The number was doubled in 1939 and again in 1940 to 200 ships a year. Twelve ships, including three of the 2,710 Liberties built, broke in half without warning, including SS John P. Gaines,[20][21] which sank on 24 November 1943 with the loss of 10 lives. [57][citation needed] The bridges of most of these were also enclosed in the mid-1960s in accordance with a design by naval architect Ion Livas. [45][46][47][48][49] All of these ships were decommissioned and struck from the Naval Vessel Register in 1969 and 1970. Greek entrepreneurs bought 526 ships and Italians bought 98. [62], Liberty ships were built at eighteen shipyards located along the U.S. Atlantic, Pacific and Gulf coasts:[63], This article is about the U.S. WWII Liberty class naval cargo ship. [25] The first general conversions were hastily undertaken by the War Shipping Administration (WSA) so that the ships could join convoys on the way to North Africa for Operation Torch. By 1941, the steam turbine was the preferred marine steam engine because of its greater efficiency compared to earlier reciprocating compound steam engines.

Victory cargo ships are lined up at a U.S. west coast shipyard for final outfitting before they are loaded with wartime cargo. 15. Eighteen different companies eventually built the engine. Foreword. Minor revisions to the hatches and various reinforcements were applied to the Liberty ships to arrest the cracking problem. [39] Other Liberty ships lost postwar to mines include John Woolman, Calvin Coolidge, Cyrus Adler, and Lord Delaware. In wartime they are used as raiders, combat-loaded cargo ships, auxiliary cruisers, tenders, and supply ships. In January 1943 the Chief of Staff, U.S. Army, and Commander-in-Chief, U.S. Navy agreed that the formation of a joint committee to assess enemy Naval and merchant shipping losses during World War II would be desirable. with a broad range of subject interests and I hope to present some of those 20,000 pictures I have collected over the years. [43], In 1953, the Commodity Credit Corporation (CCC), began storing surplus grain in Liberty ships located in the Hudson River, James River, Olympia, and Astoria National Defense Reserve Fleet's.

Known semi-affectionately to locals as the “Monty”, the 441ft-long (134m) vessel was a US Liberty ship, a type of cargo ship used during World War II. These ships carried the bulk of all material sent overseas, and many of the men who served there. The last two were sold for scrap to Spain in 1971 and the reserve permanently shut down.[51][52]. The ship was driven further onto the reef by rough waves and 35 mph (56 km/h) winds, which collapsed the forward bow and damaged two forward holds. Those four hold ships were designated for transport of tanks and boxed aircraft. p. 234. A large number of these ships, particularly German, Japanese, and Italian ships… Shipping magnates including John Fredriksen,[32] John Theodoracopoulos,[33] Aristotle Onassis,[34] Stavros Niarchos,[34] Stavros George Livanos, the Goulandris brothers,[34] and the Andreadis, Tsavliris, Achille Lauro, Grimaldi and Bottiglieri families were known to have started their fleets by buying Liberty ships. For ships named "Liberty", see, World War II Maritime Commission ship designs, United States naval ship classes of World War II. Fifty-eight Liberty ships were lengthened by 70 feet (21 m) starting in 1958. This was planned for 8,200 tons deadweight with some 53,000 cu.ft. Auxiliary Ships 63 Anderson (DD411). USS Bonhomme Richard 42-Gun Sailing Warship. "THE SHIPS THAT BROKE HITLER’S BLOCKADE: How a crash effort by amateur shipbuilders turned out twenty-seven hundred Liberty freighters in four years", Liberty Ships built by the United States Maritime Commission in World War II, Liberty Ships and Victory Ships, America's Lifeline in War, Ships for Victory: J.A. In 1940 the British government ordered 60 Ocean-class freighters from American yards to replace war losses and boost the merchant fleet. Although greatly outgunned, the crew of Stephen Hopkins fought back, replacing the Armed Guard crew of the ship's lone 4-inch (100 mm) gun with volunteers as they fell. The troop transports are discussed below. The first Ocean-class ship, SS Ocean Vanguard, was launched on 16 August 1941. WWII liberty ship. [22] Constance Tipper of Cambridge University demonstrated that the fractures did not start in the welds themselves, but were due to low temperature embrittlement of the steel used;[23] the same