Kaiser method -- revolution in shipbuilding

During WW2, hundreds of cargo ships raced across the Atlantic in an effort to keep Britain supplied. But these ships were being sunk by German U-boats, warships and aircraft. In 1940 alone, over a thousand allied ships were lost and Britain was as risk of being cut off from much needed supplies.

The United States, while not yet at war, was playing a vital role in supplying Britain. But with ships being sunk daily, Britain and America desperately needed a way to keep all that material moving across the Atlantic. In response, 18 shipyards across the coastal United States mobilized to build thousands of large cargo ships known as Liberty Ships. They would be built even faster than the enemy could sink them. At one point the shipyards were building one large Liberty Ship every eight hours.

Two revolutionary changes in shipbuilding will make this enormous feat possible. The first is welding and the second is the use of a modular assembly process. By mid 1941, the sheer number Liberties out at sea, along with increasing armed escorts overwhelmed German forces. Advances in anti-submarine technologies also started stamping out the U-boat threat.

Today, there are only three Liberty Ships remaining of the 2,710 built that remind us of their enormous contribution to winning World War Two.

The Liberty ship was a class of cargo ship built in the United States during World War II. Though British in conception, the design was adapted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the now iconic Liberty ship came to symbolize U.S. wartime industrial output.
The class was developed to meet British orders for transports to replace those torpedoed by German U-boats. The vessels were purchased both for the U.S. fleet and lend-lease deliveries of war materiel to Britain and the Soviet Union. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945, easily the largest number of ships produced to a single design.

Their production mirrored on a much larger scale the manufacture of the Hog Islander and similar standardized ship types during World War I. The immensity of the effort, the sheer number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life, all make them the subject of much continued interest.

Only three Liberty Ships are preserved, two as operational museum ships.

Henry John Kaiser (May 9, 1882 – August 24, 1967) was an American industrialist who became known as the father of modern American shipbuilding. He established the Kaiser Shipyards, which built Liberty ships during World War II, after which he formed Kaiser Aluminum and Kaiser Steel.

History of the Marinship Corporation's Sausalito shipyard wartime operations during the period 1942 to 1945. Documents construction of the dockyards, cargo ships, and the large oil tanker ships built for the allied war efforts.

Five Liberty ships had been launched from Marinship by the first anniversary of the declaration of war. The Liberty ship, designed as an "emergency" type cargo ship, was 441 feet (134 m) long and 56 feet (17 m) abeam. President Roosevelt nicknamed them his "ugly ducklings." After 15 Liberty ships were launched at Marinship, the shipyard was retooled to produce the larger T2-SE-A2 tankers, which were 523.5 feet (159.6 m) long, and 68 feet (21 m) abeam. On 16 June 1945, Marinship set a world record by constructing and delivering the tanker SS Huntington Hills in a mere 33 days, with 28 days on the way and 5 days of fitting out after launch. At its peak, 20,000 workers were employed at Marinship. In the 3½ years that Marinship was active, it launched 15 Liberty ships, 16 fleet oilers, and 62 tankers — a total of 93 ships.

Constructing A Pre-Fabricated Ship - 1942

Shows the step-by-step construction of a pre-fabricated ship, the SS Robert E. Peary Liberty class naval cargo ship at Permanente Metals Corporation No. 2 Yard in Richmond, California. Filmed during the early days of America's involvement in World War Two, this ship set a record breaking time for construction at just 4 days, 15 hours and 29 minutes after the keel was laid down. The film shows all aspects of construction, as well as detailed scenes of activities at the dockyards and the successful launching of the ship.
