The U.S. Air Force issued a $2.04-billion contract to Boeing Defense Systems for continuing work on the B-52 Commercial Engine Replacement Program. That expansive project is underway to reconfigure 76 B-52H jets with more efficient engines, raising the iconic aircraft to a new standard that will extend service life and reduce maintenance, improve range and fuel economy, and introduce new digital controls and weapon systems.
Engine replacement is the final stage of the CERP effort, and the work is expected to be carried out through May 2033.
The B-52H Stratofortress is the legacy of the 1940s-era B-29 aircraft. It’s a long-range, subsonic, heavy strategic bomber capable of carrying up to 70,000 lbs. of nuclear or conventional weapons and also used for various other missions.
Each B-52 is powered by eight engines, but the current Pratt & Whitney TF33 turbofan engines are projected to become “unsustainable” by 2030. The Rolls-Royce F130 engines that will be installed are anticipated to keep the aircraft (which now have an average age of 64 years) in service until 2050.
The re-engined and updated aircraft will be known as the B-52J.
The F130 is a high-bypass turbofan engine selected by USAF in 2021 and manufactured in Indianapolis by Rolls-Royce North America.
Boeing’s work under the new contract will be carried out in Oklahoma City, San Antonio, Tex., Seattle, and Indianapolis.
