In 1963 446th Strategic Missile Sq was organized as a SAC LGM-30F Minuteman II ICBM wing. Activated in 1965, it was made operational in 1966, with 50 missiles. From 1971 - 1973, the sq converted to LGM-30G Minuteman III. These represented a significant technological advancement, having multiple independently targetable reentry vehicles (MIRVs).
In 1995, the Base Realignment and Closure (BRAC) Commission selected 321 SMW for inactivation. 446 sq transferred its alert responsibilities to 341st Missile Wing at Malmstrom Airbase, Montana. It maintained nuclear alert until deactivation in 1998, after nearly 40 years.
