Rolls-Royce lands military contract boost

The U.S. Department of Defense has awarded a more than $15 million contract modification to Rolls-Royce Corp. in Indianapolis. The contract will support maintenance work for engines on V-22 aircraft operated by Japan’s defense forces.

The engines are Rolls-Royce AE 1107C engines that are manufactured in Indianapolis.

A spokesperson for Rolls-Royce told IIB the contract includes setting up a test cell at existing Kawasaki Heavy Industries facilities in Japan to test the engines following overhauls.

Just over a quarter of the work for the contract will be performed in Indy with the majority taking place in Hyogo, Japan. Work is expected to be complete in May 2026.

The Naval Air Systems Command in Maryland is the contracting activity.
