In fact, before the outbreak of World War II, the Germans already knew about the existence of the Daodao radar, and one of their intelligence officers successfully infiltrated the British Army and became an army staff officer. The intelligence officer named Glenn sent a lot of information to Germany, including radar intelligence, and he even sent a large number of drawings for the manufacture of "Lindemann's radar" to Germany.

Among the advanced technologies used in the Second World War, the role of radar may not be overstated. Britain and the United States were the direct beneficiaries of this technique, and Germany and Japan were able to acquire it before World War II, but their polities destroyed it.

At that time, Germany was a country with "one leader, one doctrine, and one political party," and the Führer had to decide what weapons could be put on the road, especially the weapons that cost a lot of money. Although the German military was infinitely interested in radar, because it was only a defensive weapon, it seriously deviated from Führer Hitler's "blitzkrieg" idea of attacking only, so no one dared to argue with Hitler on the issue of developing radar. It was not until 1940 that Germany began to develop the "Lindemann radar" based on Glenn's intelligence, but it was too late, because there was still a long process from the development of the radar to production and application.

So far, in addition to Chen Feng, the crossing man, the country that used radar for the first time in World War II was still the United Kingdom, and the specific battle was the Battle of Great Britain.

Although the Germans were extremely tough in the wars throughout Northern Europe and Western Europe, especially their sophisticated weapons and equipment made Britain and France and other countries suffer, it is undeniable. They lagged far behind the British in the development and use of such electronic devices. As the German ace pilot Adolf. As Garland later remarked, "We realized that the Royal Fighter Squadron must be under the control of some new device on the ground, for we heard the order to command the Spitfire and Hurricane aircraft to fight the German fleet with great skill and accuracy." This radar and its control over fighters surprised us, and it was a very painful one. But we can't do anything about it, we can't blow it up. "It can be said that the air battle of Great Britain, on which Hitler had high hopes, can be said to have been defeated by the secret weapon of the British army - radar.

Even the powerful Germany has suffered a big loss in the face of the artifact of radar, not to mention the Soviet Union, which has always attached great importance to the renewal of weapons and equipment, so they do not know at all that Chen Feng's department has long been equipped with advanced early warning radar, and all their actions that they think are hidden are like open fire in front of Chen Feng's department.

This time, the Northern Air Force did not intend to ambush the remnants of the Ninth Army of the Soviet Air Force, but when the 2nd Fighter Brigade took to the air to prepare for an air attack on Ulaanbaatar, the plane took off less than half an hour. There was an unusual reaction on the early warning radar. Liu Nijia and others, who got the news, immediately judged that it was the Soviet Air Force that was preparing to go south to bomb the guard division. Looking at the number of fighters, it should be more than two hundred.

For this reason, Liu Nijia immediately ordered the Second Fighter Brigade to send half of its escort fighters to set up an ambush in the direction of Ergen, and make sure to completely annihilate those Soviet fighters.

At this time, the only remaining heavy bomber brigade of the Soviet Air Force's Ninth Army, as well as 72 Iraq-16 fighters, were on a bombing mission in Ergen, which had been devastated by China's Northern Air Force in the past week. The entire group army originally had more than 1,200 fighters, but now there are less than 300 left. Of its more than 700 main combat I-16 fighters, less than 100 remained. The main battle bombers were even more damaged, leaving only the only TB-3 heavy bomber brigade that was not easily used, and as for those reconnaissance planes and transport planes, there were only about 100 left.

In order to complete this air raid mission. Zhukov also sent the only bomber brigade in his hands to Lu, but he did not expect that the fighters were ambushed by the Northern Air Force before they reached Ergen.

Take bombers as an example, there are only two kinds of bombers in the whole army, one is the B10 medium-range bomber made in the United States, and the other is the 47 strategic bomber, and the strategic bomber is one of the most important military secrets of the entire Northern Air Force, so the fighter is not parked at the same airfield in peacetime, and they have not cooperated with each other, so when the pilots of the second fighter brigade saw the Soviet heavy bombers, they were completely stunned.

In the eyes of all pilots, the TB-3 heavy bomber with a wingspan of 22.6 meters, a length of 16.4 meters, a height of 3.4 meters, and a wing area of 56.7 square meters is too large. All the pilots rushed to these behemoths like they had been beaten with blood, and there was nothing more gratifying for a fighter pilot than encountering bombers and transport planes, and what a glorious glory it was to shoot down such a behemoth, everyone went crazy.

