Rolls-Royce produces the AE 1107C-Liberty engines at its manufacturing facility in Indianapolis.

Dennis Jarvi, president Defense North America for Rolls-Royce, said: “We are pleased that Rolls-Royce continues to partner with our customer to ensure the success of the V-22 Osprey Program. The AE1107C-Liberty engine was designed to provide maximum maneuverability and performance to the aircraft it powers.
