At noon, Beitangkou Shipyard was busy. More than a dozen new shipyards here are building cruisers, offshore patrol ships, trawlers, clipper transport ships, armed merchant ships, communication speedboats and other types of ships.
Now it is a shipyard mainly for civilian use. All military ships will be relocated to the Jeju Island base in the future. There, thirty docks are under construction and will be put into use by the end of the year. Now that these ships have been launched, the construction of warships has stopped.
Chief Engineer Chang Zhu came here to see the machine tools this time. The Naval Shipyard used some new machine tools that were transferred to them. These were obsolete old machine tools from the 1950s and 1960s, collected by idiots who collected scraps. Monkey hired some repair technicians and spent some time to repair it again.
Chang Zhu was the earliest master craftsman of Xinghe Iron Works, and he and Qi Laoliu were in the same group. Now he specializes in light weapons, while Qi Laoliu specializes in artillery.
Chang Zhu is thirty-six years old. At this age, he works during the day and goes to night school to learn science and engineering knowledge. He deeply felt that without this new knowledge, he would not be able to do his job.
The revolver is their latest achievement. As early as the end of last year, they made the flintlock revolver. But it's not safe, and the master didn't agree to mass production. I just made more than fifty tubes for experimentation. Later, the metal bullets of Lu Xiaozhou's team passed the test. The left wing suddenly came to life again.
After discussing with his team, Lu Xiaozhou's team sent a telegram to the master asking for permission to establish the project. The master finally set the caliber at 9 and gave it a strange name: Parabellum pistol bullet. Because it is difficult to pronounce, the ammunition team is generally called standard pistol ammunition.
Parabellum 9 pistol bullet, also known as 9 NATO standard pistol bullet. The bullet specifications are 919 special pistol bullets, which are the most commonly used military, police and civilian bullets in all countries in the modern world. More than 50 countries have adopted it. Beautiful country also finally adopted this ammunition in 1986.
Originally, Yang Fan was optimistic about the Mauser 7.63 pistol cartridge.
This bullet type is also awesome. The famous box gun uses this type of ammunition, which is powerful and has a long range. The shell gun is added with a gun box as the butt, and the effective range is greatly increased, up to 100 meters. The effective range of some shell guns with extended barrels can reach 150 meters.
During the Republic of China, the Dagu Shipyard produced a batch of independently developed carbine-style hull guns with extended barrels. Using a twenty-round magazine, when firing a single shot, the effective range can reach 150 meters. The rate of fire reaches 900 rounds per minute. It can also be equipped with a forty-round extended magazine. It can almost be used as a submachine gun.
In addition, the Type 50 submachine gun in the early days of the founding of the People's Republic of China. It is an imitation of Damao's Bobosha submachine gun that was produced most during World War II. This is the kind of ammunition used. However, what Da Mao introduced from Hans was 7.63, and the one they produced themselves was called 7.62. Although there are some slight differences, the two calibers can be used interchangeably.
Generally speaking, 9 is the mainstream for police, and 7.62 for military seems to be more suitable for getting up early. The main military use of pistols is to make bullets for submachine guns. Generally, pistols are of little use in the army.
Those equipped with pistols were all mid-level and senior officers. By the time they were hit, the entire army had basically been wiped out. The bad thing about pistols is that they are used by senior officers to commit suicide. After all, soldiers have their own honor, and many people do not want to be captured.
If the bullet jams at this time, the officer will definitely kill the designer and his whole family.
Yang Fan only approved the Balaberum bomb first. As for the Mauser bomb, he was still considering it. 9 is relatively easy.
Chang Zhu came here to see the machine tools, because the production of pistols requires very high precision. The biggest reason why revolvers are used now is that they have copied several pistols that Yang Fan provided drawings for. All jammed. On average, less than thirty rounds are guaranteed to jam. This is fatal on the battlefield.
At present, breech-loading rifled guns are all single-shot and have no magazine design. It’s because the magazine craftsmanship is not up to standard and jamming is a big problem. Yang Fan decided to mass-produce a batch of single-shot rifles first, and then work on the next generation after the magazine and magazine technology was passed.
