Transistors have begun to be mass-produced in Germany, and the emergence of this semiconductor component has greatly reduced the size and weight of electronic equipment, and rapidly changed the level of electronic equipment in Germany.

However, not all equipment can be replaced by transistors, and even in later generations, some of the components in the radar still exist with tubes.

First of all, warm up!

In the dark night sky, a large net has been gradually spread, and at this time, the British bomber force still knows nothing.

"Attention, four thousand in height, prepare to wear a breathing mask." As he climbed, Captain Hodder said to his crew.

With the increase of altitude, the air begins to thin out, and the oxygen also decreases, so the high-altitude flying engine needs a supercharger to be able to work, and some advanced engines have begun to use the two-stage supercharger, in order to achieve higher supercharger efficiency.

At the same time, people can't stand it.

In World War I, planes flew almost at an altitude of one or two thousand meters, and there was no cockpit cover, and now, the flight altitude of bombers is getting higher and higher, after all, the higher it is, the less threatening the opponent's anti-aircraft guns.

In this way, it is necessary to consider the issue of oxygen intake by personnel.

Hodder said as he put the oxygen mask in front of him to his lips.

If you don't get enough oxygen at a higher altitude, you'll faint at any time. It's just that after putting on the oxygen mask, the whole person looks even more clumsy.

Although in general, it takes more than 6,000 meters to risk oxygen deficiency, almost all of them start wearing it around 4,000 meters.

"The route is correct, it has entered the skies over France, and it is expected to reach Paris in twenty minutes." Again, the navigator checked the coordinates, especially when he saw a lighthouse on the shoreline, and he was completely confirmed.

Keep flying!

"Attention, First Brigade, about to stagger with the target, please turn in the airspace ahead." At this time, at an altitude of five thousand meters, Werner's headset was also receiving messages from the target.

The ground has successfully guided them to the course of the opposing bombers, at this time, by visual sight, nothing can be seen in the dark sky, but it is certain that the other side is there!

In interception, it is necessary to fly head-on, however, they do not make a head-on interception, and such a hit rate is the lowest.

As the route passed by the opposing side, Werner pushed the lever and the fighter began to turn down to the right.

At the same time, Fisher, the radar operator next to him, was engrossed.

At the beginning, the radar was only in a warm-up state, and when the steering was completed, the radar had already entered a state of full power.

Electromagnetic waves pass through the four antler antennas in front of them, filling the area within the 70-degree cone angle ahead.

This kind of radar not only has a limited range, but also has a very small azimuth, so it is impossible to accurately find the target only by relying on the carrier aircraft.

"Attention, 1st Brigade, the target is in the area of fifty degrees in front of the right." The sound of ground guidance continued to be heard in the headphones.

Radar guidance on the ground, radar search in the air, and visual discrimination by pilots are all very important. Like now.

After the sound of the ground guide came, Werner adjusted his course and searched the dark sky with his own eyes, and at the same time, next to him, Fisher was pleasantly surprised to see shining points of light on his radar screen.

"Target found!" He shouted happily: "Right in front of us, three kilometers away!" ”

If it was daytime, it would have been clearly visible at this distance, but now it is night, in the dark night sky, the visual distance is no more than a kilometer, and nothing can be seen at all ahead!

"Attention, Night Fighter Group, the target is directly in front of us, ready to attack, take care to prevent collisions." Werner shouted to his men.

Yes, under such conditions, it is necessary to prevent accidental collisions, and the dark night sky is a great challenge for the flight of large aircraft groups.

And now, Werner's subordinates are all veterans of many night flights, and they are extremely excited when they hear the news that their radar operators have intercepted the target, and the first battle of the night fighter unit is about to begin!

Onward, keep going!

As a professional night fighter, this aircraft has its own special indicators when it is manufactured.

For example, the cannon must be at the back of the cockpit to prevent the pilot from being blinded by the light of the cannon's fire, and the aircraft must have enough payload to carry radar equipment.

Another example is the speed of the airplane, which needs to be high enough!

You must know that the two magic weapons of the bomber are altitude and speed, and the higher these two indicators, the greater the chance of survival.

Therefore, a night fighter modified with a Junkers-88 bomber is not fully competent, only such a professional night fighter will do! When it was designed, an important metric was speed!

The current fighter jet, in the test, once ran a speed of 700 kilometers per hour, dwarfing many Air Force fighters.

In night combat, it must be a tail chase attack, if the speed is not high enough, it will not be able to catch up at all!

For example, the current Blenheim bomber has accelerated to 400 kilometers per hour, which is not low, but in front of the German night fighters, it is just a slow fly!

Chase, chase! Soon, in front of Werner's eyes, a vague outline appeared, and the target was spotted visually!

"Be careful, each fighter finds its target, turns to tracking mode, and does not fire immediately!" Werner continued to give orders.

Now the other side is flying in large formations, with more than a dozen bombers, enough for their own night fighter units, and they have all found their targets.

If you fire now, you will only kill one at most, because the remaining bombers will definitely flee in panic, so it will be difficult to find them again, especially if the other side rushes into a low altitude, the radar will be useless.

Although it was a large formation, the other side flew relatively scattered, after all, it was night, and dense formations could easily collide.

Werner shouted as he pushed his lever and leaned in cautiously.

The huge bubble cockpit gave the pilot a 360-degree omnidirectional field of vision, and as he got closer, he could see more clearly, and Werner quickly recognized the other party's model: "It's a Blenheim bomber, there is no belly turret, it's time to try our oblique music!" Let the British bomber units tremble! ”
