"First Steel Shipyard: Union Iron Works
Established during the Gold Rush, Union Iron Works moved to Potrero Point in 1883 and became the first steel shipyard on the Pacific Rim Basin. They built over 350 vessels -- from passenger liners to tankers, freighters, ferries and tugboats. The yard was best known for naval warships, including 112 destroyers and 30 submarines. Purchased by Bethelem Steel in 1905, they built ships into the 1960s." (
