What does the class of a ship mean and what distinguishes ships by what means

The class of a ship refers to the ship divided by displacement, main equipment or propulsion mode of the same ship in the category of surface ships, submarines, auxiliary ships and other ships, and the name of the first ship represents a certain ship class. For example, a total of 62 "Los Angeles" class attack nuclear submarines have been built in the United States, the first of which is the Los Angeles, and the name of this class is the Los Angeles class.

The subsequent 61 ships were all named differently, such as the 24th ship named "San Francisco", which can be described as follows:

Ship class - nuclear submarine.

Ship type - attack nuclear submarine.

Ship class - Los Angeles class.

Ship name - USS San Francisco.

Ship number - SSN-711

The Seawolf class, which was in service after the Los Angeles class, can no longer be classified as the same level because it is more improved than the Los Angeles class in terms of **, only the Seawolf class).

Some countries do not have a ship class, only a ship type, such as China's Type 091 attack nuclear submarine is actually the 091 class.

There are a total of 10 Nimitz-class aircraft carriers, the first of which is the Nimitz, and the others are the Reagan, Lincoln, .........Wait. But the name of the first Nimitz was given as the name of this "class".

The "generation" of a ship is mainly a concept of time, and sometimes there are several classes of ships in the same "generation". But "level" and "generation" sometimes coincide.

Difference Between Supplement Generations and Grades:

France, Britain and China's "generation" is basically the "class", while the United States and Russia due to the development of many models, sometimes in the same period at the same time the development of several classes of nuclear submarines, such as the United States in 54 to 59 years of service three classes of nuclear submarines, the first boat is the famous Nautilus, the second is a completely different reactor of the Seawolf class, the third level is the Ray class, in the ** improved. So during this period, 3 classes of nuclear submarines were developed, and all 3 classes belonged to the first generation of nuclear submarines.

Legal Analysis: The main criterion for dividing ships and boats is tonnage. Submarines of less than 500 tons are boats, and submarines of more than 500 tons are called boats, but submarines are called boats regardless of their size.

Ship refers to large military vessels, such as aircraft carriers, destroyers, ships, **. Strictly defined as a military vessel of more than 500 tons, in some respects refers to a large movable ** platform. Boat originally meant a light boat, but now it generally refers to a small boat, such as a yacht, a lifeboat, etc.

There are also large ships that are customarily called boats, such as submarines, etc. But submarines, regardless of their tonnage, are customarily called boats.

Legal basis: Regulations on Domestic Ship Management Industry

Article 1 These Provisions are formulated in accordance with relevant laws and administrative regulations in order to regulate the business activities of the ship management industry, maintain the order of the ship management market, ensure the safety of water transport, and promote the healthy development of the water transport industry.

Article 2 The provisions shall apply to the domestic ship management business operation and supervision and management activities within the territory of the People's Republic of China.

For the purposes of these Regulations, the term "ship management business" refers to the following ship management services provided by ship management operators to ship owners, ship charterers and ship operators in accordance with the agreement:

1) Ship maintenance management;

2) Ship maritime management;

3) Ship overhaul and maintenance;

4) Ship trading, leasing, operation and asset management;

5) Other ship management services.

Ships are generally distinguished according to the different tasks they perform, and are usually divided into two categories: combat ships and auxiliary ships. Combat ships are ships that are specially used for combat, and generally ships will be equipped with **, which can be further divided into surface combat ships and submarines. Auxiliary ships are usually responsible for technical and logistical support tasks.

As the name suggests, surface combat ships are ships that perform surface combat missions in Lingxiang, and can be subdivided into different types of ships according to the difference in mission types, such as aircraft carriers, cruisers, frigates, battleships, destroyers, military speedboats, mine warfare ships, amphibious combat ships, etc., of which battleships have now been eliminated by the navies of various countries.

Auxiliary ships are generally equipped with special equipment corresponding to their purpose, and are usually equipped with self-defense, but most of them do not have the role of direct combat. The types of auxiliary ships can be subdivided into supply ships, transport ships, medical ships, maintenance ships, oceanographic survey ships, intelligence support ships, base service ships, etc.
