Khimki in the Moscow region is a small city with a population of less than 30,000. Pen, fun, and www.biquge.info

This small city, in the eyes of ordinary people, is ordinary and backward, but in the eyes of Soviet Deputy Prime Minister Manturov, it seems extremely important.

On the morning of August 18, Manturov's car traveled along Leningradskaya Avenue in a northwesterly direction. He drove his ZIS-101M sports car through the wide Leningrad Avenue, unobstructed, until he left Moscow, where the speed slowed down.

Eventually, his sports car stopped next to a nondescript grove in Khimki. He chose to get off here not because "people have three urgencies". Dressed in a neat suit and wearing black-rimmed glasses, he doesn't look like a person who would pee on the side of the road.

Manturov walked through a nondescript path through this dense grove and saw a gray concrete building.

The four-storey concrete building looks unremarkable on the outside, not unlike an ordinary factory building. However, this unremarkable building turned out to be one of the most important military-industrial institutions of the Soviet Union - the 301 Design Bureau.

Seeing a young man coming from the forest, the guards guarding the design bureau immediately entered a "combat state". Judging by the young man's dress and walking posture, the guards at the gate thought that he was a newcomer.

As Manturov approached, the guards, dressed in neat uniforms, held their heads high and shouted to the approaching young man: "Comrade, who are you looking for?" ”

Manturov walked up to the guards and said politely and softly: "I'm looking for Comrade Lavochkin." ”

The guard responded, "What are you looking for him for?" This is a military place, if you are looking for him for personal matters, please wait here, I will report it, and he will come out to see you. ”

"It's business." Manturov replied.

"What business? Please show your ID! The guard asked aloud.

Without saying a word, Manturov took out his military ID and handed it to the guards.

Vladimir Fedorovich Manturov...... Position: Deputy People's Commissar of National Defense...... Rank: General! When he read this, the guard's heart suddenly fluttered. He never thought that the seemingly weak young man in a suit in front of him actually had the rank of general and was still the deputy minister of defense!

The guards returned their documents, immediately saluted a standard military salute, and shouted forcefully: "Welcome Comrade General to the 301 Design Bureau!" ”

"Is Comrade Berygin coming?" Manturov asked.

"Which Comrade Beregin?"

"Comrade Mikhail Yevgenyevich Berykin, designer of the UB machine gun. You say that, he probably didn't come. If he comes later, please take him to Comrade Lavochkin. Manturov's tone was as gentle as ever, but the content of his words was intimidating.

"Yes!"

"Can you take me to Comrade Lavochkin now?"

"Of course, Comrade General!"

Lavochkin's office is located on the third floor of a concrete building. The office is not very large, the walls are plastered with pictures of various fighter jets, and the desk is full of models of Lavochkin fighters.

"Comrade Manturov, I am very happy to meet you, may I ask you what you want me to do?"

Manturov looked at Lavockin, who was sitting at his desk and looking at the "Report on the Encounter with the New German Fighter", and said: "Comrade Lavochkin, I have come this time to discuss with you about the upgrade of the fighter. ”

"Fighter upgrades?"

"Yes," Manturov said, looking at the report in Lavockin's hand, "I think you should also know that the Germans have now developed a new type of fighter, which not so long ago entered the Belarusian battlefield.

This fighter has very good protection, as well as strong firepower, speed, performance and other aspects of performance are quite good, causing great trouble to our aircraft. ”

"Actually, just two weeks ago, our design bureau No. 301 received information about the German army's introduction of a new fighter. But at that time, we did not know anything about the performance of the new enemy aircraft, and it was not until yesterday that Comrade Malenkov sent someone to our design bureau a report on the performance of the enemy aircraft, and we did not know a little about this German fighter with the model Fw190. ”

"And what do you think we should do with this German aircraft?"

Lavochkin thought for a while, suddenly frowned, and said: "According to the content of the report, the Fw190 fighter is equipped with 2 machine guns, 4 cannons, and the firepower is very powerful, and the protection of the all-metal fuselage is also very strong. To counter this superior aircraft in terms of firepower and protection, we should increase the firepower of the La-7 fighter, but the question is, how? ”

"I have a solution," said Manturov's descendants, "and we can increase the number of 20-mm guns on the La-7 from two to three." In this way, although our firepower is still not as good as the Fw190, it is also a big improvement. ”

"Three doors?" As the designer of the La-7 fighter, Lavochkin is well aware of the performance parameters of this fighter. By the standards of the time, if the number of aviation guns was increased from two to three, I am afraid that there would be a lot of problems. "Comrade Manturov, if the number of cannons is increased to three, I am afraid that the performance of the aircraft will be affected."

Manturov responded: "The Schwark 20 mm cannons weigh 40 kilograms each, and if we increase the number of Schwacker 20 millimeter cannons to three, the weight of the aircraft's armament will increase to 120 kilograms, and the performance will inevitably suffer."

But now Comrade Berezin has developed a lighter 20-mm caliber aviation cannon. The weight of this cannon is only 25kg, and the combined weight of the three cannons is only 75kg, which is less than the weight of two Schwark cannons. ”

"Really? If you don't say it, I really don't know that Comrade Berezin has developed a lighter cannon. ”

"Yes, Comrade Lavochkin." "Comrade Berezin, on the basis of the UB machine gun, increased the caliber of the 12.7-mm machine gun to 20 mm to fire 20x99mm R shells from the ShVAK cannon," Manturov explained.

The performance of this cannon is almost exactly the same as that of the Schwark cannon, both in terms of rate of fire and muzzle velocity. But the weight was much lighter than the Schwark gun, only 25 kg. ”

Hearing this, a smile of joy suddenly appeared on Lavochkin's face. "If there really is a 25-kilogram 20 mm caliber cannon, let alone 3 cannons, even if it is 4 such cannons on the La-7 fighter, it will not be too much of a problem."

"I have already informed Comrade Berezin that he will come here in person later to explain to you the specific performance of the B-20 cannon and submit the design and test documents of this cannon for your reference."
