Chapter 1771： Electromagnetic interference (1/2)
Hindenburg.
At this time, the ship’s radar can also clearly capture the target, and all anti-aircraft guns are preparing nervously, especially the 128mm antiaircraft gun, which has the longest range. As long as the opponent is close, it will fire without hesitation. .
However, the Americans are very cunning. Before they were within the shooting range of the surface ship's anti-aircraft artillery, they had already dropped bombs in advance.
This is the advantage of dropping bombs at high altitudes. The higher the altitude, the farther they can be thrown. At this time, the B-29 bombers are still ten kilometers in front of them, beyond the maximum slant range of the 128mm anti-aircraft gun.
Therefore, in the face of the American bombardment, Riddle on the Hindenburg could only give one order: ”The entire fleet, with the rudder left full, turn on the jamming device.”
The accuracy of dropping bombs at a height of 10,000 meters is quite poor. Now, the entire fleet has a full rudder on the left to make those bombs miss.
However, the Americans must have come prepared. When bombing at an altitude of 10,000 meters, most of the free-fall bombs will definitely miss the target. Their bombs are just to cover up the real killer.
The kind of bombs that can be precisely guided, like similar bombs in Germany, the Americans already have.
If it is the first time encounter, maybe the German fleet will suffer, but it is not the first time. The island fleet has suffered heavy losses under the bombing of this special bomb, and how can Germany make the same mistake again!
The head of Cyrenk has always attached great importance to electronic warfare. Transistors were made ahead of time, and the pre-research of various electronic technologies, including the appearance of electronic computers, was the result of the single-handed promotion of the head of Cyric.
And just after this kind of precision-guided bomb appeared in the US arsenal, Germany was tit-for-tat and developed an electromagnetic interference device.
Every large warship is equipped with this special electronic equipment. For example, on the Hindenburg, a Yagi antenna stands above the rear turret. At this time, this antenna is continuously moving outwards. It releases electromagnetic waves, and its power is so great that when it starts, the bulbs inside the entire naval vessel's cabin are dimmed.
Electromagnetic interference is a science, what is the frequency of the other party? What band is used to interfere? Should the interference be a normal signal or an analog signal of the other party? These are the specific problems of electromagnetic countermeasures.
But for now, there is no need to think about so much for the time being. It is enough to launch chaotic electromagnetic waves against the sky. The huge electromagnetic waves fill the sky and immediately submerge the opponent's guidance signal.
In the words of later generations, this is called full-band, large-blocking interference. This is the most irritating interference method. No radio communication equipment can work under this interference, even if the frequency band is reserved in advance. German frequency hopping The radio was also subject to some interference at this time, not to mention the American guided bombs.
At this time, the American bombardier in the sky didn't know. He just thought that the bomb he threw had malfunctioned, and could not help shouting: ”Damn it, mechanical failure, I can't control it!”
The bomber was very upset, and watched the opponent's fleet turn around on the sea, avoiding the area where his bomb fell, but he was helpless.
At this time, the pilot above his head didn't care about so much. The noisy signal in the headset made him a little tinnitus. He stared at the sky nervously. A German jet was swooping toward his plane.
”Tom Tom Tom!” On both sides of the opponent's nose and wings, three 20mm cannons fired together. The dense shells flew towards them, so the pilot immediately manipulated the bomber to turn left, trying to avoid the opponent. Shells.
”Boom, boom, boom!” The nose avoided, but the position of the bombardier on the nose did not avoid it. The 20mm shell knocked on the front glass, blasting the bomber to blood.
