Philadelphia Naval Shipyard (also known as Philadelphia Navy Yard), located at League Island at the confluence of the Delaware and Schuylkill Rivers in South Philadelphia, operated from 1868 until its closure in 1995. One of the nation’s largest naval shipyards, Philadelphia Naval Shipyard built and overhauled battleships, aircraft carriers, cruisers, and destroyers throughout both World Wars and the Cold War era, employing tens of thousands of workers across all shipbuilding trades. Publicly filed asbestos litigation records document the Philadelphia Naval Shipyard with direct testimony, named asbestos product records (including Dunham Bush valve documentation), internal shipyard correspondence about asbestos, and specific boiler room exposure records — establishing it as a thoroughly documented asbestos exposure venue in the national litigation record.
