Frigates against submarine tactics, can destroyers deal with submarines?

Are you talking about WWII tactics or modern anti-submarine tactics?

During World War II, it can be divided into two types: active and passive submarine.

The former is mainly to receive information from aerial detection, or based on the observation of a lookout, to spot submarines. Then, taking advantage of the speed, rush to the submarine's diving position, and use the Zuna to search. During this period, the frigate took a zigzag to expand the contact range, and judged the position of the opponent's submarine through the echo situation, and after the judgment was completed, it dropped depth charges (later with hedgehog guns) to blow the opponent out.

The practice of joint anti-submarine with multiple frigates was generally adopted, because the underwater self-sustaining ability of submarines was weak at that time. The two sides are competing for willpower and luck.

Passive submarine driving, generally when escorting the merchant fleet, the merchant fleet is attacked, the frigate immediately rushes to the possible position according to the torpedo track, and uses the Anna to search and drop depth charges.

Modern anti-submarine tactics are generally joint tactics.

First of all, the anti-submarine aircraft will search the sea area using magnetic anobecs and buoys, and if they find an abnormality, they will attack first and notify the frigate. Another situation is that after the frigate enters the high-threat sea area, it slows down, releases the towing sneer, listens to the noise of the seabed, and finds the target.

If a change in the position of an underwater target is detected, the frigate can be informed, and the frigate launches an anti-submarine missile (like the American Asrod) (with a range of about 40 km).

If the opposing submarine enters the range of 10 km, an anti-submarine torpedo attack is generally used.

Even closer to the use of anti-submarine rockets.

Can a submarine deal with a destroyer?

Not necessarily. It depends on what kind of submarine and what destroyer.

In general, submarines bypass destroyers.

This is due to the fact that a submarine is a purely offensive ** platform with poor defensive capabilities, so its concealment is its best defense. However, the search capabilities of destroyers are generally strong, and in particular, there is a professional "anti-submarine destroyer", which is specially built to deal with submarines.

However, modern submarines are becoming more and more powerful, and the most advanced submarines, especially attack nuclear submarines, should significantly surpass the vast majority of destroyers in actual combat power However, in terms of cost, submarines are also far superior to destroyers, and considering the concealment needs of submarines, in fact, there are still many times to bypass and go.

Submarines, of course, are capable of dealing with destroyers!

However, the premise is that the submarine must be well concealed underwater, and the destroyer's underwater sonar detector cannot detect the location of the submarine, otherwise it will take off anti-submarine *** or drop a torpedo to attack the submarine!

Submarines generally do not fight surface warships, especially destroyers, and when encountered, they usually quietly dodge and flee, not entangled with them, unless they receive a specific order from their superiors that they must attack a certain warship in a certain sea area.

The way to attack a battleship is very simple, just wait quietly in the water (usually in the deep sea below 100 meters), wait until the battleship is within the range of the torpedo, and then launch a torpedo to attack from the bottom of the sea!

Sometimes, submarines will receive instructions and parameters from satellites and launch cruise missiles from under the water (usually only at periscope depth) to attack surface warships hundreds of kilometers away.

Of course, it was to dive, release the jamming torpedo [technical term forgot], and then take the opportunity to dive into the deep sea to find the liquid seabed.

Submarine's biggest nemesis! What exactly is on board an anti-submarine aircraft to restrain a submarine? Netizen: I've seen it for a long time.

Modern submarine torpedoes have sonar self-guidance, and when avoiding torpedoes, they will also fire self-guided torpedoes in the general direction of the opponent, so as to force the opponent to cut off the torpedo line and adopt a self-guidance mode with a relatively low hit rate, so as to increase their own chances of survival. Therefore, now destroyers do not dare to force too close to submarines, and they are all ship-based *** or anti-submarine rockets attacking from a long distance.

1. Submarines or submarines are ships that can operate underwater. There are many types of submarines and different shapes, ranging from small civilian submersible probes that are fully automatic or operated by one or two people and operate for several hours, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and dive continuously for 3-6 months. According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices.

