Bethlehem Steel Corporation Shipbuilding Division was created in 1905 when Bethlehem Steel Corporation acquired the San Francisco shipyard Union Iron Works in 1905. In 1917 it was incorporated as Bethlehem Shipbuilding Corporation, Limited; otherwise known as BethShip.
The Quincy yard was sold to General Dynamics Corporation in the mid 1960s, and closed in 1986. The Alameda yard was closed by Bethlehem Steel in the early 1970s, while the San Francisco facility was sold to British Aerospace in the mid 1990s and survives as BAE Systems San Francisco Ship Repair.
Bethlehem Steel ceased shipbuilding activities in 1997 in an attempt to preserve its core steel making operations.
