Naval Ship Yards

*U.S. NAVAL SHIPYARDS AND BASES*
Since the nation's earliest days, the U.S. Navy has operated its own shipyards. There were 13 in total, four of which are still active. In addition, eight naval stations - one in the U.S., seven overseas - had some shipbuilding capability. At the end of WWII, the Navy terminated or cancelled almost all new ship construction contracts and only a few new ships were built in the Naval Shipyards thereafter. Then, in 1972, a report was published that demonstrated that ships built in Naval Shipyards cost, on average, about 30% more than ships built by private-sector shipbuilders: as a result, all new ship construction in the Naval Shipyards ceased and five of the nine remaining yards were closed. Finally, the U.S. Coast Guard maintains its own yard in Baltimore MD: a host of boats have been built there over the years but it is now primarily a maintenance facility.
