Lin Jun finally understood why so many aircraft designers later won the "Sickle and Hammer" Gold Medal (the Socialist Labor Hero Medal, which is awarded to the Socialist Labor Hero at the same level as the Gold Star Medal, and the winners are generally non-front-line soldiers and civilians), this aircraft is not built by everyone!

On the first day of arriving at the Central Aircraft Design Bureau in the northwestern suburbs of Moscow, it took only five minutes for chief designer Nikolai • and Polikarpov to dispel the idea of lengthening the rear fuselage of the I-16. Pen? Interesting? Pavilion wWw. ｂiquge。 infoBecause if it is modified, it is not only necessary to re-conduct the pneumatic experiment, but also to carry out a reborn design of the whole machine to ensure that the aerodynamics are reasonable, and the workload can catch up with the redesign of a model.

While Lin Jun was devastated by this, Polykarpov also affirmed his idea of increasing the firepower of the aircraft and improving the cockpit canopy, because he also meant it. Moreover, when designing the I-16, Polikarpov already had a premonition that the power of the four improved 7.62-mm ПВ-1 machine guns would be insufficient, leaving room for weight changes in the load for the later installation of larger-caliber weapons, which would not have much negative impact on the flight qualities of the aircraft. The maximum speed of the I-16 has exceeded 450 km/h, and the powerful airflow brought by the semi-open cockpit will not only damage the pilot's health, but even have a certain impact on the pilot's combat, which the chief designer is also very aware of.

In the following month, Lin Jun assisted Polikarpov in designing the cockpit of the I-16, increasing the original front windshield by 10 centimeters, adding a front and rear push-pull curved hatch, and eliminating the small windshield at the rear. In this way, as long as the newly added hatch canopy is pushed forward and closed and locked, the cockpit of the I-16 is isolated from the outside airflow, and because the height of the canopy is slightly increased, it will basically not affect the pilot's line of sight. If the pilot pokes his head out of the cockpit in order to better observe the situation during the flight, he only needs to push the hatch cover back, which is very convenient.

In terms of firepower improvement, Polikarpov was more straightforward. He knew very well about the 12.7 mm "ШВКА" aviation machine gun that Lin Jun had chosen, and although it was powerful, it had the problem of low reliability. Polykarpov directly chose the newly developed 20-mm "Schwark" ШВКА cannon, which was more powerful, had good reliability, and was acceptable in terms of weight.

The first improved I-16 was launched in the workshop a month later. On the whole, all parties were happy about the improvement: there was very little room for improvement in the manufacturing process, and the I-16 was originally produced in large quantities in early 1935, which only set back the start of production of the aircraft by less than a month, which was acceptable to the aircraft production units. As for the Kremlin, the original understanding of fighter planes was that the I-16 attacked the enemy's aircraft group, killed the enemy in one shot, and installed high-powered aerial guns, which made them even more satisfied. The 20-mm Schwark ШВКА cannon was definitely a powerful cannon at that time, and only 2-3 hits were needed to destroy the structure of enemy aircraft.

The improved I-16 originally retained two ПВ-1 machine guns on the outside, the rate of fire of 750 rounds per minute and the reserve of 750 rounds per round allowed the aircraft to retain the ability to fight for a long time, and the 20-mm "Schwark" ШВКА cannon had 120 rounds per spare ammunition, and the total weight of the fully loaded aircraft was only 60 kg more than the original, which was within the allowable range of the Porykarpov design. If necessary, the aircraft can also carry a 200-kilogram bomb in the belly of the aircraft, which can be used as a light dive bomber.

Lin Jun volunteered to be a test pilot, and exchanged piloting improved and unimproved models with the chief test pilot of the Central Aircraft Design Bureau under full load, and conducted dozens of aerial combat exercises, which proved that the improved model could completely compete with the original design in terms of maneuverability. And when it came to the experimental stage of attacking ground targets, the enormous power of the 20-mm Schwark ШВКА cannon stunned those who took part in the tests! The combination of two armor-piercing incendiary shells and one anti-personnel incendiary shell turned the old MS-1 tank as a target into a pile of scrap metal!

Lin Jun directly handed over the report on the damage of the improved I-16 attack on ground targets to Stalin, which made Stalin feel very troubled.

The next day, several new T-26 (33) light tanks, BT-2 fast tanks, T-28 three-turret medium tanks, and the latest T-35 multi-turret heavy tanks were pulled to the range for air attack fire tests.

Stalin, Kalinin, Molotov, Voroshilov, Yezhov, Yagoda, and Zhdanov all inspected the shooting range on the day of the test.

