The American submarine "Big Blue Fish" raided the Japanese aircraft carrier "DaFeng" and fired 6 torpedoes, and the Japanese pilot who had just taken off found the torpedo wake, he resolutely swooped towards the wake trajectory, and the aircraft, pilot and torpedo disappeared at the same time in the explosion. Although the pilot reacted unusually quickly and bravely, he intercepted only one torpedo and four more torpedoes passed near the stern of the carrier, but the sixth torpedo hit a particularly vulnerable part of the dafeng carrier, close to the aviation fuel tank.
The crew on the Dafeng initially had the confidence to control the damage, because the latest carrier was designed to withstand one to many torpedo strikes, and the carrier that had only one torpedo should be in no danger. But the damaged aviation fuel tank on the carrier emitted flammable gases that soon filled the entire lower deck, and an officer in the carrier's damage management team made the fatal decision to ventilate. The Air Ducts and Blowers of the Dafeng caused combustible gases to spread through the ship, a series of huge explosions tore through the ship, the armor-mounted flight deck also began to expand and eventually burst, and flames roared out of the hangar.
The Dafeng was clearly hopeless, but the captain hesitated and did not order the crew to abandon the ship, and shortly after 6 o'clock in the evening of June 19, 1944, the fiery giant ship finally sank into the sea, taking the lives of more than 1,500 crew members, and the first combat cruise of the armored aircraft carrier "Dafeng" came to an end. The "Big Blue Fish" submarine quickly dived after firing the torpedo, and although it withstood a long period of depth charge attack, it eventually escaped almost unscathed.
The sister ship of the Big BlueTail, the Spiny Fin, had been tracking the Japanese fleet and had been accurately reporting its movements for a week, and on the same day on June 19, it also got the perfect opportunity to attack the Japanese carrier "Xianghe" at close range. A few minutes before noon, the captain of the Spinfin raised his periscope and saw the Japanese carrier appearing on the nearby horizon, clearly seeing the "mattress spring" radar on the carrier, the huge sun flag, and even the faces of every crew member in the cockpit. The Spinfin fired 6 torpedoes 1,200 yards away, 3 of which hit the target, the Japanese aircraft carrier immediately began to sink from the bow, the engine compartment of the "Shozuru" was quickly submerged by the sea, the aircraft carrier was completely cut off, completely unable to move in the water, burning helplessly.
Without electricity, the firefighters of the Japanese aircraft carriers could not pressurize the fire water dragons, and they formed a bucket pass team to throw water at the flames, but to no avail. Explosions on the lower decks and hangars began to tear the carrier apart, and the captain had to order the ship to abandon. At 2:10 p.m., the ammunition depot on the carrier detonated with a deafening noise, and the huge carrier overturned to the right, the bow lifted from the water, and then the entire carrier slid into the sea, killing 1263 Japanese troops. Of the six Japanese aircraft carriers involved in the attack on Pearl Harbor, the Shōzuru was the fifth to fall into the abyss, leaving only the Tsuru carrier surviving.
After the launch of the torpedo, the "Spinfin" submarine urgently dives to avoid the inevitable attack of the depth bomb, and the sea water is poured into the submarine's main intake system, leaving it in a dangerously overweight state, and the submarine dives to a depth of more than 100 feet above the test depth. In nearly three hours of ordeal, the submarine suffered a total of 106 depth charge attacks, half of which were close to them, but the Spinfin escaped, suffering only some superficial injuries. In this way, on the same day of the Mariana Naval and Air War, the two main aircraft carriers of the Japanese army were successively sunk by the US submarines, and the Japanese army that ignored the anti-submarine experienced the evil consequences, and later there was the world's largest aircraft carrier "Shinano", which was also sunk by the US submarine for the first time...
