United States Submarine Calendar - USSVI Submarines and the Shipyards that Built Them

Submarine Builders of the United States Navy

Since the nation's earliest days, the U.S. Navy has operated its shipyards. There were 13 in total, four of which are still active, but not all of them build or built submarines. Also, eight naval stations - one in the United States, seven overseas - had some shipbuilding capability. At the end of WWII, the Navy terminated or canceled almost all new ship construction contracts and only built a few new ships in the Naval Shipyards after that. Then, in 1972, a report was published that demonstrated that vessels 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, closing five of the nine remaining yards. Historical records indicate nineteen or so shipyards built more than 660 U.S. submarines so far commissioned over the life of the Silent Service.
