Philadelphia Naval Shipyard

The Philadelphia Naval Shipyard has a long history, from its beginnings pre-Civil War to its decommissioning in the late 1990's.
The first government-owned navy yard in Philadelphia, the birthplace of the nation and the largest city in the young republic, was started with two docks in 1798. Workers at the yard numbered seventy thousand at its peak. The area was enlarged and shipbuilding at this site increased, notably during the War of 1812 and the Civil War. The yard's area was not dramatically increased, however, until the federal government purchased the 800-acre League Island and closed the former facility in 1868. The golden age of the Philadelphia Naval Shipyard came during World War II, when it built fifty-three ships and converted or overhauled some twelve hundred more. After the 1970s, however, shipbuilding was discontinued. The yard continued to serve its country through the modernization of existing craft, but it was closed by the government in 1990 and officially decommissioned in 1996.
