"Service Above Self"

The USS Philadelphia (SSN 690) is the third Los Angeles Class attack submarine and the first 688-class submarine to be built and delivered to the U.S. Navy by the Electric Boat Division of General Dynamics Corporation, Groton, CT. Initial construction of the Philadelphia was actually delayed to prevent it being completed prior to the USS Los Angeles (SSN 688), the ship whose name the class bears. The USS Philadelphia was decommissioned June 25, 2010 in Groton, CT on her 33rd birthday.
The Nuclear-Powered Submarine Recycling Program is responsible for the dismantling and disposal of decommissioned nuclear-powered submarines. All nuclear-powered submarine dismantling is done at the Puget Sound Naval Shipyard in Bremerton, WA. Prior to commencing the inactivation availability, the submarine is placed in a stand down status. This availability consists of defueling the nuclear reactor(s), de-energizing and draining ships systems, and removing any equipment needed for reuse in the fleet. Decommissioning and striking from the Naval Vessel Register takes place after defueling is completed. The removed nuclear fuel is sent to the facilities at Arco, ID, for reprocessing. When a ship receives a official completion date, that is the date the ship in question ceases to exist as an entity. No completion date has been set for the USS Philadelphia.
