The Department of the Air Force has awarded a $2,604,329,361 contract to Rolls-Royce Corporation, Indianapolis, Indiana, for B-52H Stratofortress military derivative commercial engines.
The competitive single award contract provides for 608 military derivative commercial engines, plus spare engines, associated support equipment and commercial engineering data, to include sustainment activities, to be used on the B-52H bomber fleet.
The Rolls-Royce F130 engine will replace the TF33-PW-103, which has powered the B-52 since the 1960s, and is projected to no longer be supportable beyond 2030. The B-52 original equipment manufacturer, Boeing, is responsible for integrating the engines onto the aircraft. The Air Force plans to finalize integration activities and deliver the first lot of B-52H modified aircraft by the end of 2028.
“The B-52 CERP is a complex upgrade that not only updates the aircraft with new engines, but updates the flight deck area, struts and nacelles,” said Brig. Gen. John Newberry, Air Force bombers program executive officer.
“Our current virtual digital prototyping efforts are giving us an opportunity to integrate the engines and other changes to the B-52 before doing any physical modifications. This has allowed us to develop the most cost-efficient solution while reducing the time from concept to production.”
The B-52H is a long-range, heavy bomber that can perform strategic attack, close-air support, air interdiction, offensive counter-air and maritime operations. The bomber is capable of flying at high subsonic speeds at altitudes up to 50,000 feet. It can carry nuclear or precision guided conventional ordinance with worldwide precision navigation capability.
The new engines on the B-52s are expected to remain on the B-52H through at least 2050, increase fuel efficiency, increase range, reduce emissions in unburned hydrocarbons, and significantly reduce maintenance costs.
“The B-52 Commercial Engine Replacement Program is the most important and comprehensive upgrade to the B-52 in over half a century,” said Maj. Gen. Jason Armagost, director of Strategic Plans, Programs and Requirements at Headquarters Air Force Global Strike Command, Barksdale Air Force Base, Louisiana. “The B-52 is the workhorse of the nation’s bomber force and this modification will allow the B-52 to continue its critical conventional and standoff mission into 2050’s.”
The first two fully modified B-52s are projected to deliver by the end of 2025 and will undergo ground and flight testing. The first lot of operational B-52s with the new engines is projected to deliver by the end of 2028 with the entire fleet modified by 2035.
