F.E. Warren AFB ICBM Interference — USAF Security Report

In October and November 1976, USAF Strategic Air Command security police at F.E. Warren Air Force Base, Wyoming — home of the 90th Strategic Missile Wing with 200 Minuteman III ICBMs — filed multiple formal reports of luminous unidentified craft operating at low altitude over the missile launch facility areas. The objects were observed hovering near and moving between missile silo sites. Launch control officers manning the capsules reported anomalous data on missile status panels during periods when UAPs were reported above ground. Security police officers who attempted to approach the objects described them accelerating and disappearing when pursued. The incidents were reported up the Strategic Air Command chain and formal classified reports were prepared. The pattern at Warren paralleled simultaneous incidents at Malmstrom, Minot, and Loring AFBs in the same period — forming part of the documented 1975–1976 pattern of UAP incursions over US nuclear weapons facilities. The classified SAC reports were released through FOIA requests, with several key documents now available through the National Security Archive at George Washington University. The cases were also featured in the declassified USAF history of the Strategic Air Command.
