Rolls-Royce has completed a $1 billion upgrade to its manufacturing, assembly, and test center in Indiana. The company has modernized the manufacturing capability at its Indianapolis campus, as well as expanded test capabilities, including a new altitude test facility at the nearby West Lafayette site.

The main focus of what has been a decade-long investment program is to enhance Rolls-Royce propulsion contributions to key defense platforms, including the BR725-derivative turbofan being developed for the U.S. Air Force’s re-engined B-52 bomber and the AE 1107F turboshaft for the U.S. Army’s Bell MV-75 Cheyenne II tiltrotor. The company also makes engines for the current V-22 Osprey tiltrotor, as well as the U.S. Navy’s MQ-25 Stingray drone and the C-130J transport aircraft.
