Declassified UAP audio — Pentagon UFO recordings.
16 audio recordings
UAP Browser preserves 16 audio recordings declassified under the PURSUE program by Department of War and NASA, recorded between 1952 and 1972. These are mission and cockpit communications — radio transmissions between aircrew, controllers and ground stations — released as part of a case file that also includes the reported incident date, location and, where the source material supports it, a transcript of what was said. Each audio page links to the official file identifier and the same location, date and agency metadata used across the rest of the archive, so a recording can be cross-referenced against related videos, documents or images from the same mission. None of these files are hosted by or affiliated with the Department of War; they are mirrored here exactly as released, to make search and citation practical. Browse the recordings by decade below, or use the case index, map and timeline to follow a single incident across every format it was released in.