Lin Jun personally drove the plane into the air, attacked three times at an attack distance of 500-250 meters, and used up all the ammunition, and the attack result made all the important people present break out in a cold sweat!

The T-26 (33) light tanks and BT-2 fast tanks lined up in the target area were completely reimbursed, and not only the top and rear of the tanks were pierced by armor-piercing shells, but even the frontal armor was penetrated by 20-mm armor-piercing shells. Except for the frontal armor that blocked four-fifths of the armor-piercing shells, the T-28 three-turret medium tank was completely unable to block the attack of 20-mm armor-piercing shells. The 35 mm frontal armor of the T-35 multi-turret heavy tank completely blocked the attack, but the rest of the tank was smashed into a sieve! And all the dummies placed near the tank were also torn to pieces by machine gun bullets and shell fragments. You must know that the armor-piercing incendiary shells fired by the 20-mm "Schwark" ШВКА cannon can penetrate the standard armor of 25 mm at a standard attack distance of 300 meters, while the armor of the T-26 (33) light tank and the BT-2 fast tank is only 20 mm at its thickest point, and even the frontal armor of the T-28 is only a pitiful 25 mm. Including the 50-ton T-35, the rear and side armor of all tanks is less than 20 mm, and in many places only 10-15 mm.

In the view of the members of the Central Executive Committee, it was understandable that the T-26 light tank and the BT-2 fast tank were destroyed under such an attack, because their combat objectives did not require protection against high-powered artillery shells. However, the T-28 and T-35 multi-turret heavy tanks, which were designed to target the "Land Cruiser," were all hit by 20 mm armor-piercing shells, and if they were hit by a larger caliber anti-tank gun on the ground, they would have no chance of survival.

This is a magnitude 30 earthquake of Soviet tank design and land tactical thinking in the 9s! At that time, the Soviet Union and the Western industrial powers believed that tanks should have a large number of guns and thick armor like cruisers at sea, so there were "land cruisers" with more than one turret - multi-turret tanks. And this erroneous thinking also allowed the USSR to waste too much time and resources in the thirties. This test completely destroyed the confidence and hope of the Soviet leadership in the multi-turret tank, and the development of the Soviet tank industry took a big turn on that day.

Lin Jun was very satisfied with the effect of his "performance", in fact, the initial test of attacking ground targets was added by himself, and according to reason, the combat purpose of the Yi-16 did not need to be tested by machine guns and machine guns to attack ground targets.

The next day, Lin Jun handed over to Stalin's office a document "on the direction of the development of tank weapons of our army" that had been prepared for a long time.

The most important points of the report are:

1. A new single-turret tank designed with frontal armor that can resist 76.2mm anti-tank gun attacks at a long distance.

2. The new tank should be more reasonable and average in terms of mobility, firepower and defense.

3. Simple structure, good reliability, suitable for mass production of equipment.

In the report, Lin Jun also listed some technical data of the T-34 tank that he knew for reference.

After an emergency meeting of the Central Executive Committee the day before, Stalin, having received Lin Jun's report, once again convened an enlarged meeting of the Central Executive Committee. The meeting was attended not only by members of the Central Executive Committee, but also by more than 40 generals of all branches of the Red Army, as well as by all the tank, aircraft and ship design specialists in Moscow.

"We need to take a good look at our operational doctrine! You have all read Comrade Andrei's report, if it were not for the tests and this report requested by Comrade Andrei yesterday, how much time and resources would we have wasted on the construction of the army! We, the Red Army, will have to suffer unimaginably huge losses in battles with the enemy! This requires us to start thinking about our operational theory anew and turn the building of the army in the right direction! ”

Stalin was very excited today.

"Comrades, before the meeting, Comrade Andrei and I discussed some ideas on the construction of the various branches of the Red Army, especially the ideas for the construction of the Air Force and Navy. All the comrades here, don't think that the opinion of a young officer is nothing, if you listen to Comrade Andrei's advice, you will all know how wrong our thinking was in the past! Well, now it is up to Comrade Andrei to express his proposals, and everyone present here must make a detailed record! Also, if you have comments and questions, you can put them forward on the spot, and Comrade Andrei will answer them. ”

In the morning, Stalin had already learned how powerful this Andrei was! For example, at that time, he had a different understanding of the army's opinions on submachine guns, and as a result, Lin Jun's explanation convinced the supreme commander.

