EC-130H Compass Call Electronic Attack Aircraft

The EC-130H Compass Call is one of the U.S. Air Force’s most specialized electronic warfare aircraft, designed to disrupt and disable enemy command, control, and communications systems. Based on the proven C-130 Hercules airframe, this aircraft plays a critical role in modern joint and coalition operations by targeting adversary electronic networks rather than physical targets.

Developed by Lockheed Martin and modified with advanced electronic attack systems by L3Harris, the EC-130H entered service in the early 1980s. Its primary mission is to conduct airborne electronic attack against enemy communications, radar, navigation, and data links. By degrading an opponent’s ability to coordinate forces, the Compass Call provides a major advantage to U.S. and allied air, ground, and naval units.

The aircraft operates at subsonic speeds and relies on endurance rather than speed. It carries a large mission crew that manages complex jamming and signal disruption systems during long-duration sorties. The EC-130H does not carry traditional weapons. Instead, its payload consists of powerful transmitters, antennas, and signal processors capable of targeting a wide range of frequencies.

Compass Call aircraft have been used extensively in conflicts including the Gulf War, operations in Iraq and Afghanistan, and missions against violent extremist networks. Its ability to interrupt enemy communications in real time has made it a key enabler for strike aircraft, special operations forces, and ground commanders.

Although highly effective, the EC-130H is reaching the end of its service life. The U.S. Air Force is transitioning its mission to the EC-37B Compass Call, which offers improved range, survivability, and modern systems. Until full replacement, the EC-130H remains a vital asset in U.S. electronic warfare operations.

EC-130H Compass Call Price

The EC-130H Compass Call does not have a standard unit sale price due to its highly classified systems and mission-specific modifications. Estimates place the aircraft’s conversion and system cost in the range of several hundred million US dollars per platform, including long-term support and upgrades.
