During World War II, in 1942 the US Army Air Corps established a Boeing B-17 Flying Fortress training base just west of Lewistown to train aircrews for missions in North Africa and Europe. The former airbase is now the Lewistown Municipal Airport, which is home to the last remaining Norden bombsight storage facility, used to keep the device safe from theft by enemy spies during World War II . The city park displays a Minuteman III ballistic missile.
