DOW-UAP-D107 is a declassified Air Force Systems Command technical report reviewing non-conventional lifting bodies and theoretical boundary-layer control concepts in relation to reported UAP characteristics. The document was declassified and released publicly for the first time as part of PURSUE Release 05 on August 7, 2026. The study was finalized on September 30, 1974, at Andrews AFB, Maryland. 123
Provenance and Context
The document was produced by the Air Force Systems Command (AFSC), the organization responsible for the research, development, and acquisition of aerospace systems for the U.S. Air Force. It is held by the Department of War and was finalized as a theoretical engineering exercise, mapping the flight capabilities attributed to UAP onto known or conceptual physics and aerodynamics.3
Detailed Content / Analysis
The study examines "exotic aerodynamic configurations," analyzing non-conventional lifting bodies and boundary-layer control concepts. AFSC engineers tested whether flight characteristics commonly reported in UAP sightings, such as rapid acceleration without sonic booms and extreme maneuverability, could be explained by advanced but theoretical fluid dynamics and propulsion systems. The analysis relies on mathematical modeling of non-standard airframes rather than on any physical test article.3
What the Record Supports
The record shows that AFSC engineers ran the numbers on whether known aerodynamic theory, applied to unconventional airframe shapes, could account for the flight performance attributed to UAP. It does not describe a recovered craft or a working prototype, only a mathematical exercise in what exotic aerodynamics could theoretically achieve.3