steel used in riveted construction did not have this problem. The merchant marine is collectively those non-naval ships that carry cargo or passengers or provide maritime services, and the civilian crewmen and officers who sail those ships. produced in great numbers from 1941-1945, libertys are are the most produced ship design in history with over 2700 launched. She was named after the chief engineer of a United States Army freighter who had stayed below decks to shut down his engines after a 13 April 1945 explosion, an act that won him a posthumous Merchant Marine Distinguished Service Medal. The secret project, dubbed "Project Ivory Soap", provided mobile depot support for B-29 Superfortress bombers and P-51 Mustang fighters based on Guam, Iwo Jima, and Okinawa beginning in December 1944. The Liberty ships SS Samuel R. Aitken became USS Oxford, SS Robert W. Hart became USS Georgetown, SS J. Howland Gardner became USS Jamestown with the Victory ships being SS Iran Victory which became USS Belmont and SS Simmons Victory becoming USS Liberty. This isn't actually about me - I'm not very interesting - my pictures are much more so, if you have similar interests to me! [40], On December 21, 1952, the SS Quartette, a 422-foot-long (129 m) liberty ship weighing 7,198 tons, struck the eastern reef of the Pearl and Hermes atoll at a speed of 10.5 kn (19 km/h; 12 mph). Documentary Publication. libertys formed the backbone of the american convoys, and became the simle of america military production in the war. Therefore, a 140-ton[9] vertical triple expansion steam engine of obsolete design was selected to power Liberty ships because it was cheaper and easier to build in the numbers required for the Liberty ship program and because more companies could manufacture it. of refrigerated space. SS Thomas Nelson had its bow lengthened, diesel engines installed in place of the original steam engine, and movable cranes outfitted in place of the original cargo handling gear. The fight was short, and both ships were wrecks. She is anchored in the James River Reserve Fleet.[56]. The work force was newly trained — no one had previously built welded ships. 1940. [24] The predominantly welded hull construction allowed small cracks to propagate unimpeded, unlike in a hull made of separate plates riveted together. [55] SS Albert M. Boe survives as the Star of Kodiak, a landlocked cannery, in Kodiak Harbor at .mw-parser-output .geo-default,.mw-parser-output .geo-dms,.mw-parser-output .geo-dec{display:inline}.mw-parser-output .geo-nondefault,.mw-parser-output .geo-multi-punct{display:none}.mw-parser-output .longitude,.mw-parser-output .latitude{white-space:nowrap}57°47′12″N 152°24′18″W / 57.78667°N 152.40500°W / 57.78667; -152.40500. U.S. Government Printing Office. The engine — 21 feet (6.4 m) long and 19 feet (5.8 m) tall — was designed to operate at 76 rpm and propel a Liberty ship at about 11 knots (20 km/h; 13 mph). Merchant Marine. One common type of crack nucleated at the square corner of a hatch which coincided with a welded seam, both the corner and the weld acting as stress concentrators. Ordered to stop, Stephen Hopkins refused to surrender, so the heavily armed German commerce raider Stier and her tender Tannenfels with one machine gun opened fire. The term "Liberty-size cargo" for 10,000 long tons (10,200 t) may still be used in the shipping business. As you can see, at the moment railways and shipping seem to be about it, but I am a keen deltiologist (look it up!) John W. Brown has had a long career as a school ship and many internal modifications, while Jeremiah O'Brien remains largely in her original condition. It was adopted as a Merchant Marine Act design, and production awarded to a conglomerate of West Coast engineering and construction companies headed by Henry J. Kaiser known as the Six Companies. 1. