The Iowa class battleships are the largest displacement class battleships in the United States Navy. Four Iowa class battleships have been completed, making them the longest, most powerful, fastest (reaching 33 knots), and latest decommissioned battleships in the world. Four ships of the same type are still preserved. Due to the cancellation of the Montana class, the successor ship to the Iowa class, this battleship became the last class of battleships in the United States Navy. On September 2, 1945, the signing ceremony of Japan's unconditional surrender, which marked the end of World War II, was held on the main deck of the USS Missouri anchored in Tokyo Bay, making the ship famous worldwide.
