Alabama Dry Dock & Shipbuilding Company (ADDSCO) was formed in January 1917 by the merger of four existing Mobile companies, the Alabama Iron Works, the Ollinger & Bruce Dry Dock Company, the Gulf Dry Dock Co. and the Gulf City Boiler Works. It was one of the original nine WWII emergency yards, with four ways, built in 1941 with $19mm from the U.S. Maritime Commission. Its four ways were increased to twelve in the third wave of shipbuilding expansion to allow it to build T2 tankers. The labor force peaked at about 18,500, of whom about 6,000 were African-American. After the war, the yard reverted to being primarily a repairer, with only occasional forays into shipbuilding, but it was reorganized in 1980, with the new construction work assigned to Alabama Maritime Corporation, with a new sequence of hull numbers, while ship repair was done under the original company name. In 1989 it was sold to Atlantic Marine Holdings and the new construction side became Alabama Shipyard, while the repair side became Atlantic Marine Mobile. In 2006, it was sold again, to JFL Partners, LLC, and the whole yard is now called Atlantic Marine Alabama. Visit the shipyard at www.atlanticmarine.com and see it from the air on Google here.
