AAWSAP: The Pentagon's Bigelow Contract and Its 38 Papers

In the summer of 2008 the Defense Intelligence Agency wrote down what it wanted. It was not a UFO study. The Statement of Objectives, dated 18 July 2008, describes a contractor-supported effort to assess far-term foreign aerospace threats by understanding the physics and engineering of possible breakthrough technologies out to the year 2050, rather than by extrapolating from the aircraft and missiles of the day. It listed twelve technical areas: lift, propulsion, control, power generation, spatial or temporal translation, materials, configuration and structure, signature reduction, human interface, human effects, armament, and supporting topics. It asked for monthly status reports, a management plan for each technical area within 60 days, research reports and briefings by the tenth month, and a final integrated threat assessment.

The program was called the Advanced Aerospace Weapon System Applications Program, or AAWSAP. On 18 September 2026 the Department of War published its paperwork in the sixth tranche of the PURSUE disclosure program: the Statement of Objectives, the original contract, five contract modifications, and 37 Defense Intelligence Reference Documents written between December 2009 and January 2011. Each has its own page on this site. Taken as a set, they show a threat-forecasting contract that produced a shelf of physics literature reviews while, according to the government’s own later history, the contractor spent part of its effort on UFOs and paranormal claims.

The contract

The solicitation and original order, dated 22 September 2008, went to Bigelow Aerospace Advanced Space Studies, Inc., or BAASS, an arm of the Las Vegas aerospace company founded by the hotel magnate Robert Bigelow. The order folded BAASS’s proposal in by reference and turned the Statement of Objectives into priced line items: monthly reports, management plans for the twelve areas, research reports, a comprehensive integrated threat assessment, travel and other direct costs, with option-year items for follow-on work. The contract number, HHM402-08-C-0072, runs through every later modification.

The modifications trace a contract that was kept going but was never comfortable. Modification P00001, signed on 2 September 2009, extended the base period to 30 September 2009, set the first option year to run from October 2009 to September 2010, and exercised that option subject to the availability of appropriated funds. P00002 followed in February 2010. It funded the option year and removed that condition, but it also recorded that Option Year 1 was receiving reduced funding and set out the impact on deliverables. On 18 May 2010, P00003 changed the Contracting Officer’s Representative, the government official who oversees the contractor day to day, and P00004 brought the internal records in line with that change. The last one released, P00005 of 28 September 2010, extended the period of performance to 21 December 2010 with no additional funding and no other changes.

The documents stop there. AARO says the program ended in 2012, and nothing in this release covers the gap.

Where the money came from

The public history is better documented than the contract file. AARO’s Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena, Volume I, dated February 2024 and published in March, says that at the direction of Senate Majority Leader Harry Reid, the Defense Appropriations Acts for fiscal years 2008 and 2010 appropriated $22 million for the DIA to assess long-term foreign advanced aerospace threats. Reid was Robert Bigelow’s senator. Press accounts since 2017 have described the two men as longtime acquaintances, and have said that Senators Ted Stevens and Daniel Inouye supported the appropriation. AARO also records that on 24 June 2009 Reid wrote to Deputy Secretary of Defense William Lynn III asking that the program be made a Special Access Program, the most tightly restricted category of classified effort. Lynn declined, on the advice of James Clapper, then Under Secretary of Defense for Intelligence, who judged the designation unjustified.

One small discrepancy is worth noting. AARO says the DIA “established AAWSAP in 2009.” The contract released in 2026 is dated September 2008.

What a DIRD is

The thirty-seven papers are the part of AAWSAP that people have argued about most, and the government’s cover note on each one is blunt. A Defense Intelligence Reference Document, it says, is “a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use,” and DIRDs “are best understood as reference and synthesis products rather than as original research.” The note adds that not every paper in the series concerns aerospace systems or threat assessment, and that the summaries “should not be read as implying current validation of the concepts discussed.”

These are literature reviews commissioned from outside specialists, some solid and some far out. None of them reports a device that was built or tested, and none of them presents evidence that anyone had one.

The government’s blurb says 38 DIRDs were produced. This release contains 37. The DIA had already released 37 of the 38 through the Freedom of Information Act by March 2022. Researchers who tracked that release have said the outstanding title is a classified version of one of the others, but they have not identified which one, and neither does this release. We have not been able to verify which paper is missing.

The papers, by subject

The largest group deals with propulsion and the physics of spacetime, and this is where the program’s reputation comes from. Some of it is conventional engineering history. Space access argues that American launch programs leaned too heavily on expendable rockets descended from ballistic missiles. Laser Lightcraft nanosatellites looks at launching very small payloads with ground-based laser beams, and MHD air-breathing propulsion surveys plasma and magnetohydrodynamic control for hypersonic flight. Further out are positron propulsion, Project Orion-style nuclear pulse propulsion for crewed deep-space missions, and two papers on aneutronic fusion rockets (Part I and Part II). Then the series moves well past established engineering. It includes a survey of antigravity, a history of claims that superconductors can affect gravity, and an exploration of spacetime metric engineering. It proposes a warp drive powered by manipulating extra dimensions, treats traversable wormholes and “stargates” as physics problems, and discusses negative mass propulsion and a method for mapping negative-energy states in the vacuum. The government’s summaries of these papers are consistently cautious. The antigravity paper “deviates significantly from mainstream physics consensus.” The warp-drive paper “offers no viable engineering pathway.” The spacetime-metric paper “does not propose any mechanism” for the effects it describes.

