However, compared to the implementation of the education agreement, the implementation is still stumbling in the implementation of aviation technology exchange. It's like the Soviets, who are very troublesome if they don't take advantage of it, always do something when fulfilling the agreement, and always have to rub some oil to be willing.

Except for the Lager III fighters in the agreement, which have been transferred to the second line of fighters in the Soviet Army, and the transfer is relatively happy, none of the other aspects are implemented happily. Either the timing of the delivery is totolara, or the quantity does not coincide with the content of the agreement.

As for the agreement on the exchange of aviation technology in the agreement, Yang Zhen was originally quite annoyed by the Soviets' refusal to provide the better-performing Yak-1 fighter as a temporary replacement. However, under the increasing pressure on the front line, and the British-made Hurricane fighters were really unable to shoulder the heavy responsibility, they finally chose to receive this batch of Lager-3 fighters as a transition.

There is no way to say that although the ground has entered a truce, everyone is licking their wounds and accumulating strength to prepare for the next bloody battle. But in the air, large and small air battles never subsided. Since the end of the battle, the entire Northeast and North China battlefields have formed a situation of cold war on the ground and hot war in the air.

In order to disarm the bases bombed by the Anti-Japanese Union, the Japanese army completely niptred the anti-Japanese air raids against Japan in the bud. As well as the complete solution of the northeast base area, the current ongoing large-scale industrial construction, to stop the pace of development of the Anti-United Nations, and to weaken the continuous combat capability of the Anti-United Nations.

After the Southeast Asian theater entered a period of stability, the Japanese army transferred almost most of the army aviation units deployed in the Pacific Ocean and returned to the Northeast and North China theaters, and the focus of the Northeast theater was the Northeast theater. The Japanese army deployed nearly half of its army aviation in South Manchuria and the Korean Peninsula.

At the same time, with the Japanese army aviation, the main forces were turned to the Chinese battlefield. The Japanese Kwantung Army, which felt that its waist pole had hardened again, constantly dispatched a large number of bombers to try to penetrate deep into the rear of the Anti-United Nations to destroy the bomber bases of the Anti-United Nations. Of course, there are also the oil fields and steel industry bases that have begun trial operation of the Anti-Union, as well as the railway lines in the rear.

Since the Anti-Japanese Alliance switched to the defense on all fronts, the fighting on the ground has cooled down. But over the entire Tohoku region, fierce air battles broke out almost every day. The number of troops invested by both sides has increased from a dozen or dozens at the beginning to hundreds at the end.

Moreover, with the strategic focus of the Japanese Army Aviation, it gradually began to shift to the Chinese battlefield. The number and number of new aircraft put into the Chinese battlefield by the Japanese Army are also constantly increasing. Not only the various models of the Japanese Army's Type 1 fighters were prioritized for the Northeast Theater. The latest Type II fighters were the first to be equipped with the North Korean Army and the Kwantung Army.

Compared with the previous several battles, although the Japanese army has invested in an improved model this time, it is also a familiar one after all. The Type 2 high-altitude and high-speed interceptor is the first time that the Anti-Union has fought with it. In the face of this kind of strange appearance because the engine is disproportionate to the body, the anti-union pilots gave him the nickname of a fat-headed fish.

The performance is completely different from the previous fighters of the Japanese Army, which pays more attention to the performance of aerial combat. The anti-coalition air force, which was caught off guard, suffered heavy losses in many air battles. In the past, Japanese aircraft, which focused on low- and medium-altitude combat performance, generally had poor high-altitude performance.

However, this kind of aircraft is quite different, not only has excellent high-altitude performance, but also has the fastest speed among Japanese aircraft. Its climb rate is also the fastest among Japan's active fighters. Although the fighting performance is a little worse, its speed is incomparable to that of previous Japanese fighters.

In the air battle and air defense operations, the Anti-United Nations faced the Hurricane fighter, which was already barely able to cope with the basic model of the fighter. It was really unable to compete with the Type 1 improved fighter jet, which was heavily invested by the Japanese army, and the Type 2 Zhong Kui fighter, which was later put into air combat.

Even if the British urgently provided a batch of Hurricane-2C fighters, they still could not compete with the Zhong Kui fighters and the Type 2 fighters. The Japanese army's rapid strategic transformation was expected by Yang Zhen. However, the strength of the army aviation he invested was something that Yang Zhen did not expect.

Originally, according to the tactics formulated by the Anti-Japanese Alliance, the Hurricane fighters, who were mainly responsible for Japanese bombers in air battles, were no match for such Japanese planes at all. I can't beat it, and I can't run a hurricane that is nearly 100 kilometers slower than the top speed of others.

The only thing that everyone has similar performance is that the legs of this kind of aircraft are not much longer than those of a hurricane. In terms of combat radius, everyone is 50 steps and 100 steps, and no one is better than anyone else. As the control area of the Anti-United Nations continues to expand, the front line is getting farther and farther away from the rear of the Anti-United Nations.

In addition, after the Japanese army aviation arrived in South Manchuria and Korea, it did not dare to deploy its combat planes too far forward because of the continuous tactical bombing of the Anti-Japanese Union. Therefore, although this kind of aircraft is the best fighter with high-altitude performance in the Japanese army so far, the time in the air has still become the biggest shortcoming of this kind of aircraft. The time in the air is short, and it is impossible to stay in the war zone for too long. It did not bring too heavy losses to the anti-United Nations air force.

But despite the fact that each air battle does not last long, this aircraft is not something that Hurricane fighters can fight against. Everyone is fighting at the same level, but their speed is almost a hundred kilometers faster. And the rate of climb and the maximum ceiling are not comparable to the Hurricane fighter.

