How defensive are submarines??? What are the advantages and disadvantages of submarines?

Basically, if you get hit, you won't survive, but you can still have a chance to escape the attack and even fight back.

Now the German Navy has a submarine-launched missile that can attack anti-submarine aircraft, which can attack anti-submarine aircraft that detect submarines.

To be precise, if you can't get out of the attack zone of enemy ships and anti-submarine aircraft in time, you can only be beaten.

The most harmful to the submarine is the depth charge dropped on the anti-submarine aircraft or **, after the bomb reaches a certain depth, the pressure water generated by the ** will sink the submarine, the defense is still relatively weak, but the attack is quite strong.

Of course, if it is discovered by other submarines, you can drop torpedoes or missiles to attack the opponent.

Discovered in World War II, he dived immediately and escaped as long as he dodged the opponent's depth charges. In modern times, it is difficult, once discovered, the other side will release anti-submarine missiles until they blast you out of the water and surrender.

The reason why the submarine has been able to develop to this day is that it has the following characteristics: it can use the cover of the water layer to carry out covert activities and carry out surprise attacks on the enemy; It has a large self-sufficiency, endurance and combat radius, can be far away from the base, and can fight independently in a longer period of time and a larger ocean area or even deep into the enemy's sea area, and has a strong assault power; It can launch missiles, torpedoes and lay mines underwater to attack sea and land targets.

The submarine supporting equipment is diverse, the technical requirements are high, and there are not many countries in the world that can develop and produce submarines on their own. Submarines have poor self-defense capabilities and lack effective means of air observation and air defense**; Underwater communication is difficult, and it is not easy to achieve two-way, timely and long-distance communication. The detection equipment has a close range of action, limited observation range, and is easily affected by the environment, making it difficult to grasp the enemy's situation. Conventional power submarines have low underwater speed, extremely limited endurance when sailing at high underwater speed, and must be in a snorkel navigation state when charging, which is easy to expose.

The self-sustaining power of conventional submarines is generally about 45 days, and the highest record of nuclear submarines can reach 90 days.

It is mainly composed of hull, control system, power plant, ** system, navigation system, detection system, communication equipment, underwater acoustic countermeasure equipment, life-saving equipment and living facilities.

A submarine is a ship that can sail both on the surface and in the water, also known as a submarine, and is one of the main types of ships in the Navy.

destroying the enemy's military, political, and economic centers; destroy transport ships and disrupt enemy sea lines of communication; attack large and medium-sized surface ships and submarines; Mine-laying, reconnaissance, rescue and repatriation of special personnel landing, etc.

The main role of submarines in combat is: to carry out nuclear attacks on strategic targets on land and destroy the enemy's military, political and economic centers; destroy transport ships and disrupt enemy sea lines of communication; attack large and medium-sized surface ships and submarines; Mine-laying, reconnaissance, rescue and repatriation of special personnel landing, etc.

Submarines are divided into attack submarines and strategic missile submarines according to their combat missions; According to power, it is divided into conventional power submarines (diesel-battery powered submarines) and nuclear submarines (nuclear-powered submarines); In terms of displacement, conventionally powered submarines include large submarines (more than 2,000 tons), medium submarines (600,2,000 tons), small submarines (100,600 tons) and pocket submarines (less than 100 tons), and nuclear-powered submarines are generally more than 3,000 tons; According to the hull structure, it is divided into double-hull submarines, half-hull submarines and single-hull submarines.

Nuclear-powered submarines mainly correspond to conventionally powered submarines, and their main feature is that they use nuclear reactors as power**, so they have strong power and can sail underwater at high speed for a long time. However, long-term high-speed underwater navigation is technically impossible for conventionally powered submarines, because conventionally powered submarines rely on diesel engines for high-speed navigation, which requires air that cannot be provided underwater; Underwater navigation relies on batteries, and even new AIP (non-air-propulsion) submarines cannot provide energy for long-term high-speed travel.

Nuclear-powered submarines are further divided into strategic missile and submarine and attack nuclear submarines.

The main task of strategic missile nuclear submarines is to carry out nuclear strikes on the enemy's strategic targets (such as cities, nuclear bases, etc.) through the strategic missiles equipped with them after the outbreak of a nuclear war.

The role of attacking nuclear submarines is more extensive, mainly torpedoes, anti-ship missiles, and cruise missiles, which can attack the enemy's convoys and transport fleets, destroy the enemy's sea lines of communication, search and strike at enemy submarines, and submarines equipped with cruise missiles can also attack the enemy's land targets, such as command centers, communication centers, artillery positions, troop assembly areas, etc.

The submarine cliff is that the salinity of the seawater in the lower layer is far less than the salinity of the seawater in the upper layer, so that the submarine advancing underwater will suddenly and quickly sink in a straight line without warning, and if the captain cannot command all the crew members in a very short period of tens or even ten seconds, and take effective measures to prevent the submarine from sinking, it will lead to the destruction of the submarine and the death of people.

The cliff on the bottom of the sea is a nightmare that submarine officers and men of all countries in the world can never get rid of, and many submarines of the United States and the Soviet Union have died on it. As long as the submarine goes to sea, a certain percentage will encounter this terrible natural phenomenon. Because the formation of submarine cliffs is completely random with meteorological and hydrological conditions, it cannot be detected in advance, and there are no instruments on the submarine that can detect it in advance.

What is an undersea cliff? Why would a submarine encounter be life-or-death?

Diving is possible to dive to great depths.

It is used for combat or scientific exploration.

Combat deep-sea exploration.

Submarine rescue.

Submarines are widely used, and a submarine is a type of ship that can dive underwater for activities and operations, also known as a submarine. Submarines mainly perform patrol, alert, blockade, anti-submarine, reconnaissance and other tasks.
