Rolls-Royce has received a $26.5 million contract modification from Naval Air Systems Command to produce more AE1107C-Liberty engines for the V-22 Osprey.

Eight engines for the USN and four for the USAF are included in the latest contract, which followed a $72.87 million modification in February 2021.

Work will be performed in Indianapolis, Indiana, and is expected to be completed in December 2022.

According to Shephard Defence Insight, the USN and USAF have ordered about 1,000 AE1107C engines to date.

The twin-shaft axial design of the AE1107C consists of a 14-stage compressor followed by an effusion-cooled annular combustor, a two-stage gas generator turbine and a two-stage power turbine.
