THE DOCUMENTS

DOW-UAP-D131, “AAWSAP DIRD The Role of Superconductors in Gravity Research March 23 2010”; DOW-UAP-D132, “AAWSAP DIRD Advanced Space Propulsion Based on Vacuum Spacetime Metric Engineering March 29 2010”; DOW-UAP-D135, “AAWSAP DIRD Antigravity for Aerospace Applications March 30 2010 V2”; and DOW-UAP-D152, “AAWSAP DIRD Negative Mass Propulsion January 3 2011”: four Department of War records from the U.S. Department of War’s PURSUE Release 06, published at war.gov/ufo on 18 September 2026. The titles are the release’s, taken from the file names; the words AAWSAP DIRD, the dates in that form and the V2 are the release’s. The papers’ own titles, printed on each cover, are The Role of Superconductors in Gravity Research; Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering; Antigravity for Aerospace Applications; and Negative Mass Propulsion. Each cover is a Defense Intelligence Reference Document cover with the Defense Intelligence Agency seal, a date, an ICOD and a control number: 23 March 2010, ICOD 1 December 2010, DIA-08-1003-013; 29 March 2010, ICOD 1 December 2009, DIA-08-1003-015; 30 March 2010, ICOD 1 December 2009, DIA-08-1003-018; and 03 January 2011, ICOD 30 August 2010, DIA-08-1101-023. The four run to 16, 17, 44 and 43 pages, each with its own page numbers; this briefing cites PDF pages. Every page carries UNCLASSIFIED with FOR OFFICIAL USE ONLY struck through, except DOW-UAP-D152 p. 4, which is blank. On p. 2 of each, the author’s name is replaced by an overprinted label, AAP Person 75, 57, 58 and 72 in that order, and the AAWSA Program Manager’s by AAP Person 1 in a thin-ruled box. Neither label is a black bar, and neither carries an exemption code.

Why this one is worth your time

These four papers take on gravity directly: whether superconductors can shield or generate it, what a technology able to reshape spacetime would look like from outside, which routes to antigravity survive an order-of-magnitude estimate, and whether negative mass exists and could be put to use. They are four of the 37 papers the release files as DIRDs, DOW-UAP-D117 to D153, under the AAWSAP prefix of the contract records in Release 06 Briefing 10. Each states in its own words what it holds possible and how far its subject is from a working technology.

One page of D132 lists light bending, apparent changes of size or shape and a sudden cloaking or blinking out among the effects around a craft in engineered spacetime. The paper presents them as consequences of its physics, and this briefing reports them that way (p. 14).

What the documents say

Two sets of front matter. D131, D132 and D135 carry the series line Acquisition Threat Support on the cover, and their p. 2 names the Acquisition Support Division (DWO-3), Defense Warning Office, Directorate for Analysis, Defense Intelligence Agency, as preparing office. An Administrative Note places each in a series of advanced technology reports produced in FY 2009 under the Defense Warning Office’s Advanced Aerospace Weapon System Applications (AAWSA) Program, with comments to ATTN: CLAR/DWO-3. D152 carries the later set: the series line Defense Futures, the Technology Warning Division (DWO-4), FY 2010, ATTN: JUIAF - DI/DWO-3, and a boxed sentence defining the Defense Intelligence Reference Document as non-substantive but authoritative reference information. On its p. 2 the programme manager’s name is marked twice, once by an empty box whose label AAP Person 1 sits outside it at the right margin and once by a box carrying the same label over the first letter of AAWSA Program Manager. All of this is read from the 200 dpi images.

D131, superconductors. The paper calls itself a historical survey of the role superconductors have played in the search for laboratory-scale manipulation of gravity (p. 4). Most of it is a timeline (pp. 7 to 15) built round Evgueny E. Podkletnov’s 1992 paper on an apparent gravity shielding experiment with a spinning superconductor disk: a critique of its cryostat (p. 9); very slight apparent weight changes in several simplified replications, so close to the noise, it says, that further experimentation was not considered (p. 9); NASA experiments that failed to see the expected shielding, and a weak gravity increase its authors later showed to be the likely result of an instrumentation artefact (p. 11); and a high-voltage gravity beam whose effect, as Podkletnov described it, was a pencil falling over in the next room (pp. 11 to 12). Its author writes as a participant and reports that the author’s own replication of the 1992 experiment found a null result (p. 13). It follows Martin Tajmar’s rotating-ring measurements to a residual signal it calls unexplained (p. 14).

