A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, USS  Carl Vinson is a nuclear aircraft carrier (ship type) of the Nimitz class (ship class).

34-508: The Victory ship was a class of cargo ship produced in large numbers by American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship , were slightly larger and had more powerful steam turbine engines, giving higher speed to allow participation in high-speed convoys and make them more difficult targets for German U-boats . A total of 531 Victory ships were built in between 1944 and 1946. One of

68-551: A 5-inch (127 mm)/38 caliber stern gun for use against submarines and surface ships, and a bow-mounted 3-inch (76 mm)/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 stern gun, one quad 40 mm Bofors cannon , four dual 40 mm Bofors cannon, and ten single 20 mm cannon. The Haskell s were operated and crewed exclusively by U.S. Navy personnel. The Victory ship

102-531: A NATO reporting name . In addition, the ships of the class would have a number prefixed by a letter indicating the role of that type of vessel. For example, Project 641 had no name, though NATO referred to its members as Foxtrot-class submarines . The ship classification does not completely correspond common designation, particularly for destroyers, frigates and corvettes. Russia has its own classification system for these ships: The British Royal Navy (RN) has used several methods of naming classes. In addition to

136-623: A case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see County-class cruiser for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. Trafalgar -class submarines ' names all begin with T ( Turbulent , Tireless , Torbay ); and Ticonderoga -class cruisers are named after American battles ( Yorktown , Bunker Hill , Gettysburg , Anzio ). Ships of

170-790: 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 were of the standard cargo variant and 117 were attack transports. Because the Atlantic battle had been won by the time the first of the Victory ships appeared none were sunk by U-boats. Three were sunk by Japanese kamikaze attack in April 1945. Many Victory ships were converted to troopships to bring US soldiers home at

204-439: A traditional naming system for its ships. In addition, the ship's type and missions can be identified by the first number on the ship's three-digit hull number , which is placed on the front bows and the back of the stern. The naming convention is: Russian (and Soviet ) ship classes are formally named by the numbered project that designed them. That project sometimes, but not always, had a metaphorical name, and almost always had

238-572: 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 and Dutton , 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

272-512: The Confederate States Navy . Generally accepted by military historians and widely used in the more recent books, webpages and papers on the subject matter (most notably the releases of Osprey Publishing ), these latter-day classifications are sometimes considered "semi-official" (although they are not). Contemporary records, such as the " Official Records of the Union and Confederate Navies in

306-658: The Emergency Shipbuilding program . She was launched by the Oregon Shipbuilding Corporation on 12 January 1944, completed on 28 February 1944, and had her maiden voyage a month later. The ship's United States Maritime Commission designation was VC2-S-AP3, hull number 85. The Maritime Commission turned her over to a civilian contractor, the American President Lines , for operation until the end of hostilities. During World War II she served in

340-617: The Korean War and a 100 Victory ships served in the Vietnam War . Many were sold and became commercial cargo ships and a few commercial passenger ships . Some were laid up in the United States Navy reserve fleets and then scrapped or reused. Many saw postwar conversion and various uses for years afterward. The single VC2-M-AP4 Diesel-powered MV Emory Victory operated in Alaskan waters for

374-640: The Liberty ship design), it was changed to VC2-S-AP1 before the name "Victory Ship" was officially adopted on 28 April 1943. The ships were built under the Emergency Shipbuilding program . 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, 14 feet (4.3 m) longer at 455 feet (139 m), 6 feet (1.8 m) wider at 62 ft (19 m), and drawing one foot more at 28 feet (8.5 m) loaded.

