Rolls-Royce Delivers Twin Fixed-Pitch Propellers for US Navy’s USS Zumwalt
Rolls-Royce has completed its delivery of twin fixed-pitch propellers especially made for installation on the US Navy's surface fighter, the future USS Zumwalt, to General Dynamics Bath Iron Works. Each NAVSEA-designed propeller weighs 60,000 pounds each and were cast and machined in Pascagoula, Mississippi at the Rolls-Royce facility. The new delivery serves as the milestone of completion for the power and propulsion system delivery from the Rolls-Royce corporation. The company has already completed a delivery of two MT30 main turbine generator sets (MTGs) along with two RR4500 auxiliary turbine generator sets (ATGs). These generators combined offer a total of 78MW for total ship power.
Don Roussinos, the Naval President for Rolls-Royce stated:
"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."
USS Zumwalt is the world’s first Zumwalt-class multi-mission vessel (DDG-1000). The ship is specifically designed to provide an autonomous forward presence, deterrence, support special operations forces, and is an essential part of a combined and collective expeditionary team. The vessel also provides offensive, distributed, and accurate firing abilities for forces aground. The USS Zumwalt is 610 feet long, can hold and accommodate a crew of 149, and has a displacement capacity of 15,620 tons. In addition, it can support the operations of two MH-60R aircraft or one MH-60R aircraft and one VTUAS.
Furthermore, in addition to offering autonomous forward presence and deterrence for carrying out operations on the shores, the multi-mission DDG 1000 will be the very first US Navy surface combatant that will utilize electric power for thrust and combat technology. The lead ship and class are named in honor of former Chief of Naval Operations Admiral Elmo R. "Bud" Zumwalt Jr., who served as Chief of Naval Operations from 1970-1974.
