Victory ship The Victory ship was a type of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarine s . Based on the earlier Liberty ship , but with more powerful engines , 531 Victory ships were built . VC2 design . One of the first acts of the United States War Shipping Administration upon its formation in February 1942 was to commission the design of what came to be known as the Victory class . Initially designated EC2 - S - AP1 , where EC2 = Emergency Cargo , type 2 ( Load Waterline Length between 400 and 450 feet ) , S = steam propulsion with one propeller ( EC2 - S - C1 had been the designation of the Liberty ship design ) , it was changed to VC2 - S - AP1 before the name " Victory Ship " was officially adopted on 28 April 1943 . The design was an enhancement of the Liberty ship , which had been successfully produced in extraordinary numbers . Victory ships were slightly larger than Liberty ships , at 455 feet ( 139 m ) long and 62 feet ( 19 m ) wide with 28 feet ( 7 . 6 m ) draft ( loaded ) . With a fine raked bow and a ' cruiser ' stern , to help achieve the higher speed , they had a quite different appearance from Liberty ships . To make them less vulnerable to U - boat attacks , Victory ships made 15 to 17 knots ( 28 to 31 km / h ) , 4 to 6 knots faster than the Libertys , and had longer range . The extra speed was achieved through improved engines . Rather than the Libertys ' 2 , 500 horsepower triple expansion steam engines , Victory ships were designed to use either Lentz type reciprocating steam engines , steam turbines or Diesel engines , variously putting out between 6000 and 8500 horsepower ( 4 . 5 and 6 MW ) . Most used steam turbines , which had been in short supply earlier in the war and reserved for warships . All were oil fired , but for a handful of Canadian vessels completed with both coal bunkers and oil tanks . Another improvement was electrically powered auxiliary equipment , rather than steam - driven machinery . . To prevent hull fracture that dogged some Liberty ships , the spacing between frames were widened 6 inches to 36 inches ( 914 mm ) , making the ships less stiff . The VC2 - S - AP2 , VC2 - S - AP3 , and VC2 - M - AP4 were armed with a 5 inch ( 127 mm ) stern gun for use against submarines and surface ships , and a bow - mounted 3 " / 50 caliber gun and eight 20 mm cannon for use against aircraft . These were manned by United States Navy Armed Guard personnel . The VC2 - S - AP5 " Haskell " - class attack transports were armed with the 5 inch ( 127 mm ) stern gun , one quad 40mm Bofors cannon , four dual 40mm Bofors cannon , and ten single 20mm cannon . The " Haskell " s were operated and crewed exclusively by U . S . Navy personnel . Construction . The first vessel was SS " United Victory " launched at Oregon Shipbuilding Corporation on 12 January 1944 and completed on 28 February 1944 , and had her maiden voyage a month later . American vessels frequently had a name incorporating the word " Victory " . The British and Canadians used " Fort " and " Park " respectively . After " United Victory " , the next 34 vessels were named after allied countries , the following 218 after American cities , the next 150 after educational institutions and the remainder given miscellaneous names . The AP5 type attack transports were named after United States counties , without " Victory " in their name , with the exception of , which was named after President Roosevelt ' s late personal secretary . Although initial deliveries were slow — only 15 had been delivered by May 1944 — by the end of the war 531 had been constructed . The Commission cancelled orders for a further 132 vessels , although three were completed in 1946 for the Alcoa Steamship Company , making a total built in the United States of 534 , made up of : Of the wartime construction , 414 of these were of the standard cargo variant and 117 were attack transports . Because the Atlantic battle had been won by the time that the first ships appeared , only two were sunk by U - boats . These were " Fort Bellingham " and " Fort St . Nicholas " . Three more were sunk by Japan ese Kamikaze attack in April 1945 , " Logan Victory " , " Hobbs Victory " and " Canada Victory " . Many saw postwar conversion and various uses for years afterward . The single VC2 - M - AP4 Diesel - powered " Emory Victory " operated in Alaskan waters for the Bureau of Indian Affairs as " North Star III " . AP3 types " South Bend Victory " and " Tuskegee Victory " were converted in 1957 - 58 to ocean hydrographic surveying ships USNS " Bowditch " ( T - AGS - 21 ) and " Dutton " ( T - AGS - 22 ) , respectively . " Dutton " aided in locating the lost hydrogen bomb following the 1966 Palomares B - 52 crash . Starting in 1959 , several were removed from the reserve fleet and refitted for the National Aeronautics and Space Administration . One such ship was the SS " Kingsport Victory " , which was renamed USNS " Kingsport " and converted into the world ' s first satellite communications ship . Another was the former " Haiti Victory " , which recovered the first man - made object to return from space , the nose cone of Discoverer 13 , on 11 August 1960 . was converted in 1969 - 1970 to the range instrumentation ship for downrange tracking of ballistic missile tests . Four Victory ships became fleet ballistic missile cargo ships transporting torpedoes , Poseidon missile s , packaged petroleum , and spare parts to deployed submarine tender s : In the 1960s two Victory ships were reactivated and converted to technical research ship s by the U . S . Navy with the hull type AGTR . SS " Iran Victory " became the USS " Belmont " ( AGTR - 4 ) and SS " Simmons Victory " became the USS " Liberty " ( AGTR - 5 ) . The " Liberty " was attacked and severely damaged by Israeli forces in June 1967 and subsequently decommissioned and stricken from the Naval Register . The " Belmont " was decommissioned and stricken in 1970 . " Baton Rouge Victory " was sunk in the Mekong delta by a Viet Cong mine in August 1966 and temporarily blocked the channel to Saigon . Shipyards . The Victory ship were constructed in six West Coast and one Baltimore emergency shipyard that sprang up in World War II to build Liberty , Victory , and other ships . The Victory ship was designed to be assembled by the smallest capacity crane at these shipyards . In addition to the American construction , some ships were also built in British yards , and three hundred hulls in Canadian . Status of remaining Victory ships . Three are now open for tours as museum ships : One is laid up in the National Defense Reserve Fleet . < br > One is at Sparrows Point , Maryland undergoing scrapping : Four are at Brownsville , Texas undergoing scrapping : References .