The TB-3 heavy bomber is indeed huge, but its performance is not very strong, it is an old aircraft developed since 1930, straight wings, fixed landing gear, wing skin is lacquered cloth, fuselage skin is corrugated aluminum plate. Although old, it has an important role in the history of the Soviet Air Force. On March 23, 1932, the Revolutionary Military Council of the USSR adopted the Principles for the Organization of the Air Force of the Workers' and Peasants' Red Army, emphasizing the need to create a powerful heavy bombing regiment. In 1933, the Soviet Union began to form a long-range aviation corps, and by 1935 it had 400 TB-3s. In May 1938, three special mission aviation armies were established, each of which consisted of two heavy bomber aviation brigades, each with 150-170 TB-3 aircraft. Become the largest heavy bomber unit in the world. But these behemoths are simply weak in front of the two major aerial artifacts of the Northern Air Force, like fat sheep waiting to be slaughtered.

The ambush lasted for almost an hour, and more than 160 of the more than 230 Soviet fighters that came to attack were shot down, and all the rest fled the battlefield in an emergency. I have to admire the battlefield survivability of the TB-3 fighter, its huge body gives it a strong vitality, although the combat ability of the J-series fighter is very strong, but due to the limited ammunition carried, and the pilots are also novices who have participated in the war less than 5 times, they are not very familiar with this new fighter, so there is such a funny scene on the battlefield: a huge TB-3 heavy bomber fled in a hurry with a huge body, and a dexterous J-series fighter behind him intercepted everywhere, Although all the ammunition fired by the J-series fighters fell on the fuselage of the TB-3 heavy bomber, this huge fighter still continued to fly forward as if nothing had happened.

It is indeed not an easy task to shoot down such a behemoth, unless it can hit the vital part of the fighter plane at once. Therefore, although the Soviet Air Force was taken by surprise this time, it did not completely annihilate the Soviet bomber group.

When the Northern Air Force ambushed the Soviet heavy bomber group, Zhukov, who received a report from the front, was shocked and immediately ordered another aviation division equipped with new fighters to take off and urgently go to Ergen to reinforce the heavy bomber group.

However, not long after the fighter plane took off, Zhukov received a message from the defenders of Zonmod, just five minutes ago, the air defense observation post in the south called that a large number of fighters had just crossed their heads and were coming towards Zonmod, and according to their contact with the front-line aviation, it was not them who had returned, but the Chinese Air Force had come to retaliate.

Zhukov suddenly felt that one head was two big, the matter on Ergen's side had not been resolved, and there was a new enemy situation here, and the actions of the Chinese were too big.

There was no way, Zhukov had to order the 9th Aviation Division of the 10th Army, which went to reinforce Ergen, to immediately go to Zonmod, and at the same time ordered the defenders of Zonmod to immediately prepare for air defense, and all anti-aircraft weapons entered the position, stunned by the attack of the Chinese Air Force.

Zhukov was very confident in the air defense operations in the Zonmod direction, and his confidence came from the powerful performance of the new fighters; he did not come from the aviation unit, nor did he serve in the Air Force, and he was not very clear about the advantages and disadvantages of the performance of the fighters, but he knew that Comrade Stalin trusted and loved this new fighter named the MiG-3. It can be said that this new fighter is the highest industrial achievement of the Soviet Union at present, and of course, it is also the most powerful fighter of the Soviet Union, there is no one.

In fact, this fighter is indeed very good, although today is the first time that this new fighter has fought abroad, but according to the news that came back an hour and a half ago, this new fighter has achieved brilliant results in Saiyin Shanda, shooting down at least 80 fighters of the Chinese Air Force.

But is this really the case?

At 10 o'clock in the morning of June 8, 1940, following the air battle of Saiyin Shanda and the air battle of Ergen, the largest air battle over the Far East started in the sky over Zonmod, the capital of the Central Province of Outer Mongolia, 280 MiG-3 fighters and 340 J-series fighters and 340 B10 bombers met in the sky over Zonmod, and the two sides quickly launched a tragic air battle.

The intensity of the air battle far exceeded everyone's expectations, and because of the assistance of radar, Colonel Li Haitao, who was in charge of the bombing mission in the direction of Zonmod, received the news when the Soviet Air Force returned to Zonmod, and Major Li Haitao immediately ordered the escort fighter group to immediately break away from the bomber group and urgently go to intercept the Soviet fighter group, while the bomber group followed up.

Soon, the 9th Aviation Division, whose fuselage was painted with camouflage and whose wings were painted with the Soviet Red Star logo, appeared in the sight of Li Haitao and others. This is a fighter that Li Haitao has never seen before, with a streamlined design and a single wing.

Obviously, the Soviet pilots trusted the plane under them very much, and at the same time that Li Haitao and others discovered them, they also discovered Li Haitao and others, and the two sides quickly adjusted their formation, and then rushed towards each other. (To be continued......)
