aft of the mainmast and detonated when it hit No. 3 barbette. It failed to damage the barbette or the turret above it, but blew a hole nearly in diameter in the deck above the officer's lounge, killing 21 men and damaging four Type 96 guns on the deck above. A dud rocket of uncertain size hit the ship's fantail, but failed to do any significant damage. To convince the Americans that Nagato had been badly damaged by the attack, her damage was left unrepaired and some of her ballast tanks were pumped full of seawater to make her sit deeper in the water as if she had sunk to the harbor bottom.

By the time the war ended, Nagato was the only Japanese battleship still afloat. She was stricken from the Navy List on 15 September.
