Based on a C-130H airframe, the EC-130H Compass Call is an airborne communications jamming platform operated by the Air Combat Command's (ACC) 55th Electronic Combat Group (55 ECG) at Davis-Monthan AFB, Tucson, Arizona. The EC-130 Compass Call aircraft attempts to disrupt enemy command and control communications and limits adversary coordination essential for enemy force management. The Compass Call system employs offensive counterinformation and electronic attack capabilities in support of U.S. and Coalition tactical air, surface, and special operations forces. The EC-130H was used extensively in the Gulf War and Operation Iraqi Freedom, disrupting Iraqi communications at both the strategic and tactical levels. It has also been used in Operation Enduring Freedom in Afghanistan and Operation Inherent Resolve against the Islamic State.
