Is the 550 mm thick armor of the ship really 0 55 meters thick steel plates?

Of course, according to the equivalent conversion of the mathematical formula, 1 meter is equal to 1000 mm, and 550 mm is equal to the meter, otherwise you think that there will be a discount and the armor will cut corners? However, the armor protection millimeter mentioned does not mean that the thickness of the steel used in all places is the same. For the armor of **, it generally refers to the thickness of the main armor area in the middle of the hull, but the size of this armor belt is not fully covered, and it will gradually decrease to both sides.

What is the armor for? It is used to protect ** from unsinkable in naval battles, and it is also necessary to ensure that there is a power to return home. Therefore, the armor is used to protect the ammunition depot, because this is the most dangerous place for the whole ship, once it is broken through the ammunition depot and exploded, it will sink directly like the Hood battle cruiser, so the ammunition depot needs armor protection, and in order to go home safely, the reason is to protect the power system from being destroyed, as long as the power system is intact, it is possible to return to the military port for repair, so the engine part also needs to be protected.

However, the tonnage of the first is limited, it is impossible to do everything, and the thickness of the armor is not the same in different positions, the important places are protected by heavy armor, and the unimportant places are directly ignored, the thickness of the steel plate is within 30 mm, but even the thickest part of the main armor of the Yamato-class battleship with a full load displacement of more than 70,000 tons is only 410 mm, and the command tower of the bridge is up to 650 mm, because the tonnage of the battleship is relatively large, so it can balance the performance between tonnage and firepower, maneuver and protection, so the greater the tonnage, the thicker the armor of the battleship.

However, the tonnage of some heavy patrols is limited, so some protection attributes will be given up at some times, although the thickest place can be seen, but in fact, it is just a little bit, and the protection is actually very poor.

Japan's highest level of heavy patrol, the thickest part of the armor is the waterline part of the ammunition depot, and the engine part is only 100 mm.

The U.S. Pensacla-class heavy patrol is also the only place where the waterline of the ammunition depot is protected by armor.

No. There is a standard for the armor protection of ships and tanks, Europe and the United States call it NATO standard steel targets, taking the command compartment of modern ships as an example, the composite bulletproof material is equivalent to the bulletproof ability of how many centimeters of steel plates. Before World War II, ships used heavy armor, and a battleship of more than 60,000 tons cost more than 20,000 tons of steel plates.

When the armor belt below the waterline of the ship wraps the hull, the armor belt is in an arc, and the shells and torpedoes hit the armor, and there is a limit on the angle of penetration to improve the bulletproof ability, and after hitting the armor, it is transmitted to the hull, and the bulletproof and anti-sinking ability of the ship is improved after a layer of buffer. The armor box, like the reactive armor box of a tank, has a bulletproof steel plate at the front and back, which is hollow and improves the bulletproof ability under limited weight. The bulletproof bulkhead compartment, that is, the hull is a double-layer hull, and the double-hull compartment can store fuel and materials, and can also be used as a working compartment for laying pipelines and lines.

The large-scale ** multi-use adjoining cabin in active service.

The equivalent meter thickness homogeneous steel plate is not really a rice steel plate. In those days, there were few meter-thick steel plates in the era of large ships and huge guns, and they were generally within it. Now the steel plates of ships are thinner, they are all thin-skinned dumplings, and supersonic missiles don't care about your thickness, they will be worn when they hit.

Unless you really put on half-meter-thick armor, but the hull is too heavy to run.

What is the equivalent thickness, that is, this strength is equivalent to the protective strength of the standard steel plate, because the ship tank is not made of ordinary steel, there is no protection standard, so its protection standard conversion is the equivalent of the protective strength of how many millimeters of steel plate. Like a nuclear bomb, its power is different depending on the purity of the nuclear material. Therefore, generally speaking, the power of the atomic bomb is said to be the TNT strength of the equivalent, because there is no unified strength standard for nuclear bombs, and the protection of ships, tanks, etc. is the same, and the formula of composite steel used is different, and the protective strength is different, so it is generally converted to the protective strength of general steel plates.

The 550 mm thick armor of the ship is really a meter thick steel plate. A device that doesn't have such a thick splint can't carry that weight. The iron is also its own.

No, the armor of the ships is all special steel, and the equivalence is not the same. Ordinary mild steel plates basically have no bulletproof effect.

