A released set of Defense Intelligence Agency reports shows the government paid contractors to study speculative physics alongside aerospace threat detection.
Declassified Pentagon records show the U.S. government funded research that ranged from advanced propulsion concepts to theoretical work on traversable wormholes and invisibility cloaking, as well as efforts tied to tracking unexplained aerial incidents.
The material centers on a set of 38 research titles associated with the Advanced Aerospace Threat Identification Program and related work. The list and many of the underlying technical papers became public through Freedom of Information Act disclosures handled by the Defense Intelligence Agency.
A list of 38 studies, then the studies themselves
The public record begins with a five-page list of study titles released by the Defense Intelligence Agency in response to a FOIA request by Steven Aftergood, who led the Federation of American Scientists’ project on government secrecy for three decades. The titles read like a catalog of frontier research: space-time metrics, exotic propulsion, advanced materials, and sensing and tracking problems associated with fast-moving objects.
In the years that followed, the DIA’s FOIA Electronic Reading Room posted many of the associated “Defense Intelligence Reference Documents,” a set of contractor-produced reports written for the agency under an umbrella that appears in the documents as the Advanced Aerospace Weapon System Applications program. The reports carry DIA document identifiers and administrative notes describing them as part of a series of advanced technology studies produced in fiscal year 2009.
The result is a clearer view of what the government actually bought: not proof of alien craft, but funded work exploring whether certain physical ideas could be made relevant to national security problems, alongside more conventional interest in detection, tracking, and propulsion.
Wormholes, warp drives, and what the words mean in physics
Several reports focus on concepts that are familiar to science fiction readers but treated, in the documents, as mathematical and engineering questions rather than narrative devices.
One study, “Traversable Wormholes, Stargates, and Negative Energy”, describes wormholes in the language of general relativity and notes that “traversable” models typically require forms of negative energy density that are not available in ordinary matter. In mainstream physics, wormholes are allowed as solutions to Einstein’s equations under certain conditions, but keeping one open and stable is the hard part, and the needed “exotic matter” remains hypothetical.
Another, “Warp Drive, Dark Energy, and the Manipulation of Extra Dimensions”, is credited in the document to Richard Obousy and Eric W. Davis. The report frames “warp drive” ideas around proposed space-time geometries that could, on paper, allow effective faster-than-light travel without locally exceeding the speed of light, but it also emphasizes large energy requirements and unresolved constraints. In standard cosmology, “dark energy” is the term used for the component inferred from the observed accelerated expansion of the universe, not a fuel source, and the report treats it as a speculative hook for thinking about unusual energy densities rather than a practical engineering input.
A third example is “Invisibility Cloaking: Theory and Experiments”, authored in the document by Ulf Leonhardt. In academic optics, cloaking research is typically discussed in terms of metamaterials and “transformation optics,” methods that steer light around a region so an object does not scatter radiation in the usual way. Leonhardt has been a prominent researcher in that area, including work and public explanations of how limited forms of cloaking can be constructed for certain wavelengths and geometries, as summarized by the Weizmann Institute of Science during his time there.
The reports do not claim these concepts were achieved. They read as feasibility and horizon-scanning exercises: what the math says, what laboratory demonstrations exist at small scale, what obstacles remain, and what would be required for anything operational.
The program behind the paperwork
The study list is tied in public reporting and in FOIA-released material to the Advanced Aerospace Threat Identification Program, often shortened to AATIP. The program became widely known after reporting by major outlets in late 2017, and more recent government reviews have discussed how AATIP related to the DIA’s Advanced Aerospace Weapons System Application Program, commonly called AAWSAP.
A key point in the released documents is scope. While AATIP is often described in public conversation as a UFO-investigation effort, the paper trail shows a parallel interest in advanced technologies that, if real, could change aerospace capabilities: novel materials, new sensing approaches, and power and propulsion concepts that sit at the edge of known physics. Some of that work looks like classic defense “what if” research, the kind agencies commission to understand whether a rival’s breakthrough claim is nonsense, plausible, or a long-shot worth tracking.
The same files also support the narrower claim at the center of the story: the government did not merely collect sighting reports. It paid for technical writing about wormholes, warp metrics, and cloaking, alongside reports on detection and tracking problems that would matter whether the target is foreign hardware, a misidentified object, or something genuinely unexplained.
Aftergood’s view: strange titles, real money
Aftergood, whose FOIA work helped bring the list to light, argued that the titles alone raised questions about judgment and priorities. He later told reporters:
“These are the kinds of topics you pursue when you have more money than you know what to do with.”
That line captured a basic tension running through the files. Many of the topics are “high risk” in the purest sense: the physics may be incomplete, the engineering hurdles may be overwhelming, and practical payoffs may never arrive. Yet in national security research, the justification for looking anyway can be straightforward. A small investment can be used to map what is known, test whether the idea has any experimental footing, and build vocabulary for assessing claims that might surface later in intelligence channels.
What the files do, and do not, show
The declassified material does not establish that alien craft exist, nor does it demonstrate that the government built a wormhole, created a true invisibility cloak, or found a way to extract “zero-point energy” for propulsion. What it does show is more mundane and, in some ways, more consequential: a bureaucracy paid for work products on subjects that most people encounter first in fiction, and those work products were processed like other defense research reports, with authorship, versioning, and administrative handling.
The remaining gaps are visible in the record itself. Some material is still withheld or redacted, and the list format offers limited detail about what, if anything, moved beyond literature reviews and theoretical modeling. The DIA’s FOIA release nonetheless clarifies one central point: for a period of years, the U.S. government treated speculative physics and exotic aerospace concepts as legitimate topics for funded study, alongside efforts aimed at identifying and tracking potential aerial threats
