The aeroengine manufacturer will supply 268 AE 1107C engines for the Department of Defence’s V-22 Osprey aircraft.
Rolls-Royce’s president of customer business defence in North America said: “Rolls-Royce continues to be the world leader in tilt-rotor engines and this long-term contract reflects the confidence our customer has in our expertise and our technology.”
She added: “Throughout the length of this contract, we will strive to further improve performance and capability of this unique aircraft.”
In the first year of the contract Rolls-Royce will deliver 70 engines worth £94m. 268 engines are expected to be delivered in total.
Rolls-Royce’s turbo shaft engines enable the V-22 to take off and land like a helicopter, but at the same time allowing it to rotate its engines forward like an airplane. The V-22 is more efficient than a helicopter in that it flies faster, can carry more people and has a greater range of operation.
