Tu-4 bombers, that is, B-29 bombers, which the Soviets imported from the United States at great cost, these valuable aircraft, a total of fifty, the Americans promised the supply of spare parts, but absolutely not to give more quantities.

Therefore, the Soviet bomber units must cherish these planes and not let them suffer great losses in the war.

At the same time, it is necessary to carry out combat missions, which is simply a huge contradiction, and there is only one way to solve this contradiction.

Fly at ultra-low altitude at night.

Flying at night, visibility is very low, and in this case, an ordinary daytime fighter will not be able to see such a target as a bomber at all, so it is quite safe.

The only thing that can threaten them is the night fighter, which is specially modified to carry out night combat missions, has a good field of vision, a long stay in the air, fierce firepower, and more importantly, it is equipped with radar equipment.

Although it is impossible to visually find the target in the dark, the radar will open the eyes of the night fighter pilot, so that they can see the target clearly, and then cooperate with the radar station on the ground to carry out the mission, absolutely with ease.

In this case, high-altitude bombing at night is also quite dangerous, and at the same time, they are at high altitude, the route is straight, and it is easy to expose the target.

In this way, low-altitude bombing is inevitable.

Of course, there is another reason.

At this time, they did not know that the Americans had successfully developed an advanced Norton high-altitude bombing sight, and the Americans had replaced their planes with backward original bombing devices, so that the accuracy of high-altitude bombing was quite poor, and if they wanted to improve accuracy, it was inevitable to reduce the flight altitude.

As for why it has only been transferred to a low altitude until now, if it has been flying at a low altitude all the time, whether the fuel is enough or not is another matter, just the confirmation of the route is enough to make the navigator collapse.

Now, they can find their target accurately by aiming at the course, and at the same time they have to enter the German mainland, and the dense network of ground-based radars will make them have nothing to hide, and they have to go to low altitudes.

With the order of Wasltzjego, one bomber after another, lowered from the high altitude, dived into the vast land, flying in the dark, prone to hallucinations, believing that the instrument was the only way.

The target is Munich, located in the Upper Bavarian High Plains of the Free State of Bavaria, about 45 km from the northern foothills of the Alps, at an altitude of about 520 m above sea level.

This is also one of the reasons why they can carry out ultra-low-altitude bombing, the other side is on the plains, the Alps are just south of Munich, if they bomb to the south, ultra-low-altitude flight is to find death.

Their flight altitude is one thousand meters, which is about five hundred meters above the ground, and the huge Tu-4 bombers are almost flying close to the ground at this altitude, and those nasty night fighters can't find them at all.

"The radar echo disappears." In Berlin, Richthofen was also constantly receiving messages and disappeared from the radar screen just after the target group flew over Prague.

Of course, the other side will not be wrecked and crashed, let alone fly away, the other side must have turned to an ultra-low altitude, evaded its own radar and night fighters, and rushed towards its own Munich.

"It seems that the Soviets are really smart enough to take advantage of our loopholes so obviously, I guess the deployment of our territorial air defense forces must have been leaked." Richthofen said through gritted teeth.

This time, his side was disgraced, and if there was no leakage of information, Hitthofen absolutely did not believe that in a war, spies on both sides would never be caught.

After this incident has passed, a major transfer must be carried out, and at the same time, an investigation must be carried out to find out the spies!

"They're flying at super low altitudes now, so it's a good opportunity for us." At that moment, one of the assistants said: "If they can't find our city and keep flying, then fly to the Alps." ”

The words of the assistant made Richthofen's eyes light up immediately, yes, this is a good idea!

As a person who climbed up step by step from the bottom of the Air Force, Richthofen certainly knew the difficulties of flying at night, especially navigation, although Munich to the Alps was almost fifty kilometers, but in the air, it was only a short ten minutes, and for a crew that had flown long distances for several hours, these ten minutes, almost negligible.

Because of this long flight, they have accumulated a lot of route error.

"Don't open fire from the first ambush position, in the second ambush position in Inbrusko, prepare for an ambush, evacuate all the citizens of Inbrusko, turn on their lights, impersonate Munich."

Inbrusco, a small town at the foot of the Alps on the extension line south of Munich, will make the enemy planes in the sky believe that it is true, and then, when they fly over, they will suddenly find a huge mountain range in the darkness, and when the time comes, it will definitely be too late to dodge!

Nearby is the Harvard Leica Peak, which is thousands of meters above sea level, enough to reimburse their bombers.

This small town at the foot of the mountain is mainly engaged in tourism, and many people will start to climb the mountain from here, and it is summer, so there are not many people who climb the mountain, and the snow-capped mountain is the beauty here.

Even so, in order to reduce the number of innocent casualties, it is necessary to evacuate those citizens.

Richthofen did not know at this time that his order had saved the lives of hundreds of citizens in the town, and the anti-aircraft artillery of the second ambush position here had died heroically.

With the speed of the opponent, it will take about forty minutes to reach Munich, which is enough to efficiently complete the arrangement of the second position.

Now, the empire is developing radar to be installed on airplanes, but the technical problems it faces are even greater, and if you want to see the ground from the sky, radar clutter is simply a huge problem.

Now, the other party has disappeared from the radar screen, and the trajectory of the other party can only be judged in advance, and if the judgment is wrong, other cities will suffer huge losses tonight.

Richthofen completely trusts his own judgment, as for the reason, it is also very simple, if you fly at ultra-low altitude, the range of sight will become smaller, and it is quite difficult to navigate the navigator, and you will not be able to find the predetermined positioning point at all, and even if you find it, you will fly by, there is no reaction time at all, you can't correct the route, and a direct flight is the most likely.