"Your heads will be washed, too!" This is what Stalin thought when he sat back in his seat,

In the next hour or so, Lin Jun expounded his opinions on army building in a general manner. In the army, Lin Jun proposed to study a new type of tank at the same time, but also proposed to study a large number of equipment vehicle radios to enhance the tank's ability to communicate during combat (because the radio penetration rate of Soviet tanks at that time was terrible, and a lot of mutual communication relied on flag language). In terms of infantry equipment, Lin Jun proposed the need to equip a large number of submachine guns - this suggestion was immediately met with questions and different opinions from several "giants" on the army side: a large number of submachine guns not only consume bullets, but also submachine guns are ineffective at distances above 300 meters.

Lin Jun shot back: "What is the annual bullet production volume of our country? What is the usual consumption of the troops? What is the production potential of military factories in the wartime production system? Also What is our inventory? With some external circumstances that I am aware of, the existing ammunition production and production potential are fully sufficient for the needs of the troops. Of course, this aspect needs to be answered by the responsible comrades of the military production. Speaking of this, Stalin, who was sitting firmly in the Diaoyutai over there, asked the people of the General Logistics Department of the Red Army to answer the question, but the poor comrade could not answer at all, but said that it should be able to meet the general needs. This made Stalin a little angry, and ordered him to write a detailed report when he returned.

"Regarding the fact that submachine guns are not effective at distances above 300 meters, I don't think there is much impact on combat. Because submachine guns are now mass-produced, they will be equipped with about one-third of the soldiers of the front-line infantry units within five years, and the rest of the soldiers will be equipped with our high-power rifles and machine guns, which can meet the requirements of long-range fire. And at close range, a submachine gun in the hands of a fighter will inflict great damage on the enemy. Most importantly, our current operational theory is based on the mechanized offensive of the large corps, not on the positional trench warfare of the First World War. On the basis of this theory, our infantry fought with the support of tanks, or more precisely, with tanks, to clear out the remnants of the enemy, but also to ensure that the tanks were not threatened by local infantry. Under this premise, our infantry is fighting the enemy at a relatively close distance, and what is needed is powerful close-range firepower, and the effective range of the submachine gun of about 200 meters is enough to meet the requirements. On this point, I think the Army comrades present here should know better than I do. ”

Lin Jun is very confident because this is the truth.

Although the army generals present still need time to digest Lin Jun's innovative opinions, they have begun to accept them. In particular, one of the "big guys" in the army, Semyon•Mikhainovich•Bujonny, first affirmed Lin Jun's suggestion, which gave Lin Jun's theory another strong supporter.

When it comes to the construction of the Air Force, Lin Jun only said that while producing the I-16 and I-15 fighters, it is necessary to design fighters that are faster, better, and have outstanding maneuverability and firepower. Because there is no actual combat test and the comparison of the new aircraft of various countries that will appear in the next year or two, there is no conclusive theoretical basis, Lin Jun can only say this.

As for the navy, Lin Jun proposed to vigorously study aircraft carriers when national strength and technology are possible, and also to carry out research on new submarines, and not only focus on battleships represented by "big ships and huge guns."

This proposal was unanimously opposed by the Navy. They had no opinion on the development and construction of submarines, but the naval combat theories of the great powers in the 30s were based on "big ships and huge guns."

"Comrades in the Navy, I could not get you to agree with me at the meeting. In my opinion, the sea in the future will belong to the aircraft carrier group. Of course, due to the aircraft carrier itself, we also need a certain number of escort ships, and in the current technical situation, we also need strong artillery support from large ships during landing operations. I asked Comrade Stalin and the comrades of the Central Executive Committee for permission to conduct a confrontation exercise in the Barents Sea between torpedo planes, dive bombers, and a fleet consisting mainly of battleships, with me in command of the air force. I think the facts will tell you everything, and the powerful ocean-going aviation will determine the ownership of sea supremacy. ”

"Alright, my suggestion is described."

At this time Stalin stood up: "Comrades, I think that your mind has just experienced an earthquake of magnitude 9. This morning, I behave and think the same way you are now. We must attach importance to the problems mentioned by Comrade Andrei and do concrete and practical work. I approved the confrontation exercise, and I will personally observe the exercise. ”

Speaking of this, Stalin paused, "Although the correctness of Comrade Andrei's proposal on the Navy has not yet been confirmed, other proposals have made a great contribution to the Soviets and to the Red Army. I propose that Comrade Andrei be promoted to the rank of lieutenant colonel and that he be again awarded the Order of Lenin, the Order of the Red Banner and the Order of the Red Star. I now invite all the comrades present at the meeting to vote. ”

Stalin spoke, who would disagree? Besides, everyone was already convinced by Lin Jun's words just now, and knew the importance of these suggestions.

Five minutes later, Stalin personally changed Lin Jun's rank to that of lieutenant colonel, adding to his chest the Order of Lenin, the Order of the Red Banner, and the Order of the Red Star.
