US Navy’s John Lewis-class oilers to be powered by Rolls-Royce generators

Rolls-Royce announced that it has signed a contract to supply diesel generators, propellers and shaft lines for the U.S. Navy’s new fleet replenishment oiler ships, the John Lewis-class.

With a total of 17 ships to be built, the new John Lewis class (previously known as TAO – X) is designed to increase the US Navy’s capability to transfer fuel to its surface ships, in operations around the globe.

For each ship, Rolls-Royce will supply two Kamewa 150A controllable pitch propellers (CPP), whilst two Bergen B32:40xL8A generator sets will provide power to satisfy on board energy requirements.

Don Roussinos, Rolls-Royce, President – Naval, said: “This contract renews our long-standing relationship with General Dynamics’ NASSCO shipyard in San Diego, where construction of the first vessel will commence next year. 

“Rolls-Royce controllable pitch propellers, produced at our facility in Walpole Massachusetts, have been powering the US Navy fleet for many years, and we’re delighted that the John Lewis Class will continue this for decades to come.”

Each ship will have capacity to carry 156,000 barrels of fuel oil and provide significant dry cargo capacity, aviation capability and will operate at speeds of up to 20 knots.

Rolls-Royce said the contract covers the first ship, with options for five more, in a project which plans to see 17 new ships built at the rate of one per year. Equipment for the lead ship is scheduled for delivery in 2018.
