Cruisers are second only to battleships in anti-ship and anti-submarine surface attack ships, with a displacement of more than 8,000 tons. Before the birth of the aircraft carrier, can lead the fleet of ships for ocean patrol and combat; after the birth of the aircraft carrier, can rely on shore-based aircraft and independently in the offshore waters, but also can be used as a carrier frigate in the ocean combat. Compared with the destroyer, the cruiser's tonnage is bigger, the endurance is stronger, and some of them also adopt the nuclear power; its attack and defense ability is also more powerful, such as the former Soviet Union's "Kirov" class cruiser, which can carry more than 500 ship - ship and ship - air missiles, each ship ship missiles loaded with more than a ton of a missile is enough to send the enemy aircraft carrier into the sea. Enemy aircraft carriers to the bottom of the sea, and the fire control system can make it hit dozens of active targets at the same time; in addition to three anti-submarine helicopters, as well as torpedoes, depth charges and a variety of other weapons, so it was crowned "Battlecruiser" of the beauty of the name. But the combat is also to pay attention to the military economic efficiency, from the economy, repairability and combat performance and other indicators on the comprehensive consideration, the destroyer may be better, so the cruiser has been gradually replaced by the trend of the destroyer.
Destroyers
Destroyers are medium-sized warships with missiles, torpedoes, and naval guns as their main weapons, and have a variety of combat capabilities. It is one of the stronger ships in the naval fleet, used to attack submarines and surface ships, fleet air defense, as well as escort, reconnaissance patrols, mines, and attacks on shore targets.
Frigate
Frigate is a missile, gun, depth charges and anti-submarine torpedoes as the main weapon of light surface combatant ships. Its main task is to carry out anti-submarine, escort, patrol, guard, reconnaissance and landing support operations for the fleet.
Replenishment ship
Ocean-going comprehensive replenishment ship is the sea formation does not rely on overseas ports for ocean voyage, the necessary protection force of long-distance sea combat
Landing ship
Landing ship
Landing ship
Landing ship used to transport landing troops and weapons and equipment. There are two kinds of large and medium-sized. Large landing craft, displacement 2000 - 8000 tons, range of 3000 nautical miles or more, the ship can be loaded with tanks 10-20 hundreds of landing troops. Medium landing ship, displacement 600 - 1000 tons, range of 1000 nautical miles, can be loaded with the number of tanks, hundreds of landing troops. Landing ship mostly use diesel engine as power plant, speed 12 - 20 knots. Ship loading cabin with ramp board or lift platform, traction winches and so on. The ship has several guns, mainly used for air defense and landing fire support. In addition, there are more complete observation and navigation equipment to ensure navigation safety and communication. The world's first landing ship for the British built in 1940.
Amphibious assault ship
Amphibious assault ship
Amphibious assault ship
To carry helicopters used to transport landing troops and equipment landing ship. Also called helicopter landing transport ship. The main use of helicopters to transport landing troops for vertical landing, in order to improve the suddenness, rapidity and mobility of landing operations. The flight deck of the ship can take off and land 7-8 helicopters at the same time. Below the flight deck are hangars and landing vehicles. The helicopters and vehicles are transported to the flight deck by elevators in the hangar. There is a passage from the landing soldier's cabin to the boarding area. The ship also has a command center, navigation equipment and more complete medical facilities. The United States built "Iwo Jima" amphibious assault ship, full load displacement of 18,300 tons, the maximum speed of 23 knots, can carry 20 helicopters, 4 vertical - short take-off and landing aircraft, the ship is also equipped with aviation missiles and 76 mm guns, but also can be transported to the landing of 2,000 soldiers and weapons and equipment. /p>
Minesweeper
The minesweeper's mission is to remove mines and open up shipping lanes for landing forces, fleets or convoys. Mine is an important maritime defense weapons, mainly laid in straits, waterways and offshore waters, in order to carry out sea blockade and enhance the anti-landing capability. Mine is generally laid in the surface of the water 5-10 meters below the surface, can be loaded with more than 300 kilograms of explosives, powerful and specialized attack on the bottom of the ship, for small and medium-sized ships, such as destroyers, a mine can be blown to the bottom of the sea. In the Second World War, *** more than 2700 ships were sunk by mines. Modern mines are even more varied, there are collision anchor mine, magnetic detonation of mines and sound-controlled mines, etc., no special equipment is more difficult to detect and exclude the ship. Minesweeper that is designed for the elimination of mines and the design of the ship, through the sonar and other equipment for detection, the use of blasting and other methods to implement the elimination of the entire fleet of ships is the protector.
Aircraft Carrier (Aircraft Carrier), referred to as "aircraft carrier", "air carrier", is a kind of military aircraft can provide take-off and landing warships. The Chinese word "aircraft carrier" comes from the Japanese kanji.
Aircraft carriers are a kind of large surface ships with carrier aircraft as the main combat weapon. Modern aircraft carriers and aircraft carriers have become a highly technologically intensive military systems engineering.
Aircraft carriers are generally always the centerpiece of a carrier fleet, and sometimes serve as the flagship of the carrier fleet. It is protected and supplied by the other ships in the fleet. Aircraft carriers allow a nation to exert military pressure and conduct operations far from its own soil and without relying on local airfields.
Aircraft carriers are divided into attack carriers, anti-submarine carriers, escort carriers and multi-purpose carriers according to their missions; aircraft carriers are divided into fixed-wing aircraft carriers and helicopter carriers according to the performance of their carriers; the former can carry and take off and land all kinds of aircraft, including fixed-wing aircraft and helicopters with traditional take-off and landing methods, while the latter can only take off and land helicopters or fixed-wing aircraft carriers with vertical take-off and landing methods. The former can carry and land a variety of aircraft, including conventional fixed-wing aircraft and helicopters, while the latter can only land helicopters or fixed-wing aircraft with vertical takeoff and landing. According to tonnage, there are large aircraft carriers (full load displacement of 60,000 to 90,000 tons or more), medium-sized aircraft carriers (full load displacement of 30,000 to 60,000 tons) and small aircraft carriers (full load displacement of 30,000 tons or less); according to the power of the carriers, there are conventionally-powered aircraft carriers and nuclear-powered aircraft carriers.
