World War II was a catalyst for advanced technology, especially radar.

Before World War II, radar was only a concept, but after the end of World War II, various radars have been able to have a perfect actual combat state.

For radar, the most critical component is the magnetron. This is a special vacuum tube that can release electromagnetic waves from it. Yes, it is the element that emits electromagnetic waves. Without it, there would be no radar.

Historically, the magnetron existed in 1921, but the multi-cavity high-energy magnetron was not invented by Lander and Bout of the University of Birmingham in the United Kingdom until 1939.

Radar waves have different wavelengths and frequencies. For example, in later generations, in order to counter stealth aircraft, meter-wave radars are used. The longer the wavelength, the easier it is to radiate energy and have a longer detection range.

However, its accuracy is not enough. If you want to improve the resolution better, you must reduce the wavelength of the radar. This is the purpose of the multi-cavity high-energy magnetron, which enables the radar to work in the microwave band with greater pulse intensity. . It makes the target's comprehensive resolution accuracy, azimuth accuracy and distance accuracy improved by orders of magnitude, makes the antenna smaller and higher performance, makes the sea surface and terrain interference clutter better detected, and makes the pulse width reach the microsecond level. The minimum detection range is shortened from half a mile to a few hundred yards, so that the guns of the interceptor can be completely controlled by radar, and the bulky antenna can be reduced to fit into a wing or a bomb-sized pod.

After talking for a long time, now ordinary shipborne radars can only know that the enemy aircraft is in a certain airspace, but the specific location is not clear and cannot guide naval guns to intercept. However, this new fire control radar, due to the improved accuracy, Perfectly achieve the purpose of fire control radar, it can guide the antiaircraft artillery, perfectly turn to the target location, and then fire!

Germany’s previous radars were mainly based on magnetrons imported from island countries and then developed. After the conquest of the United Kingdom, this multi-cavity high-energy magnetron technology was also acquired by Germany. Later, based on this magnetron , Germany developed the first gun sight radar.

Now, this radar is installed on the Lützov and used to control the twin-mounted 88mm anti-aircraft gun. After receiving the order, the preheated radar was turned on immediately. The radar wave of 2900 MHz, instantly Scan past the cloud.

The cloud formed by the condensation of water vapor cannot block the electromagnetic waves. Only the aluminum skin of the fighter plane can clearly reflect these echoes. Now, with the echoes, they accurately flash on the screen of the fire control radar.

Then, the radar soldier began to report quickly: "The altitude is two thousand five, the azimuth is 0-3-6, the elevation angle is 75 degrees, 3 minutes and 2 seconds, and the distance is three thousand one. Please calibrate and shoot the yuan immediately."

If you want the radar to automatically control the anti-aircraft artillery, it is still impossible. The current gun aiming and fire control radar can automatically calculate the target's azimuth, elevation, distance, and height based on the detected target data. And important information about firing, this is already quite efficient.

While the radar continued to automatically track the target, the gunners were rapidly turning the steering wheel at the gun position of the antiaircraft artillery, and the antiaircraft artillery made fine adjustments. Then, **** of fire came out from the muzzle.

"Boom, boom, boom!"

At this moment, suddenly, a huge wave hit the hull of the Lützov. As the hull swayed, the muzzle shook and missed.

On warships, the base of the naval gun will sway with the hull, so that the naval gun will deviate when firing. In order to prevent shooting errors, on the Bismarck, the 105mm naval gun is equipped with a three-axis self-stabilizing The platform, no matter how the hull shakes, the naval gun stands tall, showing the strength of this naval gun.

However, there was no such equipment on the Lutzov.

The slight shaking of the gun body will cause a major deviation of the shell. At this time, in the control room of the fire control radar, the radar soldier shouted: "Quickly, lower the elevation angle immediately, it rushed down!"

Even without fire control radar, other high artillery soldiers caught the American-made pirate fighter with their naked eyes. At this moment, it suddenly emerged from the clouds, with a swift and terrible momentum, and began to dive downward, its target , Is the Munich aircraft carrier in the formation!

Fire, fire!

The dozen or so warships escorting around all turned their antiaircraft artillery over. 40mm, 88mm, and 105mm antiaircraft artillery shells were constantly swayed into the sky, and the smoke enveloped the entire target airspace.

If you want to dive down, you have to pass through this terrible barrage, which is simply seeking a dead end.

At this time, Roy did not flinch. He felt his plane trembling in the explosion of the antiaircraft artillery shells, and felt the roar of countless shells. Roy continued to dive and dive.

"Boom!" An 88mm artillery shell exploded almost only a few meters away from his plane~www.novelhall.com~ Numerous fragments hit his plane, and the front engine suddenly burst out. The black smoke burst out following the flames.

There were also several shots on the fuselage. In the cockpit, Roy felt like he had been bitten on his thigh.

Roy was injured.

The smoke from the nose of the aircraft in front was getting bigger and bigger, Roy's eyes were full of determination, and the aircraft carrier below was getting clearer and clearer.

"Justice will win!" Roy yelled on the radio. There was still a noisy voice. It was his companions who were still fighting. For him, this was a just war, and Germany tried to rule the whole country. The world will inevitably end in failure.

The pirate fighter with heavy smoke continued to dive down. Below, the Munich aircraft carrier was also anxious, and the captain issued a left full rudder instruction, trying to avoid the fire fighter.

With admiration in the captain's eyes, the pilot of that fighter plane had already dived with a decisive belief. In order to attack, the opponent would rather sacrifice his life.

Well, it's absolutely worth it to exchange his life for an aircraft carrier!

"Tom tom tom, boom!" At this moment, the roaring 40mm Bofors artillery shell landed on its body. The shell tore the rear of the fuselage and hit the fuel tank. The whole plane suddenly exploded in the air.

The high artillery soldiers cheered in an instant.

Great, hit it!

The exploded pirate fighter jet blazed in the air. It was still diving down its original trajectory. There was already an open sea area. Then, it plunged into the sea.

In the sky, Alcatel witnessed all this, and suddenly, he felt that his heart was empty, as if he had lost something. His gaze stayed on the fighter plane that crashed into the sea, unable to calm down for a long time.
