After decades of trying, the B-52 will finally get new engines, with Rolls Royce being tapped for the contract that could be worth up to $2.6B. //

The F130 beat out General Electric's CF34-10 and Pratt and Whitney's PW800 to secure this deal. Pratt and Whitney was effectively the incumbent in this competition, though the TF33 engine that powers the B-52H now has been out of production since 1985. The company has continued to provide support for TF33s found on B-52Hs and other Air Force aircraft since then, but at an ever-growing cost. As of 2016, the Air Force was spending approximately $2 million per engine to overhaul TF33s every 6,000 flight hours. //

The TF33, which has powered the B-52H since the very first of these bombers entered service in the 1960s, is also just a dated, inefficient, low-bypass design. “Once installed, the F130 will provide vastly greater fuel efficiency while increasing range and reducing tanker aircraft requirements,” Rolls-Royce's website notes. This was another major factor for the Air Force in deciding whether or not to proceed with the re-engining effort. //

When it comes to cost, the F130 also has the benefit of being an established in-production design. F130 is the military designation for Rolls-Royce's popular BR700, thousands of examples of which power a variety of different business jets, as well as the Boeing 717 airliner. U.S. military C-37A and B aircraft — designations applied to Gulfstream V and 550s, respectively — as well as the Air Force's Bombardier BD-700-based E-11A Battlefield Airborne Communications Node (BACN) aircraft, already use versions of this engine, further simplifying maintenance and logistics chains.
