USS Wisconsin an Iowa-class battleship, the second ship of the United States Navy to be named in honor of the U.S. state of Wisconsin. She was built at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania and launched on 7 December 1943 (the second anniversary of the Pearl Harbor raid), sponsored by the wife of Governor Walter Goodland of Wisconsin.
During her career, Wisconsin served in the Pacific Theater of World War II, where she shelled Japanese fortifications and screened United States aircraft carriers as they conducted air raids against enemy positions. During the Korean War, Wisconsin shelled North Korean targets in support of United Nations and South Korean ground operations, after which she was decommissioned. She was reactivated on 1 August 1986; after a modernization program, she participated in Operation Desert Storm in January and February 1991.
Wisconsin’s main battery consisted of nine 16 in (406 mm)/50 cal Mark 7 guns, which could hurl 2,700 lb (1,200 kg) armor-piercing shells some 20 mi (32 km).
Firing such a distance you might not see the other battleship because of the curvature of the earth.
But since we now know the earth is flat, that will never again be a problem.
The USS Wisconsin is docked at the Hampton Roads Naval Museum at Nauticus in downtown Norfolk. http://www.nauticus.org and https://www.history.navy.mil/museums/hrnm/index.html
