At noon, the Beitangkou Shipyard was busy. More than a dozen new shipyards here were building cruisers, offshore patrol ships, trawlers, clipper transport ships, armed merchant ships, communication clippers and other ship types.
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 shipyards are being built and will be put into use by the end of the year. Now that these ships are launched, the number of warships
Construction 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 the naval shipyard. These are old machine tools from the 1950s and 1960s that were eliminated and collected by idiots. The monkeys hired some repairs.
The technician spent some time repairing it.
Chang Zhu was the earliest master craftsman of Xinghe Iron Works. He and Qi Laoliu were in the same group. Now he specializes in light weapons, while Qi Laoliu specializes in artillery.
Chang Zhu is already 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 feels that without this new knowledge, he will not be able to do his job.
The revolver is their latest achievement. As early as the end of last year, they had made a flintlock revolver. But it was not safe, and the master did not agree to mass production. They only made more than fifty of them for experimentation. Later, Lu Xiaozhou's team
The metal bullet passed the test. The left wing suddenly regained its vitality.
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 decided on the caliber as 9mm, and also gave it a strange name, called Parabellum pistol bullet. Because it was difficult to pronounce, the ammunition team
Generally called standard pistol ammunition.
Parabellum 9mm pistol bullet, also known as 9mm NATO standard pistol bullet. The bullet specification is 9x19mm special pistol bullet. It is the most used military, police and civilian ammunition in the modern world. It is used by more than 50 countries. Beautiful country
In 1986, this ammunition was finally adopted.
Yang Fan was originally optimistic about the Mauser 7.63mm pistol cartridge.
This type of ammunition is also very powerful. 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. Some shell guns with extended barrels are effective
The range can reach 150 meters.
During the Republic of China, the Dagu Shipyard produced a batch of independently developed carbine-style shell guns with extended barrels. Using a twenty-round magazine, when firing a single shot, the effective range could reach 150 meters. The rate of fire reached 900 rounds.
per minute. It can also be equipped with an extended magazine of forty rounds. 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 was a copy of Da Mao's Bobosha submachine gun that was produced most during World War II. It used this kind of ammunition. However, Da Mao introduced 7.63mm from Hans, and the one they produced themselves was called 7.62mm.
.Although there are some slight differences, the two calibers can be used interchangeably.
Generally speaking, 9mm is the mainstream for police use, and 7.62 for military use seems to be more suitable early. The main military use of pistol bullets is to make bullets for submachine guns. Generally, pistols have no big use in the military.
Those equipped with pistols are all mid-level and senior officers. When they hit them, the entire army was basically wiped out. Pistols are not good-sounding, but they are used by senior officers to commit suicide. After all, soldiers have their own honor, and many people do not
Willing 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 Parabellum bullet first. As for the Mauser bullet, he is still considering it. 9mm is relatively easy.
Chang Zhu came here this time to see the machine tools, because the production of pistols requires very high precision. The biggest reason why they use revolvers now is that they have copied several pistols that Yang Fan provided with the drawings. All of them jammed. The average is less than
Thirty rounds are bound to jam. This is fatal on the battlefield.
At present, breech-loading rifled guns are single-shot and do not have a designed magazine. This is because the magazine process is not up to par, and jamming is a big problem. Yang Fan decided to mass-produce a batch of single-shot rifles first, and wait for the magazine magazine process
After passing the test, we are working on the next generation.
Although this batch of guns does not have a magazine, it requires one round to be fired and one round loaded. However, the extractor hook has been removed. Otherwise, after firing one round, you have to use a knife to pry off the cartridge case. As a soldier, you must shoot the designer's gun.
Black guns are not allowed. This is so annoying.
Nowadays, breech-loading rifled guns can basically load one round, fire it out, and automatically eject the shell. The soldiers can manually load the next round. There is still no problem with a rate of fire of 15 rounds per minute. However, the flintlock rifle has just
It has been in the field for a year, and it would be too wasteful to change the equipment now. So hundreds of thousands of them were produced and are sitting in the warehouse without being distributed.
At noon, the food in the VIP building of the shipyard restaurant was very good. It is close to the sea. Braised yellow croaker tofu, fried sea cucumbers with green onions, charcoal grilled oysters, and braised large prawns in oil. There was also good Beijing rice wine. Chang Zhu and his wife ate.
The students who came were very happy.
Yang Fan bought 10,000 acres of wasteland in Beitangkou. The land price here is super cheap, and it is all saline-alkali land, so crops cannot be grown. Yang Fan built a marine industrial park. It is full of 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, he still couldn't let go of his 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 was very keen on the follow-up automatic pistols and submachine guns planned by the master.
The master wrote back and specifically explained to him in detail the classification of light weapons in the future. In particular, the differences between rifles, assault rifles, and submachine guns.
To put it simply, rifles use full-power bullets, and light machine guns also use rifle bullets. In modern times, they mainly use 7.62X51mm bullets.
Summarizing the experience of World War I and World War II, we found that infantry battles mainly occur within 300 meters. For example, the effective range of Mauser 98K is 800 meters, which is actually a waste. This distance is not accurate for snipers. The 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 6.5mm, it has less charge, less recoil, and more accurate shooting. The bullet is lighter and has a larger carrying capacity. And the recoil is suitable for the physical condition of Asians. It is closer to the battlefield.
Design for actual situations.
The reason why they did not develop an assault rifle is because their island country is short of resources and has formed a narrow resource-saving mentality. From top to bottom, they hate submachine guns that waste bullets. They are not even interested in assault rifles that can shoot automatically.
Therefore, at the end of World War II, the Germans took the lead in shortening rifle bullets and created an intermediate bullet with the length of a pistol bullet and a full-power rifle bullet.
This type of bullet is used by an assault rifle. The effective range of this type of assault rifle is generally between 300-400 meters.
Submachine guns use pistol bullets, which is the biggest feature of submachine guns.
"Mr. Chang, look, what's wrong with that boat? It looks so miserable." A girl of 17 or 18 years old shouted. This girl's name is Li Zhuzhu. She graduated from the academy last year and was assigned to Chang Zhu's team.
Chang Zhu looked up and saw a black ship. The front of the entire roof seemed to have been chopped down by a huge axe. There were several big holes and the steel plates were wrinkled. It looked so scary.
Moreover, there are many holes in the hull of the boat, which look like lotus pods.
The boat staggered to the shore. The iron shed in the middle was deformed and stuck, and 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 piece of it.
It's a big piece to open the side door.
Many people walked out of it. Many of them were bandaged like mummies.
A young man got off the gangplank with blood all over his body and a look of displeasure on his face, accompanied by a beautiful girl.
Chang Zhu walked over and called out: "Zhuzi, what's going on with you kid? 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 did you come to pick me up? I don't dare to be your chariot."
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 met a vicious dog blocking the road and got bitten by it."