Energy and power make up a smaller group. Inertial electrostatic confinement fusion finds the concept several orders of magnitude short of breakeven. Extracting energy from the quantum vacuum admits that no practical extraction method has been demonstrated. At the practical end are ultracapacitors and two directed-energy reviews: pulsed high-power microwave sources and the state of high-energy lasers.

The materials papers are the most conventional in the series. They cover metallic glasses, programmable matter, structural materials for advanced aerospace platforms, metamaterials, and invisibility cloaking. The cloaking paper concludes that imperfect cloaking is achievable at microwave frequencies and that perfect cloaking is not.

Sensors, computing and communications take up another handful. There are reviews of metallic spintronics and of quantum and DNA-based computing. One paper, on detecting and tracking hypersonic vehicles, is arguably the closest thing in the series to a threat-assessment product. The other two are speculative. One asks whether quantum entanglement could carry faster-than-light messages and repeatedly concedes the question is unresolved. The other proposes high-frequency gravitational-wave communications and depends on generation and detection capabilities that had never been demonstrated.

Human factors and biology account for six papers. Four of them are solid: a survey of biomaterials, a review of biosensors and BioMEMS, a study of brain-machine interfaces for controlling external devices, and an analysis of the cognitive limits on one operator controlling many unmanned spacecraft. That last paper puts the practical ceiling at about sixteen craft for simple monitoring and about four for complex operations. Two others begin from exotic premises. Cockpits in the era of breakthrough flight designs controls for craft that could control gravity and inertia, and says openly that it does not describe any existing vehicle. Anomalous acute and subacute field effects on human biological tissues compares injuries reported after close encounters with anomalous phenomena to the known effects of intense microwave exposure. The government’s summary notes that it relies on case comparisons with no physical examinations and on encounter claims “that lack independent scientific validation.”

Two papers do not fit any group. An Introduction to the Statistical Drake Equation recasts the classic estimate of communicating civilizations in terms of probability distributions. It is a methodological exercise, not an estimate. Maverick Inventor Versus Corporate Inventor asks where breakthroughs in unconventional energy and propulsion will come from, and concludes that the answer is independent, technically trained researchers working outside institutional constraints. The government’s summary points out that this profile closely resembles the people who appear to have written much of the series, so the paper ends up “validating the program’s operational model rather than neutrally assessing the innovation ecosystem.”

The gap between purpose and product

A reasonable reader will ask how a foreign-threat forecast ended up funding papers on stargates. The Statement of Objectives offers part of an answer: “spatial or temporal translation” was one of the twelve technical areas, so exotic physics was in scope from the start. The rest comes from AARO. Its 2024 history says that investigating UFOs “was not specifically outlined in the contract’s statement of work,” but that the contractor pursued UFO research anyway, with the support of the DIA program manager. That work included reviewing old Project Blue Book cases, running debriefing teams, and proposing laboratories for recovered material.

The same history says the program looked into an alleged hotspot of UAP and paranormal activity at a property in Utah owned at the time by the head of the contractor. It examined reports of “shadow figures” and “creatures” and explored “remote viewing” and “human consciousness anomalies.” AARO does not name the property. It is widely identified as Skinwalker Ranch in the Uinta Basin, which Robert Bigelow owned from 1996 until he sold it in 2016, and whose later investigations are covered on a separate page. AARO states that the DIA “did not seek, nor specifically authorize, this work.” None of that activity shows up in the 44 contract and DIRD records released in 2026. It comes from AARO’s account and from the program’s participants.

A program with two names

The public learned about the program on 16 December 2017, when The New York Times published “Glowing Auras and ‘Black Money’: The Pentagon’s Mysterious U.F.O. Program.” The story named it the Advanced Aerospace Threat Identification Program, or AATIP, a revelation covered here, and it came with Navy cockpit videos including the 2004 Nimitz encounter. It reported the $22 million figure and linked the work to Bigelow’s company in Las Vegas.

The name caused years of confusion. AARO’s report says the two names “have been used interchangeably … including on official documentation,” but that “unlike AAWSAP, AATIP was never an official DoD program.” In AARO’s account, after AAWSAP was cancelled, the AATIP label was used by an informal community of interest within the Defense Department that studied military UAP sightings as a side duty, an effort that “had no dedicated personnel or budget.” The contract released in 2026 settles one part of the argument: the funded, contracted program was AAWSAP.

The papers came to light after that. In January 2018 the DIA gave Congress a list of the 38 DIRD titles. The list was released under the Freedom of Information Act in January 2019, and most of the papers followed through FOIA over the next three years. The 2026 release puts the series alongside the contract that paid for it.

What AARO concluded

AARO’s verdict is more restrained than either the program’s supporters or its critics tend to be. The contract “produced exploratory papers addressing the 12 scientific areas,” and those papers “were never thoroughly peer reviewed.” AARO says it “has yet to uncover any other substantive UAP case work” by the program. It records that shortly before cancellation, the contractor proposed a public-relations campaign of staged “intellectual debates” built on the assumption that “E.T. visitations are true.” It says the program ended in 2012 because of DIA and Defense Department concerns, and that supporters then tried and failed to revive it at the Department of Homeland Security under the name KONA BLUE. More broadly, AARO wrote that the combined findings of every U.S. government investigation to date “have not found even one case of UAP representing off-world technology.”

Read on their own terms, some of the papers are competent surveys of real fields, and a few are thoughtful. The most exotic ones are serious attempts to work through what general relativity and quantum field theory do and do not forbid. None of them documents a working device, a recovered craft, or a test. The contract file matters for a related reason: it is ordinary procurement paperwork, and it lets the program be described from its own records instead of from the story that grew up around it.
