Naval Warships of the past, still operating?
Got this from Wikipedia :
" The United States Navy's Naval Weapons Station Seal Beach was originally constructed during World War II for loading, unloading, and storing of ammunition for the Pacific Fleet, and especially those US Navy warships home-ported in Long Beach and San Diego, California. With closure of the Concord Naval Weapons Station in Northern California, it has become the primary source of munitions for a majority of the U.S. Pacific Fleet.[10]"
