USS Utah (AG-16) was a United States Navy target ship, the former battleship BB-31. New York Shipbuilding built her. She was launched on 23 December 1909 and commissioned on 31 August 1911.
The designation AG-16 was her later employment. The hull that had carried the battleship number BB-31 was then serving as a target ship, and that is the Utah the fleet had when the war came to Pearl Harbor.
On 7 December 1941 she was in the Attack on Pearl Harbor. Torpedoes struck the target ship and capsized her. She sank.
No one plane is credited with those torpedoes. The loss is a torpedo sinking: the blows that turned her over capsized the target ship and put her down in the course of the attack.
Utah was not raised. Capsized and sunk at Pearl Harbor, the former battleship remained where the torpedoes had left her, still the target ship AG-16 at the end of her service.
