Alabama Shipyard

Alabama Shipyard is the modern successor to the Alabama Drydock and Shipbuilding Company, historically known as ADDSCO, a major shipbuilding and ship-repair enterprise based on Pinto Island in Mobile Bay, Alabama. The facility began operations in 1917 and became one of the most important marine-production sites in the United States during the twentieth century. Its work included constructing, repairing, converting, and maintaining commercial and military vessels, linking the Mobile area to national defense production and the wider Gulf Coast maritime economy. The yard expanded substantially during the Second World War. It built Liberty ships, tankers, and other vessels, including twenty Liberty ships and 102 T2 tankers between 1943 and 1945. Wartime demand made ADDSCO the largest employer in southern Alabama and helped transform Mobile into a major industrial and population center. At its peak during the war, the facility employed tens of thousands of people, including large numbers of African American workers and women. The yard’s scale made it central not only to American maritime production but also to the social history of the wartime South. ADDSCO’s wartime employment history also exposed the severe racial inequalities of industrial Alabama. African Americans were initially concentrated in unskilled positions while white workers held most skilled jobs. In 1943, the promotion of African American workers to welder positions prompted a violent white riot involving shipyard workers and members of the surrounding community. The violence resulted in injuries, military and police intervention, and the temporary removal of African American workers from the facility. A subsequent compromise created segregated shipways in which African Americans could perform skilled work, although segregation and unequal treatment continued for years. This history remains an important part of the company’s legacy. The American shipbuilding industry weakened after the Second World War, and ADDSCO faced declining business and labor unrest. The Mobile yard closed in the mid-1970s but later reopened. Its ship-repair subsidiary closed in 1988. The site was partly leased to Atlantic Marine in 1989 and acquired outright by that company in 1992. After a later ownership period involving an investment group, BAE Systems acquired the yard in May 2010 and operated it as BAE Systems Southeast Shipyards. BAE Systems announced in 2018 that it would close the Mobile yard after completing its remaining projects. On June 18, 2019, Alabama Shipyard became the owner of the facility and reestablished the site under its current name. The modern operation is focused primarily on marine services rather than the mass wartime shipbuilding associated with ADDSCO. It provides ship maintenance, overhaul, repair, conversion, and ship-disposal services for customers that include the United States Departments of Defense and Transportation, as well as other public and commercial clients. The yard is described in the reference material as Mobile’s largest shipyard. The Alabama Shipyard name therefore represents both a continuing industrial site and a succession of operating identities. Its significance derives from the combination of long-term maritime operations, wartime production, labor and civil-rights history, ownership changes, and its continuing role in United States vessel maintenance and conversion.

The Alabama Drydock and Shipbuilding Company, commonly abbreviated ADDSCO, began operating in Mobile, Alabama, in 1917. Its main facility was developed on Pinto Island in Mobile Bay, where the company built a large-scale industrial complex for constructing and servicing ships. During the First and Second World Wars, the yard formed part of the United States maritime-defense production system and helped establish Mobile as an important Gulf Coast industrial city. The facility reached its greatest wartime importance during the Second World War. ADDSCO produced vessels from the keel up, including Liberty ships and tankers, while also undertaking repair work. The wartime program included twenty Liberty ships and 102 T2 tankers constructed between 1943 and 1945. Because of the urgent demand for ships and marine labor, employment expanded rapidly. By the middle of the war, the yard employed many thousands of people and had become the largest employer in southern Alabama. The influx of workers contributed to Mobile’s rapid urban and economic growth, while shortages of housing and other infrastructure created serious social pressures. The wartime yard was also a site of conflict over race and employment. African American workers were hired in significant numbers, but they were initially restricted mainly to unskilled positions, while white workers occupied skilled roles such as welding. In 1943, federal fair-employment directives and pressure from civil-rights advocates contributed to the promotion of African American workers into skilled jobs. The change provoked a violent white riot in May 1943. A large group of white shipyard workers and others attacked African American workers and damaged property. More than fifty people were injured according to the supplied reference material, and state and federal authorities deployed police and National Guard forces. The company temporarily sent African American workers home, and the eventual settlement established four segregated shipways in which African Americans could hold skilled positions, although restrictions remained on advancement and supervision. The riot did not end racial discrimination at the facility. Segregated work arrangements and unequal treatment continued after the war, reflecting the broader structure of Jim Crow Alabama. The events at ADDSCO became part of the national history of wartime racial conflict in defense industries and helped energize civil-rights organizing. The yard’s wartime history consequently combines industrial achievement with a record of exclusion, protest, violence, and incomplete workplace integration. After the war, demand for American commercial shipbuilding declined. ADDSCO experienced reduced business and labor unrest, and the Mobile yard closed in the mid-1970s. It subsequently reopened, but the company’s ship-repair subsidiary closed in September 1988. A portion of the site was leased to Atlantic Marine in March 1989, and Atlantic Marine acquired the facility outright in December 1992. The investment company associated with former United States Navy Secretary John Lehman operated the yard from 2006 to 2010. BAE Systems acquired the facility in May 2010 and operated it as BAE Systems Southeast Shipyards. Under BAE Systems, the site continued as a full-service shipyard focused on maintenance, overhaul, repair, and conversion work rather than the mass production model of the Second World War. On March 1, 2018, BAE Systems announced plans to close the yard once its remaining projects were completed. The facility changed hands and identity again on June 18, 2019, when Alabama Shipyard became its owner and reestablished operations. The present Alabama Shipyard is described as a major contractor for vessel maintenance, overhaul, repair, conversion, and ship disposal. Its customers include the Departments of Defense and Transportation and other government and commercial users. The company’s current role is therefore primarily service-oriented, while the site’s historical importance rests on its earlier position as one of the largest marine-production facilities in the United States.
