The United States Navy has awarded Rolls-Royce a contract worth $1.2 billion to support V-22 Osprey engines.

The Rolls-Royce T406 engines (company designation AE 1107C-Liberty) are housed in wing-tip tilting nacelles, allowing the distinctive flight characteristics of the V-22.

According to a contract notice:

“Rolls-Royce was awarded a $1.21B firm-fixed-price, indefinite-delivery/indefinite-quantity contract. This contract provides sustainment support of the V-22 AE1107C engine at various V-22 aircraft production, test and operating sites. Sustainment support includes program management, integrated logistics support, sustaining engineering, maintenance, repair, reliability improvements, configuration management and site support.

Work will be performed in Indianapolis, Indiana, and various locations within and outside the continental U.S., and is expected to be completed in February 2025.

No funds will be obligated at the time of award. Funds will be obligated on individual orders as they are issued. This contract was not competitively procured pursuant to 10 U.S. Code 2304. The Naval Air Systems Command is the contracting activity.”

The AE 1107C two-shaft axial design consists of a 14-stage compressor followed by an effusion-cooled annular combustor, a two-stage gas generator turbine and two-stage power turbine.

Great award!



I’m surprised the Germans haven’t restarted the Dornier Do 31 program, what with almost 50 years of technological advancements in flight tech would see (in my eyes) something to really rival the V22


Blimey that looks like a crash waiting to happen…sort of like a high wire act without a net…the fascination is in an “OMG will they die” factor.


We should re-start the Farley Rotodyne as well. That would be great for carrier on board delivery Etc


Totally agree, the concept is aerodynamically superior to the both the tilt-rotor, tandem rotor, main rotor/tail rotor combination and the co-axial helicopters for combining heavy lift and speed. Shame, Leonardo who now own the IPR, having bought out Westlands, have not done anything with the concept.


Are we in the market for these bad boys…..
