New jet engines for the ancient but venerable American B-52 bomber now being hard-stand tested!

"Testing Of Rolls-Royce F130 Engines For The B-52 Bomber Has Begun"

From theaviationist.com/ | March 1, 2023 | article by DAVID CENCIOTTI.

"Rolls-Royce has begun testing F130 engines for the United States Air Force B-52 fleet at the NASA Stennis Space Center."

"Rolls-Royce has announced it has launched F130 engine testing at the company’s outdoor test facility at the NASA Stennis Space Center in Mississippi, U.S., on Mar. 1, 2023. The RR F130 engines were selected in 2021 to replace the bomber’s Pratt & Whitney TF33-PW-103s, used on the Strato-fortress [B-52] fleet since the 1960s."

"The TF-33 engine will no longer be supportable beyond 2030, so the B-52 Commercial Engine Replacement Program was kicked off in 2018, with GE Aviation, Pratt & Whitney and Rolls-Royce competing for the contract. The winning offer from Rolls-Royce is the military version of the BR725 engine used by the Gulfstream G650 business jet and already powering both the C-37 and E-11 BACN in service with the U.S. Air Force."

If it can be done this is the way to go! Off-the-shelf already winner certified jet engines as will replace the in-use since 1960's engines currently powering the B-52 force of bombers.
