About USNS Mission Santa Ynez

SS Mission Santa Ynez was a Type T2-SE-A2 tanker built for the United States Maritime Commission during World War II. After the war she was acquired by the United States Navy as USS Mission Santa Ynez (AO-134). Later the tanker transferred to the Military Sea Transportation Service as USNS Mission Santa Ynez (T-AO-134). A Mission Buenaventura-class oiler, she was named for Mission Santa Inés located in Solvang, California. The Mission Santa Ynez, the last T-2 tanker in existence, was stored at Suisun Bay as part of the Suisun Bay Reserve Fleet from 1975 until April 2010 when a lawsuit forced the U.S. Maritime Administration (MARAD) to remove her. The tanker was transported to a ship recycling facility in Brownsville, Texas via the Panama Canal in May 2010 for scrapping by Esco Marine.
