The Philadelphia Navy Yard was the first state-owned shipyard in the United States . It was founded as a state shipyard in 1801 on the site of a previous shipyard and officially closed in 1995. She built ships for the US Navy .


The shipyard was first built in 1776 on Front Street on the southern edge of Philadelphia . In 1801 she became a state shipyard, in 1871/76 she was relocated to League Island at the confluence of the Delaware River and Schuylkill River . In the following decades, especially during the First and Second World Wars , it was expanded more and more. It was the first shipyard in the world to use floating dry docks .

In 1917 the state-owned Naval Aircraft Factory was also opened on the premises of the shipyard.

During the Second World War , the shipyard had its largest workforce with 40,000 employees. 54 warships were built and around 574 repaired. During this time, the shipyard mainly built destroyers , but also three battleships , two aircraft carriers and two other cruisers .

After the World War, the workforce was reduced to 12,000. In the 1960s, more and more orders for new ships were awarded to private shipyards. The shipyard now concentrated primarily on the repair or overhaul of warships. The last newbuilding was the USS Blue Ridge in 1970.

In 1991, the first Bush administration set up a commission to review the requirements of the US Navy after the Cold War . This came to the conclusion that the shipyard was no longer needed. The shipyard was officially closed in 1995, but some projects continued until 2003. Today it is a museum shipyard.

Today there is a large industrial park on the site.

The Philadelphia Naval Shipyard has been listed as a Historic District on the National Register of Historic Places since December 22, 1999 .