408-751: The Pacific War , participating in the battle of Okinawa from 10 April 1945 to 19 April 1945. She used her deck guns to defend against attacking kamikaze aircraft while providing logistics support for the invasion of Okinawa . Some of the United States Navy Armed Guards were wounded when the ship was damaged on 16 April 1945, but there was no loss of life. United Victory was purchased by Furness Withy in 1946 and renamed Khedive Ismail after Isma'il Pasha . After refitting as an 8196- GRT 78-passenger cargo liner , she began service between Alexandria and New York City on 15 March 1948. She

442-564: The Weapon rather than Tomahawk class. In European navies, a class is named after the first ship commissioned regardless of when it was ordered or laid down. In some cases this has resulted in different class names being used in European and U.S. references; for example, European sources record the Colorado -class battleships of the United States Navy as the " Maryland class", as USS  Maryland

476-563: The 1960s two Victory ships were reactivated and converted to technical research ships by the U.S. Navy with the hull type AGTR. SS  Iran Victory became USS  Belmont and SS Simmons Victory became USS  Liberty . Liberty was attacked and severely damaged by Israeli forces in June 1967 and subsequently decommissioned and struck from the Naval Register . Belmont was decommissioned and stricken in 1970. Baton Rouge Victory

510-574: The War of the Rebellion " (Series 2, Volume 1, Part 1), show that the modern nomenclature was not in use at the time. The unofficial retro-applying of ship classes can occasionally lead to confusion. For example, while American works consistently adhere to the City - and Columbia -class monikers, works of British origin refer to the same classes as Cairo class and Tennessee class respectively, in compliance with

544-577: The accepted European convention, some classes have been named after a common theme in the included ships' names, e.g., Tribal-class destroyers , and some classes were implemented as an organizational tool, making traditional methods of naming inefficient. For instance, the Amphion class is also known as the A class. Most destroyer classes were known by the initial letter used in naming the vessels, e.g., V and W-class destroyers . Classification by letter also helped to conflate similar smaller classes of ships as in

578-512: The case of the A-class destroyers of 1913 whose names spread across the alphabet. Since the end of the Second World War , Royal Navy ship classes have also been known by their type number (e.g. Type 45 destroyer .) For the United States Navy , the first ship in a class to be authorized by Congress is the designated class leader and gives the name to the class, regardless of the order in which

612-648: The current convention to historical naval vessels sharing similarities, such as those of the American Civil War , where the Union Navy built several vessels in series, which can be termed "classes" as presently understood. Common examples include the Passaic -class monitor and the City-class ironclad , among many others, for the Union side, and Columbia class or Richmond class , for those ironclads in service with

646-646: The end of World War II as part of Operation Magic Carpet . A total of 97 Victory ships were converted to carry up to 1,600 soldiers. To convert the ships the cargo holds were converted to bunk beds and hammocks stacked three high for hot bunking . Mess halls and exercise places were also added. Some examples of Victory troopship are: SS  Aiken Victory , SS  Chanute Victory , SS  Cody Victory , SS  Colby Victory , SS  Cranston Victory , SS  Gustavus Victory , SS  Hagerstown Victory , SS  Maritime Victory , and SS  U.S.S.R. Victory . Some 184 Victory ships served in

680-539: 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 (120 and 140 m)), S = steam propulsion with AP1 = one aft propeller (EC2-S-C1 had been the designation of

714-598: The modern Royal Navy naming conventions. By the time the United States entered World War II, the current naming convention was in place, though it remains unclear as to exactly how and when the practice originated. Merchant ships are almost always classed by a classification society . These vessels are said to be in class when their hull, structures, machinery, and equipment conform to International Maritime Organization and MARPOL standards. Vessels out of class may be uninsurable and/or not permitted to sail by other agencies. A vessel's class may include endorsements for

748-438: 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 USS  Marvin H. McIntyre , 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

782-399: The same class may be referred to as sister ships . The name of a naval ship class is most commonly the name of the lead ship , the first ship commissioned or built of its design. However, other systems can be used without confusion or conflict. A descriptive name may be used; for example it was decided to group destroyers made to the same design as HMS Tomahawk , all named after weapons, as

