At the Navy Fuel Pier, Pt. Loma.
The USS Paul F. Foster (DD-964) was decommissioned on 27 March 2003. In 2004, Paul F. Foster was designated as a Self Defense Test Ship (SDTS) for the Navy, a role she assumed in 2005. In support of this new role, the now ex-Paul F. Foster was assigned to Naval Surface Warfare Center, Port Hueneme Division. She is the only Spruance class Destroyer that exists as of 2018, as all of her sister ships were either scrapped or sunk as targets upon decommissioning.
