On Wednesday, the Department of Defense announced that it has awarded Rolls-Royce Corp of Indianapolis a $9 million contract "modification" to a previously awarded firm-fixed-price contract. The contract in question  called upon Rolls to evaluate engine performance, and conduct any necessary repairs on AE1107C engines that power the U.S. Marine Corps fleet of MV-22 tiltrotor Osprey aircraft built by the Textron (TXT -9.69%) and Boeing (BA 1.51%) joint venture Bell Boeing.

The current modification of the original award hires Rolls to perform engineering services supporting an additional 5,886 flight hours on the USMC's MV-22 fleet, and is expected to run through November 2013.
