(Later 377th Flight Test Missile Maintenance Squadron) Air and Space Outstanding Unit Award
The 377th Flight Test Maintenance Squadron is an active United States Air Force unit assigned to the 377th Test and Evaluation Group at Vandenberg Space Force Base, California, where it supports test and evaluation of LGM-30 Minuteman and LGM-35 Sentinel missiles. The squadron was first active during 1958 as the 394th Missile Training Squadron, training missile personnel for intercontinental ballistic missiles. It was activated again in 1960 as the 394th Strategic Missile Squadron, and continued training with more modern missiles. In 1976, its mission changed to maintaining missiles used for testing, becoming the 394th Intercontinental Ballistics Missile Test Maintenance Squadron. It became the 394th Maintenance Support Squadron in 1991, and was inactivated in 1993. It was reactivated in 2022 with its current name and mission.
Mission
The squadron provides maintenance support for intercontinental ballistic missile initial operational test and evaluation and force development evaluation programs. It supports ground and flight tests to collect, analyze, and report performance, accuracy, and reliability data for the Joint Staff, United States Strategic Command, the Air Staff and Air Force Global Strike Command.
History

The squadron was first activated at Vandenberg Air Force Base, California in April 1958 as the 394th Missile Training Squadron and assigned to the 704th Strategic Missile Wing. Its mission was to conduct training for SM-65 Atlas intercontinental ballistic missile operations and maintenance.s. In December of that year, the squadron and the 392d Missile Training Squadron, which was the training unit at Vandenberg for intermediate range ballistic missiles, were inactivated and replaced by a single training squadron, the 576th Strategic Missile Squadron.

The squadron was organized at Vandenberg a second time in July 1960 as the 394th Strategic Missile Squadron and assigned to the 1st Missile Division. The squadron supported all LGM-30 Minuteman test launches. In 1976, its mission shifted to maintenance support for missile testing, and it became the 394th Intercontinental Ballistics Missile Test Maintenance Squadron.
In September 1991, when the Air Force reorganized under the Objective Wing system, the squadron became the 394th Maintenance Support Squadron, and was reassigned to the 310th Maintenance Group. A year later, it was inactivated, and its functions were transferred to the 30th Logistics Support Squadron.
Operational missile testing at Vandenberg had been conducted by the 576th Flight Test Squadron since 1991. Air Force Global Strike Command determined that with the development of the LGM-35 Sentinel missile, the 576th needed expansion, and activated the 377th Test and Evaluation Group. The 394th Squadron was redesignated the 377th Flight Test Missile Maintenance Squadron and again activated at Vandenberg in November 2022
