U.S. Navy Turns To Rolls-Royce For Power

Company’s gas turbines, equipment will power hovercraft fleet

Posted on October 22, 2012

Rolls-Royce has received a contract to power the U.S. Navy’s future fleet of hovercrafts, known as the Ship-to-Shore Connector (SSC).

Each SSC will use multiple Rolls-Royce MT7 gas turbines, derived from the AE1107 engine, which powers the U.S. Marine Corps’ V-22 Osprey tilt-rotor aircraft.

The company will work with Textron Marine & Land Systems, which has been selected to build the initial development craft, in a program that could extend to 73 craft.

The SSC will replace the Navy’s current fleet of Landing Craft Air Cushion (LCAC) hovercraft over the next 20 years. The new hovercraft will be used to rapidly deploy personnel and vehicles between U.S. Navy ships and the shore.

On each hovercraft, the MT7 gas turbines will be connected to a gearbox system providing both propulsion and lift. Rolls-Royce will also design and manufacture the air intake and exhaust systems.

The MT7 is the latest Rolls-Royce gas turbine to be selected to power a major U.S. Navy program, and follows the MT30 which is already powering the Freedom class Littoral Combat Ships and will provide electrical power for the DDG-1000 Zumwalt class destroyers.
