On April 2, 2026, U.S. Central Command confirmed the first operational deployment of the EA-37B Compass Call, formally adding the aircraft to the asset list for Operation Epic Fury. Two aircraft, callsigns AXIS41 and AXIS43, departed Davis-Monthan Air Force Base, Arizona, crossed the Atlantic with a stop at RAF Mildenhall, and are en route to the Middle East. The likely trigger: reports that two legacy EC-130H Compass Call aircraft may have been damaged in Iran's March 27 missile and drone strike on Prince Sultan Air Base, Saudi Arabia. The Air Force's newest and most capable electronic warfare platform has been pushed into its first combat zone ahead of its planned full operational availability.

The Compass Call mission has been a fixture of U.S. air campaigns since the 1980s. Flying heavily modified C-130 Hercules airframes designated EC-130H, the 55th Electronic Combat Group developed the core mission: stand-off jamming of enemy command and control communications, radar systems, and navigation networks. The objective is to blind and deafen an adversary's ability to coordinate, degrading air defenses, disrupting missile launches, and breaking down the kill chains that threaten friendly aircraft. For decades the EC-130H performed this mission exceptionally, but its age, limited speed, and relatively low operating altitude increasingly placed it at risk in modern threat environments. The Compass Call Rehost program, initiated in 2018, moved the entire mission suite onto the Gulfstream G550 business jet airframe, a platform already proven in the intelligence and surveillance world. The first EA-37B was delivered to Davis-Monthan in August 2024. By May 2025 the 43rd Electronic Combat Squadron was flying training sorties. By April 2026, the aircraft was in a combat zone.

The operational significance of this deployment goes beyond a simple platform swap. The EA-37B operates at significantly higher altitude and higher speed than the EC-130H, extending its stand-off range and placing it outside the engagement envelope of many surface-to-air missile systems that could threaten its predecessor. In Operation Epic Fury, the aircraft is expected to work in close coordination with RC-135 Rivet Joint signals intelligence aircraft already operating in the theater, pairing the RC-135's ability to detect and geolocate enemy emitters with the EA-37B's ability to jam them. That combination represents a genuinely new capability in airborne electromagnetic warfare, and this deployment is its first real-world test.

If you see an EA-37B, the recognition features are distinct. The airframe is a Gulfstream G550 business jet: twin rear-mounted engines, a clean swept wing, and a narrow fuselage, but the modifications are immediately obvious. Large conformal antenna arrays are mounted along both sides of the forward fuselage, housing the Compass Call electronic attack suite. There is no external weapons pylons, no gun ports, no hardpoints. The aircraft looks, from a distance, like an executive jet that has grown antenna panels, which is exactly what it is. At closer range, the mission equipment fairings distinguish it from any civilian G550 variant.

The EA-37B Compass Call is featured in our US Armed Forces Aircraft Recognition Playing Cards deck, alongside the RC-135 Rivet Joint, the E-3 Sentry, and the full cast of special mission aircraft now operating over the Middle East. If you're watching this conflict and want to know what's in the sky, that's the deck to have.
