American submarine USS Skate ambushed Yamato 180 miles northeast of Truk. Skate detected Yamato at 27,300 yards and dove. Skate passed down the starboard beam of Yamato, turned, and at 0518 hours fired four stern torpedoes at 2,200 yards. Crew of Skate heard one explosion and a muffled explosion as one or two torpedoes hit Yamato on the starboard side near turret No. 3, ripping a hole that extended some 15 feet downwards from the top of the blister and longitudinally some 75 feet between frames 151 and 173. The upper turret magazines flooded through a small hole punched in the longitudinal bulkhead; the hole was caused by failure of the armor belt joint between the upper and lower side protection belts. The upper magazine for No. 3 turret flooded. Yamato took on about 3,000-tons of water, far more than anticipated by the designers of the side protective system. The transport mission was aborted. The follow-up depth charge attack by Yamagumo, Tanikaze, or both failed to hit Skate, which made its escape three hours later. Later, Yamamto arrived at Truk and received emergency repairs by repair ship Akashi which also prepared a damage assessment report. US Navy intercepted a message from Yamato that read "Hull damage summary resulting from torpedo attack. Details affecting armament and machinery will be submitted later. 1. Hole from frame 163 to 170. 11 meters in diameter above the 'bilge' sic and 5 1/2 meters below penetrating outer plates of 'bilge' sic." Tabular Record of Movement
