The MT7 marine gas turbine is a compact power plant that delivers 4 to 5 MW power, well suited to a variety of system configurations and offering ship designers and builders increased flexibility in terms of propulsion system layout, and can be configured for either mechanical or electrical drive.

A series of new contracts covers new ship engines, propulsion systems components, and services for multiple USN ship classes.

Rolls-Royce Defense has a series of new contracts from the U.S. Navy totaling $115.6 million, for ship engines, propulsion components, and services.

The $34.4-million engine contract is a follow-up order for 16 new, MT7 gas-turbine engines for USN Ship-to-Shore Connector Landing Craft, the LCAC 100 class air-cushioned landing craft produced by Textron Corp. that will be powered by four of the Rolls engines.

The MT7 is a variant of the Rolls-Royce AE 1107C engine that powered V-22 aircraft, produced in Indianapolis. Rolls-Royce is nearing completion of a $400-million improvement program at that plant.

The $10.9-million propulsion components contract includes production of main propulsion monobloc propellers, propeller hubs, blades, and other components. These will be produced at Rolls-Royce facilities in Walpole, Mass.

The $70.3-million services agreement covers maintenance and repair services of controllable pitch propeller (CPP) hubs and oil-distribution boxes (OD boxes) for multiple USN ship classes including DDG 51 destroyers. The components will be serviced at Rolls-Royce operations in Walpole. These services expected to be completed in 2026.

"Rolls-Royce propulsion equipment is in service around the globe on nearly all U.S. Navy ships and the new agreements reflect continued confidence from the Navy in Rolls-Royce products,” stated Leo Martins, Rolls-Royce Defense program director for U.S. Naval & Coast Guard Platforms.
