The Carderock Division of the Naval Surface Warfare Center, part of the Naval Sea Systems Command (NAVSEA), is the United States Navy’s center of excellence for ships and ship systems. It provides full spectrum research and development, test and evaluation, engineering, and Fleet support organization for the Navy’s ships, submarines, military watercraft, and unmanned vehicles. Headquartered in West Bethesda, Maryland, it has units around the nation providing vital support and services to naval operations. The Carderock Division has five technical departments. Ship Systems Integration and Design efforts focus on integrating multidisciplinary technologies and systems into total ship designs and supporting analyses for naval units. The Hydrodynamics Department researches hull forms, propulsion, and ship dynamics to provide the foundation for new ship and submarine designs. A variety of computational tools and large models operated in towing tanks, water tunnels, and sea-keeping basins are used to evaluate these new designs and concepts. The Survivability, Structures, and Materials Department focuses on the overall design and integrity of ships, as well as ship and weapon systems. The Ship Signatures Department ensures a signatures advantage for Navy surface ships, submarines, and small craft by conducting research and development in the fields of underwater acoustics, electromagnetic signatures control, and topside signatures control. The Machinery Research and Engineering Division is responsible for providing in-service engineering and test and evaluation expertise and support to various ship propulsion, electrical, and machinery systems, including auxiliary systems and submarine antenna. Captain (later Rear Admiral) David W. Taylor, USN, built the nation’s first experimental model basin for testing ship designs in 1898 at the Washington Navy Yard. Rear Admiral George W. Melville, USN, Chief of the Bureau of Engineering in the 1890s, established a naval engine testing facility in Annapolis. In 1967, the two activities were combined to form the Carderock Division. Its core competencies cover all aspects of surface ship and submarine hull, mechanical, and electrical systems and cross all life cycles, supporting naval ships from the keel to the masthead and from the cradle to the grave.
