Summary

Kaiser Shipyards, founded by industrialist Henry J. Kaiser around 1939, was a vital organization during World War II, operating seven major shipbuilding facilities on the West Coast, including four in Richmond, California, and three in the Pacific Northwest (Portland, Oregon, and Vancouver, Washington). Renowned for its innovative and efficient shipbuilding methods, Kaiser's yards produced an impressive 1,490 ships, accounting for 27 percent of the Maritime Commission's total construction, completing vessels like Liberty ships in significantly less time and at a lower cost than other shipyards. The organization ranked 20th among U.S. corporations for wartime production contracts before ceasing operations at the end of the war. Its legacy continues through the Rosie the Riveter/World War II Home Front National Historical Park, located at a former Richmond shipyard, and its historical significance is echoed in modern proposals, such as California Forever's plan to build new West Coast shipyards to address national security and shipbuilding capacity concerns.

Kaiser Shipyards

The Kaiser Shipyards were seven major shipbuilding yards located on the West Coast of the United States during World War II. Kaiser ranked 20th among U.S. corporations in the value of wartime production contracts. The shipyards were owned by the Kaiser Company, a creation of American industrialist Henry J. Kaiser (1882–1967), who entered the shipbuilding industry around 1939 in order to help meet the construction goals set by the United States Maritime Commission for merchant shipping. Four of the Kaiser Shipyards were located in Richmond, California, and were called the Richmond Shipyards. Three other shipyards were located in the Pacific Northwest along the Columbia and Willamette rivers: the Oregon Shipbuilding Corporation and the Swan Island Shipyard in Portland, Oregon, and the Vancouver Shipyard in Vancouver, Washington. Henry Kaiser was known for developing new methods of shipbuilding, which allowed his yards to outproduce other similar facilities and build 1,490 ships, 27 percent of the total Maritime Commission construction. Kaiser's ships were completed in two-thirds the time and a quarter the cost of the average of all other shipyards. Liberty ships were typically assembled in a little over two weeks, and one in less than five days. Kaiser Shipyards shut down at the end of the war. The Rosie the Riveter/World War II Home Front National Historical Park was dedicated October 25, 2000, on the site of one of the shipyards in Richmond.
