The role of the Compass Call is to disrupt enemy command and control communications, radars, and navigation systems, significantly hindering adversary coordination as part of the Counter-Command, Control, Computers, Communications, Cyber, Intelligence, Surveillance, and Reconnaissance Targeting (Counter-C5ISRT) mission.[2] The jet will be able to conduct jamming of radars, electronic systems and communications. It will thus be able participate in Suppression of Enemy Air Defenses (SEAD) missions by disrupting an enemy’s ability to coordinate sensors and use weapon batteries that target friendly aircraft.[1]
EA-37B are Gulfstream G550 business jet airframes modified with electronic warfare equipment by L3Harris. The most distinctive feature are the large antenna arrays conformally mounted on either side of the fuselage ; these are based on the radar arrays found on the G550 CAEW (Conformal Airborne Early Warning).[3] The aircraft has gone through multiple "Baseline" iterations throughout it's development, with Baseline 4 being the latest. It incorporates BAE Systems' Small Adaptive Bank of Electronic Resources (SABER) technology.[4]
Among the equipment also found on the aircraft are : Network Centric Collaborative Targeting (NCCT) systems; System Control and Monitoring subsystems; Radio Frequency Receiver (RFR) subsystems; Software-defined Radio (SDR) subsystems; Counter Radar Assembly; Array Panels; AN/ARC-210 RT-2036 radios; KG-250 In-line Network Encryptors; KY-100 Narrow/wideband Terminals; KIV-77 Mode 4/5 Identification Friend or Foe (IFF); AN/PYQ-10C Simple Key Loaders.[5]
On 23 October 2018, Secretary of the Air Force, Heather Wilson, approved Air Combat Command's request to replace the EC-130H Compass Call aircraft from the 55th Electronic Combat Group (ECG) located at Davis-Monthan AFB, Arizona, with EA-37B aircraft (then known as EC-37B). The basing decision memorandum was signed on 15 November 2018. The first airframe was delivered to the air force in September 2023 for evaluation and testing.[6]
On 23 August 2024, the first ready aircraft (serial number 19-5591) was delivered to Davis-Monthan AFB to begin pilot training.
Originally designated EC-37B, as an electronic warfare version of the C-37B transport jet under the tri-service aircraft designation system. The designation was officially changed to EA-37B on 14 November 2023[7] to better reflect the aircraft's role and capabilities although the name change had been hinted at before.[8] The new designation does however conflict with that of the unrelated and long retired A-37 Dragonfly, itself a non-systematic designation.
