# 39th Tactical Electronic Warfare Squadron

The squadron was the 739th Bombardment Squadron, which was activated in June 1943. After training in the United States with the Consolidated B-24 Liberator, the 739th deployed to the Mediterranean Theater of Operations, participating in the strategic bombing campaign against Germany. It earned two Distinguished Unit Citations for its combat operations. Following V-E Day, the squadron returned to the United States for conversion as a very heavy bomber unit, but was inactivated instead.
The 39th Tactical Electronic Warfare Squadron was activated at Spangdahlem Air Base, Germany in 1969, where it was assigned to the 52d Tactical Fighter Wing until inactivating in January 1973. The two squadrons were consolidated in 1985.

## History
### World War II

The squadron was first organized at Alamogordo Army Air Field, New Mexico on 1 June 1943 as one of the four squadrons of the 454th Bombardment Group. It trained with Consolidated B-24 Liberator bombers. After completing training, it left for the Mediterranean Theater of Operations on 8 December 1943.
The squadron arrived in Italy in January 1944, settling in at its combat station, San Giovanni Airfield, by the end of the month. Its primary focus was on long range bombing missions against industrial targets such as enemy oil refineries and munitions and aircraft factories. It struck transportation targets including harbors and airfields in Italy, France, Germany, Austria, Czechoslovakia, Hungary, Yugoslavia, Greece and Rumania The squadron received a Distinguished Unit Citation (DUC) for a raid on an airfield at Bad Vöslau, Austria on 12 April 1944. The squadron earned a second DUC during an attack on a steel plant at Linz, Austria, as the 454th Group led its wing through determined opposition.
The squadron also flew air support and air interdiction missions against marshalling yards, troop concentrations and rail lines for Operation Strangle. The squadron participated in the drive to Rome; Operation Dragoon, the invasion of southern France; and Operation Grapeshot, the Spring 1945 offensive in Northern Italy.
The squadron left Italy in July 1945 and reformed at Sioux Falls Army Air Field, South Dakota the following month. It was redesignated as a very heavy bombardment squadron in anticipation of training and redeployment to the Pacific, but with the Japanese surrender, it was inactivated in October.

### Air Force Reserve

The 739th Bombardment Squadron was reactivated as a reserve unit under Air Defense Command (ADC) at McChord Field, Washington in April 1947 as a Boeing B-29 Superfortress unit, where its training was supervised by the 406th AAF Base Unit (later the 2345th Air Force Reserve Training Center). However, the squadron does not appear to have been fully staffed or equipped with operational aircraft while a reserve unit. In 1948 Continental Air Command assumed responsibility for managing reserve and Air National Guard units from ADC. President Truman's reduced 1949 defense budget required reductions in the number of units in the Air Force. Continental Air Command also reorganized its reserve units under the wing base organization system in June 1949. The squadron was inactivated and its personnel and equipment were transferred to elements of the 302d Troop Carrier Wing, which was activated simultaneously.

### Cold War

The 39th Tactical Electronic Warfare Squadron was activated in April 1969 at Spangdahlem Air Base Germany in an effort to restore an electronic warfare capability to United States Air Forces Europe (USAFE). It was planned to equip the squadron with Douglas EB-66 Destroyers, but all of USAFE's EB-66s had deployed to Southeast Asia to provide jamming support for the Viet Nam War. As a result, the squadron was initially equipped with the less capable Martin EB-57 Canberra. Shortly after activation, it became possible to equip the unit with sixteen EB-66s. The squadron continued its mission at Spangdahlem until ceasing operations in December 1972. It was inactivated in January 1973 as the EB-66 was withdrawn from the Air Force inventory.
The 739th Bombardment Squadron and the 39th Tactical Electronic Warfare Squadron were consolidated into a single unit in September 1985.
