Titan I and Minuteman ICBM base 1962-1994. 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.

First Launch: 1965-03-01. Last Launch: 1977-04-14. Number: 2 . Location: Wyoming. Longitude: -103.1000 deg. Latitude: 44.1300 deg.

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. The first stage was loaded with only enough propellant for seven seconds of burn time and the upper stages were inert.

    Operation Long Life, the first test launch of a specially designed Minuteman test missile from an operational launch facility, was successfully concluded at Wing II, Ellsworth AFB, South Dakota. With a first stage engine designed to burn only a short time, the Long Life missile carried dummy second and third stages that were up to full operational weight. The missile landed about a mile from the silo after a first stage burn of seven seconds. 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.
