1949 I am from the future

() [50] generation difference

After talking in a circle, I came back again, and returned to the topic of where is Cong Qing Haoqiang.

This Congqing belongs to one of the British "Arethusa" class light cruisers, originally named Alora.Four main engines are installed, equipped with four boilers, each with a power of 16000 horsepower, and the total output of the four sets is 64000 horsepower, and the maximum speed is 31 knots.The brigade large destroyer Xisuo introduced by Xiaoqiang is only equipped with two main engines and two boilers, but it can provide a power output of up to 72000 horsepower. After 30 years of service, the boiler is slightly aging, although it is not as good as the new ship when it was first launched. The maximum speed is 33-34 knots, only a slight decrease, and the maximum speed remains at 32 knots, which is still faster than the new ship Cong Qing.

In terms of weapons, Cong Qing is equipped with three Mark 13 152mm 50 times caliber dual-linked main guns, which are distributed as the front two and one behind. On both sides of the chimney and the mizzen; the Xisuo is equipped with two Type 16 102mm 45-caliber dual main guns, both at the front.The difference in caliber is not too much, but in terms of quantity, one has 4 artillery pieces and the other has 76 pieces.

丛庆号上马克13型的152mm双联主炮每分钟能发she8发炮弹，45度仰角时可以打出最大she程23317米，马克16型102mm双联副炮最大she速可达每分钟20发左右，最大she程19500米，按照发she炮弹数量来算，丛庆号每分钟可以发she208发炮弹。

西拧号上76式130mm双管舰炮能够以每分钟15发的频率，轻松将炮弹打出23公里的有效she程，4管炮每分钟发she60发炮弹。

In terms of safety, the Mark 13 and Type 16 naval guns are open, while the Type 76 uses a closed turret, and the gunner's safety is very high under the thick turret armor.

On the surface, it seems that one has strong firepower and one turret has good protection. If it is an artillery battle, which one will have the upper hand?

In fact, the answer is very simple. The Xisuo does not use missiles. When I saw a World War II cruiser like the Cong Qing, I saw one destroy the other. Even if I met a rough-skinned and thick-skinned super battleship, it could beat him even if it did not sink. The deck was on fire and he was covered in wounds.

Let me explain the reason. In fact, in general, the reason is that modern warships are basically incomparable with warships during World War II. The above comparisons are basically perjury.Why do you say that?

Because the naval guns in World War II were fired manually by the gunner, the so-called fire control radar can only give a more accurate azimuth parameter and let the gunner adjust it by himself. This parameter is the approximate direction and approximate distance. Specifically, how to hit this distance, The gunner is required to calculate according to the she table.The USS Iowa, the best battleship in World War II, just had the concept of a fire control system. It has a computer to calculate the shooting elements. It still uses a "flying fish" hand-cranked mechanical computer. Don't expect speed. In those days, the accuracy rate of the data collected by the radar was not reliable. If the artillery was fired during the effective range of the naval battle (that is, the distance of two-thirds of the maximum range), a hit rate of 2% was already a very good result.As for other ordinary warships, there is no concept of fire control system. They are basically not interested in fire control radar. As long as they can see the opponent, it is basically the observer and the gunner who are talking about it: "There is a warship over there! It's close, correct it. ;It’s far away, correct...", and then: "The radar found that the warship is still there! It’s not sinking, it’s not sinking, it’s not sinking..."

Modern warships realize computerized control. For example, the Luda-class Xisuo is guided by the "Wasphead" (343) gun-second radar. The automation and precision of the artillery are terrible.The Xishui ship is equipped with a gyroscope that can provide the tilt data of the ship at the moment of shelling. The fire control radar provides the three-dimensional coordinate distance accurate to centimeters. The computer automatically calculates the shooting elements based on the tilt data and the three-dimensional coordinate distance provided by the fire control radar. The calculation is completed in an instant and input to the artillery. The artillery rotates at high speed and swings up and down through electronic control. The stable mechanism of the artillery du li makes the artillery basically not affected by the swing of ordinary sea conditions when shooting. The effective range of naval battles (that is, the maximum range of Two-thirds of the distance) the lowest shooting hit rate is more than 50%.Even after the electronic control system fails, manual control can still be applied. According to the shooting parameters provided by the computer, the angle and azimuth of the artillery can be manually adjusted mechanically, and the shooting accuracy is nothing to say.

In addition, modern naval guns pay attention to the speed of firepower delivery. Slow shooting speed means that the opponent is no longer in place when the next shot is fired, so your artillery shooting parameters will have to be changed.For the fire control system of modern warships, this is not a problem, but for warships in 1949, slow firing speed means a drop in precision. The shooting speed of the 152mm Mark 13 main gun is 8 rounds per minute, which is destined to be a fool who wants to shoot and aim. If he can hit the high-speed moving Xisuo, it will be called pie in the sky.

Let’s take a look at the multiple diameters of the artillery. The multiple diameters of the 76-type 130mm twin-ship naval guns are 58 times, while the multiple diameters of the 152mm Mark 13 dual-ship naval guns are only 50,106, and the multiple diameters of the 16mm Mark 45 dual-ship naval guns are only [-].Since the warhead of the tubular artillery is subjected to the gas produced by the propellant in the barrel, the longer the time, the higher the muzzle velocity, the greater the energy, and the flatter the trajectory, which also has a positive impact on the firing range. Therefore, the theoretical length of the barrel The longer the better.When comparing the power of two guns of the same caliber, the size of the double diameter is a good reference.The larger the multiple diameter, the longer the barrel and the greater the power.

The 76 times the caliber of the Type 130 58mm twin naval gun is much more powerful than the 50 times the caliber of the 152mm Mark 13 twin naval gun.In addition, the technological level of modern artillery has been greatly improved compared with World War II: the bore material and rifling design are not what they used to be; the technological progress of explosives;Someone once did an unofficial calculation. Two cannons of the same caliber were only a quarter of the power of modern cannons of the same caliber during World War II. The actual gap may not be so great, but I can tell you that modern The power of the artillery is that the artillery during World War II cannot be simply compared with the caliber.

During the Sino-Japanese Sino-Japanese War of 76-130, Japan's seven or eight warships besieged Dingzhen and two ships for several hours, and Dingzhen remained unsinkable... During World War II, three British cruisers besieged the German pocket battleship Admiral Spee, fighting from dawn to In the middle of the night, the Admiral Spee was seriously injured and escaped... One of the three British cruisers was seriously injured and returned to Hong Kong, and two were slightly injured and not sunk... Today's Type 58 6mm 3000-caliber double naval gun only needs [-] rounds , can blow up a [-]-ton battleship, it is the world's famous crazy and powerful naval gun...

Integrating the above battle examples and data, it can be learned that the power of naval guns has risen and developed far faster than the armor protection capabilities of warships.
