Electronic Warfare Aircraft (EWA) remain critical components across the modern, digital-centric battlespace, actively blinding enemy radar and Command and Control (C2) services through advanced onboard systems. The United States Air Force (USAF) has made extensive use of such platforms for decades and is set to introduce its latest "tool in the toolbox" through adoption of the EC-37B "Compass Call". The EC-37B underwent its Initial Design Review (IDR) in 2017 and is expected to be formally introduced into active service by the USAF during 2024.

The new aircraft succeeds an aging fleet of EC-130H Compass Call platforms in same over-battlefield role, this older aircraft based in the Lockheed C-130 Hercules tactical transport.

While the airframe of the EC-37B is an original design from BizJet-maker Gulfstream Aerospace, the project (and applicable electronics) is headlined by defense industry powerhouse BAe Systems with integration handed by L3Harris (L3 Communications).

At its core, the aircraft is a modified Gulfstream G550 twin-jet and retains its exceptional straightline performance and operating range. The design sees a traditional side-by-side cockpit arrangement set aft of a sloped nosecone assembly, tubular fuselage, and "T-style" tail unit with high-mounted horizontal planes. The mainplanes are low-mounted along the fuselage sides and capped by fuel-saving winglets. A retractable, all-wheeled undercarriage is used for ground-running. The engines are set well-aft in the design along wingstubs positioned behind the passenger cabin (as a noise reduction measure) and ahead of the vertical tail plane.

The G550 series was introduced to market in 2004 and continues to see widespread global use today (2023).

In the EC-37B, the aircraft adds fuselage "bulges" to either side in help increased internal volume and incorporates a series of antenna and sensor protrusions along its ventral and dorsal lines. Over the nose is identified another sensor fit, this one forward-looking. Systems modularity will be in-built allowing the base EC-37B aircraft to be upgraded as technology (and USAF operating budget) allow in future decades.
