In the windward state, there is more than 30 knots of deck wind, which is completely sufficient, and it is basically impossible to increase the speed. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Because the maximum speed of the draft conventional monohull large ship, every time one unit is increased, the maximum power of the main engine required is almost between the quadratic and the cubic of the original unit, that is to say, it is impossible for the conventional ship to increase the maximum speed unlimitedly, because this requires the power of the power system to skyrocket exponentially, which is impossible for the current human internal combustion engine and steam engine system.

Aircraft carriers are highly maneuverable special airfields with surface mobility;

The significance of high maneuverability to take-off and landing aircraft has been mentioned earlier, so as a surface ship, it will inevitably face three threats: underwater, surface, and air, and the underwater danger has always been the biggest threat faced by aircraft carriers;

Although the aircraft carrier is a cow, the danger from under the water is the most deadly;

In the face of threats from other ships in the air and on the surface, aircraft carriers can detect these threats in advance and strike first because of the superiority of carrier-based aircraft in large-scale and large-radius operations and early warning aircraft battlefield perception.

And for underwater dangers, no matter how advanced anti-submarine measures are, they cannot be 100% guaranteed to be reliable, practice has proven countless times, even at present, the aircraft carrier is still most afraid of elusive submarines, especially nuclear submarines,

Modern submarines are no longer World War II when they can only observe periscopes and attack in a straight line at close range, modern submarines can launch submarine-launched missiles from 100 nautical miles away with the support of data links, and

Since water is more than 800 times denser than air, the same blow up of a destroyer of seven or eight thousand tons can resist a direct hit by two or three Harpoon missiles. Not to sink immediately,

However, if the same destroyer is directly hit by an MK heavy torpedo, the keel will be blown off, the whole ship will be split in half, and the crew will be able to escape, even if they are not immediately killed

This is true for destroyers, then the same is true for aircraft carriers, an aircraft carrier of 6-100,000 tons can be directly hit by 10 harpoons, and will not sink immediately, and also since World War II, submarine torpedo anti-aircraft carriers are the most efficient and cost-effective, sinking more than 30,000 tons of Yorktown aircraft carriers' little devil's submarines, only a thousand tons, because as long as it can launch heavy torpedoes, the size of the submarine itself does not matter,

At present, conventional submarines and nuclear submarines can carry heavy intelligent torpedoes and long-range submarine-launched anti-ship missiles, while nuclear submarines and AIP conventional submarines can be ambushed in a large range for more than a few weeks, so the threat of advanced submarines to aircraft carriers has not only not decreased, but greatly increased the threat coefficient;

As a kind of floating ship on the surface, no matter how powerful the aircraft carrier is, it will also sink

It is difficult to counter submarines in advance, so there is only one way for aircraft carriers to counter submarines, and they can't afford to hide, that is, to avoid and disengage from the submarine as soon as possible through high maneuverability and high speed;

High speed

Nuclear submarines can be underwater for more than 30 knots, but no matter how advanced the nuclear submarine, once the underwater exceeds 20 knots, then the noise will increase exponentially, to about 30 knots, and it is impossible not to be exposed, so even if the advanced nuclear submarine, the general underwater will not exceed the cruising combat speed of 20 knots, close to 30 knots, and it will only be used when it is exposed to escape for its life, or when it follows the formation at high speed.

Therefore, as the main force of surface warfare, the aircraft carrier and its formation, can maintain a high speed for a long time, which is a very important tactical parameter for its own combat and evasion of underwater threats, once the aircraft carrier formation exceeds 30 knots, and constantly in the vast waters

There is an exponential relationship between the maximum speed of large ships and the power output, and for modern aircraft carriers, 27 knots is basically the minimum threshold for speed;

Large ships with a full displacement of more than 50,000 tons basically have no maximum speed of more than 35 knots, and civil ships do not exceed 30 knots

It is already the highest speed of large ships galloping at high speed on the ocean, because the timeliness of container cargo is relatively high, so the speed of this large ship is relatively fast, this kind of container liner, Panama class in 5 to 70,000 tons, more than 80,000 tons of super Panama class, the largest container clipper, about 100,000 tons, hull width of nearly 50 meters, length of more than 300

It's just that the deck of the aircraft carrier floats relatively large and the top is relatively wide, and the width of the waterline under the deck of the aircraft carrier is also between 45 meters and 50 meters, and the maximum sustained speed of modern large ships regardless of steam, gas or diesel is between 25 and 35 knots, and the long-term high speed of the aircraft carrier when retracting and releasing carrier-based aircraft, and under low sea conditions, 30 knots is basically enough, and it is basically impossible to increase the speed.

