UNION SHIPBUILDING Baltimore MD
Most recent update: August 24, 2021.
Union Shipbuilding Company was established in 1916 by the Riter-Conley Manufacturing Co. of Pittsburgh, a large industrial steel fabricator: the site was in the Fairfield section of Baltimore, on the west side of the harbor, where in 1913 Ellicott Machine Corp. had opened a yard to build dredge hulls.  Riter-Conley's President, Thomas Riter, died in 1916, however, and the business was sold to McClintic-Marshall Co., who retained ownership until WWII, when it was acquired by the US government and became part of the Bethlehem Fairfield Shipyard.
