The Patapsco class of gasoline tankers were a class of tankers built for the United States Navy during World War II. The class consisted of 23 tankers, designated AOG-1 through AOG-11, and AOG-48 to AOG-59. They served through the Korean War and several served in foreign navies.
Many were built as Maritime Commission type T1-MT-M1 tanker hull, under a Maritime Commission contract, at Cargill, Inc., Savage, Minnesota.[1]
Four 980shp Cleveland Diesel Engine Division 12-278A diesel-electric engines, single main reduction gears, two propellers, for a total 3300shp.
Various ships in the class served from World War II through the Vietnam War in various campaigns. Some were transferred to the Greek Navy and Taiwan. The last ones in U.S. service were decommissioned in July 1975.[2] Taiwan decommissioned the last one, ROCS Chang Pei (AOG-517), in 2005.[3]
