The Kaiser Shipyards were seven major shipbuilding yards located on the U.S. west coast during World War II. Kaiser ranked 20th among United States corporations in the value of wartime production contracts. The shipyards were owned by the Kaiser Shipbuilding Company, a creation of American industrialist Henry J. Kaiser, who established the shipbuilding company 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 the San Francisco Bay Area (see Richmond Shipyards). Together, these four Kaiser Shipyards produced 747 ships, including many of the famous Liberty ships and Victory ships, more than any other complex in the United States. Only one of these ships, the Red Oak Victory, survives. Kaiser also produced the Casablanca-class escort carriers.
Three shipyards were located across the Columbia River from each other at Ryan Point in Vancouver, Washington and in the St. Johns area of Portland, Oregon (Oregon Shipbuilding Corporation), and at Swan Island in Portland.
Kaiser was known for developing new methods of ship building, 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.
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.
Henry Kaiser had been building cargo ships for the Maritime Commission in the 1930s, partnering with Todd Pacific Shipyards and the Bath Iron Works. When orders for ships from the British government, already at war with Germany, allowed for growth, Kaiser established his first Richmond shipyard begun in December 1940.
In April 1941 the Maritime Commission requested an additional Kaiser yard, to be used for Liberty ship construction, and after the attack on Pearl Harbor, Kaiser started third and fourth yards, building troop transports and LSTs, respectively.
Other details 
- Kaiser set several records:
- The Oregon Shipbuilding Yards were responsible for 455 ships.
- Kaiser recruited from across the United States to work in his yards, hiring women and minorities.
- Fields Point in Providence, Rhode Island, had a shipyard temporarily run by Kaiser-Walsh when the former management ran into difficulties. The shipyard was closed and sold after the war to a Swedish shipowner who dismantled the shipyard and later erected it in the city of Uddevalla on the west coast of Sweden.