Because the maximum speed of the draft conventional monohull large ship, every time one unit is increased, the maximum power of the main engine required is almost between the quadratic and the cubic of the original unit, that is to say, it is impossible for the conventional ship to increase the maximum speed unlimitedly, because this requires the power of the power system to skyrocket exponentially, which is impossible for the current human internal combustion engine and steam engine system.

Modern submarines can only launch submarine-launched missiles from 100 nautical miles away with the support of data links, and modern intelligent torpedoes can launch deadly attacks with multiple salvos dozens of nautical miles away; Once locked by a smart torpedo, any large ship will almost have to sit still, because modern times there are no particularly effective measures against smart torpedoes;

Since the density of water is more than 800 times that of air, the same explosive yield, the power of explosion in water is many times stronger than that of an explosion in air, and any ship hit by a torpedo is more destructive than being hit by missiles and artillery shells, and the destructive power is much more serious, and a destroyer of seven or eight thousand tons can resist a direct hit by two or three Harpoon missiles. It will not sink immediately, at least half of the crew will have time to abandon ship and flee for their lives, or have time to extinguish the fire and rush to repair it;

However, if the same destroyer is directly hit by an MK heavy torpedo, the keel will be directly blown off, the whole ship will be split in half, and even if the crew is not immediately shocked to death, then no more than 20% will be able to escape, and if it is directly hit by a heavy torpedo, there is almost no need to rescue again;

If a destroyer is like this, then the same is true for aircraft carriers, an aircraft carrier of 6-100,000 tons can be directly hit by 10 harpoons, but will not sink immediately, while the same aircraft carrier, if it is directly hit by 2 or more heavy torpedoes, then there is absolutely a danger of capsizing, at least it must be tilted immediately and lose its combat effectiveness, and the aircraft carrier that loses power will become a real giant target, and its fate will be very tragic;

Since World War II, submarine torpedo anti-aircraft carriers are the most efficient and cost-effective, sinking more than 30,000 tons of Yorktown aircraft carrier's little devil's submarine, only a thousand tons, because as long as it can launch heavy torpedoes, the size of the submarine itself does not matter, the smaller the concealment, the better;

At present, conventional submarines and nuclear submarines can carry heavy intelligent torpedoes and long-range submarine-launched anti-ship missiles, while nuclear submarines and AIP conventional submarines can be ambushed in a large range for more than a few weeks, so the threat of advanced submarines to aircraft carriers has not only not decreased, but greatly increased the threat coefficient;

In the face of various advanced conventional and nuclear submarines, it is almost difficult for aircraft carriers to detect and strike ahead of time like other surface ships and aircraft, because advanced submarines are extremely concealed, and they can attack from a long distance, and it is becoming more and more difficult to counter-attack submarines in advance;

High speed, high maneuverability, to the aircraft carrier itself and the aircraft carrier formation, is of great significance, high speed is very positive to the carrier-based aircraft, and the anti-underwater submarine threat is equally important, conventional submarines, it is difficult to exceed 20 knots underwater, and when using the AIP system to cruise operations, it can hardly exceed 5 knots;

Nuclear submarines can be underwater for more than 30 knots, but no matter how advanced the nuclear submarine, once the underwater exceeds 20 knots, then the noise will increase exponentially, to about 30 knots, and it is impossible not to be exposed, so even if the advanced nuclear submarine, the general underwater will not exceed the cruising combat speed of 20 knots, close to 30 knots, and it will only be used when it is exposed to escape for its life, or when it follows the formation at high speed.

Therefore, as the main force of surface warfare, the aircraft carrier and its formation, can maintain a high speed for a long time, for its own combat and evasion of underwater threats, is a very important tactical parameter, once the aircraft carrier formation more than 30 knots sailing, and constantly change direction and maneuver in the vast waters, then whether it is a conventional submarine or a nuclear submarine, it is difficult to ambush such a formation, and a conventional submarine wants to pursue the nuclear submarine formation, at present, it is simply not possible.

There is an exponential relationship between the maximum speed of large ships and the power output, and for modern aircraft carriers, 27 knots is basically the minimum threshold for speed;

Full displacement of more than 50,000 tons of large ships, basically no can exceed the maximum speed of 35 knots, civil ships do not exceed 30 knots, modern sustained high speed of large civil ships, generally container liners, cruising speed can reach more than 20 knots, the most advanced continuous speed can reach 25 knots, this is already the current high speed of the ocean galloping at the highest speed of large ships, because the timeliness of container cargo requirements are relatively high, only the speed of this large ship is faster, this container (to be continued. )
