The deck thickness of an aircraft carrier will be slightly different for different purposes, and the thickness of different countries will be slightly different due to different technologies and materials. The flight deck of an aircraft carrier is generally composed of 50 mm thick steel plates and composite armor. The channel deck is about 14 mm, and the hangar deck is 38 mm thick. The deck thickness of important parts such as ammunition depot, nuclear energy or diesel engine room may reach 65 mm, but the thickness of several tens of mm is not generally strong. There are two major aircraft carriers in China, but how thick are their decks? The truth is unbelievable.
Before we know the aircraft carrier in detail, according to normal people's thinking, the deck of the aircraft carrier is the main carrier for bearing and supporting, and its thickness must be very large. After all, it must be very thick because it is often subjected to fighter planes and warships and artillery shells. But the fact is that the deck thickness of the aircraft carrier is not very high, not even as high as that of ordinary warships.
This kind of deck protection ability is a little weak compared with tanks and even planes, but it is not difficult to understand the operational mode of aircraft carriers. As a military weapon, aircraft carriers fight in groups when attacking and sailing. Surrounded by a large number of frigates and destroyers, they are escorted by reconnaissance planes in the air and cruise back and forth underwater. Its function is more like a base for command and logistics support. There are two major aircraft carriers in China, but how thick are their decks? The truth is unbelievable.
The thickness of the aircraft carrier deck has reached the standard, but the hardness has not yet reached the standard. It also needs high temperature resistance and corrosion resistance. When the carrier-based aircraft takes off, the flame emitted by the engine is several thousand degrees, and the general steel melts instantly. Speaking of corrosion resistance, we all know that after the rust on the surface of the carrier Varyag built by the former Soviet Union was wiped off, the steel plate was still no different from the new one. Carrier aircraft weighing more than 30 tons hit the deck at high speed, and the deck will not be deformed or even damaged.
The flight deck is the upper deck on the surface of the aircraft carrier, which is used for the take-off and landing and parking of carrier aircraft, also known as the ship surface field. Because of the low take-off and landing speed, early aircraft can take off from the small deck laid on the bow or upper part of the main turret of a warship and land on the short deck at the stern. But modern aircraft carriers are large upper decks that run through the whole ship. Finally, it is also because modern aircraft carriers use all-metal flight decks. In order to improve friction, the deck surface will be coated with a layer of solid flight deck paint. It can also effectively avoid the side slip of the plane and the fall of people caused by the turbulence of the waves.
