics (CFD), Heat Transfer, Nuclear Engineering, Electromagnetics and Radio Frequencies (RF), Theoretical and Computational Physics, Biological Sciences and Chemistry. Theoretical and computational applications, as well as experimentation on components of non-conventional propulsion systems is under way to provide for future development of vehicles that are capable of operating in the atmosphere, under water and in space. Operation of the vehicle in different mediums, as well as a goal of hypersonic flight would provide superior performance in its ability to reach intended targets, faster delivery of weapons, greater effective Summary Report on BAASS UAP Analysis Capabilities November 23, 2010 Page 98

range and an engagement capability enabling employment of complex tactics against multiple targets across multiple domains. This research intends to provide innovative approaches and concepts for aircraft, propulsion, and flight technologies that demonstrate significant advances in performance and capabilities beyond those in operation today. This report outlined software, equipment and database descriptions along with select theory, analytical and numerical solutions for UAP incidents through engineering and physics analyses. Many analyses of UAP may use analytical or closed form solutions to solve the equations that describe the physics of an event. Where analytical solutions do not exist or the geometry is too complex, BAASS incorporates ANSYS Multiphysics to provide a powerful computational platform to solve large problems numerically, while combining and solving many different physical equations. The combination of computational software with field measurement equipment and historical databases of UAP events allows BAASS to utilize state of the art engineering techniques and tools to assess the operational capabilities of UAP and USOs. A greater understanding of these objects will allow for an accurate threat assessment, as well as provide the physics behind the incredible performance attributes that some have displayed. BAASS' acquired knowledge and capabilities are leading the way to quantum leaps in technology for travel in the atmosphere, space and under water, along with advances in armament and defense systems.

DOW-UAP-D175 is a November 23, 2010 summary report written by Bigelow Aerospace Advanced Space Studies (BAASS), a Defense Intelligence Agency contractor under the Advanced Aerospace Weapon System Applications Program (AAWSAP), contract HHM402-08-C-0072. The report runs to roughly 140 pages with extensive figures and attachments. It describes BAASS's personnel, field sensors, UAP data warehouse, and in-house ANSYS Multiphysics finite element software. Demonstration analyses include the November 2004 "Tic Tac" encounter, with velocity and acceleration estimates and compressible-flow models of two craft shapes. They also include a disc entering water, acoustic modeling of a spherical unidentified submerged object (USO), and a radar cross section model of a 10 m coated metallic sphere. It also gives a brief history of UFO studies from 1947 through Project Blue Book.

The document is a contractor self-assessment that also argues for continuing AAWSAP, so its claims are advocacy, not independent evaluation. The case studies are modeling exercises built on assumed geometries and reported parameters, not validated findings. The OCR shows redactions under exemption 1843(a)(2) in the historical section, which obscure the names of individuals. The text provided is truncated before the technical analyses.
