Boeing called its 737-based airborne early-warning aircraft the 737 AEW&C.
The 737 AEW&C is a military surveillance and command aircraft derived from the Boeing 737-700. Its most visible feature is a dorsal multirole electronically scanned array, commonly called the MESA radar, mounted above the fuselage. The system allows the aircraft to detect and track air and surface targets while supporting command and control operations.
Australia selected the aircraft under Project Wedgetail, and the Australian version became known as the E-7A Wedgetail. Turkey, South Korea, and the United Kingdom also selected related aircraft, though national designations and equipment differ.
A frequent mix-up is answering E-7 Wedgetail. E-7 is the military designation used for the Australian-derived system, while 737 AEW&C is Boeing’s broader program name. The aircraft is not the older E-3 Sentry, which is based on the Boeing 707 rather than the 737.
