Rolls-Royce Delivers Advanced Waterjets US Navy Freedom Littoral Combat Ship

Rolls-Royce, has delivered the new and advanced Axial Mk1 waterjet for the latest Freedom-variant of the Littoral Combat Ship (LCS) class, currently under construction for the U.S. Navy. Rolls-Royce Axial Mk1 waterjets are very power dense, delivering more cavitation-freeperformance for their size and power than any other waterjet. At 22MW of power, a single waterjet of this scale can move almost half a million gallons of seawater per minute. Four of these waterjets will propel the LCS at speeds in excess of 40 knots. This delivery marks the successful completion of the Office of Naval Research's (ONR) Future Naval Capabilities (FNC) program for “Compact, High Power Density Waterjets”. This new, highly efficient waterjet will now be standard equipment for all future Freedom variants of the Littoral Combat Ships supplied to the U.S. Navy by Lockheed Martin. The delivery of these waterjets is the culmination of a successful teaming betweenindustry, ONR, the Naval Surface Warfare Center – Carderock Division, and the LCS Program Office. The new waterjets are produced in the United States, with primary manufacturing activity at Rolls-Royce facilities in Walpole, Massachusetts and Pascagoula, Mississippi. The underlying design of the Rolls-Royce Axial Mk1 waterjet has also been scaled for other research and development activity within the U.S. Navy. Last year the power dense waterjet was retrofitted on Sealion, theSpecial Operations test craft, for performance demonstration tests. Most recently, Rolls-Royce has provided the Navy's unmanned technology community with a 100mm diameter scaled design for the X-Class USV program MUSCL. Rolls-Royce manufactures a wide range of waterjets that power craft ranging from small patrol boats, to naval ships and the world's largest high speed ferries. Waterjets provide high levels of manoeuvrability and efficiency and are particularly suited to vessels operating in shallow waters.

UK MOD awards £800 million submarine propulsion contract

The UK MOD has awarded an £800 million contract to Rolls-Royce to deliver and maintain the UK's nuclear propulsion capability for submarines.
Under the 10-year contract, which will help sustain around 2,000 jobs across the UK, Rolls-Royce will deliver and maintain the nuclear power source for the Royal Navy’s Astute Class and future Successor deterrent submarines.
Part of the Submarine enterprise performance programme (SEPP), this contract will also help the company to transform its operations to carry out its work at best value for the taxpayer. By consolidating costs into one agreement, MOD and Rolls-Royce expect to make savings of around £200 million over the next decade.
This contract goes a long way towards meeting the government’s commitment to SEPP, as announced in the 2010 Strategic defence and security review, to make at least £900 million of savings by restructuring the UK’s nuclear submarine industry.
Productive negotiations between MOD and Rolls-Royce mean the savings secured by this contract will not lead to any reduction in the required level of output for the submarine programme, which includes the production of the propulsion systems for the Astute and next-generation Successor classes of submarines.
