Iowa-class battleship
Videos
The Iowa class was a class of six fast battleships ordered by the United States Navy in 1939 and 1940. They were initially intended to intercept fast capital ships such as the Japanese Kongō class and also serve as the "fast wing" in a traditional battle line alongside slower battleships. The Iowa class was designed to meet the Second London Naval Treaty's "escalator clause" limit of 45,000-long-ton (45,700 t) standard displacement. Beginning in August 1942, four vessels, Iowa, New Jersey, Missouri, and Wisconsin, were completed; two more, Illinois and Kentucky, were laid down but canceled in 1945 and 1958, respectively, before completion, and both hulls were scrapped in 1958–1959.

The United States battleship retirement debate was a debate among the United States Navy, Marine Corps, Congress, and independent groups over the effectiveness of naval gunfire support (NGFS) provided by Iowa-class battleships, and whether or not an alternative should be implemented. The debate centered on the best way to provide fire support for amphibious assault and other troops near a shoreline.
