EC-130H Compass Call


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 electronic attack (or EA) capabilities in support of U.S. and Coalition tactical air, surface, and special operations forces. The EC-130H, EA-6B or EA-18G, and F-16CJ, form the Suppression of Enemy Air Defense (SEAD) triad. 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.
