Why The B-52's New Rolls-Royce Engines Will Make America's 70-Year-Old Bomber More Efficient Than Ever

Rolls-Royce has completed its first phase of work on replacing the B-52’s engines, marking a significant step forward in modernizing this iconic aircraft. This project will replace all 68 General Electric F110 turbofan engines with new Rolls-Royce AL35 series engines. These advanced engines are expected to significantly improve fuel efficiency for the bomber. The upgrade aims to extend the B-52's operational life and enhance its capabilities. Officials estimate that the upgraded bombers will be more efficient than ever before.