D132, metric engineering. Its Preface sets out the idea that empty space might be engineered to provide energy or thrust for future space vehicles, then says the energy densities required exceed what engineering can achieve by many orders of magnitude (pp. 4 to 5). Table 1 (p. 9), read from the page image because the text layer scrambles it, lists what a distant observer would see in an engineered metric: clocks faster, frequencies blueshifted, energy states raised, rulers expanded, effective light speed above c, effective mass decreased, gravity antigravitational. Section III draws what it calls corollaries for advanced aerospace craft: outside sounds redshifted below hearing, luminosity brightened into the visible (p. 12), materials hardened enough to strike water at high velocity without apparent damage, a large craft that looks small from outside (p. 13). On p. 14, under the heading REFRACTIVE INDEX EFFECTS, it says that for metric-engineered spacetime associated with exotic propulsion a number of corollary side effects “emerge as possibilities”, mimicking known refractive index effects: waviness at boundaries like heat waves off a desert floor, a light beam that bends or ends in mid-space, apparent changes in size or shape, and a sudden cloaking or blinking out consistent with strong gravitational lensing, with metamaterials named as another option. The technical requirements of the Alcubierre warp drive’s shell of exotic matter, it says, are unlikely to be met in the foreseeable future (p. 15), and it is “premature to even guess” at an optimum strategy (p. 17).

D135, antigravity. The Foreword says the paper reviews theoretical approaches to controlling gravity for aerospace propulsion and evaluates the make-or-break issues that limit them (p. 5). It puts the energy to levitate a test mass at 62.5 MJ per kilogram, 2.05 times the kinetic energy for low Earth orbit (p. 8), and then runs concept by concept: Forward’s ultradense ball and disk, not feasible (p. 8); a dipole generator needing dwarf-star-density matter in pipes as wide as a football field round a torus of kilometre dimensions (p. 11); a shell of negative energy, daunting (p. 17); dark energy, of which the solar system holds the mass equivalent of a small asteroid (p. 22); and a Casimir-cavity force, quite feeble but ripe for further exploration (p. 26). Its Conclusion (pp. 29 to 33) asks for a search for materials with large gravitational permeability and a dedicated programme on negative energy generators, expects a laboratory demonstration of the dynamical Casimir effect “before 2012” (p. 32), says Calloni’s proposal “should be funded and performed by” a high quality laboratory, and asks that Pinto’s be evaluated theoretically before an experiment is funded (p. 33).

D152, negative mass. Its Summary says it is easy to prove that negative masses are all around us, hidden behind positive masses. Freeing them with strong fields or particle energies it rules out; the other route is to mine them where nature has done the separation, in deep gravitational wells. The centre of the Moon, it says, can be reached by a tunnel, which “could revolutionize interstellar space flight” given a good supply of negative mass (p. 5). Sections 2 to 10 argue its theory, among it a disagreement with Bondi (p. 9) and a Planck aether hypothesis (pp. 18 to 22). Sections 11 and 12 turn to the Moon: negative matter gathered at its centre is more likely ultra-light, and the paper supposes a form 100,000 times lighter than steel with the strength of steel; seismic tomography from nuclear explosions set off on the surface could probably settle whether it is there (p. 37); and a tunnel would be made with nuclear and thermonuclear explosives, cooled with a liquid metal such as lithium and lined with ceramic (pp. 37 to 42). The yields, shatter radii and total energy estimate in those pages are described here and not reproduced. The Conclusion calls macroscopic bodies approaching zero rest mass a “speculative existence” (p. 42).

What the documents do not say

None uses UAP, UFO or unidentified as a word, and none uses extraterrestrial, alien, sighting or saucer (whole-word search, case-insensitive, issued text layer, the only layer of all four). UFO appears as a substring twice in D135, both times inside the surname Ciufolini (pp. 13, 40). D132’s p. 14 list is set out as possibilities that follow from its refractive index treatment of the vacuum; on that page the words observation and observations appear only in the conditional, and the page cites no sighting, report or case.

None names a contract or a tasking, and none gives a dollar figure: contract and tasking return no whole-word hit in any of the four. Each names the AAWSA Program only in its administrative note, and none prints AAWSAP. D131’s ICOD, 1 December 2010, is later than its cover date, 23 March 2010, and no page explains it.

D135’s pages carry no version marking: its cover, title page and the header and footer of all 44 pages show none, read from the page images, and its text layer has V2 once, on p. 17, where it renders the Laplace operator. The V2 is the file name’s.

Where the case connects

None of the four names a contract; the contract file, DOW-UAP-D110 to D116, is covered by Release 06 Briefing 10. DOW-UAP-D116 extends the period of performance to 12/21/2010 (D116 p. 1). D152’s cover date, 3 January 2011, falls after that day, and its ICOD, 30 August 2010, before it; neither record comments. Release 06 Briefing 24 covers the release as a whole.

Release 06 Briefing 22, on DOW-UAP-D128, points to D132’s p. 14 list as possible side effects of engineered spacetime, not reports of anything seen. Release 06 Briefing 14 covers the papers on warp drives, wormholes and negative energy, DOW-UAP-D138, D139 and D153.
