Washington Navy Yard
By World War II, the Yard was the largest naval ordnance plant in the world. The weapons designed and built there were used in every war in which the United States fought until the 1960s. At its peak, the Yard consisted of 188 buildings on 126 acres (0.5 km²) of land and employed nearly 25,000 people. Small components for optical systems, and enormous battleship guns were all manufactured here. In December 1945, the Yard was renamed the U.S. Naval Gun Factory. Ordnance work continued for some years after World War II until finally phased out in 1961. Three years later, on July 1, 1964, the activity was re-designated the Washington Navy Yard. The deserted factory buildings began to be converted to office use. In 1963, ownership of 55 acres of the Washington Navy Yard Annex (western side of Yard including Building 170) was transferred to the General Services Administration. The Yards at the Southeast Federal Center are part of this former property and now includes the headquarters for the United States Department of Transportation.