2. Destroyer (English: destroyer), is a multi-purpose destroyer, one of the important types of ships in the Navy since the 90s of the 19th century, modern destroyers are equipped with air defense, anti-submarine, sea and other types of destroyers, which can not only serve as offensive assault missions in sea boat formations, but also undertake air defense and anti-submarine escort tasks in combat formations, and can also serve as support forces in landing and anti-landing operations, serving as patrols, alerts, reconnaissance, Maritime blockade and sea rescue missions as well as providing take-off and landing of unmanned carrier-based aircraft, it is one of the medium-sized units with strong assault force in the navy team, and its main responsibilities are to escort as the core, and at the same time have reconnaissance patrol vigilance, minelaying, and attack on shore targets. The wide range of combat functions makes the destroyer the most versatile of modern sea vessels.

Representatives: Zumwalt-class destroyers, Type 055 destroyers.

Submarines attack enemy ships at sea, including enemy convoys, landing convoys, battle ship formations, and individual ships. When organizing the use of submarines to attack enemy ships at sea, it is necessary to correctly determine combat methods and organize and carry out battles on the premise of clearly defining combat tasks and seriously analyzing the situation. The basic methods of submarine forces to attack enemy ships at sea are positional guerrilla, regional safaris, and guided interceptions.

In World War II, it was generally a depth charge.

There are a lot of them in modern times.

Close-range: anti-submarine rocket.

Medium range: anti-submarine torpedoes, anti-submarine missiles (rocket-assisted torpedoes).

Long-range: anti-submarine *** (equipped with submarine exploration equipment and anti-submarine torpedoes or depth charges) has been used to attack submarines with sonar buoys and sound-guided torpedoes during World War II, the most famous example is that in 1944, the United States Navy's anti-submarine aircraft sank the Japanese I-52 submarine with sound-guided torpedoes in the Mid-Atlantic waters.

Hope it helps.

Sonar detection is used first, and after discovering the submarine, anti-submarine torpedoes, anti-submarine missiles, and depth charges can be used to attack the submarine. Anti-submarine aircraft can not only use sonar, but also detect the stagnation of nuclear submarines from the sea surface, so as to attack submarines.

In fact, the anti-missile system can be divided into two types of old looks.

1 is the ballistic missile interception system, which requires a very high technical content, because ballistic missiles usually attack at a speed of more than Mach 5, and it is very difficult to intercept, and the range of the phalanx is only 2 kilometers, which is completely impossible to intercept.

That's why the Dongfeng 21D is so strong.

2 is the cruise missile interception system [including anti-ship missiles], this technology is relatively low, the general flight speed will not exceed Mach 3, within the design index of the air defense missile, basically can be intercepted.

Anti-missile systems such as the Phalanx are just for targeting.

The radar on the ship found that there was a missile attack, and it could launch a missile to intercept it, and if the missile interception failed, it would be intercepted with artillery, and there were close defense guns, for example, the US military had a phalanx, and we also had a 730 close defense artillery system.

Missile interceptor missiles are like bullets hitting bullets, and the success rate is not very high.

Surface ships can defend against anti-ship missiles, which can be divided into soft and hard means, such as electronic jamming of the missile, so that its sensors can not effectively lock on the ship, or jamming bombs can occur to produce a false target on the water surface near the ship, in order to confuse and deceive the missile to attack the false target, and the ship itself may have to carry out some maneuvers to evade the guide. Hard kill includes the use of anti-aircraft and anti-missile missiles, rapid-fire guns, and so on to physically attack missiles.

The success of the defense against anti-ship missiles depends on many aspects, such as early warning of incoming missiles, adequate study of the performance of enemy missiles, and the use of these means by highly qualified command and combat personnel. If you are interested, you can take a look at the examples of Israeli naval battles in previous wars in the Middle East.

In short, the defense of missiles requires the comprehensive use of various means, and it is not enough to rely on a certain ** alone.