It's that thick, it's not equivalent, it's the actual thickness. The steel plate thickness of the front of the Yamato-class main gun turret is up to 650mm, and the thickness of the main armor on both sides is 410mm. The Bismarck has more than 300mm steel plates for full protection. There are more than 20,000 tons of Yamato-class armor.

No. 550 mm refers to a quality steel with a strength equivalent to 550 mm, not necessarily 550 mm.

Yes, and for the sake of the overall solidity of the ship and resistance to artillery shells, it was necessary to thicken the armor.

I only know that the blast door of the underground refuge room is about 20 mm steel plate on the front, and the back is also a 20 mm thick steel plate longitudinally welded into a 200*200 mm square, and the total thickness of the door is about 300 mm.

The hull is made of submarine pressure plates with a thickness of up to 22 28 mm; The underwater part of the hull plate was used to protect against torpedoes and submarine missile bombardment, using steel plates with a thickness of up to 150 203 mm. There are also those made of double or 3-layer hulls.

The construction of a large aircraft carrier requires a wide variety of steel plates, which are generally divided into three categories: hull plates, armor plates and structural plates.

Steel plates for the hull.

Submarine pressure plates for hulls, with a yield strength of 450 MPa and 550 MPa, are delivered with normalization, while 550 MPa plates are delivered with quenched and tempered plate thicknesses up to 22 28 mm. The use of high-strength steel plates can reduce the weight of the hull and increase the resilience. In order to protect the underwater part of the hull sheet from bombardment by torpedoes and submarine missiles, steel plates with a thickness of up to 150 203 mm are used.

There are also double or triple hulls, when the outer plate is damaged, the inner hull is still functional, so as not to sink and have no combat effectiveness.

Steel plates for armor.

Armor plates are mostly used for anti-fog and core parts, such as the command station is the command of the whole ship, protected by armor plates, and it is also the thickest part of the aircraft carrier plates, the thickest armor plates up to 330 mm, and the performance is similar to tank plates. For example, if the nuclear or diesel engine room is damaged, it loses its ability to navigate, so it also needs to be protected with armor plates, and bulletproof armor plates are used for the battery and the above-mentioned hanging armor.

Steel plates for the structure.

The structural plate is mainly used for the runway, the compartment and the hull structure, etc., the thickness of the steel plate used for the general runway is 40 50 mm, and the unevenness is required to be less than 5 mm m, otherwise it will affect the quality of the aircraft lifting, and the larger the plate surface, the better, to minimize the weld. The structural plate requires high strength, reducing the thickness of the steel plate, and reducing the total weight of the hull. The steel used for aircraft carriers, especially the steel used for the flight deck, is extremely demanding, especially for the yield requirements of the material, which is comparable to that of nuclear submarines.

Civilian ships generally only need materials with a strength of 250 MPa, and ordinary military ships are below 300 MPa, and in recent years, the further requirements of cost control, generally adopt many civilian standards, and the material requirements are further reduced, and even the use of aluminum to build the upper deck, but the flight deck standards for aircraft carriers have not been lowered by all countries.

The thickness of the hull steel plates of different aircraft carriers is different.

The thickness of different parts of the same aircraft carrier is also different.

For example, the flight deck of a Nimitz-class aircraft carrier is composed of 50 mm thick steel plates and composite armor materials;

The plate thickness of the access deck is about 14 mm;

The thickness of the board of the hangar deck can reach 38 mm;

The thickness of the deck and platform plates of the remaining decks is 4 7 mm.

The hull steel plate is as thin as the cabin plate 10 mm, as thick as the bow and bottom 25-45 mm thick, some light armor parts and the main engine compartment load-bearing plate may be 40-70+ mm thick, and the key parts of the armor plate are not known.

What is the hardness of an underwater steel plate?

There are actually three types of steel plates used in aircraft carriers

Armor steel plate: used in important protective parts, the thickness is about 30 cm, and it can also be draped with armor.

Hull steel plate: This is no different from the ordinary hull steel plate, the thickness of the steel plate in the ordinary position is about 3 cm, and the underwater may be about 20 cm in order to prevent attack, and the protection can be strengthened in layers.

Structural steel plate: mainly deck steel, with a thickness of about 5 cm. It is the place where it is used most frequently, so the steel requirements are very high, wear resistance, high temperature resistance, corrosion resistance, etc., and most importantly, in order to reduce welds, the larger the steel plane needs to be, the better!

