California Shipbuilding Corporation

California Shipbuilding Corporation built 467 Liberty and Victory ships during World War II, including "Haskell"-class attack transports. California Shipbuilding Corporation was often referred to as Calship. The "Dictionary of American Naval Fighting Ships" sometimes refers to this shipyard as California Shipbuilding Co., but Co[mpany] appears to be an error.
The Calship shipyard was created at Terminal Island in Los Angeles, California, United States as part of America's massive shipbuilding effort of World War II. W. A. Bechtel Co. was given sponsorship and executive direction of Calship. As of 1940, Los Angeles shipyards had not built a large ship in 20 years. By late 1941 though, shipbuilding had become the second largest manufacturing industry in the Los Angeles area.
Calship was created from scratch and began production of Liberty Ships in May 1941. In the early 1940s, contracts from the U.S.Department of Maritime Commission and a number of U.S. Navy contracts led to prosperity shipbuilding business in Los Angeles. The yard was located on 175 acres on the north side of Terminal Island, north of Dock Street, near present-day berths 210-213. It initially had 8 ways, and later increased this to 14. 40,000 men and women worked under the military contract to construction of 467 vessels over 5 years. The combination of these ships were known as the "Liberty Fleet". These cargo ships were designed for rapid construction with lower costs for them. Thirteen months after commencing production, the yard broke the record by delivering 15 Liberty Ships in June 1942. It delivered 111 ships in 1942, more than any other yard in the United States. In June 1943, it broke the record again by delivering 20 ships for the month, and yet again in December 1943, delivering 23 ships.
Large Navy contracts developed shipbuilding in California. As a result of that, many workers migrated to the work area. Many shipyards sprang up from San Francisco to San Diego. At the peak of shipbuilding in California were involved 282 000 persons. Shipbuilding became a highly efficient wartime industry. The building of vessels and the number of jobs in the shipbuilding peaked in mid-1943.
The Kaiser Steel plant in Fontana, California was completed in August 1943, which enabled further production increases at Calship. Between September 27, 1941 and September 27, 1945, the yard launched 467 ships.
The Calship yard was known as "the city built on invisible stilts." It was situated on marshy ground, and was built on artificial earth supported by 57,000 piles driven into the mud. Shipbuilding commenced before the fitting-out docks were even completed. The yard's workers came from every region of the United States, reaching a force of 40,000 men and women, only 1% of whom had any shipbuilding experience whatsoever.
After the war, the Maritime Commission and the Navy department cancelled their contracts with Calship. As the result of that, the level of shipbuilding began to decline. Calship closed in September 1945, after launching the last Victory ship, "four years to the minute after the first slid into the water." Calship ranked 49th among United States corporations in the value of World War II military production contracts. 
The surviving museum ships: SS "American Victory" and SS "Lane Victory", were built in the Calship yard. The SS "American Victory" is in Tampa, Florida and the SS "Lane Victory" is in Los Angeles. They are open to the public for dockside tours and also sail periodically.
