On August 8, New York Harbor was shaken by an explosion, and 1.5 million square feet of historic structures came tumbling down. The Military Ocean Terminal Bayonne (MOTBY) was originally conceived as a commercial facility, a 440-acre manmade peninsula for rail and maritime shipping. With the outbreak of World War II, the Navy took it over and completed the project, building the Navy Supply Center and an annex to the Brooklyn Navy Yard with a 1,092-foot dry dock at its point. This shipyard would allow for docking of ships that were too large to fit underneath the Brooklyn and Manhattan Bridges, and was used to remove superstructure components (antennae, stacks, etc.) that would allow ships to access the main yard in Brooklyn. After the war, Bayonne became home to the Atlantic Reserve Fleet, with dozens of mothballed ships berthed at the peninsula.
