U.S. Air Force advances B-52J upgrade as engine replacement program completes Critical Design Review milestone
The B-52J Commercial Engine Replacement Program (CERP) has passed its Critical Design Review, clearing the path toward full-scale production and installation. The CDR milestone validates the engine integration design for the Rolls-Royce F130 powerplant on the legacy bomber fleet. This upgrade is expected to extend B-52 service life well into the 2050s while significantly improving fuel efficiency and reliability. The program represents one of the most significant modernization investments in strategic bomber aviation.
