Bethlehem Shipbuilding San Pedro was a major shipbuilding company on Terminal Island in San Pedro, California owned by Bethlehem Shipbuilding Corporation. To support the World War 2 demand for ships Bethlehem Shipbuilding San Pedro built: US Navy Destroyers and after the war tugboats. The yard became involved in World War II production in the early shipbuilding expansions initiated by the Two-Ocean Navy Act of July 1940. At its peak during the war about 6,000 worked at the yard, Bethlehem Shipbuilding San Pedro shipyard was opened in 1918 as Southwestern Shipbuilding by Western Pipe & Steel. Western Pipe & Steel sold the shipyard to Bethlehem Shipbuilding Corporation in 1925. Shipbuilding ended after World War 2 in 1946. In 1983 the shipyard was sold to Southwest Marine. In 1997 Southwest Marine operated four shipyards, which they sold to The Carlyle Group. Carlyle Group renamed the shipyard US Marine Repair. In 2002 US Marine Repair sold all six of its yards to United Defense Industries. In 2005 it was sold to BAE Systems but the yard was not used and the yard is now part of the Port of Los Angeles. The shipyard was located at 1047 South Seaside Ave, San Pedro.

The Benson class was a class of destroyers of the U.S. Navy built 1939–1943. The thirty 1,620-ton Benson-class destroyers were built in two groups. The first six were authorized in fiscal year 1938 (FY38) and laid down at Bethlehem Steel, Quincy, Massachusetts, and three naval shipyards. The remaining 24 "repeat Bensons" were authorized in 1940–42 and built at four Bethlehem Steel yards. They were laid down after the first group was commissioned. These plus the "repeat Livermores" were also known at the time as the Bristol class. During World War II the Bensons were usually combined with the Livermores as the Benson-Livermore class; this persisted in references until at least the 1960s. In some references both classes are combined and called the Benson class. The Benson- and Gleaves-class destroyers were the backbone of the pre-war Neutrality Patrols and brought the action to the enemy by participating in every major campaign of the war.
