The Iowa-class battleships were a class of fast battleships built for the United States Navy during World War II. They were designed to engage enemy ships and provide naval gunfire support. The class included four ships: USS Iowa, USS New Jersey, USS Missouri, and USS Wisconsin. Each ship was equipped with nine 16-inch guns and had a top speed of over 30 knots, making them some of the fastest battleships ever built. These battleships played significant roles in various conflicts, including World War II and the Korean War. They were known for their heavy armor and advanced radar systems, which enhanced their combat effectiveness. The Iowa-class battleships were decommissioned in the 1990s, but some have been preserved as museum ships, allowing the public to learn about their history and significance in naval warfare.
