LONDON, Dec. 17 (UPI) -- The Naval Air Systems Command has exercised a final option year of a contract with Rolls-Royce for the company's support of AE 1107C engines for V-22 aircraft.
The option, the fifth for the company's MissionCare services, carries a value of $57.1 million and includes repair and support services at Rolls-Royce's facilities in Indianapolis and Oakland, Calif.
"Rolls-Royce is committed to providing innovative and affordable support to our U.S. military customers," said Rolls-Royce President Paul Craig. "We are focused on keeping their aircraft flying while continually seeking new solutions that will enhance their mission capability in future."
The Bell Boeing V-22 has both vertical takeoff and landing and short takeoff and landing capabilities. It is flown by the U.S. Marine Corps and U.S. Air Force.
Rolls-Royce said it has developed modifications to the AE 1107C engine which enable it to deliver 17 percent additional power. The modifications are being implemented under the MissionCare support contract and have increased "hot and high" performance while significantly increasing time on wing.
Details of the modifications were not provided.
