The 31st Test and Evaluation Squadron is a United States Air Force unit primarily responsible for testing and evaluating weapon systems across various air, space, and cyber domains. Established in 1946 as the 52nd Fighter Wing, it has since undergone several name changes and reorganizations to assume its current designation in 1993. Based at Edwards Air Force Base in California, the squadron is part of the Air Force Test Center. Its main mission involves assessing the combat readiness and effectiveness of newly developed or modified weapon systems before they are deployed into operational units, thus ensuring the U.S. maintains a technological edge in its defense capabilities.
