The success of the recent testing, according to Rolls-Royce, helped validate the F130 engine’s dual pod configuration as well.

Summary and Key Points: The U.S. Air Force's B-52J bomber upgrade program, now equipped with Rolls-Royce F130 engines, aims to modernize the decades-old aircraft significantly.

The B-52s will be equipped with new Rolls-Royce F130 engines, built in the United States, which promise a 30 percent improvement in fuel efficiency.

Rolls-Royce intends by 2028 to be running two versions of its UltraFan demonstrator engine - one for widebodies and the other for single-aisles - with flight tests to follow by the end of the decade.

Rolls-Royce has marked the 100th test event in its Orpheus engine technology demonstrator programme, covering 20 different configurations.

Rolls-Royce's involvement in aero engines started with the Eagle from the mid-1910s, designed at the behest of the British military during WWI.
