USS New Hampshire BB-70
New Hampshire was to be the fourth Montana-class battleship, and was to be named in honor of the ninth state. She was assigned to the New York Navy Yard, and would have been the third ship to bear that name had she been commissioned.
The Montana-class battleships of the United States Navy were planned as successors to the Iowa class, being slower but larger, better armored, and having superior firepower. Five were approved for construction during World War II, but changes in wartime building priorities resulted in their cancellation in favor of the Essex-class aircraft carriers and Iowa class before any Montana-class keels were laid. They would have been the first U.S. battleships too wide, with a beam of 121 feet, to transit the Panama Canal, with its 110 foot wide locks.
