Lockheed Shipbuilding and Construction Company—commonly referred to as Lockheed Shipbuilding—operated as a shipyard located in Seattle, Washington. Its operations were divided between two sites: Yard 1 on Harbor Island and Yard 2 situated at the present-day location of Jack Block Park within Seattle Terminal 5. Both yards were positioned at the entrance to the West Waterway of the Duwamish River. Established in 1898 as the Puget Sound Bridge and Dredging Company, Yard 1 was responsible for constructing Harbor Island and later became part of Lockheed in 1959. Yard 2 commenced shipbuilding activities in 1943, primarily serving the United States Navy. The shipyard ceased all operations in 1988; subsequently, Yard 2 was transferred to the Port of Seattle in 1989, followed by Yard 1 in 1997.
