The navy's establishment is usually classified according to its mission, function, size, and equipment in the naval combat formation. Taking the U.S. military's naval establishment as an example, here are some common ways to classify it:
Tasks & Features:
Aircraft carriers (CV CVN):It is mainly used to carry and use carrier-based aircraft to carry out air combat missions.
Destroyer (DD DDG):It is mainly used for anti-submarine, anti-ship and air defense tasks, with strong firepower and shipborne ** system.
Corvettes (FF FFG):It is mainly used for tasks such as escort, anti-submarine and offshore patrols, and is usually smaller than destroyers.
Submarines (SS SSN SSBN):It is mainly used for underwater combat missions and is divided into two types: attack submarines (SSN) and ballistic missile submarines (SSBNs).
Size and displacement:
Aircraft carriers:It usually has a large displacement and is equipped with a flight deck and carrier-based aircraft facilities on the flight deck in the bow and stern.
Destroyers and frigates:Depending on its displacement and combat mission, it can be divided into a number of different models and classes.
Submarine:It is also divided into nuclear-powered submarines and conventionally powered submarines according to their displacement and combat missions.
**Equipment:
Shipborne Missile System (VLS):Equipped with a vertical launch missile system, it can launch a variety of missiles, including anti-aircraft missiles, anti-ship missiles, etc.
Anti-submarine **:Equipped with anti-submarine torpedoes, sonar systems, etc. and equipment for anti-submarine warfare.
Air defense **:Equipped with shipborne anti-aircraft missile systems and naval guns, they are used to defend against enemy aircraft and missile attacks.
These classifications are usually adjusted and subdivided according to the needs and operational requirements of the naval establishment to ensure that the naval establishment can effectively perform a variety of combat missions and meet the country's national defense needs.
Depending on the country, the ** establishment of its navy is slightly different.
