The Lorain, Ohio Yard served as the main facility of the company after World War II and to this day five of the 13 separate 1,000 ft (300 m) ore carriers on the Great Lakes were built in Lorain, including the M/V Paul R. Tregurtha which is the largest vessel on the Great Lakes (1,013'06" long). Built in 1898, the Lorain Yard quickly grew in size and importance. The facilities eventually included two dry docks over 1,000 feet (300 m) long built to handle the largest of the Great Lakes ore carriers. The Lorain Yard closed in 1984 after a series of labor disputes. Most of the buildings associated with shipyard were demolished with only the water tower and Ship Building Pattern Warehouse remaining. The pattern warehouse is now The Shipyards dining and events venue. The remaining lands are now being redeveloped as an upscale housing development.

The Toledo Shipbuilding Company, which became an operating unit of the American Shipbuilding Company by consolidation in 1945,[6] was itself the builder of several of the most well-known coal-fired steamships of the Great Lakes, such as the SS Chief Wawatam (built in 1911).
Steinbrenners
In the early 1960s, the American Ship Building Company acquired Kinsman Marine Transit Company, which was owned by the Steinbrenner family. As a result of the transaction, the Steinbrenner family acquired a controlling interest in American Ship Building. Frustrated after years of fighting with unions over cost-saving work changes, the Steinbrenners closed the Lorain shipyard in December 1983 and moved all operations to Tampa, Florida. The principal member of the Steinbrenner family who was involved in the operation of the company at this time was George Steinbrenner, who by then already was becoming better known as the principal owner of the New York Yankees.
The company began having difficulties in the 1980s, going through a bankruptcy in 1993. The company was sold in 1995.
