The United States Air Force has officially closed the book on a legendary chapter of electronic warfare, retiring the EC-130H Compass Call aircraft after more than 40 years of distinguished service. The final operational taxi took place on September 18 at Davis-Monthan Air Force Base in Arizona, marking a ceremonial farewell for the stalwart platform that served as the backbone of the military’s electronic attack capabilities since 1983.
The EC-130H, a specialized variant of the Lockheed Martin C-130 Hercules transport aircraft, was operated by the 55th Electronic Combat Group. Throughout its four decades of service, the aircraft played a critical role in global operations, tasked with suppressing enemy communications and jamming sophisticated radar systems. Its impact was felt in nearly every major conflict of the modern era, with the Pentagon confirming that the aircraft remained relevant until the very end, seeing action as recently as this year during the initial stages of combat operations against Iran as part of Operation Epic Fury.
Following the ceremony at Davis-Monthan—which also serves as the final resting place for the Air Force’s retired fleet—the aircraft was transferred to storage, officially ending its active-duty tenure.
The retirement of the EC-130H signals a significant technological pivot for the Air Force. The platform is being replaced by the EA-37B, a next-generation electronic attack aircraft that inherits the prestigious “Compass Call” name. While the original EC-130H was built on a turboprop transport airframe, the new EA-37B is based on the high-performance Gulfstream G550 business jet.
Air Force officials have touted the EA-37B as a massive leap forward in capability. Equipped with advanced electronic warfare suites developed by BAE Systems and integrated by L3Harris, the new platform offers superior operational flexibility. According to the Pentagon, the EA-37B can fly twice as fast and twice as high as its predecessor, allowing it to remain on station longer and reach theaters of operation with greater efficiency. Furthermore, the aircraft features modernized, high-power systems designed to neutralize the increasingly complex digital defenses of modern adversaries.
The transition to the new fleet is well underway. The first EA-37B was delivered to the Air Force in August 2024, and officials have confirmed plans to expand the fleet to a total of 22 aircraft. The program has already attracted international interest, with Italy becoming the first export customer for the platform last year, underscoring the vital importance of electronic dominance in modern warfare.
As the EC-130H retires to the desert, it leaves behind a legacy of innovation and stealthy efficacy, having successfully evolved to meet the electronic battlefield demands of four different decades. The shift to the EA-37B ensures that the “Compass Call” mission will continue, albeit at a higher altitude and a much faster pace.
