Compact power...for the most demanding marine applications

The Rolls-Royce MT7 marine gas turbine features the very latest in gas turbine technology offering a proven combination of a market leading power to weight ratio and low through life costs. Delivering power of between 4 to 5MW, the MT7 is a compact power plant with excellent fuel efficiency and performance retention.

MT7 has been selected to power the US Navy's future fleet of hovercraft, known as the Ship-to-Shore Connector (SSC). Rolls-Royce will work with Textron Marine & Land Systems, an operating unit of Textron Systems, which has been selected to build the initial development craft.

MT7 is well suited to a variety of system configurations offering ship designers and builders increased flexibility in terms of propulsion system layout, and can be configured for either mechanical or electrical drive.

The MT7 shares proven common core architecture with the AE1107C-Liberty aero engine that powers the V-22 Osprey tilt-rotor aircraft.


The MT7 is a member of the successful AE family of aero engines that has accumulated over 48 million operating hours and shares proven common core architecture with the AE 1107C-Liberty aero engine that powers the unique Bell Boeing V-22 Osprey tilt-rotor aircraft.

Rolls-Royce has delivered over 4,500 AE family engines, a heritage which allows MT7 to draw upon well established methods and processes at our production facilities, and a supply chain that delivers hundreds of engines annually. A global aftermarket support network ensures availability.
