The largest of the Navy's five systems commands, the Naval Sea Systems Command (NAVSEA) engineers build and support America's Fleet of ships and combat systems. Accounting for nearly one-fifth of the Navy's budget, NAVSEA manages more than 150 acquisition programs and has more than 53,000 civilian and military employees at 33 activities in 16 states.
NAVSEA's Warfare Center Enterprise is comprised of the Naval Surface Warfare Center (NSWC) and the Naval Undersea Warfare Center (NUWC). With eight Surface Warfare and two Undersea Warfare sites across the United States, the Warfare Centers supply the technical operations, people, technology, engineering services and products needed to equip and support the fleet and meet the warfighters' needs. The Warfare Centers are the Navy's principal research, development, test and evaluation (RTD&E) assessment activity for surface ship and submarine systems and subsystems. In addition, the Warfare Centers provide depot maintenance and in-service engineering support to ensure the systems fielded today perform consistently and reliably in the future.
