PHILADELPHIA, PA, August 25, 2006 - Kingsbury, Inc. is proud to report that the company has received an order to design and manufacture the main propulsion bearings for the first DDG-1000 ships. The order includes an option for five additional ship sets. The assemblies will be provided to the two main contractors on the project, Bath Iron Works (BIW) and Ingalls Shipyard (Northrup Grumman).
The scope of supply includes a fabricated steel housing that encloses the fluid film thrust bearing and a single journal bearing, plus a lubrication system for the thrust bearing. The bearing design is expected to take approximately 8 – 12 months to complete and is wholly integrated into the ship’s design process. Extensive engineering and computer modeling will be required to comply with the Navy’s shock requirements for this platform. The design also includes new features and modifications learned from experience on the previous DDG projects to improve maintenance intervals and costs.
According to the official U.S. Navy web site, “The lead ship and class [of the DDG-1000] are named in honor of former Chief of Naval Operations Admiral Elmo R. "Bud" Zumwalt Jr. Developed under the DD(X) destroyer program, ZUMWALT is the lead ship of a class of next-generation multi-mission surface combatants tailored for land attack and littoral dominance with capabilities that defeat current and projected threats and improve battle force defense.”
