The Brooklyn Navy Yard (originally known as the New York Navy Yard) is a shipyard and industrial complex in northwest Brooklyn in New York City, New York, U.S. The Navy Yard is located on the East River in Wallabout Bay, a semicircular bend of the river across from Corlears Hook in Manhattan. It is bounded by Navy Street to the west, Flushing Avenue to the south, Kent Avenue to the east, and the East River on the north. The site, which covers 225.15 acres (91.11 ha), is listed on the National Register of Historic Places.
The Brooklyn Navy Yard was established in 1801. From the early 1810s through the 1960s, it was an active shipyard for the United States Navy, and was also known as the United States Naval Shipyard, Brooklyn and New York Naval Shipyard at various points in its history. The Brooklyn Navy Yard produced wooden ships for the U.S. Navy through the 1870s. The shipyard built the USS Monitor, the Navy's first ironclad warship, in 1862, and it transitioned to producing iron vessels after the American Civil War in the mid-1860s. It produced some of the Navy's last pre-dreadnought battleships just prior to World War I, and it performed major repairs and overhauls of its dreadnought and post-dreadnought battleships during World War II.