Not to mention the old Type 2B, even the latest Type 2C is not an opponent at all. Because the biggest difference between these two types of aircraft, which use the same engine, is that they are equipped with different weapons. As for the performance, there is not much change, that is to say, the soup has basically been changed, but the dressing has not been changed.

In desperation, the anti-union can only reduce the original number to dispensable, and the maintenance is extremely difficult. Prepare to transfer to the reserve mothballed some of the remaining MiG-3 fighters, and invite them out of the mountain again. Take advantage of the excellent high-altitude performance of this aircraft to confront the Type II fighter.

In the case of fruitless negotiations with the Americans, Yang Zhen could only choose the Yak fighter as the main fighter in the subsequent struggle for air supremacy. Receiving this batch of Lag-3 fighters, as a transition before the arrival of the Yak-9, it competed with the Japanese for air supremacy in the low- and medium-altitude areas.

This batch of Lager-3 fighters, although the performance is not ideal. However, before the arrival of the new fighter promised by the Soviet Union, it could at least fight with the late Type 1 and the new Type 2 fighter put into service by the Japanese army. Of course, the confrontation with the Type II can only be at medium and low altitudes, and at high altitudes, this Lag-3 fighter is also not an opponent.

Shortly after the arrival of these Soviet-made fighters, a large-scale air battle broke out, which also made Yang Zhen feel glad that he chose to compromise at that time and did not continue to confront the Soviets. If it weren't for the outstanding performance of the Lag-3 fighters, I'm afraid that the air battle would have become a different result.

Before the arrival of this batch of Lage-3 fighters, the original main fighter of the Anti-United Nations, the P40B fighter, was no match for the Type 1 and Type 2 fighters. With comparable maximum level flight speeds, neither the rate of climb nor the dive performance can compete with this fighter. The only advantage was the density of firepower, and the rigidity of the fuselage was higher than that of the Japanese aircraft.

The original Hurricane and P-40 fighters were not only quite difficult to fight against the two new Japanese fighters, but also had a very high battle loss rate. It can be said that after these two new Japanese fighters were put into the battlefield, the air supremacy of the Anti-Japanese Union was greatly threatened.

The Japanese Army Air Force, which was heavily pressed on the border, completely destroyed several air bases in Jiamusi in order to completely destroy the Anti-Japanese Union. In early October, it changed its previous practice of dispatching in small groups and paid more attention to weakening the anti-United Nations fighter group. The method of large-scale cluster sorties and multiple batches of air raids was adopted.

During this air raid, the air force of the Kwantung Army was dispatched, and more than 120 bombers were dispatched in one go. Among them, in addition to the Type 97 medium bombers, these already familiar faces of the Anti-Japanese Union, the latest Type 100 heavy bombers were also dispatched. Moreover, this model is a little more advanced than the Type 97 bomber, and even accounts for nearly half of the Japanese bomber group.

Behind this batch of medium-sized bombers, there are more than 70 Type 99 dive bombers, Type 99 twin-engine light bombers, and Type 97 light bombers as the second bombing echelon. The main task of these dive bombers and light bombers was to attack the airfields where the anti-United Fighter Group was located.

The number of bombers it put into use accounted for almost two-thirds of the entire Japanese army aviation in the Chinese theater. All of the so-called heavy bomb planes were transferred from Southeast Asia and the Pacific theater. The Japanese army dispatched such a large group of planes at one time, not only for the first time since the July 7 Incident, but also for the first time since the outbreak of the Pacific War. The blood cost of the Japanese army is not small.

These bombers took off from Liaoyang and Mukden in South Manchuria and Seoul in North Korea, and under the cover of 62 Type 2 fighters and 36 Type 2 Zhong Kui fighters that were put into the battlefield for the first time, they attempted to carry out a large-scale bombing of the anti-United Nations air base on the front line of Jiamusi. The planes that bombed Japan and the factory area of the Anti-United Nations were completely destroyed on the ground.

In that air battle, almost all of the fighter groups of the air forces deployed in the northeast by the Anti-Japanese Union were engaged in air combat. Even the Hurricane-4 fighters that had just arrived, and the 24 Lag-3 fighters that had just completed conversion training, were all engaged in air combat.

Considering the difference in the performance of the aircraft, the Anti-United Nations adopted certain tactics in air combat. With the Hurricane 2B, under the protection of the only 17 remaining MiG-3 fighters, it was only responsible for attacking Japanese bombers. The MiG-3 fighters, which were launched in concert, were prepared at high altitude to attack the Type 2 fighters that the Japanese might attack.

There is no way to fight the Hurricane II fighter, no matter which model it is, it is not the opponent of the Type 2 Zhong Kui. The MiG-3 fighters, who were already old and cultivated in the Anti-Japanese Federation, but were re-invited to go out of the mountains to exert their residual heat, could be put on standby at high altitude to protect this kind of fighter that was supposed to protect others.

The Lag-3 fighters, the Hurricane-2C fighters, and the P-40 fighters, which were already small in number, met the escorted Japanese fighter group. The two armies fought the largest bloody aerial battle over the Sino-DPRK border and the Xinjing line since the formation of the Anti-United Nations Air Force.

It was only in this large-scale air battle that the anti-United Nations aviation forces shot down two-thirds of the Japanese heavy bombers, almost all the light bombers, and more than 80 Japanese escort fighters. However, although the entire battle plan of the Japanese army was ultimately thwarted, the anti-coalition air force itself suffered heavy losses.

In this air battle, which lasted for a whole day, 35 of the 40 Type 2C Hurricane fighters that took off to meet them were shot down in the air battle. More than 50 Hurricane-2B planes, which were tasked with attacking the Japanese bomber group, were shot down by more than 20 Japanese Type 2 fighters specially escorting the bomber group.
