Chapter 1480

Qin Guan knew that in the history of that parallel moment, Dr. bull proposed to build 203 mm artillery in China.

In fact, this caliber, in the era of battleships, is the most common kind of artillery. However, artillery technology is constantly developing. Now the 155 mm howitzer can hit 40 kilometers. What about before? In the battleship era, you couldn't reach 20 kilometers.

Therefore, this 203 mm gun is absolutely different from the 203 mm gun of previous battleships, and its power must be greatly increased.

In history, the 203 mm gun of the Han Dynasty has gone through twists and turns. It was originally launched. However, when the development came to an end, it was finally dismounted because of lack of funds. Moreover, it lost its value with the disappearance of the threat from the north, and finally began to sell internationally.

The largest caliber gun in the Han Dynasty is still the 155mm gun. The performance of this gun is quite moderate. If the caliber is larger, the weight of the gun will be very large. It is very difficult for the artillery to operate.

After all, the greatest threat of artillery is the enemy's artillery. If you fire a few guns, you have to change places. Otherwise, why is self-propelled artillery popular? When your artillery position is detected by the other party, the other party will return fire with covered artillery.

Now, anyway, the journey back is long. Qin Guan might as well have a chat with Dr. bull.

Qin Guan now said that the range of 200 kilometers, Dr. bull shook his head: "difficult."

"Why?" Qin Guan asked.

"If we want to achieve such a high range, we need to greatly increase the propellant and the length and weight of the barrel. In this way, this kind of artillery has no mobility at all. As a mobile artillery force of the army, it is too cumbersome and the launch is complicated." Dr. bull made a careful analysis: "If we want to make an analogy, the previous William cannon, with a caliber of 210mm and a length of 36m, only achieved a range of about 120km. It is not difficult to use the current technology to achieve a range of 200km. However, it can not be used as a ground mobile weapon of the army, but only as a fixed weapon, just like the Dora cannon."

When Dr. bull said this, his eyes suddenly flashed: "if you want to be a fixed weapon, it's better to greatly increase its caliber. Anyway, it can't move. If you increase the caliber to 800 mm or even one meter, the range and power will be greatly improved."

Qin Guan shook his head. This guy directly extended to his super cannon.

"Without this intermediary, we can not directly transfer to this kind of cannon. We must first meet the use of the army in order to obtain the recognition of the military." Qin Guan said: "you should know that our country's economy has just begun to develop, and it is impossible to use high investment in a project that does not see benefits."

Dr. bull frowned and meditated. Qin Guan was also stunned. This guy didn't think he was fooling him, did he?

Qin Guanzheng wanted to explain again, so he heard Dr. bull continue to speak: "if it's a naval gun of this caliber, I think it's more suitable to install it on a warship. Have you heard of the mark71 203 mm naval gun of Eagle country?"

Qin Guan didn't really understand the cannon. Now, hearing what Dr. bull said, Qin Guan shook his head: "I don't know much."

"At that time, the active artillery of the eagle navy was not powerful enough, so they began the research program of large caliber light naval gun. The development result of this program was the mk71 8-inch 55 times diameter single barrel naval gun." when talking about the gun, Dr. bull was endless.

"The biggest feature of this kind of artillery is that it is light. The previous 203 mm naval gun can only be carried by 10000 ton warships. However, they have achieved the goal of carrying on a Forrester Sherman destroyer with a full displacement of only 4050 tons."

As long as it is artillery, Dr. bull is like a treasure. Because of its bulkiness, he usually carries it on warships. During World War I, it was the duel of giant guns, which made people look very powerful and spectacular.

However, modern naval guns are different from the previous ones. They pursue lightness.

"This mk71 naval gun system includes a lightweight 203 mm barrel, turret, automatic ammunition feeding device and control platform. It is a highly automated modern single barrel naval gun system. By analogy, the barrel length of mk71 naval gun is the same as that of mk16 203 mm naval gun equipped on Des Moines class heavy cruiser, both of which are 55 times the diameter, but the barrel weight of mk71 is only about 9 tons, while MK1 The barrel weight of 6 has reached 17.14 tons. "

Such a comparison shows how light it is.

"At the same time, the turret of this single barrel naval gun uses a lot of aluminum alloy, and the weight of the rotating part of the turret is only 7.8 tons." Dr. bull said: "for you, if you have this kind of naval gun, you can carry it on a large number of your destroyers in service."

If it hadn't been for President Carter, this guy had been shouting peace, reducing troops and reducing military spending, otherwise this kind of gun would have been in service long ago.

Now, I came to the Han state to help them realize the large caliber of naval guns. Should they pay attention to themselves?

Dr. bull looked at Qin Guan, and at this time, Qin Guan was also thinking about Dr. bull's proposal.

In modern naval warfare, missiles are the mainstream. However, naval guns have not been abandoned. Looking at all warships, they will have a naval gun at the bow. We know that this belongs to the evergreen tree of Shipborne weapons.

Well, since it is necessary to equip naval guns, there is a problem of choosing the caliber of naval guns. In the past, the Han country was mainly the system of the Xiong country, so the caliber of naval guns was also based on the system of the Xiong country. However, he soon fell behind and was in a honeymoon with the West. Therefore, he naturally aimed at the West.

At that time, the mk-45 127 mm naval gun produced by Yingguo and the 114 mm naval gun produced by NiuGuo could be selected, but at that time, the tonnage of the drive and protection ships of Han was generally small, so these naval guns seemed too heavy.

Therefore, after careful selection, Han focused on the t100c compact single barrel 100mm naval gun developed by Jiguo. This gun has light weight and is convenient to be arranged on destroyers and frigates. The maximum range can reach 17.5km and the maximum firing speed is 90 rounds / min. the whole gun has a high degree of automation and excellent performance.

At that time, with limited funds, the state of Han purchased two single barrel 100mm naval guns, one was installed on the frigate Siping, and the other was disassembled for imitation.

But later, with the development of the Navy, this kind of gun became a chicken rib. Compared with the 127 mm gun, its range was seriously insufficient, and compared with the 76.2 mm gun, its firing speed was insufficient. Therefore, it was soon eliminated.
