The EC-130H Compass Call is an airborne tactical weapon system using a heavily modified version of the C-130 Hercules airframe. The system disrupts enemy command and control communications and limits adversary coordination essential for enemy force management. The Compass Call system employs offensive counter-information and electromagnetic attack (EA) capabilities in support of U.S. and coalition tactical air, surface, and special operations forces. Programmed upgrades have expanded its mission by procuring a secondary EA capability against early warning and acquisition radars. The EC-130H continuously tests new capabilities and tactics to respond to emerging threats and requests from combatant commanders.

The EC-130H aircraft carries a combat crew of 13 people. Four members are responsible for aircraft flight and navigation (aircraft commander, co-pilot, navigator and flight engineer), while nine members operate and employ the EA mission equipment permanently integrated in the cargo/mission compartment. The mission crew includes the mission crew commander (electromagnetic warfare officer), weapon system officer (electromagnetic warfare officer), mission crew supervisor (an experienced cryptologic linguist), four analysis operators (linguists), one acquisition operator and an airborne maintenance technician.
