How many battleships does US have?

The ONLY US battleships sunk during WW2 were at Pearl Harbor. And all but three were salvaged and put back into service. The three US battleships sunk at Pearl Harbor, and still rest at the bottom of the sea (and Pearl Harbor) are: 1. Battleship USS Arizona 2. Battleship USS Utah (re-designated a anti-aircraft training ship & target ship) 3. Battleship USS Oklahoma (which was raised, sold for metal re-cycling, and towed towards California after the war, where it mysteriously sunk at sea between California and Hawaii).
