For the strength of the navy, not only large weapons such as aircraft carriers, but also nuclear submarines are also very important. It operates in deep water, is difficult to spot, and can fire missiles or torpedoes at targets when the enemy is unsuspecting. However, nuclear submarines are not free to move in any sea, and the United States has had nuclear submarine accidents, causing huge casualties.
Compared with aircraft carriers, there are not many countries that can build nuclear submarines in the world, and according to public information, there are only six countries in the world that have nuclear submarines. The development of submarines has been successful as early as World War II, but because the early submarines use battery storage, so the underwater endurance is short, it is necessary to charge frequently, and the time required for charging is longer than the time spent in the water, so countries began to develop nuclear submarines. In 1946, the United States began to develop the world's first nuclear submarine, the Nautilus, which began to be launched in 1954.
The countries with the most nuclear submarines in the world today are the United States and Russia. One is an economic power, an old military power. The development path of U.S. nuclear submarines has not been smooth. After the success of the Nautilus, the United States successively built several nuclear submarines, one of which was called the "Longtail Shark" and had an accident while carrying out its mission.
The Accident on the Longtail Shark was also the world's first nuclear submarine accident, when the submarine had 129 people in the U.S. Navy and 22 nuclear bombs, and all of them sank to the bottom of the sea. The "Longtail Shark" is an attack type of nuclear submarine, with a length of 84.9 meters, a width of 9.6 meters, a displacement of 4310 tons, and a diving depth of 396 meters.
After the submarine sank in 1963, the United States attached great importance to it because it was also the first time in the world. When the "Longtail Shark" had an accident, the crew of the submarine rescue ship "Skylark" that was on the mission with them heard a loud noise, and then they could not contact the "Longtail", they realized that it was wrong, and immediately reported to the nuclear submarine fleet command, and the command also carried out search and rescue work at the first time.
The search and rescue work has been carried out for a long time, and the United States even sent the deep submersible "Quster" to the place where the accident occurred to search. According to the fragments of the submarine taken back, it can be judged that due to the local problems of the submarine, the rupture was caused by the sudden entry of water into the cabin, which caused the internal circuit and other components of the submarine to fail, resulting in damage to the circuit and unable to control, so that the "Longtail Shark" sank, and communication could not be sent.
The submarine eventually fell into a cliff at the bottom of the sea at 2600 meters, affected by strong water pressure, the 129 American troops on board were also squashed and lost their lives, and the 22 nuclear bombs on the submarine are still missing and missing, which is a huge threat to the world.