Aircraft carriers in detail

Aircraft carrier, referred to as "aircraft carrier" and "air carrier", is a large surface ship with carrier-based aircraft as its main combat power.

The hull usually has a huge deck and a ship island located on the right side, the aircraft carrier is generally always the core ship of an aircraft carrier battle group, other ships in the fleet provide its protection and supply, and the aircraft carrier provides air cover and long-range strike capabilities.

Relying on aircraft carriers, a country can exert military pressure and conduct operations far from its national territory, without relying on the local airfield situation. Aircraft carriers have become an indispensable weapon of the modern navy and a symbol of a country's comprehensive national strength.

Advantages:

The aircraft carrier is a "sea giant" that integrates various high-tech and many advanced equipment.

Offensive and defensive are especially strong, because the aircraft carriers say that they appear in fleets.

To a large extent, the strength of a country's comprehensive strength can be reflected in the aircraft carrier formation. If a country is not strong in terms of overall strength, it is unlikely to have it.

The construction of aircraft carriers is very important for improving the combat capability of the navies of all countries in the world, and has become a leader in the construction of naval systems and the development of advanced equipment.

Disadvantages

The targets of the aircraft carrier are large and easy to detect.

The aircraft carrier has poor logistics and needs to carry a large amount of fuel and ammunition, plus fuel consumption, food consumption, ammunition consumption, and the fleet needs a very large amount of supplies.

The air defense network is flawed, the aircraft carrier has a small self-defense capability, and relies on the assistance of other ships and submarines and their carrier aircraft, so attacking these "bodyguards" can expose the aircraft carrier's dead end.

Catapults, blockers, radars, and underwater thrusters on the deck of an aircraft carrier are easily attacked and temporarily lose their functions, and they are easily damaged when parked on the flight deck, greatly reducing the offensive and defensive effectiveness of the aircraft carrier.

The combat effectiveness of aircraft carriers is greatly affected by meteorological changes.

Summary

In fact, the strategic deterrence significance of aircraft carriers is far greater than the strategic role, this is the embodiment of a country's overall industrial capacity and comprehensive national strength, without strong industrial strength, economic capacity, and scientific and technological strength, there is no way to manufacture aircraft carriers, and many countries in the world do not manufacture aircraft carriers themselves, they are all imported, which shows this.

Different levels are different, so here you will be the most popular one.

The flight deck of the Nimitz-class aircraft carrier consists of 50 mm thick steel plates and composite armor materials; The plate thickness of the access deck is about 14 mm; The thickness of the board of the hangar deck can reach 38 mm; The thickness of the deck and platform plates of the remaining decks is 4 7 mm. The thickness of the outer bottom plate is about 28 mm; The middle bottom plate is about 12 mm; The inner bottom plate is about 18 mm. The outboard side panel above the waterline is about 38 mm, and the outboard side panel below the waterline is about 24 mm.

The follow-up ships of this class are equipped with Kevlar plates about 64 mm thick in some parts to protect against semi-armor-piercing shells. The thickness of the 5 protective longitudinal wall panels (from the outside to the inside) is mm.

There is also a watertight design.

The following one is speculative.

The thickness of the steel plate is different in different years, different countries, and different positions.

It is said that the defensive ability is equivalent to the defensive effect of an ordinary steel plate with a thickness of 500 mm or 600 mm.

If the armor is really that thick, the weight will be tens or hundreds of tons, and how to walk, the road surface will not be able to stand it.

Well, I don't know, it should be said that the diameter of the bullet is put.

Aren't the numbers already clear? The thickness of the steel plate used is millimeters, the thickness of the steel plate is millimeters, and the thickness of the steel plate is millimeters, and the latter is millimeters.

In fact, many people speculate that the thickness of the deck on the aircraft carrier should be at least 30cm. But the fact is that the deck of the aircraft carrier is not thick, and it can even be described as very thin, and some experts have said that the thickness of the deck of the aircraft carrier is generally between 60mm and 70mm.

550 mm * 550 mm * 5 mm steel plate its weight is kg.

We say that the thickness of tank armor is generally equivalent to how many millimeters of homogeneous steel plate, which does not mean that it is so thick, because modern tanks mostly use composite armor, and that thickness is only an indicator, the actual armor thickness of the tank is very thin, the actual thickness of the front armor of the M1A1 Ebolam is only 130 mm (depleted uranium armor), and China's ZTZ2000 (88C) is only 140 mm (ceramic composite).
