Two private shipyards build all U.S. nuclear-powered ships.  These two shipyards, together with four public shipyards, provide the nation’s capability to overhaul, repair, refuel, and inactivate nuclear-powered ships.  These complicated tasks require an experienced and skilled workforce specifically trained to do naval nuclear propulsion work.  With approximately 50,000 employees, these six shipyards are unique industrial assets with capabilities found nowhere else in the United States.
