Rolls-Royce has been awarded a two-year contract to provide aftermarket engine support for the US Marine Corps and Air Force V-22 fleets.The agreement, which is valued at up to $287m, will cover all V-22 aircraft across the Marine and Air Force fleets.The group is the sole engine provider for the aircraft.The contract provides a more than 30% reduction in support costs, which it said resulted from a significant improvement in engine time on wing since 2009 when the original MissionCare contract was signed.Tom Hartmann, Rolls-Royce's senior vice president of customer business, said: "This new contract demonstrates confidence from V-22 operators that Rolls-Royce will continue to provide outstanding service and capability to the V-22 fleets."Operators know they can count on Rolls-Royce to provide the power and support they need to succeed in their missions - while also focusing on increased affordability."
