EC-130H Compass Call, Airborne electronic attack aircraft, Aircraft & UAVsAircraft & UAVsEC-130H Compass CallAirborne electronic attack aircraftThe EC-130H Compass Call is the U.S. Air Force's legacy airborne electronic-attack aircraft, a heavily modified C-130H that denies, degrades, and disrupts adversary command-and-control communications, radars, and navigation systems. Its mission crew operates permanently installed electronic-attack equipment for U.S. and coalition air, surface, maritime, and special-operations support, while the EC-130H fleet transitions to the EA-37B Compass Call successor.
EA-18G Growler, Carrier-capable airborne electronic attack aircraft, Electronic WarfareElectronic WarfareEA-18G GrowlerCarrier-capable airborne electronic attack aircraftThe EA-18G Growler is a Boeing-built electronic attack derivative of the two-seat F/A-18F Super Hornet, fielded to jam, detect, and attack hostile radars, communications, and air-defense networks while retaining missile carriage for suppression missions. U.S. Navy and Australian Growlers provide carrier or land-based electronic warfare support, with early combat deployment in Iraq and Libya in 2010-2011 and later documented use in 2014 Operation Inherent Resolve, Red Sea operations against Houthi forces, and the U.S.-Iran strike context.

It relays and translates voice, imagery, tactical data links, and IP-based traffic between otherwise incompatible air, ground, maritime, and coalition networks. The type entered combat in Afghanistan in 2008, CENTCOM listed it among Operation Epic Fury assets in 2026, and nine airframes had been delivered by September 2025 even as the Air Force's FY2027 posture statement planned full divestment in FY2028.

Official IAI material describes Shavit as the Nachshon fleet's SIGINT aircraft for monitoring the electromagnetic spectrum, while public image and fleet sources identify it as the earlier Gulfstream V/G500 member alongside the G550 Eitam and Oron aircraft.

NAVAIR says it entered service in 1971, served on the EA-6B Prowler before transitioning to the EA-18G Growler in 2010, and remains in use alongside Next Generation Jammer pods, including documented VAQ-133 carriage during 2026 Iran War strike operations.

Operated by Israeli Air Force 122 Squadron, it gives Israel a business-jet-based wide-area surveillance and target-generation platform documented in wartime support roles over Gaza and during Israel's 2025 operations against Iran.
