Type: ICBM Base. Operator: USA. Country: USA. Latitude: 44°08' N. Longitude: 103°06'W.

Titan I and Minuteman ICBM base. On 2 January 1942 the U.S. War Department established an air base at this location for training of B-17 bomber crews. The base was shut down after the war, but was reactivated in 1947 as a B-29 bomber base. These aircraft were succeeded by the B-36 in 1949, the B-52 in 1957, and the B-1B in 1986.

In January 1962 the 44th Strategic Missile Wing was activated at Ellsworth, initially equipped with Titan 1 ICBM's. These were supplemented with 150 Minuteman 1 ICBM's in later years. By October 1971 these were replaced with Minuteman 2's. In 1991, the Cold War over, these missiles were taken off alert status. By 1994 the silos had been destroyed and the ICBM mission was over.

Ellsworth hosted the unique 'Long Life' test of a Minuteman ICBM in 1965. This was the only launch of an ICBM from an operational inland US missile site.

Ellsworth AFB Chronology and Launch Log
  • 1960 December 2 - Titan I ICBM 850th SMS activated at Ellsworth AFB Launch Vehicle: Titan 1.

  • 1962 September 28 - Titan I ICBM 850th SMS (nine missiles) declared operational at Ellsworth AFB Launch Vehicle: Titan 1.

  • 1965 February 1 - Last Titan I ICBM taken off alert status at Ellsworth AFB Launch Vehicle: Titan 1.

  • 1965 March 1 - LONG LIFE Test mission Launch Vehicle: Minuteman 1. Minuteman 1B Apogee: 1.00 km (0.60 mi). Approved by the Secretary of Defense in November 1964, 'Project Long Life' called for the short-range launch from on operational missile base of three modified Minuteman IB ICBMs to provide a realistic test for this system. Each missile would contain enough propellant for a 7-second flight and have inert upper stages and reentry vehicles. This first launch occurred on March 1, 1965, and successfully demonstrated the ability of a SAC missile crew to launch an ICBM.
