The B-52, America’s unkillable Cold War-era strategic bomber, just got the green light for a big upgrade.
The Air Force’s program to replace the B-52H Stratofortress’s 1960s-era engines cleared its critical design review, the service announced May 4, setting the stage for Boeing to begin modifying the first two aircraft into the B-52J configuration later this year.
The Commercial Engine Replacement Program will swap the bomber’s eight Pratt & Whitney TF33 turbofans for Rolls-Royce F130 engines on each of the 76 B-52Hs in the active fleet.
As the original TF33s from the early 1960s continue to wear down and spare parts become increasingly scarce, the Air Force says the engines will be “unsustainable” beyond 2030. The new engines offer better fuel efficiency, longer range, lower sustainment costs and additional electrical power for modern weapons and sensors.
Supposedly the new engines increase fuel efficiency by 30%, the cost savings from which will actually pay for the upgrade.
The Air Force launched CERP in 2018 and selected the F130 in 2021 after a three-way competition that also included GE Aviation and Pratt & Whitney.
The F130, built in Indianapolis, is derived from Rolls-Royce’s BR725, the engine that powers the Gulfstream G650 business jet and has accumulated more than one million flying hours since entering service in 2012.
