Many Americans were unfamiliar with the name "Iowa Battleship," but if it were referred to as "Iowa-class Battleship," then many army fanatics would know it very well.
The production of this series of battleships started on July 1st, 1939. They started service on February 22nd, 1943, and served America for 50 years. It had a nickname: "Battleship of Presidents."
It got this nickname because The USS Iowa had been the flagship in 1943, as it carried President Franklin D Roosevelt across the Atlantic Ocean to meet with the British prime minister and the leaders of the Soviet Union.
"For this reason, this battleship had been specially installed with a bathtub for President Roosevelt’s use. She had become the only naval vessel in the history of the United States to have provided the President with a bathtub."
