USS Brooklyn (SSN-816) will be a nuclear-powered of the United States Navy, the third Block VI attack submarine and 43rd overall of her class.
The submarine would be the fourth U.S. Navy vessel named for Brooklyn, a borough of New York City on Long Island.
Uniquely, Brooklyn was not ordered prior to her naming due to a dispute between the Navy and shipyards Huntington Ingalls Industries and General Dynamics Electric Boat over the potential cost.
Like their Block V predecessors, Block VI submarines will incorporate previously introduced modifications to the base design in addition to a Virginia Payload Module (VPM). The VPM inserts a segment into the boat's hull which adds four vertical launch tubes. Each tube allows for the carrying of seven Tomahawk strike missiles, increasing her armament to a total of 40 missiles.
