USS Arkansas (BB-33) was a dreadnought battleship, the second member of the Wyoming class, built by the United States Navy. She was the third ship of the US Navy named in honor of the 25th state, and was built by the New York Shipbuilding Corporation. She was laid down in January 1910, launched in January 1911, and commissioned into the Navy in September 1912. Arkansas was armed with a main battery of twelve 12-inch (305 mm) guns and capable of a top speed of 20.5 knots (38.0 km/h; 23.6 mph).

Arkansas served in both World Wars. During World War I, she was part of Battleship Division Nine, which was attached to the British Grand Fleet, but she saw no action during the war. During the interwar years, Arkansas performed a variety of duties, including training cruises for midshipmen and goodwill visits overseas.

Following the outbreak of World War II, Arkansas conducted Neutrality Patrols in the Atlantic prior to America's entry into the war. Thereafter, she escorted convoys to Europe through 1944; in June, she supported the invasion of Normandy, and in August she provided gunfire support to the invasion of southern France. In 1945, she transferred to the Pacific, and bombarded Japanese positions during the invasions of Iwo Jima and Okinawa. After the end of the war, she ferried troops back to the United States as part of Operation Magic Carpet. Arkansas was expended as a target in Operation Crossroads, a pair of nuclear weapon tests at Bikini Atoll in July 1946.
