Rolls On Amphibious Craft. Rolls-Royce has been selected to provide the engines for the Navy and Marine Corps’ next generation of amphibious landing craft known as the Ship-to-Shore Connector (SSC). Rolls Royce will provide the engines for hovercrafts being built by Textron’s marine systems unit. Textron won the contract in July to build the SSCs, valued at $212.7 million for the first hovercraft. Options for eight more would bring the total value to $570.5 million. Rolls Royce said it will use it’s MT7 gas turbines engines, which are derived from the AE1107 engine that powers the V-22 Osprey tilt-rotor aircraft.