816-459: The ships of that class are laid down, launched or commissioned. Due to numbering conventions, the lead ship often has the lowest hull number of its class. (During World War II , the award of construction contracts was not always congruent with completion, so several ships had higher hull numbers than later ships.) Before the 1920s, naval vessels were classified according to shared characteristics. However, naval historians and scholars retro-apply

850-440: The type of cargo such as "oil carrier", "bulk carrier", "mixed carrier" etc. It may also include class notations denoting special abilities of the vessel. Examples of this include an ice class , fire fighting capability, oil recovery capability, automated machinery space capability, or other special ability. SS United Victory The SS United Victory was the first of 531 Victory ships built during World War II under

884-651: Was 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 orbit, the nose cone of Discoverer 13 , on 11 August 1960. USS  Sherburne was converted in 1969–1970 to the range instrumentation ship USNS  Range Sentinel for downrange tracking of ballistic missile tests. Four Victory ships became fleet ballistic missile cargo ships transporting torpedoes, Poseidon missiles , packaged petroleum, and spare parts to deployed submarine tenders : In

918-417: Was SS  United Victory launched at Oregon Shipbuilding Corporation on 12 January 1944 and completed on 28 February 1944, making her maiden voyage a month later. American vessels frequently had a name incorporating the word "Victory". 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

952-487: Was achieved through more modern, efficient engines. Rather than the Libertys' 2,500 horsepower (1,900 kW) triple expansion steam engines , Victory ships were designed to use either Lentz type reciprocating steam engines (one ship only, oil fired), Diesel engines (one ship) or steam turbines (the rest, all oil fired) (variously putting out between 6,000 and 8,500 hp (4,500 and 6,300 kW)). Another improvement

986-485: Was commissioned before USS  Colorado . The West German Navy ( Bundesmarine ) used a three-digit type number for every class in service or in advanced project state. Modified versions were identified by a single letter suffix. After the reunification of Germany the German Navy ( Deutsche Marine ) kept the system. Informally, classes are also traditionally named after their lead ships. The Indonesian Navy has

1020-407: Was designed to be able to be assembled by the smallest capacity crane at these shipyards. Three are preserved as museum ships : See also, similar role:- Empire ship , Fort ship , Park ship , Ocean ship . See also, similar role:- Empire ship , Fort ship , Park ship , Ocean ship . Ship class In the course of building a class of ships, design changes might be implemented. In such

1054-436: Was electrically powered auxiliary equipment, rather than steam-driven machinery. To prevent the hull cracks that many Liberty ships developed—making some break in half—the spacing between frames was widened from 30 inches (760 mm) to 36 inches (910 mm), making the ships less stiff and more able to flex. Like Liberty ships, the hull was welded rather than riveted. The VC2-S-AP2, VC2-S-AP3, and VC2-M-AP4 were armed with

1088-536: Was noted for good proportion of cubic between holds for a cargo ship of its day. A Victory ship's cargo hold one, two and five hatches are single rigged with a capacity of 70,400, 76,700, and 69,500 bale cubic feet respectively. Victory ships hold three and four hatches are double rigged with a capacity of 136,100 and 100,300 bale cubic feet respectively. Victory ships have built-in mast , booms and derrick cranes and can load and unload their own cargo without dock side cranes or gantry if needed. The first vessel

1122-788: Was sunk in the Mekong delta by a Viet Cong mine in August 1966 and temporarily blocked the channel to Saigon . According to the War Production Board minutes in 1943, the Victory Ship had a relative cost of $ 238 per deadweight ton (10,500 deadweight tonnage ) for $ 2,522,800, equivalent to $ 35,500,000 in 2023. Most Victory ships were constructed in six West Coast and one Baltimore emergency shipyards that were set up in World War II to build Liberty, Victory, and other ships. The Victory ship

1156-407: Was up just under 1,000 tons, to 15,200. With a raised forecastle and a more sophisticated hull shape 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 (7.4 to 11.1 km/h) faster than the Libertys, and had longer range. The extra speed
