The U.S. Air Force’s B-52H engine replacement program passed its critical design review. Boeing will begin modifying the first two aircraft into the B-52J configuration later this year.
The Commercial Engine Replacement Program swaps eight legacy Pratt & Whitney engines for Rolls-Royce F130 models. This modernization secures the viability of the 76-aircraft fleet for several decades.
Completing the design review finalizes engineering plans before physical modifications and testing begin. This milestone de-risks the program and provides long-term stability for Boeing’s defense portfolio.
