381 MIMS PTS

The 381st Missile Maintenance Squadron (381 MIMS) and Propulsion Technical Squadron (PTS) were specialized units within the United States Air Force, primarily associated with the maintenance and technical support of intercontinental ballistic missiles (ICBMs) during the Cold War era. Activated at Vandenberg Air Force Base, California, the 381 MIMS provided critical missile maintenance, while the PTS focused on propulsion systems, ensuring the operational readiness of the nation’s strategic deterrent forces. Both units played a vital role in supporting training, testing, and operational launch capabilities for Minuteman and other missile systems. Their contributions were integral to the success of the USAF’s missile operations and national security until subsequent reorganizations and inactivations as the missile mission evolved.
