Malmstrom Museum and Air Park preserves Great Falls and Malmstrom’s World War II, Cold War and missile-wing history. Indoor exhibits cover local and base missions through military model aircraft, a World War II barracks-room reconstruction, Lend-Lease and Great Falls interpretation, uniforms and survival equipment, air-defense weapons, SAGE computing and Minuteman launch-control and missile hardware. The outdoor air park adds preserved aircraft, vehicles and weapons systems. The museum is a public destination inside Malmstrom Air Force Base: non-DoD visitors must process through the Visitor Control Center with valid government-issued identification, and non-US residents need a passport and advance clearance; current hours and tours are operator-controlled, so confirm before travel. Address: 90 Whitehall Drive (Building 102), Malmstrom AFB, Montana 59402, United States.
