Naval Surface Warfare Center, Carderock Division

West Bethesda, MD and Philadelphia, PA

The Carderock Division of the Naval Surface Warfare Center (NSWCCD) is the Navy's center of excellence for ships and submarines and their systems. Work at Carderock encompasses the fields of hydrodynamics and hydromechanics, the science and technology of ship silencing and signature control, advanced electrical and mechanical systems, advanced metallic and nonmetallic materials, ship structural design and testing, ship survivability and vulnerability and shipboard environmental quality. NSWCCD employs scientists and engineers in broad disciplines such as physics, chemistry, biology, mathematics and computer science, electrical and mechanical engineering, naval architecture and much more. The Navy's problem areas in which we work are multidisciplinary and require a dynamic and innovative team approach.

With unique laboratories and test facilities, large-scale land-based engineering and test sites, and at-sea measurement facilities throughout the United States, Carderock has been at the forefront of technologies vital to the success of the Navy and the maritime industry for more than a century. The Division's primary locations are its headquarters in West Bethesda, Maryland and the Ship Systems Engineering Station in Philadelphia, Pennsylvania. NSWCCD is a major component of the Naval Sea Systems Command.

Facilities include deep-water model basins for ship hydrodynamics measurements, unmanned vehicle R&D, etc., water tunnels for propeller R&D, and other hydrodynamic and wind tunnel facilities, deep ocean pressure tanks, access to high-performance computers and modern materials science and testing laboratories.
