The Air Force Declassification Office maintains and publicly hosts the official declassified USAF historical document archive at secretsdeclassified.af.mil, including a dedicated Unidentified Flying Objects section. WHAT IS IN THE ARCHIVE: Actual declassified USAF records from Project Sign (1948), Project Grudge (1949), and Project Blue Book (1952-1969). Official flight intercept reports from the 1950s including cases where F-94, F-86, and F-101 pilots were vectored by radar to investigate unknown contacts. Ground Observer Corps sighting reports with corroborating radar confirmation. Cases where radar simultaneously tracked objects on multiple systems (ground radar + airborne radar + visual) — the combination Air Force Colonel Charles Brown described as “it doesn’t get any better than that.” Documented cases where UFO investigations were ordered halted — including the Malmstrom-era SAC incident where investigators were told to “stop and do not write a final report.” REPRESENTATIVE DOCUMENT TYPES: 1953 case — 54th Fighter Interceptor Squadron pilots vectored to investigate a bright red object that maneuvered and evaded jet intercept in South Dakota airspace. Multiple radar operators, pilot, and ground observers confirmed. Pilot vectored twice by NORAD, object performed evasive maneuvers. Cases spanning 1947-1969 with formal USAF evaluation codes (1A = reliable source, piloted aircraft sighting). PROJECT MOONDUST documents: International crash recovery operations. SIGNIFICANCE: The USAF’s own officially declassified records confirm what whistleblowers have testified to under oath — decades of genuine, multi-sensor-confirmed UAP encounters involving jet intercepts, radar tracking, and unexplained flight performance. These are not leaked documents. They are the USAF’s own formally declassified archive hosted on an official .mil domain. The gap between what these documents describe and what the public has been told exists is the core of the ongoing disclosure debate.
