Cactus Flat, SD – The Delta-01 Launch Control Facility will be closed to public tours for two months, beginning Monday, September 18, 2017 to allow replacement of critical infrastructure.
During the closure of Delta-01, visitors will be able to visit the Delta-09 missile silo and the visitor center during their regularly scheduled hours. Beginning September 18, 2017 and throughout the remainder of the month, ranger programs will be held in the visitor center theater twice daily at 10:00 a.m. and 1:00 p.m. A ranger program will be conducted at the Delta-09 missile silo daily at 2:00 p.m.
The closure of Delta-01 is to allow for a complete replacement of the fire suppression system inside the historic structure. The existing system utilizes components original to the building that were installed during its construction in 1962 and have aged well beyond their intended operational lifespan. “This project is necessary to ensure the building and all the historic artifacts within remain protected so we can safely continue to offer public tours now and into the future,” said Superintendent Eric Leonard, “We regret the inconvenience to the visiting public during the fall season.” To stay informed about this project and other news about Minuteman Missile National Historic Site, the public can visit our Facebook page or the park website for more information.
Minuteman Missile National Historic Site’s headquarters and visitor center is located off of exit 131, Interstate 90. The park consists of three sites along a fifteen mile stretch of Interstate 90 in Western South Dakota. Authorized by Congress in 1999, Minuteman Missile National Historic Site preserves components of the Minuteman II intercontinental ballistic missile system, interpreting the deterrent value of the land-based portion of America’s nuclear defense during the Cold War era and commemorating the people and events associated with this recent period of American history.
