Boeing will transfer two 737-700 airframes to STS Aviation in Birmingham for E-7 conversion in 2026. Boeing will have two rapid-prototype E-7 Wedgetail Airborne Early-Warning & Control (AEW&C) aircraft converted in the United Kingdom, marking a rare instance of U.S. Air Force aircraft work being performed on British soil. Debate Over E-7 ProcurementThe E-7’s path to the adoption by the U.S. Air Force still remains contested. Open QuestionsThe UK conversion work can be considered a tactical win for British industry and for Boeing’s short-term production plan. While the two E-7 rapid prototypes might be completed following this deal, the E-7 program will continue to be shaped by ongoing debate until the final decision is taken about an airborne or spaceborne AEW capability.
