ww2dbaseThe Philadelphia Navy Shipyard in Pennsylvania, United States dated back to 1776 as the country's first naval shipyard. It officially became a US Navy site in 1801. In 1871, new facilities began to be established for the building of modern ships. In 1917, the Naval Aircraft Factory was established at the shipyard's League Island site. After WW1, the world's largest crane, weighing 3,500 tons, was installed at the Philadelphia Navy Shipyard. In 1926, Mustin Field began operations at the Naval Aircraft Factory site. The WW2-era would represent the shipyard's most productive period. During this period, it employed about 40,000 workers, launched 53 ships, and repaired 574 ships. Among the ships the yard had launched were the large and modern battleships USS New Jersey and USS Wisconsin. It also participated in the American atomic weapons research as Philip Abelson developed the liquid thermal diffusion technique for separating uranium-235 at the Naval Laboratory at the shipyard. After WW2, the shipyard's workforce dropped to 12,000. In the 1960s, ship construction began to be contracted out to private firms. In 1963, Mustin Field ceased operations. The final ship built at the Philadelphia Navy Yard would be the command ship Blue Ridge, launched in 1970. In 1991, the Base Realignment and Closure Commission recommended the shipyard's closure, and in 1995 it was formally closed. The 1,000-acre-sized land where the navy shipyard resided were transferred to the city of Philadelphia in Mar 2000. Today the site is of mixed use, with commercial and industrial tenants (including a commercial shipyard), and a small US Navy presence.

I just received a pin from the Naval yard from my cousin’s estate. My grandfather’s picture is on the front, draftsman,0360-19. I gather he worked here during the war as a draftsman. He was a church architect in Philadelphia. George E. Savage. Why did they not have names on the pins? It was in a green velvet box which seemed awfully fancy.

My submarine, USS Halfbeak SS-352, was in the Philly Yard in 1959 for overhaul and weeks later for newly broken generator shaft (had to cut open the hull to remove and replace it). She is not mentioned here.
While in for the Generator, while taking a shower onboard, my wallet was stolen by a yardbird.
Further, I saw 2 nearly completed Battle Cruisers, the USS California and I believe the other was the USS Hawaii. Both were moored very near the Main Gate. They too are not mentioned anywhere. What became of them?

I remember as a kid 5years old with a pot and spoon banging on the streets of South Philly in the early morning with the planes overhead going to land at the navy yard. What month was that? Thank you
