"Attention, we are about to arrive over land. We will conduct the first course correction in Danzig." Yejinni shouted on the radio, notifying his formation.

Now they have 13 DB-3 bombers left, and their long voyage finally took a third.

Land is much more dangerous than sea, because the land will be contacted by the opponent's night fighters and ground air defense fire at any time, but they have no choice. They must fly this straight route to meet the need for round trips.

But now, it is about to enter the land, and as the flight continues to extend, the navigation error will become larger and larger, and they must rely on the ground coordinates to correct.

In the night flight, it is a normal thing to lose the course. Now, they have to check the course.

In front of the bomber’s nose, the pilot Slotov was sitting in his place, his eyes, looking down through the sighting device, he wanted to see the light of Danzig, so that he could aim at his own route. Up.

Now, the Germans are quite arrogant. They never thought that they would also be hit. Therefore, the Germans have no habit of controlling night lights. They can definitely find it. If they can’t find it, it must be a route. deviation.

Slotov was attentive. There was nothing in the black hole below. This made an ominous feeling in his heart. Isn't it lost?

So, where is your side? Could it be that your heading changed after being illuminated by the flares? After flying for more than an hour, even a one-degree error can cause a deviation of more than ten kilometers. Enough to miss a city.

Slotov was about to take out the route map to find out where he was. Just when his eyes were about to be removed from the optical device, suddenly, there was a bright light below.

In the dark, a person’s pupils will be enlarged, allowing more light to enter the person’s eyes, so that they can see clearly, but the sudden bright light makes the eyes too late to adjust, and the consequences are quite terrible.

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

The searchlight, this kind of strong light, the strong light coming from the ground, must be a searchlight, **** it, I was discovered by the German coastal defense forces! "Searchlight!" Slotov had only time to yell out such a sentence. Behind him, Yejinni had already discovered that the situation was not good.

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

He knew in his heart that it was not good. Now, his own bomber troops were afraid that it would be bad luck. As long as they can disperse, some of the bombers will run away.

And just as he gave the order, the antiaircraft artillery unit below had already begun to fire violently.

"Tom, Tom Tom." Just now, the radar has pointed them in the right direction. They have carried out various shooting calibrations in advance. Now, when the searchlight accurately captures the target, all that is left for them is One thing is to fire!

A self-propelled antiaircraft artillery fired violently. The 40mm Bofors antiaircraft artillery fired the most violently. In just ten seconds, more than 20 shells flew into the sky.

Gun smoke enveloped the battlefield, and under the light of searchlights, traces of cannonballs were so eye-catching that the entire sky was torn apart.

It is not easy for the anti-aircraft gun to hit the target because it attacks in a three-dimensional space. The previous artillery shells used direct collision as a method of killing. Only when they can hit the target can they be powerful, even if it is rubbed. Passing by, it will not bring any threat.

At the same time, in order to avoid the threat of projectiles falling, the warheads are designed to explode. For example, ordinary small-caliber projectiles will explode almost at a height of 3,000 meters without touching 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 in the tens of thousands of flowers, not touching the mud, and only when bombing cities with a lot of air defense firepower, the danger will increase.

But this shell is different now.

The bullet’s warhead is made of copper. Now, the shell also plays another role. It is 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 a radio of 180 to 220 MHz.

Yes, this is the radio proximity fuze. 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 fuze was first invented by the Americans, and was regarded as an absolutely confidential weapon, which could only be used in complete safety to avoid being acquired by the other party.

But Germany does not matter.

Germany's radio technology is one generation ahead of other countries. Now the main force in Germany is transistors, and other countries have no idea about the principle of transistors, let alone mass production.

Therefore, it is impossible for other countries to imitate.

It is precisely because the transistor has effectively reduced the volume that it is possible to equip small-caliber antiaircraft artillery with such shells~www.novelhall.com~ In history, only 127mm shells can be inserted into this stuff by Americans. child.

Tracers can still be emitted from the outside, allowing the antiaircraft artillery troops to see clearly, this graceful arc is flying towards the target.

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

The warhead is rapidly approaching the target, so that the radio signals emitted by the warhead begin to be reflected by the target.

As the distance between the shell and the target decreases, the Doppler effect causes the reflected radio waves to create a low frequency signal of 200-800 Hz in the current of the transmitter. After filtering and amplifying this signal, it finally reached the initiation requirement!

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

"Boom!" The 40mm shell exploded violently. During the explosion, countless shrapnel expanded toward the surrounding airspace. The 40mm 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. The fragments collided with the fuselage, making a terrible noise.

A shrapnel flew over the rotating propeller, hit the engine, and slashed a small oil pipe.

The dark red aviation gasoline splashed out, and when it splashed on the cylinder fins, it instantly caused a terrible fire.

"The left is on fire." The pilot beside Yejinni shouted.

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

The two were hurriedly operating, and the bomber had already begun to roll and fall down. ()
