NSA Releases 334 Pages of Formerly Top Secret UMBRA UAP Records After Disclosure Foundation FOIA Appeal

The Disclosure Foundation announced on 18 May 2026 that the National Security Agency had produced a 334-page tranche of historical Unidentified Anomalous Phenomena records, with many entries previously bearing the TOP SECRET UMBRA classification marking, one of the most restrictive signals-intelligence compartments in the United States classification system. The production responds to a Disclosure Foundation administrative FOIA appeal whose procedural lineage traces to a 1980 watchdog lawsuit against the agency, in which classified affidavits were submitted in camera and the underlying intelligence material was withheld in full. Specific entries highlighted in the initial review include an object 'spherical or disc-like in form, brighter than the sun' and roughly half the moon's diameter, an object described as 'going up and down vertically' with 'white-bluish luminous light' and 'erratic turning movements' assessed by witnesses as 'impossible to be an aircraft' (p. 330), and a low-altitude object showing two yellow lights that silently changed heading from north to west (p. 314). Substantial NSA redactions remain on later 1960s material, and the Foundation's legal team has flagged plans to challenge them. This is the first significant non-PURSUE federal UAP document release of 2026 and the first time the agency itself has produced this material on the public record, although NSA had previously released bibliographic indices of its UFO holdings under prior FOIA actions. The full 334-page production is hosted on the Disclosure Foundation site pending location of the agency's own copies in the NSA FOIA reading room.
