The four battleships of the Iowa class, the crowning achievement of U.S. battleship construction, had exceptionally long careers and each in their way left a distinctive mark not only on the U.S. Navy but on naval history at large. Built as the ultimate American battleship and designed to engage the major units of the Japanese and German fleets, the vessels were commissioned in the closing stages of World War II, the beginning of half a century of service during which individual units saw action in the Korean War, the Vietnam War, the Lebanese Civil War and finally the Persian Gulf War. As such, these ships are symbolic of the primacy of U.S. seapower during the Cold War, and the preservation of all four members of this mighty class as museums is testament not only to their enduring fascination for successive generations of Americans, but also to the immense technical, financial, military, and political resources wielded by the United States during the second half of the twentieth century.