Although these guns do not have magazines, they need to be fired and loaded. But the extractor hook is taken out, otherwise, after firing a round, you have to use a knife to remove the bullet
Once the shell is pried off, the soldier must shoot the designer's black gun. This is so fucking annoying.
Nowadays, breech-loading rifled guns can basically load one round, fire it out, and automatically eject the shell. The level at which the soldier manually loads the next round. There is no problem if the rate of fire reaches 15 rounds per minute. However, the flintlock rifle has just been in service for a year, so it would be a waste to change it now. So hundreds of thousands of them were produced, but they were kept in the warehouse and not distributed.
At noon, the food in the VIP building of the shipyard restaurant is very good, and it is close to the sea. Yellow croaker stewed with tofu, fried sea cucumber with green onions, charcoal grilled oysters, and braised large prawns. There is also excellent Jingcheng rice wine. Chang Zhu and the students he brought were very happy after eating.
Yang Fan bought 10,000 acres of wasteland in Beitangkou. The land here is extremely cheap, but it is all saline-alkali land and cannot grow crops. Yang Fan built a marine industrial park. Inside are factories that process seafood.
After eating, he took the students to the pier to eat and enjoy the sea breeze. Although Chang Zhu was taking a walk, she still couldn't let go of her work and was still thinking about it.
Chang Zhu planned to give both types of ammunition a try, and it would be best to get some matching guns. After all, he is very yearning for the follow-up automatic pistols and submachine guns planned by the master.
The master wrote back and specifically told him in detail the classification of future light weapons. Especially the difference between rifles, assault rifles, and submachine guns.
To put it simply, rifles use full-power bullets, and light machine guns also use rifles. The main modern ammunition is 7.62X51.
And sum up the experience and findings of World War I and World War II. Infantry battles mainly occur within 300 meters. For example, the effective range of the Mauser 98K is 800 meters, which is actually a waste. This distance is simply impossible for a sniper to shoot accurately. Heavy full-charge, full-power bullets reduce the amount of ammunition carried and increase the burden on soldiers.
The effective range of Xiaoguizi's Type 38 is 460 meters, the caliber is reduced to 6.5, it has less charge, less recoil, and more accurate shooting. The bullets are lighter and carry more ammunition. And the recoil is suitable for Asian people's physical condition. It is a design that is closer to the actual situation on the battlefield.
The reason why they did not develop assault rifles is because their island country lacks resources. A narrow thinking of saving resources has formed. They hate bullet-wasting submachine guns from top to bottom. There is simply no interest in assault rifles that can fire automatically.
Therefore, in the late period of World War II, the Germans took the lead in shortening the rifle bullet and created an intermediate bullet with the length of the full-power bullet of the handgun and the rifle.
This type of bullet is used by assault rifles. The effective range of this assault rifle is generally between 300-400 meters.
The submachine gun uses a pistol, which is the biggest feature of the submachine gun.
"Mr. Chang, look, what's wrong with that boat? It looks so miserable." A girl of seventeen or eighteen years old shouted. This girl's name is Li Zhuzhu. She was assigned to Chang Zhu's team after graduating from the academy last year.
Chang Zhu raised his head and looked up, only to see a black ship. The front of the entire roof seemed to have been chopped by a huge axe. There were several large holes and the steel plates were wrinkled. It looks so scary.
Moreover, there are many holes in the hull, which look like lotus pods.
The boat teetered ashore. The iron shed in the middle was deformed and stuck, and it could not be pushed or pulled. The people inside used fire axes and slashed hard, and then a strong man with gloves tore open a large piece. Just open the side door.
Many people walked down from inside. Many people were bandaged up like mummies.
A young man got off the gangplank covered in blood and looked unhappy, accompanied by a beautiful girl.
Chang Zhu walked over and called out: "Zhuzi, what's going on with you, why are you covered in blood? Are you okay?"
Zhuzi looked up and saw that it was Chang Zhu. He grinned and said, "Ah, Uncle Chang! Why do you always come to pick me up? I don't dare to be your charioteer."
Chang Zhu laughed angrily, and this lazy boy kicked him over, laughing and scolding: "Fuck you, I'm here to see the machine tool. What did you do?"
Zhuzi smiled bitterly and said: "It's okay, it's all other people's blood. I encountered a vicious dog blocking the road and got bitten by it."
