The U.S. Navy has given Rolls-Royce a $117.7 million contract modification to procure 17 AE1107C engines in support of the V-22 aircraft, according to a Pentagon.

The deal, announced Tuesday by the U.S. Department of Defense, is worth more than $35,6 million and covers produce and deliver 17 AE1107C engines.

The Rolls-Royce AE engine family has topped 70 million engine flight hours, amassing a record of dependable and efficient service across military and commercial fleets in the US and around the world.

Rolls-Royce AE engines power C-130Js, V-22s, Global Hawks and a number of military, corporate and regional aircraft. They are in service with the US Air Force, Marines, Navy, Coast Guard, NASA and multiple military and civil customers around the world.

The AE engine line began as a powerplant for the V-22 tiltrotor aircraft for the US Marine Corps and US Air Force Special Operations Command, with first flight of the V-22 in 1989. Derivatives of the engine soon found their way onto other aircraft as the power and dependable design proved adaptable. All Rolls-Royce AE engines share a common engine core, and are about 80 percent common in their manufacture.

Also noted that this modification combines purchases for the U.S. Navy ($18,8 million); and the government of Japan ($16,7 million) under the FMS program.  

Work will be performed in Indianapolis, Indiana, and is expected to be completed in May 2020.

In addition, Pentagon has contracted a joint venture of Boeing and Bell Helicopter to provide support for the V-22 platform.
