How to distinguish a cruiser, a frigate and a destroyer from the appearance???

In the present, the distinction between a cruiser and a destroyer is blurred, and the distinction between a destroyer and a frigate is blurred.

Surface warships with a displacement of more than 10,000 tons in the main battle of modern naval warfare are generally classified as cruisers, which are mainly used for ocean-going operations. The firepower is the strongest.

The range of destroyers is relatively large, and the large ones are ocean-going destroyers with a displacement of 8,000 to 9,000 tons, which are not much different from cruisers; There are also destroyers built in earlier years with a displacement of 3000-4000 tons for the defense of the near sea, which are even smaller than some ocean-going frigates. Destroyers are also used for a wide range of purposes, and this type of ship can fight in all sea areas and all targets. Firepower is strong.

Corvettes are generally less than 4000 tons and more than 600 tons. It is generally used for offshore operations, but there are also ocean-going frigates, which are used for defensive tasks such as anti-submarine and air defense in formation. Firepower is inferior to destroyers.

In addition, the only cruisers in the navies of various countries are the United States (27 Ticonderoga class), Russia (4 Kirov class, 1 Kara class, 1 Kenda class, 3 Glorious), Italy (1 Vittorio Veneto class), Chile (1 Dutch de Ruyter class in World War II). There are no cruisers left in other countries.

At present, destroyers and frigates are the main armament ships of all countries in the world.

The cruiser bridge is high! The main thing is to look at the tonnage.

1. Different tonnage: aircraft carriers can be divided into large aircraft carriers, medium aircraft carriers and small aircraft carriers; Most of the cruisers were in 10,000 tons; The tonnage of the destroyer is more than 1000 tons; The tonnage of the frigate is more than 500 tons.

2. The main tasks are different: aircraft carriers for carrier-based aircraft to take off and land; Cruisers were mainly active in the open ocean; Modern destroyers are equipped with air defense, anti-submarine, sea and other types; The main task of the frigate is to undertake anti-submarine, escort, patrol, alert, reconnaissance and landing support combat missions for the ship formation, as well as to provide take-off and landing of unmanned carrier-based aircraft.

3. The time of origin is different: aircraft carriers appeared in July 1917; Cruisers appeared in the 17th century; Destroyers appeared in the 90s of the 19th century; Corvettes appeared in the 16th century.

4. The nature of the aircraft carrier is different: the nature of the aircraft carrier is a comprehensive and integrated ship; Cruisers are large surface ships; Both destroyers and frigates are medium-sized combat ships.

5. Different countries where they are built: aircraft carriers are mainly built in the United States, the Soviet Union and China; CruisersIn addition to the United States and Russia, Italy and Peru each have one missile cruiser; Destroyers and frigates are being built in the United States and China.

The difference between cruisers, destroyers and frigates is that they differ in tonnage and in combat missions.

1. The tonnage is different.

Cruisers have the largest tonnage and can carry the most missiles, followed by destroyers, which are slightly inferior to cruisers, and the worst are frigates, which are often used only to defend unimportant targets.

2. The combat missions are different.

The main task of the battleship is to rely on powerful firepower to attack all ships at sea, because the battleship has the largest displacement, it can carry a number of large-caliber heavy guns, the caliber is usually more than 200 millimeters, you can imagine how powerful it is, two guns can directly scrap a ship.

The cruiser, as we can tell from its name, belongs to the ships that fight in the ocean, escort the aircraft carriers in the ocean, and are equipped with a powerful fire system as well as a defense system.

The combat function of the destroyer is relatively comprehensive; it can not only undertake the air defense and antisubmarine escort tasks of the fleet, but also undertake the tasks of patrol and vigilance and naval blockade, and is the main equipment of the modern navies of the major countries in the world.

Origin of the ship class of the frigate

The frigate is an ancient type of ship, as early as the 16th century, people called a three-masted armed sailing ship a frigate. The initial frigate had a displacement of 240 tons - 400 tons.

After the collapse of the first industrial revolution, Western countries have obtained a large number of colonies in Africa, Asia, the Americas, and Oceania, and in order to protect the security of their colonies, Western countries have built a number of small and medium-sized ships with small displacement, suitable for activities in the coastal waters of the colonies, and used for guarding, patrolling and protecting their own merchant ships, which is also one of the predecessors of frigates.

During the First World War, due to the German submarines ravaging the seas, the threat to the ships and merchant ships of the Allied countries was great, in order to protect the safety of the sea lines of communication, the Allied side began to build a large number of frigates for anti-submarine and escort.
