Today, the first update, ask for recommendations, ask for collections......

Today's Datong Armored Vehicle Factory, there is good news again, the first tank has been off the assembly line, is waiting for Zhang Yunfei's review, Zhang Yunfei heard the news, ecstatic, his dream tank has finally been manufactured.

Zhang Yunfei, who was in a good mood, called Political Commissar Fang Zheng, Deputy Division Commander Liu Dazhu, and Armored Brigade Commander Wu Youqing, and everyone drove to the armored vehicle factory on the outskirts of Datong.

At this time, the colorful flags at the door of the armored vehicle factory were fluttering, lively and extraordinary, the door was full of greeting people, everyone's face was full of energy, after the first armored car rolled off the assembly line, and through several months of hard work, the first tank was produced in full accordance with Zhang Yunfei's requirements.

The first tank produced, painted in this beautiful camouflage, quietly parked in front of the assembly workshop of the armored vehicle factory, covering an area of nearly ten acres, on the square, waiting for everyone's acceptance and review.

At the time of development, Zhang Yunfei provided everyone with technical requirements, which frightened many people, and even a large number of Jewish experts who participated in the development together had never seen such high requirements, but fortunately, Zhang Yunfei drew a clear schematic sketch according to his own memory, which was of great help to the development work.

After the development of the tank, the engineers and technicians of the armored vehicle factory were proud, dreaming that this tank would gallop on the battlefield and make outstanding contributions to the cause of the motherland's anti-Japanese war.

A few months ago, Zhang Yunfei also gave a special order to transfer a little devil's tank from the training tank of the armored brigade for everyone's reference and research.

While everyone was waiting, Zhang Yunfei's motorcade gradually approached, and when they saw Zhang Yunfei and other high-level leaders of the 136th Division coming, the crowd at the door broke out into happy cheers.

As soon as Zhang Yunfei's off-road vehicle stopped steadily, the director of the armored vehicle factory walked forward quickly, opened Zhang Yunfei's door, and said respectfully: "Welcome to the chief." ”

Zhang Yunfei nodded slightly, quickly got out of the car, waved to the crowd at the door, and then everyone hugged Zhang Yunfei and came to the front of the first tank together, looking at this tank, Zhang Yunfei was also very happy in his heart, and said loudly to everyone: "Comrades, I am very proud and happy to see this tank, this is the first tank produced in our base, and it is also the first tank produced in Chinese history, thank you very much, In particular, the vast number of workers and engineering and technical personnel who are fighting day and night in the front line of development and production. ”

After speaking, Zhang Yunfei bowed to everyone emotionally, and everyone was full of excitement and gratitude when they saw Zhang Yunfei's actions, and felt that their hard work in the past few months was completely worth it.

After bowing, Zhang Yunfei praised everyone again, and everyone felt sweeter than honey, Zhang Yunfei finished talking to everyone, and said to the director of the armored vehicle factory next to him: "Director Ma, tell you about the surname and parameters of this tank." ”

The director of the armored vehicle factory looked proud and said happily to everyone: "Hello everyone, I will give a detailed introduction to the surname and technical parameters of this tank we produce.

The tank weighs 32 tons, has a crew of 4 people, the main armament is a 75 mm smoothbore gun, the effective range is 5,000 meters, the secondary weapon is a 12.7 mm high-level dual-purpose machine gun, the width of the vehicle is 3 meters, the height of the vehicle is 2.5 meters, the water-cooled diesel engine, the power is 360 kilowatts, the maximum speed is 55 kilometers per hour, the maximum range is 450 kilometers, the height of the obstacle is 0.75 meters, the width of the trench is 2.49 meters, the climbing is 30 degrees, and the armor thickness is 18-60 mm.

The tank is equipped with inter-vehicle radio communication equipment and has strong cooperative combat capabilities; The body armor is all 45 mm thick, which is much thicker than the tank armor of the little devils, and the front armor has a 32-degree bevel, and the sides also have 49 degrees. The turret was a cast hexagonal type, the frontal armor was 60 mm thick, the sides were also 45 mm, and the bevel of the body extended to the turret.

Bevel armor has two advantages: first, it is easy to bounce off after a shell hits (i.e., "ricochet"), and its power is greatly reduced; Secondly, according to the triangular principle, after a horizontally fired shell hits the inclined armor, the thickness of the steel plate that needs to pass through it is equivalent to the hypotenuse of the triangle, so the frontal armor of this tank with a thickness of 45 mm and a bevel angle of 32 degrees is equivalent to 90 mm, and the side armor of the 49-degree bevel is equivalent to 54 mm.

Such frontal armor, as far as I know, has not yet been able to penetrate the armor of our tanks at a distance of 500 meters, not even the current German tanks.

In addition, our tank can reserve 70 rounds of ammunition, and can also fire armor-piercing, high-explosive and armor-piercing shells, in addition to strong battlefield survivability, it also has excellent attack power. ”

The director of the armored vehicle factory, Ma Factory, was there to tell the story, introducing the surname and parameters of the tank in an orderly manner, and the political commissar Fang Zheng and deputy division commander Liu Dazhu next to him, listening to these introductions, his face was full of surprise, and he felt like he was in a dream, only Zhang Yunfei was calm.

Wu Youqing, the commander of the armored brigade next to him, listened to the introduction of the director of the Ma factory, and his eyes lit up, if there is such a tank to equip his own troops, it is too exciting, too exciting, too exciting, he used to train his own armored brigade, and used more than a dozen tanks of the little devils, and he usually treats these tanks like babies.

Director Ma introduced it for a long time before he could explain the surname of the tank clearly, and after Director Ma's words were finished for a long time, everyone came back to their senses, and suddenly thundered with joy and thunder, and resounded with long-lasting applause.

The applause stopped for a long time, and seeing that Zhang Yunfei was very happy, Director Ma took the opportunity to ask Zhang Yunfei: "Chief, our tank doesn't have a name yet?" It's better to give it a name today. ”

Zhang Yunfei pondered for a moment, and then said: "This year is 1939, our tank is called the Type 39 tank, and the armored personnel carrier produced before is also called the Type 39 armored personnel carrier. ”

"Well, great, our tanks, our armored vehicles have their own names." Director Ma also said happily.

Zhang Yunfei did not name the tanks as majestic names such as Tiger tanks or Leopard tanks, on the one hand, considering that more advanced tanks would appear in the future, and it would be very convenient to name those tanks by year in the future; On the other hand, naming by year is also in line with the international trend.
