On December 7, 1941 Japanese bombers were primarily targeting the battleships at Pearl Harbor. As the linked image shows, the destroyers USS Downes and USS Cassin were both destroyed, but the battleship they shared Drydock #1 with somehow managed to come out of the battle relatively undamaged despite being a much bigger target. Identify this battleship named for an eastern state, the only battleship that was in dry dock at Pearl on that day, and which was later sunk after being a target ship as a part of the Operation Crossroads nuclear tests.
