How dangerous is a submarine in the sea?

Submarines are weapons and equipment with very strong attack power. They hide silently on the bottom of the sea, waiting for their opponents to relax and launch a fatal blow. With the continuous advancement of technology, current submarines have more advanced performance and are valued by various countries as an important maritime force.

But the use of submarines is also very dangerous, and a little carelessness can lead to huge disasters. Next, we will introduce the four major causes of submarine accidents. A slight carelessness or operational error can lead to the sacrifice of hundreds of people. Among them, the United States and the Soviet Union are the most important.

The first is a violation of operating regulations. Because a submarine is a highly sophisticated piece of equipment, strict regulations must be followed at every step. In 2001, a U.S. submarine crashed into a fishing boat because it did not conduct a first reconnaissance of the sea during an emergency resurface, resulting in the deaths of nine people.

The second is improper operation of detonating weapons. A submarine is a relatively closed ship. There are many powerful weapons in the submarine, and some of them are even mobile nuclear reactors themselves. In 2000, a Russian submarine detonated a torpedo that killed 118 people.

The third is the noise impact of the ocean. Submarines cannot be seen underwater at all and can only rely on radar and sonar to move forward. However, the ocean itself has a lot of noise, so some stationary things cannot be discovered in time. A British submarine was discovered in 2015 Hit an iceberg.

The fourth is due to the influence of debris. There are often some messy things in the ocean that cannot be cleaned up, such as fishing nets and so on. Although these things are inconspicuous, they will pose a great threat to the submarine. Once they get entangled in the propeller, the submarine will lose power and become unable to move

(First, the submarine's underwater speed is not high . Especially conventional submarines. Conventional submarines can only use battery power underwater, their maximum speed is only about 20 knots, and their endurance is never less than 2 hours. Compared with the common speed of surface ships, which is 30 knots, it cannot run. , and anti-submarine helicopters, and the submarine has no chance of running away. If a submarine is discovered on the surface, it will die faster. If it directly uses anti-ship missiles or even anti-aircraft missiles to greet you, the surface speed of the submarine will not be as fast as that of the surface ship, and it will still not be able to run away. . Therefore, when a submarine is discovered on the surface, the submarine will dive urgently. Maybe others will not find it if it dives. After talking about conventional submarines, let’s talk about nuclear submarines. Nuclear submarines can maintain a speed of about 35 knots underwater. Months. However, the speed of nuclear submarines is incomparable to anti-submarine helicopters and fixed-wing anti-submarine aircraft. Submarines do not have any air defense capabilities.

Secondly, there are only three anti-submarine weapons. Types: depth bombs, anti-submarine torpedoes, anti-submarine rockets

Depth bombs: the main weapon of anti-submarine, large-yield ordinary bombs with a fixed depth controller, for example, set to explode at 100 meters, to 100 meters underwater. It explodes in just one meter. It is very cheap and easy to use. The destroyer found that it was not a problem to drop dozens of them at a time. Due to the incompressible nature of water, the explosives exploded in the water without hitting the submarine. If the explosion occurs at a distance, the submarine may be damaged. If the submarine's shell is damaged, the water pressure will be fatal. Destroyers, frigates, submarine hunters, and fixed-wing anti-submarine aircraft are all equipped with it)
