The US Air Force has awarded Boeing a $2.04-billion contract to advance the post–critical design review phase of the B-52 Commercial Engine Replacement Program, a cornerstone of the service’s long-term bomber modernization strategy. The task order covers system integration activities and the modification and flight testing of two B-52 aircraft fitted with Rolls-Royce F130 engines and associated subsystems. Program work will be carried out across multiple US locations, including Oklahoma City, San Antonio, Seattle, and Indianapolis, with completion expected by May 31, 2033. Initial funding of $35.8 million has been released, with additional allocations planned starting in fiscal year 2026 under research, development, test, and evaluation funding lines. The re-engining effort supports the broader conversion of 76 B-52H Stratofortress bombers to the B-52J standard, ensuring the platform remains operational through 2050. Replacing legacy Pratt & Whitney TF33 engines, the F130 engines provide improved fuel efficiency, reduced maintenance costs, enhanced electrical power generation, and modern digital engine controls. The upgrade also enables integration of new avionics, sensors, and weapons, including the AN/APQ-188 AESA radar, significantly improving situational awareness, targeting accuracy, and survivability in contested environments.
