"Note that we will make our first course proofreading in Danze," Ye Jinni shouted in the radio, notifying his formation.

Now, they have 13 db-3 bombers left, and their long sailing finally left one third.

Land is much more dangerous than sea because land can be contacted by the opponent's night fighter jets and ground air defense fire at any time. However, they have no choice. They must fly this straight route to meet the needs of round trips.

Now, we are about to enter land. As the flight continues to extend, the navigation error will become larger and larger. They have to rely on the coordinates of the ground to correct it.

It is normal to lose your course during night voyages. Now, they have to proofread the route.

At the nose in front of the bomber, the navigator Slotov sat in his position. His eyes looked down through the sighting device. He wanted to see the light of Danze City so that he could aim at his own route.

Nowadays, the Germans are quite arrogant. They never thought that they would suffer a blow, so the Germans did not have the habit of night light control at all. They would definitely find it. If they could not find it, it would definitely be that the route was deviated.

Slotov was concentrating on his mind, and there was nothing underneath, which made an ominous feeling surge in his heart. Could it be that it was a Trek?

So, where is our side? Could it be that after being illuminated by a flare, our side's course changed? After flying for more than an hour, even a degree of error will cause a deviation of more than ten kilometers. It is enough to miss a city.

Slotov was about to take out the road map and find out where he was. Just as his eyes were about to move away from the optical device, suddenly, a ray of light shone below.

In the darkness, the person's pupils will be dilated, allowing more light to enter the person's eyes, so that you can see clearly. However, the sudden strong light makes the eyes unable to adjust, and the consequences are quite terrible.

For example, now, Slotov suddenly felt a strong light sting his eyes. He was covered with white light in front of him, and he couldn't see anything clearly, but his heart was extremely clear.

Searchlight, this kind of strong light, the strong light coming from the ground must be a searchlight. Damn, he was actually discovered by the German coastal defense forces! "Searchlight!" Slotov had only time to shout such a sentence. Ye Jinni had already discovered that the situation was not good behind him.

"Please disperse immediately and get rid of the searchlight!" At this time, light columns shone from the ground to the sky, and their planes were actually shrouded by these light columns!

He knew something was wrong. Now, his bomber troops were afraid that they would be in danger. As long as they could disperse, some bombers would still run away.

And just as he issued the order, the anti-aircraft artillery troops below had already begun to fire violently.

"Bang, bang." Just now, the radar had pointed them in the right direction. They calibrated various shooting elements in advance. Now, when the searchlight accurately captured the target, there was only one thing left for them, which was to fire!

One by one, the self-propelled anti-aircraft guns were firing violently. The 40-mm Bofos anti-aircraft guns fired the most violently. In just a dozen seconds, more than twenty shells flew into the sky.

The smoke of gunpowder enveloped the position, and under the light of the searchlight, traced shells were so eye-catching that the entire sky was torn to pieces.

It is not easy for anti-aircraft guns to hit the target because they attack in three-dimensional space. In the past, shells were killed by direct collision. Only when they could hit the target can they have power. Even if they pass by, they will not bring any threat.

At the same time, in order to avoid the threat of falling shells, the warheads are designed to self-destruct. For example, ordinary small-caliber shells will almost explode at an altitude of 3,000 meters after they do not touch the target.

The blooming of small black flowers made the bomber troops look thrilling. They passed through these small black flowers, but there was actually no particularly threat. For example, in most air defense operations in World War II, on average, almost thousands of shells were fired to successfully intercept an aircraft.

Passing through the flowers, without any mud, the danger will only increase when bombing a city with a large amount of air defense firepower.

But now this kind of shell is different.

The shell's warhead is made of copper, and now, this shell has another function, it is an antenna.

Inside the warhead, there is a small transistor radio wave transmitter. When it flies out of the muzzle, the circuit is turned on under the action of inertia. Using the warhead antenna, it begins to emit radios of 180 to 220 megahertz outward.

Yes, this is the radio near-fighting fuse. Germany has overcome all technical difficulties and successfully carried out mass production. Compared with ordinary warheads, its manufacturing cost is at least ten times higher, but its hit rate can be increased by two orders of magnitude!

In later generations, this kind of fuse was first invented by Americans and was regarded as an absolutely confidential weapon. It can only be used when completely safe and avoid being obtained by the other party.

But Germany doesn't matter.

Germany's radio technology is one generation difference ahead of other countries. Now Germany's main force is transistors, while other countries still cannot understand the principles of transistors, and there is no mass production.

Therefore, it is impossible for other countries to imitate it.

It is precisely because the transistors effectively reduce the volume that small-caliber anti-aircraft guns have been equipped with such shells. In history, Americans could only have 127 mm shells stuffed into this kind of thing.

Tracer can still be emitted outside, allowing the anti-aircraft artillery troops to see clearly, and this beautiful arc flew towards the target.

At this time, the target aircraft is maneuvering and dodging. If it follows the route, it will pass by the target, but now, its mode of action has changed.

The warhead is quickly approaching the target, so the radio signal emitted by the warhead begins to be reflected back by the target.

As the distance between the shell and the target decreases, the Doppler effect causes the reflected radio waves to cause a low-frequency signal of 200-800 Hz in the current of the transmitter. This signal is filtered and amplified, and finally meets the detonation requirement!

At this time, the warhead is still ten meters away from the target, and the low-frequency signal reflected back has already triggered its electric detonator.

"Boom!" A 40mm shell exploded violently. During the explosion, countless shrapnel expanded towards the surrounding airspace. The 40mm shell exploded enough to cover a space with a radius of fifteen meters.

The db-3 bomber inevitably entered this space filled with shell debris. The debris collided with the fuselage and made a terrible sound.

A shrapnel flew over the rotating propeller and smashed into the engine, cutting a tiny oil pipe.

The dark red aviation gasoline splashed out, and when it splashed on the cylinder heat sink, it instantly brought a terrible fire.

"The left is on fire." The pilot next to Ye Jinni shouted.

Their plane was hit! Ye Jinni shouted loudly: "Come on, turn off the engine!"

The two were operating in a hurry, and the bomber had already started to roll and fell downward.
Chapter completed!
