That would be a sight to see.

At 14:05 the cruiser
Yahagi sank, the victim of twelve bombs and seven torpedoes. At the same time a final flight of torpedo bombers attacked
Yamato from her starboard side. Her list was now such that the torpedoes—set to a depth of 6.1 m (20 ft)—impacted on the bottom of her hull. The battleship continued her inexorable roll to port.
[25] By 14:20 the power went out and her remaining 25 mm anti-aircraft guns began to drop into the sea. Three minutes later
Yamato capsized. Her main 460 mm turrets fell off, and as she rolled she created a suction that drew swimming crewmen back towards the ship. When the roll reached approximately 120° one of the two bow magazines detonated in a tremendous explosion.
[49] The resulting
mushroom cloud—over 4 miles (6.4 km) high—was seen 100 miles (160 km) away on
Kyūshū.
[50] Yamato sank rapidly, losing an estimated 3,055 of her 3,332 crew, including Vice-Admiral
Seiichi Itō, the fleet commander.
