[50] Generational difference

After saying that, I went around and went back, let's go back to the topic of where Cong Qing is strong.

This Congqing belonged to one of the British "Arethusa"-class light cruisers, and was originally called the Alola. It is equipped with four main engines, equipped with four boilers, each with a power of 16,000 horsepower, and a total output of 64,000 horsepower for the four sets, with a maximum speed of 31 knots. Xiaoqiang's introduction of this brigade of large destroyers West Twist only installed two main engines, and two boilers, but can provide up to 72,000 horsepower power output, after 30 years of service, the boiler is slightly aged, although it is not as good as the maximum speed of the new ship when it was just launched 33-34 knots, but it has only decreased slightly, maintaining a maximum speed of 32 knots, which is still faster than the new ship of Congqing.

In terms of weapons, Congqing is equipped with three Mark 13 152MM50 times caliber twin main guns, which are distributed as two in front and one in the rear, and 4 Mark 16 102mm 45 times caliber twin high-level dual-purpose secondary turrets, which are distributed on both sides of the rear chimney and the rear mast; THE WEST TWIST WAS EQUIPPED WITH TWO TYPE 76 130MM 58 TIMES CALIBER TWIN MAIN GUNS, BOTH IN THE FRONT. The caliber is not too bad, but in terms of numbers, one has 14 guns, and the other has 4.

The 152MM twin main gun of the Mark 13 on the Congqing can fire 8 shells per minute, and the maximum firing range can be 23,317 meters at a 45-degree elevation angle, and the maximum rate of fire of the 102MM twin secondary gun of the Mark 16 can reach about 20 rounds per minute, and the maximum firing range is 19,500 meters, according to the number of shells fired, the Congqing can fire 208 shells per minute.

The Type 76 130mm double-barreled naval gun on the West Twist can easily shoot shells out of an effective range of 15 kilometers per minute at a rate of 23 rounds, and the 4-barreled gun fires 60 shells per minute.

In terms of safety, the Mark 13 and 16 naval guns were open, while the Type 76 had a closed turret with a high level of gunner safety under thick turret armor.

On the surface, it seems that one firepower is fierce and one turret is well protected, so if it is an artillery battle, which one has the advantage?

In fact, the answer is very simple, the West Twist does not use missiles, and when I saw a World War II cruiser like Congqing, I also saw one and extinguished the other, that is, Yujian's super battleship with rough skin and thick flesh, and if it can't be sinked, it can beat him to the point that the deck is on fire, and he is covered in injuries.

Let me explain the reason, in fact, in general, the reason is that modern warships are basically not comparable with warships during World War II, and the above comparisons are basically a perjury. Weishenme says so?

Because the naval guns in World War II relied on the gunner's manual shelling, the so-called fire control radar could only give a relatively accurate azimuth parameter and then let the gunner adjust it himself, which is the approximate direction and approximate distance. The most intelligent battleship of World War II, the Iowa of the United States, has just had the concept of a fire control system, and there is a computer to calculate the shooting elements, and the "Exocet" hand-cranked mechanical computer is still used, and you don't have to count on the speed, and the accuracy of the data collected by the radar in those years is not reliable, and the effective range of naval warfare is fired (that is, two-thirds of the maximum range), and the hit rate of 2 percent is already a very good achievement. As for other ordinary warships, where is the concept of a fire control system, they are basically not interested in fire control radar, as long as they can see the opponent, they are basically observers and artillery commanders who are doing it: "There are warships over there!" near, corrected; Far away, fix ......", next: "The radar found that the warship is still there!" Didn't sink, didn't sink, didn't sink......"

However, modern warships have achieved microcomputer control, such as the brigade-level West Twist under the guidance of the "Wasphead" (343) gun-second radar, and the automation ability and accuracy of the artillery are terrifying. The west twist 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 a three-dimensional coordinate distance accurate to the centimeter, the computer automatically calculates the shooting elements according to the tilt data and the three-dimensional coordinate distance provided by the fire control radar, and the calculation is completed in an instant and inputs the artillery, the gun rotates and swings up and down at high speed through electronic control, and the independent stabilization mechanism of the gun makes the gun basically not affected by the swing of ordinary sea conditions when firing. Within the effective range of naval warfare (that is, two-thirds of the maximum range), the lowest rate of fire is more than 50 percent. Even after the failure of the electronic control system, manual control can be applied, and the angle and orientation of the gun can be manually and mechanically adjusted according to the shooting parameters provided by the computer, and the accuracy of the shelling is not to be said.

In addition, modern naval artillery pays attention to the speed of fire delivery, and a slow rate of fire means that the opponent is no longer in place the next time the gun is fired, so your artillery firing parameters will have to change. This is not a problem for the fire control system of modern warships, but for warships of 1949, a slow rate of fire means a decrease in accuracy. The rate of fire of the 152mm Mark 13 gun of 8 rounds per minute doomed him to be a fool to take a look at, and if he could hit the high-speed moving West Twist, it would really be called pie in the sky.

Let's take a look at the double diameter of the artillery, the double diameter of the Type 76 130mm twin naval gun is 58 times, while the double diameter of the 152mm Mark 13 twin naval gun is only 50, and the double diameter of the 106mm Mark 16 double ship gun is only 45. Because the longer the warhead of a tubular gun is affected by the gas generated by the propellant in the barrel, the higher the muzzle velocity, the greater the energy, and the trajectory is more flattened, which also has a positive impact on the firing range, so theoretically, the longer the length of the barrel, the better. When comparing the power of two guns of the same caliber, the magnitude of the double diameter is a very good reference. The larger the multiplier, the longer the barrel and the more powerful.

The actual power of the Type 76 130mm twin naval gun is much greater than that of the 50 times the caliber of the 152mm Mark 13 twin naval gun. In addition, the technological level of modern artillery has improved much compared to World War II: the material of the breech and the rifling design are not what they used to be; scientific and technological advances in explosives; The calculation and study of the damaging effect of artillery shells is also a heaven and an underground compared to World War II. Someone once made an unofficial calculation that the power of two guns of the same caliber during World War II was only a quarter of the power of modern guns of the same caliber, and the difference in reality may not be so great as this, but I can tell you one thing that the power of modern artillery cannot be compared with the caliber of artillery during World War II.

During the Sino-Japanese First Sino-Japanese Naval Battle, seven or eight Japanese warships surrounded and beat the two ships for several hours, but the town remained unsinkable...... During World War II, three British cruisers besieged the German Admiral Spee pocket battleship, and fought from dawn to late at night, Admiral Speeh was seriously injured and escaped ......, and one of the three British cruisers returned to port with heavy damage, and two were lightly wounded...... Today's Type 76 130mm 58 times the diameter twin naval gun, with only 6 shells, can blow up a 3,000-ton battleship, it is a well-known madness and powerful naval gun......

Integrating the above examples and data, it can be learned that the power of naval guns has risen and developed at a rate far greater than that of warships.
