The NSA’s classified in-camera affidavit by Eugene F. Yeates, Chief of Policy (filed in a US District Court in 1980 in Citizens Against UFO Secrecy v. NSA) reveals the full scope of what the NSA found and withheld. NSA located 239 UFO-related documents in total. 79 were from other agencies (CIA, DIA, etc.) and referred back to them. Of the remaining 160 NSA documents, 156 are COMINT (communications intelligence) reports — intercepted foreign government military communications produced between 1950 and 1979. What are these intercepts? The affidavit explains: radar operators from foreign militaries reporting unidentified objects on their radar screens in real time. In one specific case, a 1971 intercept captures two aircraft and a ground controller reporting “a phenomena in the sky north of [REDACTED].” 109 documents report on intercepted communications between radar operators and a central control point — foreign air defense networks reporting UAPs as they tracked them. The identity of the foreign nations whose communications were intercepted is classified. All 156 COMINT reports remain withheld. The NSA successfully argued in court that disclosing them would reveal signals intelligence sources and methods — effectively, the NSA was watching foreign militaries watching UAPs.
