Boeing and Rolls-Royce have begun testing F130 engines for the B-52H Stratofortress nuclear bomber. The modernisation of the strategic aircraft will allow them to remain in service until the 1950s.

Here's What We Know

The first B-52 entered service in 1955. That means the nuclear bombers could stay in service with the U.S. Air Force for 100 years. 88 aircraft are to be upgraded, including 12 bombers that are in reserve.

The new F130 engines have been developed by the American arm of the British Rolls-Royce company in Indianapolis, Indiana. They will be the last engines to be fitted to B-52s in the aircraft's 100-year history.

The contract with the U.S. Air Force provides for production of 608 engines (8 per aircraft + 42 spares). The F130 is based on the commercial BR725. This engine in the Gulfstream G650 and other civilian aircraft has already flown 30 million hours. This approach will speed up the modernisation of Boeing's nuclear-powered bombers.

The tests take place at the National Aeronautics and Space Administration (NASA) Space Center in Mississippi and will last for several months. According to Rolls-Royce, initial test results have been promising. The company added that the F130 would improve fuel efficiency, reduce the need for refueling and cut operating costs.
