South Dakota Air & Space Museum

The South Dakota Air & Space Museum boasts an extensive collection of artifacts and documents that capture the distinguished history of Ellsworth Air Force Base, the 44th Strategic Missile Wing, and the 28th Bomb Wing throughout the Cold War. Ellsworth AFB played a crucial role in national defense during this time period with an arsenal that included bombers such as the B-29 Superfortress, B-36 Peacemaker, B-52 Stratofortress, and B-1 Lancer along with Intercontinental Ballistic Missiles including the Titan I and the Minuteman. The museum includes examples of the B-29, B-52, B-1, and both the Titan I and the Minuteman. In addition, the museum offers tours of an intact Minuteman Missile Launch Facility (missile silo) that was used to train maintenance personnel from the 1960s through the 1990s. This silo, which includes an inert training missile, provides visitors a rare opportunity to go inside an underground launch facility and get a feel for what it was like during the years these powerful missiles were on alert defending the nation.
