Chapter 1188 Proximity Fuze (Plus 1)

"Attention, we are about to reach over land, and we will conduct the first course correction in Danzig." Yejinni shouted in the radio, informing his formation.

Now, they still have 13 DB-3 bombers left, and their long voyage has finally gone a third of the way.

The land is much more dangerous than the sea, because the land will be contacted by the opponent's night fighters and ground anti-aircraft fire at any time, but they have no choice. They have to fly this straight route to meet the needs of the round trip.

And now, it is about to enter the land. As the flight continues to extend, the error of the navigation will become larger and larger, and they have to rely on the coordinates of the ground to make corrections.

Losing course is a normal thing in a night flight, and now, they have to calibrate the course.

In the nose in front of the bomber, the navigator Slotov is sitting in his place, his eyes, looking down through the sighting device, he wants to see the light of the city of Danzig, so that he can focus on his own route .

Now, the Germans are quite arrogant. They never thought that their own side would also be hit, so the Germans have no habit of controlling lights at night. They can definitely find it. If they can't find it, it must be an air route. deviation.

Slotov was concentrating, and there was nothing in the darkness below, which made an ominous feeling in his heart, could it be lost?

So, where are you? Could it be that after being hit by the flare, the course of the side changed? After flying for more than an hour, even a one-degree error will cause a deviation of more than ten kilometers. Enough to miss a city.

Slotov was about to take out the route map and find out where he was, when he was about to take his eyes off the optics when suddenly there was a light below.

In the dark, people's pupils will be enlarged, allowing more light to enter the people's eyes, so that they can see clearly, and the sudden strong light, the eyes have no time to adjust, the consequences are quite terrible.

For example, now, Slotov suddenly felt a strong light stinging his eyes. All the light in front of him was white, and he couldn't see anything clearly, but his heart was very clear.

Searchlights, this kind of strong light, the strong light from the ground, must be searchlights, damn, they were discovered by the German coastal defense forces! "Searchlight!" Slotov only had time to call out such a sentence, behind him, Yejinni also found that the situation was not good.

"Attention, spread out immediately and get rid of the searchlights!" At this time, beams of light beamed from the ground to the sky, and these planes were actually shrouded in the beams of light!

He knew in his heart that it was not good. Now, his own bomber troops are afraid that there are more bad luck than good luck. As long as they can disperse, some bombers will still run away.

And just as he gave the order, the anti-aircraft artillery units below had begun to fire violently.

"Tom, tom." Just now, the radar had pointed them in the right direction, and they had calibrated various shooting elements in advance. Now, after the searchlight accurately captured the target, all that was left for them was One thing, fire!

A self-propelled anti-aircraft gun fired violently. The 40mm Bofors anti-aircraft gun fired the most violently. In just a dozen seconds, more than 20 shells flew into the sky.

Gunpowder smoke shrouded the position, and under the light of the searchlight, the trailing shells were so striking that the entire sky was torn to pieces.

It is not easy for the anti-aircraft gun to hit the target, because it is attacked in three-dimensional space. The previous artillery shells used direct collision as the killing method. Passing by, it will not bring any threat.

At the same time, in order to prevent the shell from falling and causing a threat, the warheads are designed to self-detonate. For example, ordinary small-caliber artillery shells almost all self-detonate at an altitude of 3,000 meters after not hitting the target.

The small black flowers bloomed, making the bomber troops look thrilling. They passed through these small black flowers, but there was no particular threat. For example, in most air defense operations in World War II, on average, almost It takes thousands of shells to successfully intercept an aircraft.

Passing through thousands of flowers without sticking to the mud, and only when bombing cities with a lot of anti-aircraft firepower, the danger will increase.

But now this shell is different.

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

Inside the warhead, there is a small transistor radio wave transmitter. After flying out of the muzzle, under the action of inertia, the circuit is turned on. Using the warhead antenna, it starts to emit 180 to 220 MHz of radio.

Yes, this is the radio proximity fuze. Germany has overcome all technical difficulties and successfully mass-produced it. Compared with ordinary warheads, its manufacturing cost is at least ten times higher, but its hit rate can be improved by two orders of magnitude!

In later generations, this fuze was first invented by the Americans, and was regarded as an absolutely secret weapon, which could only be used in complete safety to avoid being obtained by the other party.

But Germany doesn't matter.

Germany's radio technology is a generation ahead of other countries. Now Germany's main force is transistors, while other countries still don't understand the principle of transistors, let alone mass production.

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

It is precisely because the transistor effectively reduces the size that it is possible for small-caliber anti-aircraft guns to be equipped with this kind of shells. Historically, only 127mm shells can be stuffed into this kind of thing in the United States.

Tracers can still be fired outside, allowing the anti-aircraft artillery units to see clearly, this graceful arc flies towards the target.

At this point, the target aircraft is maneuvering to evade, and if it follows the course, it will miss the target, but now, the way it works has changed.

The warhead is rapidly approaching the target, so that the radio signal emitted by the warhead starts to be reflected back by the target.

As the distance between the projectile and the target decreases, the Doppler effect causes the reflected radio waves to cause a low frequency signal of 200-800 Hz in the transmitter's current. This signal has been filtered and amplified, and finally, it has reached the detonation requirements!

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

"Boom!" The 40mm artillery shell exploded violently. During the explosion, countless shrapnel expanded towards the surrounding airspace, and the 40mm artillery shell exploded, enough to cover a space with a radius of 15 meters.

The DB-3 bomber inevitably entered this space full of shell fragments, and the fragments collided with the fuselage, making a terrible noise.

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

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

"The left engine is on fire." Yejinni's side of the pilot shouted.

Their plane was hit! Yekini shouted loudly: "Quick, shut down the engine!"

The two were operating in a hurry, and the bomber had already begun to roll and fall.
