USS Zumwalt

Rolls-Royce has delivered twin fixed pitch propellers manufactured for installation on the US Navy’s surface combatant, the future USS Zumwalt, to General Dynamics Bath Iron Works.

The new development marks the completion of the power and propulsion system delivery from Rolls-Royce.

Rolls-Royce Naval president Don Roussinos said: "The delivery and installation of these highly engineered propellers is a real milestone in the build of this amazing ship, as the navy will now be able to commence further systems testing, followed by sea trials in the near future."

The company has already delivered the two MT30 main turbine generator sets (MTGs) and two RR4500 auxiliary turbine generator sets (ATGs), offering a total of 78MW for total ship power.

Weighing nearly 60,000lb apiece, the NAVSEA-designed propellers were cast and machined at the Rolls-Royce facility in Pascagoula, Mississippi.

"The delivery and installation of these highly engineered propellers is a real milestone."

USS Zumwalt, the first Zumwalt-class multi-mission vessel (DDG-1000), is developed to offer independent forward presence and deterrence, support special operations forces, and an integral part of joint and combined expeditionary crew.

It also provides offensive, distributed, and precision firing capabilities for forces onshore.

Capable of accommodating a crew of 149, the 610ft-long ship has a displacement capacity of 15,620t and can support operations of two MH-60R aircraft or one MH-60R aircraft and one VTUAS.

In addition to providing independent forward presence and deterrence for carrying out operations in the littorals, the multi-mission DDG 1000 will be the first US Navy surface combatant to use electric power for propulsion and combat technology.
