Philadelphia Navy Yard Annex in Philadelphia, PA - Members of the Naval Foundry and Propeller Center (NFPC) celebrate the delivery of the final propulsor component for the Columbia-class lead ship, the future USS District of Columbia (SSBN 826). Collectively, NFPC poured nearly 1 million pounds of bronze and removed well over 200,000 pounds of machine chips in developing four separate parts for the lead ship project. For more than a century, NFPC has manufactured propellors and propulsors for the U.S. Navy from their location in Philadelphia, offering unique capabilities and capacity to manufacture and deliver precision machined propulsor castings for undersea superiority.
