The EA-37B Compass Call: Delivering the Future of Electronic Warfare Today

Keeping Compass Call Flying for More Than 20 Years

The Compass Call mission has provided our U.S. and allied forces with disruption of enemy communications, radars and navigation systems for more than 40 years. The system suppresses enemy air defenses by preventing the transmission of essential information between adversaries, weapon systems and command-and-control networks.

The original Compass Call fleet was comprised of C-130 aircraft, designated the EC-130H when integrated with the EA mission system. The heavily deployed EC-130H served in every major U.S. contingency operation since the mid-1980s, and until recently, was continuously deployed to support U.S. Central Command operations in the Middle East.

L3Harris' Waco facility has provided integration and depot-level maintenance services to the legacy Compass Call fleet since 2003 - first with the integration of the EC-130H, and now with the migration of the mission system to the modified special missions, Gulfstream G550 business jet.

"It was an incredible task migrating the complex Compass Call mission system from the EC-130H into the streamlined G550 to extend the heritage of the Air Force's premier jamming fleet," said Jason Lambert, President, Intelligence, Surveillance and Reconnaissance, L3Harris. "We are proud to equip the Air Force with capabilities so it can endure in electromagnetic spectrum dominance against our adversaries."
