Battleship USS Iowa is the last lead ship of any class of United States battleships.
The Iowa-class ships were a class of fast battleships ordered by the United States Navy and built in the New York, Philadelphia and Norfolk Naval Shipyards.
As its lead ship, the USS Iowa BB-61 started construction in June 1940 and finished in February 1943.
Three other Iowa class battleships are the New Jersey, the Missouri and the Wisconsin. It may be confusing with all the names of states, but the US Navy typically names great ships after states.
All four of the ships officially retired by 1992. But before that, from 1943 to 1990, the USS Iowa fought in three major U.S. wars. During World War 2, she carried President Franklin D. Roosevelt across the Atlantic to attend the Tehran Conference.
And in 1945, next to the Missouri, the Iowa also served as the Third Fleet flagship at the Japanese surrender in Tokyo Bay.
