Members of the British Royal Air Force and the US Air Force are currently at the Royal Australian Air Force (RAAF) bases in Darwin and Tindal in Northern Australia for a multinational air combat exercise.

Part of the exercise is training on the Boeing E-7A Wedgetail Airborne Early Warning and Control aircraft, which was developed by the RAAF.

Defense News reported that the US and British air forces have ongoing acquisition programs to purchase the E-7A, which is based on a commercial Boeing 737 airliner and fitted with a Northrop Grumman multi-role electronically scanned array radar on a fairing on top of its fuselage.

E-3 Sentry vs E-7A Wedgetail

Air Battle Manager Maj. Christopher Dunn of the United States Air Force told Defense News that the transition to the Wedgetail E-7A from the current Boeing E-3 Sentry was relatively seamless due to the similarity in user interfaces on both platforms.

Dunn, who is on a three-year tour with the Australian air service, explained that the main benefits of the Wedgetail E-7A were the modern, electronically scanned array radar and communications suite and the improved reliability of the newer airframe.
