SS Californian was launched on 12 May 1900 at San Francisco, California, by Union Iron Works and delivered later that year to the American-Hawaiian Steamship Company of New York City. After the United States entered World War I, the United States Shipping Board acquired Californian for war service and transferred her to the U.S. Navy on 13 May 1918. The Navy commissioned her as USS Californian on 14 May 1918 with Lieutenant Commander D. Malman, USNRF, in command.
On 22 June 1918, while proceeding through the Bay of Biscay, Californian struck a naval mine. Although a gallant attempt was made to tow her to port, she sank later that day. Her crew abandoned ship in good order and was picked up by the patrol vessel USS Corsair (SP-159) without suffering any casualties.
Unlike most commercial ships commissioned into U.S. Navy service during World War I, Californian never received a naval registry identification number.
