Between 13:20 and 14:15, the second and third waves of U.S. aircraft attacked, concentrating on "Yamato". During this time, "Yamato" was hit by at least eight torpedoes and up to 15 bombs. The bombs did extensive damage to the topside of the ship, including knocking out power to the gun directors and forcing the anti-aircraft guns to be individually and manually aimed and fired, greatly reducing their effectiveness. The torpedo hits—almost all on the port side—caused "Yamato" to list enough that capsizing was now an imminent danger. The water damage-control station had been destroyed by a bomb hit making it impossible to counter-flood the specially designed spaces within the ship's hull to counteract hull damage.
