Members of the squadron had to complete three phases of training prior to moving overseas and entering combat. The flying personnel spent most of October in transition training with the B-24, training combat crews as well. Meanwhile, the ground echelon was acquiring, organizing and processing personnel and supplies at Wendover Field.

With the training complete and the personnel and supplies processed, the 308th Bomb Group and the 375th BS officially transferred to Fourteenth Air Force

Reactivated and redesignated as a Strategic Air Command LGM-25C Titan II ICBM Strategic Missile Squadron in 1962.

 announced that as part of the strategic modernization program, Titan II systems were to be retired by 1 October 1987. Inactivation of the sites began on 17 March 1985 when 374-8 was inactivated; the last on 15 Aug 1986 with 374-1, 374–4 and 374-2. The squadron was inactivated the same day.

After removal from service, the silos had reusable equipment removed by Air Force personnel, and contractors retrieved salvageable metals before destroying the silos with explosives and filling them in. Access to the vacated control centers was blocked off. Missile sites were later sold off to private ownership after demilitarization. Today the remains of the sites are still visible in aerial imagery, in various states of use or abandonment.

.* Location of 19 September 1980 Broken Arrow incident (see below)

Launch Complex 374-7 incident

An unfortunate sequence of events began on 18 September 1980 at Titan II Launch Complex 374-7

A 374th SMS airman was adding pressure to the second stage oxidizing tank. During an incorrect application of a 9-pound wrench socket to the pressure cap, the maintenance man accidentally dropped the socket, which fell onto the first stage and punctured the first stage fuel tank.

The fuel, unsymmetrical dimethylhydrazine, is hypergolic, meaning contact with the oxidizing agent creates instant ignition. Eventually, the crew evacuated the launch control center as military and civilian response teams arrived to tackle the hazardous situation. Early in the morning of 19 September, a two-man investigation team entered the silo. Because their vapor detectors indicated an explosive atmosphere, the two were ordered to evacuate.

At about 0300 hours, a tremendous explosion rocked the area. The initial explosion catapulted the 740-ton closure door away from the silo and ejected the second stage and its warhead out of the silo. Once clear of the silo, the second stage exploded. Twenty-one personnel in the immediate vicinity of the blast were injured. One member of the two-man silo reconnaissance team who had just emerged from the portal sustained injuries that proved fatal.

At daybreak, the Air Force retrieved the warhead and brought it within the confines of Little Rock AFB. During the recovery the Missile Wing Commander received strong support from other military units as well as Federal, state, and local officials. Arkansas’s young governor, Bill Clinton, played an important role in overseeing the proper deployment of state emergency resources.

Interestingly, the wing received some of its greatest accolades in the wake of the this disaster. Perhaps realizing the public confidence had suffered a blow, wing personnel made a stronger effort to reach out to local communities. This effort won Air Force recognition in 1983, when the wing became the first missile wing ever to win the General Bruce K. Holloway humanitarian service trophy for the year 1982. The unit also earned the Omaha trophy for 1982, recognizing it as the best in SAC.
