"Let's ......" Qin Chuan paused, and said, "Let's call it a proximity fuse shell!" ”

"Proximity fuse shells?" The officers were confused, because no one had heard of such shells.

"Let's put it this way!" Qin Chuan said: "The other parts of this shell are no different from ordinary shells, and the difference lies in the fuse...... Simply put, the fuse will automatically explode when it gets close to the target! ”

The officers listened confused, because they did not realize the significance of this "automatic explosion".

Raeder was also a little unimpressed at first, but after thinking about it carefully, he looked at Qin Chuan with wide eyes: "You mean, this kind of shell doesn't need to adjust the delay time?" ”

"Yes, sir!"

"He'll automatically detonate when he's closest to the target?" Raeder asked again.

"Yes, sir!"

At this time, the officers heard the power of this, you must know that the kind of time-delayed fuse shells need to manually calculate the time and then manually adjust the duration, which is not only slow and easy to lose fighters, but also because of the tension on the battlefield.

If there is a kind of artillery shell that does not need to calculate the delay time, and at the same time does not need to be adjusted, it will greatly increase the hit rate of the anti-aircraft gun and increase the rate of fire of the anti-aircraft gun (note: saving the time of calculation and adjustment), which is undoubtedly a qualitative improvement for the improvement of the anti-aircraft gun's air defense capability.

Historical facts have also proved that such proximity fuse shells are useful...... Historically, it was the United States that produced the shell two years later and used it in the Pacific theater.

And the statistics show that it takes an average of 2,000 rounds for ordinary artillery shells to destroy an enemy aircraft, while only 500 rounds for a proximity fuse.

Regardless of the fact that this will reduce the pressure on logistics, the ability to quickly destroy enemy aircraft on the battlefield means that the pressure will be reduced, and the balance of victory will soon tip in one's favor.

"How?" Raeder asked.

"It's kind of like our radar!" Qin Chuan said: "I rescued a wounded radar soldier and learned about it during the conversation...... The reason why radar can detect enemy aircraft is that it emits an invisible and inaudible ultrasound wave, which is reflected back when it hits an enemy aircraft, so we can calculate its distance and direction and know its location! So I thought...... Why can't we put a miniature radar in the fuze, which is constantly emitting ultrasonic waves to detect the distance between itself and the target, you can imagine...... This distance is constantly decreasing, decreasing, and then at the moment when the distance is transformed from decreasing to increasing, it 'expands' ......"

Qin Chuan made an explosive gesture.

The officers looked at Qin Chuan in a daze, no one expected that a lieutenant would have such an unbelievable idea.

"That sounds ...... It's technically possible! Raeder said, "Because we have radar technology, we can also make shells!" ”

"But our radars are huge!" Major General Oxter said.

"That's a radar for monitoring targets at long distances, that is, tens or hundreds of kilometers away!" "If it's just a dozen kilometers, a few kilometers, or even a few hundred meters," Raeder said...... It's entirely possible to do it small! ”

Then Raeder glanced at Qin Chuan again and said, "Of course, this is only possible, we still have to ask the R&D department for the specific situation!" ”

Then Raeder became interested, and he couldn't even wait for the staff officer to ask, and personally went to the communications corps to contact the Germans.

Taking advantage of this time, Colonel Slane lowered his voice and said: "Marshal Raeder and Colonel Conrad are comrades-in-arms, I think he is the one he contacted Colonel Conrad!" ”

Qin Chuan couldn't help but let out an "oh", no wonder Colonel Slain mentioned Conrad just now.

Colonel Slain guessed correctly, the person Raeder contacted was Conrad.

"Colonel!" "I've met a guy here, his name is Flick, he's a lieutenant, have you heard of him?" ”

"You're talking about 'Legendary Sergeant'?" Conrad said, "Yes, of course, but the last time I saw him, he was a second lieutenant!" ”

"Hmm!" Raeder said: "He was promoted because of the capture of the warship of the French!" ”

"Wow!" Conrad said: "He actually captured the warships of the French, how many did he capture?" ”

"To be exact......" replied Raeder, "a whole fleet, 78 ships!" ”

Conrad on the other end of the line was speechless in shock.

"You're not kidding me, are you, Marshal?" Conrad said.

"That's why I'm in this hellish place in Africa, do you think I'm joking?" Raeder said: "But the Führer did not publicize it for the time being, you know, it is not good for us to overstimulate the French!" ”

"I understand!" Conrad laughed on the other end: "This 'legendary sergeant' is really amazing. But Marshal, you don't contact me just to tell me this! ”

"No!" "He had an idea, an innovation in terms of shells......

"Great!" Conrad on the other end of the phone exclaimed excitedly: "What kind of innovation? Tell me! ”

"You haven't even heard me yet!" Raeder asked, confused, "And you think it's 'fantastic'!" ”

"Please, Marshal!" Colonel Conrad said: "That guy is a genius, my phone is open for him twenty-four hours a day, and I even arranged for three people to take turns guarding his call for fear of missing it, but he never called!" ”

Raeder was so surprised that he didn't close his mouth for a long time, and after a while he replied: "Well, he's talking about proximity fuse shells, I wonder if it's feasible, how long it will take to mass produce if it does, and how much it will cost to produce......"

Ten minutes later, Raeder was back at headquarters.

Seeing Raeder's serious expression, the officers thought that things had encountered difficulties, but Raeder said: "Lieutenant, they said that you have solved a long-troubled problem, and the R&D department has always wanted to develop a proximity fuse like you said, and they thought of light, sound, magnetism, etc., but the effect was not ideal, because the experimental effect was not good, so it was not put into actual combat, and the way of working you said...... They think it's a good idea, but it needs to be verified if it's feasible! ”

The officers couldn't help cheering, which basically affirmed Qin Chuan's statement.

"Well done, Lieutenant!" Colonel Slane patted Qin Chuan on the shoulder.

"Because not sure if it's going to work!" "So you can't hope too much for it!" Raeder said. ”

"Yes, Marshal!" The officers responded one after another.

However, Qin Chuan knew that it was feasible, because it was a real thing in the near future, and with Germany's industrial capacity, it would not be difficult to turn it into reality after knowing this idea.
