Malmstrom AFB ICBM Shutdown Wave 1975

In early November 1975, following a series of earlier incursion reports at other US SAC bases, Malmstrom Air Force Base experienced multiple nights of UAP activity that brought Strategic Air Command to elevated alert. Montana NORAD Sector radar tracked unidentified contacts entering Malmstrom's restricted airspace. Base Security Police reported an orange-red luminous orb hovering over a Minuteman ICBM launch control complex. The base commander submitted an urgent message to Pacific Command and the Joint Chiefs of Staff. SAC's Security Service was mobilized for the incursions. The 1975 Malmstrom incidents form part of a documented pattern of UAP incursions at nuclear-weapons-related SAC facilities that extended from 1967 through the 1970s. Declassified SAC documents obtained through FOIA show that senior USAF commanders were sufficiently concerned about the pattern to request additional countermeasures authority. The 1975 events are distinct from and in addition to the famous 1967 Echo Flight missile shutdown incident at the same base.
