43rd Electronic Combat Squadron

The 43d Electronic Combat Squadron is a United States Air Force unit. Its current assignment is with the 55th Electronic Combat Group, being stationed as a tenant unit at Davis-Monthan Air Force Base, Arizona as a geographically separated unit from its parent, the 55th Wing at Offutt Air Force Base, Nebraska. It operates the EA-37B communications-jamming aircraft.

The squadron is one of the oldest in the United States Air Force, its origins dating to 17 August 1917, when it was organized at Kelly Field, Texas. It later served in France as part of the American Expeditionary Force during World War I. The squadron saw combat during World War II, and became part of Tactical Air Command during the Cold War.

Mission

Along with the 41st Electronic Combat Squadron, the unit accomplishes the Compass Call mission, providing capabilities in the realm of electronic warfare for the Air Force and poised for immediate deployment to specific theater contingencies. The unit's combat mission is to support tactical air, ground and naval operations by confusing the enemy's defenses and disrupting its command and control capabilities.

The squadron flies the Lockheed EC-130H aircraft, a specially configured version of the Air Force's C-130 transport. To execute its missions, the aircraft were modified with electronic countermeasures systems, specialized jamming equipment, the capability for air refuelling, as well as upgraded engines and avionics. Modifications made to the aircraft vary between the two squadrons, to help each squadron meet its specific mission-oriented needs.

History

The 43rd has a long history beginning 17 August 1917, as the 86th Aero Squadron. It served as part of the zone of advance in France during the latter part of World War I. Then in 1935, it was an observation squadron operating as part of the Air Corps Tactical School at Maxwell Field, Alabama. Beginning 7 December 1941, the squadron conducted patrols over the Hawaiian islands.

The squadron then switched yet again. As a combat mapping squadron, the unit's aircrews flew over Japanese held islands photographing and mapping the terrain and enemy positions. The 86th prepared the way for the taking of the Marshall Islands, Wake Island, Saipan, Guam, and Iwo Jima. Finally, in 1944, the squadron made the first photographic mosaics of Tokyo. The squadron was redesigned as the 43rd Reconnaissance Squadron (Long Range Photographic) in 1945 then was inactivated in 1946.

In January 1954, the 43rd was again activated, this time at Shaw Air Force Base, South Carolina. The squadron was initially equipped with the Martin RB-57 Canberra. However, once the Air Force received enough Douglas RB-66B Destroyer to equip more than a single squadron, the squadron transitioned to the Destroyer. It accomplished a night photographic mission. The unit was inactivated in 1959.

Redesignated the 43rd Electronic Combat Squadron, the unit was activated 6 June 1986, at Sembach Air Base, Germany. It served in Europe until 1991, then came to Davis-Monthan Air Force Base and the 355th Wing on 1 May 1992, as the sister squadron to the 41st. The 43rd earned a combat streamer for its duties in World War I and six more for missions flown in the Pacific during World War II.

The squadron began converting to the L3Harris EA-37B Compass Call, with the first plane being delivered on 23 August 2024 to begin pilot training. It flew its first EA-37 mission with a full mission crew in early May 2025. The EA-37B is a wide-area airborne electromagnetic attack weapon system. It uses a heavily modified version of the Gulfstream G550 airframe, and will replace the EC-130H as a more modern and cost-effective aircraft. By the time this mission was flown, ten of the squadron's fourteen EC-130H aircraft had been divested.
