The 41st Electronic Combat Squadron was activated at D-M in July 1980 and the 43d Electronic Combat Squadron was activated at D-M April 1, 1992. Accomplishing the Compass Call mission, both squadrons provide vital capabilities in the realm of electronic warfare for the Air Force and are 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. However, they each have a different area of responsibility. Both squadrons operate the EC-130H aircraft, a specially configured version of the Air Force's proven C-130 transport. To execute its unique missions, the aircraft were modified with electronic countermeasures systems, specialized jamming equipment, the capability to aerial refuel, 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.
