Oregon Shipbuilding Corporation
A World War II emergency shipyard in Portland, Oregon, that built nearly 600 Liberty and Victory ships between 1941 and 1945.
Last updated August 25, 2026
Overview
Oregon Shipbuilding Corporation was a wartime shipbuilding company and emergency shipyard located along the Willamette River in the St. Johns neighborhood of North Portland, Oregon. It operated during the United States shipbuilding expansion of World War II and was one of three major Kaiser shipyards serving the Portland metropolitan area. The other two were the Swan Island Shipyard on Swan Island and the Vancouver Shipyard across the Columbia River in Vancouver, Washington. The yard was established as part of the Emergency Shipbuilding program, which expanded American industrial capacity to produce merchant vessels for wartime logistics. Oregon Shipbuilding constructed nearly 600 ships between 1941 and 1945, including Liberty ships and later Victory ships. These standardized cargo vessels were central to the movement of troops, equipment, fuel, food, and other supplies during the war. The yard's output made it an important component of the Pacific Northwest's wartime industrial network. One of the shipyard's documented vessels was the Star of Oregon, launched on September 27, 1941, during Liberty Fleet Day. The launch illustrated the speed and public visibility of the wartime shipbuilding effort, in which shipyards sought to produce large numbers of merchant ships on accelerated schedules rather than build vessels individually through traditional methods. The shipyard's expansion had consequences beyond manufacturing. Henry J. Kaiser and associated wartime development created housing and infrastructure for workers at the three Portland-area shipyards. Vanport City, Oregon, grew rapidly in connection with this labor demand and declined after the war as shipyard employment contracted. Oregon Shipbuilding therefore formed part of a broader wartime transformation of the Portland region, including major population movement, industrial employment, and the rapid construction of worker housing. Oregon Shipbuilding Corporation was not a continuing postwar commercial brand. Its operations ended after World War II, when the emergency demand for merchant ships diminished and the temporary wartime shipbuilding system was dismantled. The former St. Johns shipyard site is now occupied by Radius Recycling, formerly known as Schnitzer Steel Industries. The corporation is consequently best understood as a historically significant wartime industrial enterprise rather than an active shipbuilding company.
History
Oregon Shipbuilding Corporation was a World War II emergency shipyard situated on the Willamette River in St. Johns, North Portland. It belonged to the group of Kaiser shipyards developed in and around Portland to expand American merchant-ship production during the war. The other Portland-area facilities were the Swan Island Shipyard and the Vancouver Shipyard in Vancouver, Washington. Its role was shaped by the Emergency Shipbuilding program, which required rapid expansion of industrial capacity and the production of standardized cargo vessels at a scale that conventional prewar shipbuilding could not easily provide. Oregon Shipbuilding built Liberty ships and Victory ships, the two principal standardized merchant-ship types associated with the American wartime production program. Together, these vessels supported the movement of supplies, personnel, and equipment across the Atlantic and Pacific theaters and helped sustain Allied military operations. The yard produced nearly 600 ships from 1941 through 1945. Its production record reflected the industrial logic of the wartime shipyards: repeatable designs, specialized work processes, large labor forces, and accelerated construction schedules. The launch of the Star of Oregon on September 27, 1941, during Liberty Fleet Day, was one publicly recorded event in the yard's history and occurred near the beginning of the United States' full wartime industrial mobilization. The shipyard also contributed to a major regional social and economic transformation. The three Portland-area Kaiser yards attracted workers from across the United States, requiring the rapid creation of housing and supporting services. Henry J. Kaiser helped develop Vanport City, Oregon, to house shipyard employees and their families. Vanport's rise was closely tied to wartime shipyard employment, while the community's subsequent contraction reflected the loss of jobs after the war. Oregon Shipbuilding thus formed part of a wider wartime migration and urban-development system rather than operating as an isolated factory. The corporation's business was inherently linked to the emergency conditions of World War II. Once the conflict ended in 1945, the extraordinary requirement for new merchant ships declined, and the shipyard closed. Unlike an enduring commercial shipbuilder, Oregon Shipbuilding Corporation left its principal legacy in wartime production, the Pacific Northwest labor market, and the industrial history of Portland. The former shipyard location in St. Johns no longer operates as Oregon Shipbuilding. The site is now associated with Radius Recycling, formerly Schnitzer Steel Industries. Historical photographs and archival documentation of the facility are preserved through collections including the Oregon Shipbuilding Corporation photographic collection, circa 1942–1945, referenced by Archives West.
