The 513th Electronic Warfare Squadron (513 EWS) is a United States Air Force unit assigned to the 53d Electronic Warfare Group, stationed at Eglin Air Force Base, Florida.


The 513 EWS is a joint-service unit, and will serve as the sole Department of Defense provider of electronic warfare support for the F-35 joint strike fighter. It will operate the $300 million United States Reprogramming Laboratory, that tests all aspects of the joint strike fighter's electronic warfare capability. Half of the staff will be Airmen, while the other half will consist of Navy and Marine members.


Established in the Middle East during late 1942 to aid British Forces during the Western Desert Campaign. Initially equipped with obsolete B-17C/D Flying Fortresses transferred from Tenth Air Force. Replaced with B-24 Liberators flown from Florida via South America; over to then across Central Africa then north to Egypt in early 1943. Became part of United States Middle East Air Forces (USMEAF), later Ninth Air Force.

Operating from bases in British Palestine, Egypt, Libya and Tunisia, attacked shipping in the Mediterranean and harbor installations in Libya, Tunisia, Sicily, and Italy to cut enemy supply lines to North Africa. Struck airdromes, marshalling yards, and other objectives in Sicily and Italy after the fall of Tunisia in May 1943. Reassigned to Fifteenth Air Force in late 1943, and moved to southern Italy. Squadron flew long range strategic bombardment missions to targets in Italy, France, Germany, Czechoslovakia, Austria, Hungary, and the Balkans to bomb factories, marshalling yards, oil refineries, oil storage facilities, airdromes, bridges, harbors, and other objectives.

After the German Capitulation in May 1945, returned to the United States; was re-equipped with B-29 Superfortress bombers and trained under Second Air Force for deployment to the Pacific Theater. However, with the Japanese Capitulation in August, the training ended and most personnel demobilized by the end of October. Remained in active status but not fully manned or equipped, and subsequently inactivated in early 1946 due to budget restrictions.

Not manned or equipped, 23 May 1947-20 Sep 1948. Practiced electronic countermeasures with B-29 aircraft from c. 1952 until conversion to B-47 Stratojet jet medium bombers in 1954. Between 1954 and 1965, the 513 Bombardment Squadron flew a long series of simulated combat bombardment missions to maintain readiness as a unit of the Strategic Air Command, testing electronic warfare devices and radar techniques, using B-47 and EB-47 aircraft. Inactivated in 1965 with the retirement of the B-47.

Between 1992 and 1997, conducted operational test and evaluation of B-52, B-1, and KC-135 aircraft and support systems.

Activated in Apr 2010 with an electronic warfare mission, reprogramming the F-35.
