Chapter 1480: As a naval gun

Qin Guan knew that in the history of that parallel moment, it was Dr. Bull who proposed to use 203mm guns for the country.
In fact, this caliber was the most common type of artillery in the battleship era. However, artillery technology is constantly developing. The current 155mm howitzer can hit 40 kilometers. How about before? In the era of battleships, 20 kilometers could not be reached.
Therefore, this 203 mm caliber gun is absolutely different from the 203 mm naval gun of the previous battleship, and its power must be greatly increased.
In history, this 203mm gun of Han State has gone through ups and downs. It had already been launched. However, when the development was coming to an end, it was finally dismantled due to insufficient funds, and also with the disappearance of the northern threat. Lost value, and finally began to sell internationally.
The largest caliber of the Han country is still a 155mm gun. The performance of this gun is quite moderate. If the caliber is larger, the gun's own weight will be very large, and it is quite difficult for artillery to operate.
After all, the biggest threat to artillery is the enemy’s artillery. If you fire a few shots, you have to change places. Otherwise, self-propelled artillery will become popular. When your artillery position is detected by the opponent, then the opponent will carry out covering artillery fire. It fought back.
Now, anyway, the journey back is a long one, and Qin Guan will just chat with Dr. Bull.
Qin Guan now talked about a range of 200 kilometers, and Dr. Buhl shook his head: "Difficult."
"Why?" Qin Guan asked.
"If we want to achieve such a high range, then we need to increase the propellant a lot, increase the length and weight of the barrel, so that this artillery has no mobility at all, as a mobile artillery force of the army. , It’s too heavy and it’s too cumbersome to launch.
Dr. Bull made a careful analysis:
If we want to compare, the previous William Cannon, with a caliber of 210 mm and a length of 36 meters, achieved a range of about 120 kilometers. With the current technology, it is not difficult to achieve a range of 200 kilometers. However, it cannot be used as a ground mobile weapon for the army. It can only be used as a fixed weapon, just like the Dora cannon."
When Dr. Bull said this, his eyes suddenly flashed light: "If it is to be used as a fixed weapon, it is better to increase its caliber greatly. Anyway, it cannot be maneuvered. If the caliber is increased 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't directly transition to this cannon. We must first satisfy the military's use before gaining the military's approval." Qin Guan said, "You should know that our country's economy has just begun to develop. It’s impossible to spend a high amount of investment on a project with no visible benefits."
Dr. Bull frowned and started thinking. This made Qin Guan also stunned. Doesn't this guy think he is fooling him?
Qin Guanzheng wanted to explain more, he heard Dr. Bull continue to speak: "If it is a naval gun of this caliber, I think it is more suitable to be installed on a warship. You have heard of the Mark 71203 mm naval gun of Eagle Country. ?"
Qin Guan really didn't understand the artillery thing very well. Now, after hearing Dr. Bull say this, Qin Guan shook his head: "I don't know much."
"At that time, the active artillery of the Eagle State Navy was not powerful enough, so they started a research plan for large-caliber light naval guns. The result of this plan was the MK71 8-inch 55-diameter single-barreled naval gun." Speaking of the artillery, Dr. Bull was eloquent.
"The biggest feature of this type of artillery is its lightness. The previous 203mm naval guns could only be carried by 10,000-ton warships. However, they achieved a fully loaded Forrest-Sherman with a displacement of only 4,050 tons. The target carried by the class destroyer."
As long as it’s artillery, Dr. Burr is a treasurer, and he wants large-caliber artillery, because it is bulky, it is usually carried on a warship. During the First World War, it was the battle of giant artillery, which made people look quite similar. Mighty and spectacular.
However, modern naval guns are different from the previous ones, they pursue lightness.
"This type of MK71 naval gun system includes a lightweight 203 mm barrel, turret, automatic bomb feeder, and control platform. It is a highly automated modern single-barreled naval gun system. If you compare it, the barrel of the MK71 naval gun The length is the same as that of the MK16 203mm naval gun equipped on the Des Moines class heavy cruiser, and both have a diameter of 55 times. However, the barrel weight of the MK71 is only about 9 tons, while the barrel weight of the MK16 reaches 17.14 tons."
In this comparison, you know how light it is.
"At the same time, this single-barreled naval gun uses a large number of aluminum alloys in the turret, and the weight of the entire turret rotating part is only 7.8 tons." Dr. Bull said: "For you, if you have this type of naval gun, you can Carried on your destroyer in active service."
If it wasn't because of President Carter, this guy had been clamoring for peace, cutting the army, and reducing military expenditures, otherwise this artillery would have been in service long ago.
Now that they have come to Han to help them realize the large-caliber naval guns, should they value themselves?
Dr. Bull looked at Qin Guan, and Qin Guan at this time was also thinking about Dr. Bull's proposal.
In modern naval battles, missiles are the mainstream, but naval guns have not been abandoned. If you look at all warships, you will have a naval gun at the bow, and you will know that this is the evergreen tree of shipborne weapons.
So, since naval guns are to be equipped, there is a problem of choosing the caliber of the naval guns. In the past, Han was mainly based on the system of the Xiong country, so the caliber of the naval guns was also based on the Xiong country. However, it soon fell into an outdated position, and it happened to be in the honeymoon period with the West, so naturally it aimed at the West.
At that time, the MK-45 127mm naval guns produced by the Eagle State and the 114mm naval guns of the Niu State were the choices, but at that time the tonnage of the Han Chinese destroyers and frigates was generally not large, so these naval guns seemed too heavy.
Therefore, after careful selection, Han Guo set his sights on the T100C compact single-barreled 100 mm naval gun developed by Ji Guo. This type of gun is light in weight and convenient for deployment on destroyer frigates. The maximum range can reach 17.5 kilometers. The maximum rate of fire is 90 rounds/min. The whole gun has a high degree of automation and excellent performance.
At that time, Han Guo had limited funds. A total of 2 single-barreled 100mm naval guns were purchased. One was installed on the "Siping" frigate and the other was disassembled for imitation.
But later, with the development of the Navy, this gun became tasteless. Compared with the 127mm gun, its range was seriously insufficient. Compared with the 76.2mm gun, its rate of fire was insufficient, so it was quickly eliminated. .
