Wedoany.com Report-Dec.24, Boeing has received a $2 billion contract award from the U.S. Department of Defense related to the B-52 Commercial Engine Replacement Program (CERP), the Pentagon announced on December 23, 2025.

The task order, valued at approximately $2.04 billion, supports post-critical design review development activities for the program. Boeing Defense Systems will carry out system integration work, modify two B-52 aircraft with new engines, and incorporate associated subsystems for testing.

Work under the contract will take place at multiple locations, including Oklahoma City, San Antonio, Seattle, and Indianapolis. Completion is expected by May 31, 2033. Funding will be provided incrementally, beginning with $35.8 million from Fiscal 2026 research, development, test, and evaluation allocations.

The B-52 Commercial Engine Replacement Program aims to upgrade the long-serving B-52H bombers by installing modern, more efficient engines. The new engines, designated F130 by Rolls-Royce (based on its commercial BR725 design), replace the older Pratt & Whitney TF33 engines. This upgrade seeks to improve fuel efficiency, range, reliability, and overall performance while extending the aircraft's service life well into the future.

Boeing, as the original manufacturer of the B-52 Stratofortress, serves as the prime contractor responsible for integrating the new engines and related modifications. The program will result in the upgraded aircraft being designated as B-52J.

The initiative forms part of broader efforts to modernize the U.S. Air Force's strategic bomber fleet. The B-52, in service since the 1950s, continues to play a key role in national defense capabilities, with upgrades ensuring its relevance for decades ahead.

This latest award advances the program following earlier milestones, including the selection of Rolls-Royce for engine supply in 2021. The contract reflects ongoing commitment to maintaining and enhancing existing platforms through targeted improvements in propulsion technology.

The announcement highlights Boeing's continued involvement in defense aviation projects, supporting system enhancements for legacy aircraft.
