It is only 80 mm but can withstand indiscriminate bombing
Not all countries can manufacture the steel used in the aircraft carrier deck. India’s new aircraft carrier needs special steel imported from abroad. Thousands of kilograms, the steel used on the decks of Chinese, American and Russian aircraft carriers is actually not very thick, only about 80 millimeters.
The United States once tested that a 30-ton heavy fighter jet hit the aircraft carrier deck at high speed when landing. The aircraft carrier deck was not damaged. Not only did it not deform, but the traces of the explosion were very small. It can be imagined that the aircraft carrier steel of durability and strength.
Of course, for some core locations of the aircraft carrier, such as the command center and the aircraft carrier's power system, armored steel plates will be used in these locations, with a maximum thickness of 330 mm, which is somewhat similar to the armored steel plates used in tanks. In order to prevent bombardment by torpedoes and submarine missiles, the underwater part of the hull is made of steel plates with a thickness of 150 to 200 mm.
Deck thickness is not really an important indicator on an aircraft carrier. Instead, the thinnest steel plate should be used as much as possible while ensuring the same protective effect. The surface of the steel plate of the Varyag was stained with rust at first, but the performance of the steel plate itself has not declined at all. After the rust is wiped off, the performance of the steel plate is basically the same as that of a brand new one. Therefore, such steel can be manufactured in large quantities in our country.

Classification of aircraft carriers
Generally speaking, aircraft carriers mainly have the following types: according to the tasks they undertake, they can be divided into attack aircraft carriers, anti-submarine aircraft carriers, Escort aircraft carriers and multi-purpose aircraft carriers; according to the type of carrier-based aircraft, they can be divided into fixed-wing aircraft carriers and helicopter aircraft carriers; according to tonnage, they can be divided into large aircraft carriers, medium-sized aircraft carriers and small aircraft carriers; according to power, they can be divided into conventionally powered aircraft carriers and nuclear powered aircraft carriers aircraft carrier.
Mission classification, according to the type of mission performed, is divided into attack aircraft carriers, anti-submarine aircraft carriers, escort aircraft carriers and multi-purpose aircraft carriers. Attack aircraft carriers mainly carry fighter jets and attack aircraft, while anti-submarine aircraft carriers carry anti-submarine helicopters. The multi-purpose aircraft carrier carries both helicopters, fighter jets and attack aircraft. Most of the aircraft carriers equipped by various countries are multi-purpose aircraft carriers.
Displacement classification, super aircraft carrier (full load displacement of 80,000 tons and above); large aircraft carrier (full load displacement of 60,000 tons to 80,000 tons); medium aircraft carrier (full load displacement of 30,000 tons to 60,000 tons) and Small aircraft carrier (full load displacement less than 30,000 tons).
Carrier-based aircraft are classified into fixed-wing aircraft carriers, short take-off and landing aircraft carriers and helicopter aircraft carriers. The former can take off and land various aircraft including fixed-wing aircraft and helicopters with traditional take-off and landing methods. , generally with a tonnage of more than 40,000 tons, currently equipped with equipment from the United States, Russia, Britain, China, and India.
The middle ones can only take off and land helicopters or fixed-wing aircraft that can take off and land vertically. They have smaller tonnage, usually small and medium-sized aircraft carriers of 40,000 to 20,000 tons, mostly from Western Europe. National equipment. The latter has the smallest tonnage and can only carry certain helicopters and a small number of vertical takeoff and landing fighters.
Power plant classification, nuclear-powered aircraft carriers and conventional-powered aircraft carriers. Nuclear-powered aircraft carriers use nuclear reactors as their power plants. Conventionally powered aircraft carriers use steam turbines as their basic power. The disadvantage of conventionally powered aircraft carriers is that they have a huge chimney, which is very obstructive and easily exposes targets.
Nuclear-powered aircraft carriers do not have chimneys. Moreover, the endurance of nuclear-powered aircraft carriers is much greater than that of conventionally-powered aircraft carriers. For example, the U.S. "Nimitz"-class nuclear-powered aircraft carrier can travel 100,000 nautical miles at a maximum speed of 35 knots (the equatorial circumference is 30,000 nautical miles) when fully loaded with nuclear fuel.
In addition, the navies of some countries have a similar-looking ship called an "amphibious assault ship", which can also take off and land military helicopters or fixed-wing aircraft that can take off and land vertically. This kind of amphibious landing ship is like a reduced aircraft carrier and has a wide range of uses. It is mainly used as a means of transportation for beach landing.
