According to released documentation, the possible upgrades may involve replacing the Northrop Grumman MESA radar, the electro-optical observation system, the electronic support measures (ESM) system, self-defence suite, Link 16 module, JWICS communications, IFF systems, BMC2, and TDL components. A contract for these modifications could be signed in 2027, covering both already delivered aircraft and those yet to be ordered.
One reason for initiating the analytical phase is the ageing baseline configuration of the E-7A, which is now around 20 years old. “There has been significant technological advancement during this period, enabling increased capabilities in several equipment areas that can be integrated into the aircraft,” the Department indicated.
The US Air Force plans to operate a fleet of 26 E-7A Wedgetails to replace its ageing E-3 Sentry aircraft. Boeing is currently assembling the first of the two E-7As ordered so far by the Department of Defense.
