"The D-radar is on! Three, two, one! The test begins! At the same time that the Air Force was installing two new fighters, a German technical engineer in a white lab coat commanded with his head bowed and looking at his notebook.

"Power on!" Sitting in front of him was a radar technician who flipped the switch in front of him and energized the entire radar.

A special, faintly glowing radar screen shows an analog signal of the radar beam, which looks very intuitive.

Early models of radar transmitted fluctuating signals similar to electrocardiograms, which required analysis by radar operators to obtain a blurred data.

Germany has integrated radar signals, and radar screens similar to those of later generations have begun to appear, and can intuitively reflect the distance of the target.

There are concentric circles depicted on the radar screen, which indicate the distance of outward diffusion, and a concentric circle represents ten kilometers, which is very intuitive and convenient.

With such a screen, the workload of the radar operator plummets, and the contribution of the radar to fire control is also reflected.

As long as the radar is accurate enough, it can guide the battleship's main guns to fire and attack targets outside the line of sight. Coupled with the artillery correction aircraft, it is possible to hit distant targets very quickly and accurately.

The D-type radar is the latest long-range fire control radar developed by Germany, with a detection range of more than 70 kilometers and an effective guidance range of more than 25 kilometers.

It can command the guns on battleships with great precision, and its size can only be installed on battleships.

In order to achieve good accuracy and perfect reliability, this radar sacrifices volume, and the D-type radar at this stage can only be installed on battleships and heavy cruisers.

The complex CRT technology of televisions is used in advanced radar. From now on, radar soldiers don't need to be trained in beam analysis, they just need to be able to understand the bright spots on the screen.

This gives the latest German radar a very intuitive expression of the distance and the number of enemies, and also improves the performance indicators of the German radar.

"The target is 23 kilometers from the ship! coordinates 71-23, you can fire immediately! Seeing the scale on the radar, the radarman reported into the microphone.

"What's going on with the rangefinder? Can you give an accurate distance prediction? A colonel officer stood on the bridge and turned his face sideways to ask the adjutant beside him.

"Sir, the rangefinder gives a result between 22 and 26 kilometers. The false target is too small for the observation instrument to be too accurate. The adjutant replied.

"You can fire!" Putting down the binoculars, the general, who had not spoken all this time, raised his chin and opened his mouth to order: "Fire according to the data given by the radar, and let the carrier-based aircraft report the strike!" ”

There were also carrier-based aircraft on the battleships, which were responsible for providing fire-corrected guidance for over-the-horizon strikes on battleships.

However, this situation can only happen after both sides only have battleships, or they have already gained air supremacy.

Otherwise, risk taking off the seaplanes on the battleship to direct the artillery strike, which can easily be shot down by the opposing fighters.

Now it is the radar test stage, and it is natural that there will be no danger for the take-off aircraft to observe the results of the shelling, so there is no need to worry about being shot down.

"Boom!" The front main gun of the battleship Bismarck suddenly opened fire, and a 381 mm heavy gun on turret No. 1 spewed a cloud of flames.

"Boom!" Turret 2 also erupted in dazzling flames less than half a second later, and another shell was fired at the same angle.

Everyone waited quietly, after all, it would take a lot of time for the shells to fly more than 20 kilometers away.

Some of them could not wait, and the commander-in-chief of the Atlantic Fleet, General Rutteyans, who was standing on the bridge to watch the radar fire control test, picked up the binoculars again and looked in the direction of the shelling.

He commanded the naval battle, and the artillery battle between the battleship Bismarck and the battlecruiser Hood of the British Navy was as if it had happened yesterday.

He always remembered the picture of the battleship Bismarck being shot in the middle of the hull and retreating to the Brest military port for repairs in black smoke.

At that time, there was no fire control radar on the battleship Bismarck, only a reconnaissance radar. And that reconnaissance radar has become a treasure that turns the tide of the war.

At the same time, the German Navy was still a maritime guerrilla force with only a few warships, and every time it went to sea, it had to dispatch all the warships that could be dispatched, barely making up the size of a few warships.

The Zeppelin aircraft carrier was the core of the fleet, and there were very few battleships left that simply could not be compared with the powerful British Royal Navy.

Today, however, the once mighty Royal Navy has been emasculated and disbanded, and the German Navy has too many warships to be manned......

Even Rutteyans, who witnessed the entire process of the Atlantic naval battle, had to sigh that the world was changeable.

"The first shell landed close! The second shell landed in a remote location! It's all close to missing! My God! It's all close to missing! Soon, the reconnaissance plane that retested and observed the results of the shooting returned, and the pilot's voice was trembling.

In naval warfare, if you can achieve a straddle fire effect with the first shot, it can really be said that you can really say that you have an aiming accuracy against the sky.

Although only two shells were fired, as long as you keep this straddle fire, you have a better chance of hitting the target!

And for the D-type fire control radar being tested, two or three salvos can hit the target, which is already very, very anti-sky performance.

"Let the artillery fire a salvo! Don't wait, just shoot a salvo and see if you can hit the target! Lytjans gave the order to open fire with great interest.

This is not just an over-the-horizon attack, but also a leap forward in attack accuracy. Moreover, this also makes up for the shortcomings of night battles, making night artillery battles easier.

Just follow the radar data and fire, and that's it! It's so easy to defeat the enemy, all you need is the radar to not malfunction......

As for the other side of the world, there is such a country, what is the purpose of finding a group of far-sighted night owls to practice artillery warfare, Ruetjance said that he really can't understand.

According to Lütjans's plan, and the Führer's idea, the future German fleet would have the most advanced carrier-based aircraft to disintegrate its opponents at ultra-long distances with air supremacy.

When the opponent approaches the periphery of the fleet, the battleships, equipped with radars and giant guns, will act as frigates of the aircraft carrier to fulfill their own defense duties.

At that time, the battleship will no longer be a decisive battle at sea, but an oversized frigate of an aircraft carrier.
