3531st Periodic Maintenance Squadron

The 3531st Periodic Maintenance Squadron was established in the early 1950s as part of the United States Air Force’s strategic effort to enhance aircraft readiness during the Cold War. Based at Amarillo Air Force Base, Texas, the squadron specialized in scheduled, in-depth maintenance and overhaul of bomber and tanker aircraft assigned to Strategic Air Command. Its highly trained personnel ensured the operational reliability of key assets such as the B-47 Stratojet and KC-97 Stratofreighter. The unit played a vital role until the base's closure and subsequent squadron inactivation in the late 1960s, leaving a legacy of technical excellence and mission support.
