In the spring of 1993, missile combat crews served their last alerts at Delta-01. They departed as the remainder of South Dakota’s missile field was being dismantled in accordance with the 1991 Strategic Arms Reduction Treaty, which limited the number of intercontinental ballistic missiles and warheads either country could possess.
Delta-01 offers an unprecedented opportunity to see an underground control center in its original setting, and to contemplate the choices America has made to “provide for the common defense.” While the threats America faces have evolved in the generation since the end of the Cold War, the Minuteman missile remains a key component of United States nuclear deterrence. Known today as “Missile Alert Facilities,” forty-five control centers similar to Delta-01 continue to watch over missiles kept on ready alert.
Access inside the gate of Delta-01 is available on a reserved tour only. To protect the historic facilities and to provide for visitor safety, each tour is limited to six participants and a park ranger. This tour lasts forty-five minutes, beginning and ending at the entry gate. All tour participants must be able to walk and stand unassisted. All tours of the Delta-01 Launch Control Facility require advanced reservations and an amenity fee. Reservations can be made on-line or by phone, up to 90 days prior to tour date. In the summer season, tours fill up to eight weeks in advance.
We hope you enjoyed your walk to the gate. You can continue your visit at the Minuteman Missile National Historic Site Visitor Center located 4 miles east of here at exit 131. There you can get more information on tours, watch the orientation film, explore exhibits, and a bookstore. Be sure to also visit the Delta-09 missile silo located 10 miles west at exit 116.
