As the B-52 power requirements grew, the design evolved into a turbojet, the JT3. Pratt & Whitney designed the J57 to have a relatively high overall pressure ratio to help improve both thrust-specific fuel consumption and specific thrust , but it was known that throttling a single high-pressure-ratio compressor would cause stability problems.
The "H" model of the B-52 was the only production variant of the heavy bomber to be fitted with turbofan engines, and is the only model remaining in United States Air Force service. It is expected to remain as a mainstay of the Air Force heavy bomber fleet until at least 2040, with options for replacing the 8 TF33 engines with more modern ...

The Stratofortress’ X-15 rocket aircraft flew pilots to unprecedented altitudes and speeds. The first winged vehicles reached speeds of Mach-1, Mach-2, Mach-3, and Mach-4, respectively. They also flew for the first time over 130,000 feet, and eventually reached more than 364,000 feet (about 100,000 meters) above the surface of the Earth. [ 4 ]

On 24 September 2021, the United States Air Force (USAF) selected the F130 (the US military designation for the BR725) for the B-52H Stratofortress Commercial Engine Replacement Program (CERP). [11] This version has 17,000 lbf (75.6 kN) thrust, similar to the existing engines ( Pratt & Whitney TF33 ).