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. GTS William Patterson had its bow extended and its steam engine replaced with 6 General Electric GE-14 free-piston gas generators, connected to two reversible turbines and capable of 6,000 shp total. On Dec. 7, 1941, the cargo ship SS Cynthia Olson was the first U.S. flag ship torpedoed by a Japanese submarine in World War II. Steam turbine engines required very precise manufacturing techniques and balancing and a complicated reduction gear, however, and the companies capable of manufacturing them already were committed to the large construction program for warships. Half its payload was recovered, the rest was beyond saving. Because this museum is, more or less, in situ, your visit will be as authentic to … 14. The US version was designated 'EC2-S-C1': 'EC' for Emergency Cargo, '2' for a ship between 400 and 450 feet (120 and 140 m) long (Load Waterline Length), 'S' for steam engines, and 'C1' for design C1. This was based on a pre-war design for the Dorington Court, and resulted in a general cargo ship of around 10,000 tons deadweight and a speed of 11 knots. In September 1943 strategic plans and shortage of more suitable hulls required that Liberty ships be pressed into emergency use as troop transports with about 225 eventually converted for this purpose. [41] The crew was evacuated by the SS Frontenac Victory the following day. The design was modified by the United States Maritime Commission, in part to increase conformity to American construction practices, but more importantly to make it even quicker and cheaper to build. [7], In preparation for the Normandy landings and afterward to support the rapid expansion of logistical transport ashore a modification was made to make standard Liberty vessels more suitable for mass transport of vehicles and in records are seen as "MT" for Motor Transport vessels. USS Liberty was a Belmont-class technical research ship (electronic spy ship) that was attacked by Israel Defense Forces during the 1967 Six-Day War. Amphibious, Support, & Landing Ship models from Naval Base Hobbies 718-471-5464 Suspicion fell on the shipyards, which had often used inexperienced workers and new welding techniques to produce large numbers of ships in great haste. Merchant Mariners. [4], On 27 September 1942 the SS Stephen Hopkins was the first (and only) US merchant ship to sink a German surface combatant during the war. Furthermore, the ships were frequently grossly overloaded, increasing stresses, and some of the problems occurred during or after severe storms at sea that would have placed any ship at risk. Riveted ships took several months to construct. As America entered the war, the shipbuilding yards employed women, to replace men who were enlisting in the armed forces. The wreck of SS Richard Montgomery lies off the coast of Kent with 1,500 short tons (1,400 tonnes) of explosives still on board, enough to match a very small yield nuclear weapon should they ever go off. [4] The increase in production of more suitable vessels did allow for returning the hastily converted Liberty ships to cargo-only operations by May 1944. Excluding orders to United States shipyards, 821 ships were ordered. Several designs of mass-produced petroleum tankers were also produced, the most numerous being the T2 tanker series, with about 490 built between 1942 and the end of 1945. Liberty ships were designed to carry 10,000 long tons (10,200 t) of cargo, usually one type per ship, but, during wartime, generally carried loads far exceeding this.[6]. It endured a prolonged barrage of shrapnel, machine-gun fire and bombs. Oceangoing tug. [38], As late as December 1947, Robert Dale Owen, renamed Kalliopi and sailing under the Greek flag, broke in three and sank in the northern Adriatic Sea after hitting a mine. The List of ships of World War II is an alphabetical list of major military ships of World War II. Three Victory ships (Logan, Hobbs, and Canada) were sunk during World War II, all by kamikazes during the invasion of Okinawa. Other exceptions to the naming rule were SS Stage Door Canteen, named for the USO club in New York, and SS U.S.O., named after the organization itself.[13]. [50], In 1946, Liberty ships were mothballed in the Hudson River Reserve Fleet near Tarrytown, New York. The ships initially had a poor public image due to their appearance. The Hudson River National Defense Reserve Fleet, Image: Mothball Fleet of WWII Liberty Ships in Hudson River off Jones Point 1957, Merchant Marine Distinguished Service Medal, Allied technological cooperation during World War II, "African-Americans in the U.S. In the 1940s, 17 of the Liberty Ships were named in honor of outstanding African-Americans. Minutes of the War Production Board January 20, 1942 - October 9, 1945. [4] After the Allied victory in North Africa, about 250 Libertys were engaged in transporting prisoners of war to the United States. These Victorys carried a total of 24,000 tons of ammunition (54 million pounds or 24,000 metric tons), including the majority of 81 mm mortar available in the United States.
