"Candail shells?" Conrad shook his head.

Although Qin Chuan's suggestions have always been very constructive, such as the rocket launcher, ME163, etc., this time... Conrad believes that Qin Chuan is a layman in the tank.

Because the German military industry has studied various shells, it can even be said to have to turn the shells over and over, but in the end it has failed to make any tricks.

"Yes, shells!" Qin Chuan explained while drawing on the paper: "This shell is fired with a smoothbore gun, and its bullet body is a slender rod shape. We know... The shell is only affected by gravity and air resistance in the air. The slender rod shape can minimize its resistance. Launching with a smoothbore gun can increase its initial velocity so that it can obtain kinetic energy as much as possible. At the same time, because the warhead is sharp and has a small area of ​​force, it can have great penetration when hitting the tank armor!"

Hearing this, Conrad immediately showed a cautious look on his face, because the few simple words Qin Chuan said proved that he knew nothing about tanks at least about shells.

Conrad glanced at Qin Chuan unexpectedly, and then said to the drawings: "But such a slender rod-shaped shell... how can we use artillery to fire it?"

"We can make an ammunition holder for it!" Qin Chuan replied: "This ammunition holder is divided into two halves, the size is the same as the diameter of the gun. The long rod ammunition body is sandwiched in the middle. After firing, the ammunition holder will automatically separate from the long rod ammunition body due to air resistance!"

Hearing Conrad's eyes shining: "Lieutenant Colonel, but a long pole body like this cannot maintain its stability during flight..."

Before Conrad finished speaking, Qin Chuan added a few strokes after the long pole body and said, "This is simple, we can add four cross-tails to it!"

This kind of armor-piercing projectile will be shelled and can fly stably in the air with its tail wing, so it is called a tail-piercing projectile.

Conrad was stunned when he looked at the pictures on the paper. He looked up at Qin Chuan and looked at the drawings again and again, and said in disbelief: "Lieutenant Colonel, are you sure such a shell can work?"

"Why don't you try?" Qin Chuan said.

"In principle...it seems to work!" Conrad nodded while looking, "Why didn't we expect to use this method? It's like an arrow, Lieutenant Colonel... You made a shell into an arrow, but this arrow is an iron arrow, and it is fired with a cannon. It will shoot at the enemy's tank and then pierce a hole in the tank armor..."

Then Conrad turned his gaze to the sharp arrow and continued: "It is conceivable that after the smoothbore gun fires it, all the kinetic energy will be applied to the arrow, and its ability to pierce the enemy tanks' armor will be unparalleled!"

Conrad is right. Modern tail stable shell-out armor-piercing shells can penetrate hundreds of millimeters at any time. Modern German 120MM tank gun can penetrate 600MM of homogeneous armor at a distance of 2 kilometers.

At this time, the front armor of the "Tiger" was only 102MM, and even the most bulky "Rat" had only 240MM armor. The thickness of these armors was covered with scum under the "tail stable shell-out armor-piercing bullet".

"This shell needs a very hard material, does it?" Conrad asked.

"Yes!" Qin Chuan replied: "Of course, and because it penetrates the target armor at an extremely high speed, it must be able to withstand high temperatures!"

"Tungsten core armor-piercing bomb!" Conrad replied.

This is technically not difficult for Germany, because German tanks have generally equipped tungsten-core armor-piercing bombs, and as mentioned earlier, the HS129 fighter jet developed specifically for enemy tanks... In order to improve the penetration of its anti-tank gun, it is also equipped with tungsten-core armor-piercing bombs.

The problem is that tungsten is a shortage of minerals in Germany. Coupled with the blockade of the Allied forces, Germany does not get much tungsten, mainly imported from Spain.

"But!" Conrad said: "If it really works, it's worth it!"

Of course it is worth it. An armor-piercing projectile that can penetrate any enemy tank, and it also has a long range and extremely high accuracy... This allows German tanks to destroy almost all opponents.

Finally, Colonel Conrad sighed and said, "You convinced me, Lieutenant Colonel. If this shell... can easily penetrate several hundred millimeters of thick armor, then it is indeed meaningless to develop thicker armored tanks, because they will be like we said before: under its attack, there is no difference between thicker armored heavy tanks and thinner armored light tanks!"

"That's what I want to say!" Qin Chuan said: "So..."

"I know, Lieutenant Colonel!" Conrad Yang said with the drawings drawn by Yang Qinchuan, "If this shell is proven to be effective, then all heavy tanks will stop researching. We will not be stupid enough to pile resources on some meaningless projects. We need resources now!"

"That's good!" Qin Chuan couldn't help but breathe a sigh of relief when he heard this.

"I have a problem, Lieutenant Colonel!"

“What’s the problem?”

"If you keep putting this idea..." Conrad raised his head at the drawings: "I mean, you keep it in your heart instead of saying it out, then what will happen in the end?"

Qin Chuan knew what Conrad said:

If Qin Chuan didn't say it, then Germany would not be able to produce it. If it doesn't produce, it would be impossible to put it into use on the battlefield. If it doesn't put it into use, it means that the enemy does not know the existence of this thing, of course it is impossible to imitate it.

Therefore, in the end, Germany does not need to worry about the problem of "stable tail wing to release shells and armor-piercing bullets".

"I don't know, colonel!" Qin Chuan said: "Maybe, one day the enemy will think of it and use it on the battlefield first, and then we will regret it!"

Conrad nodded in agreement.

Qin Chuan did not lie because the British first used shell-out armor-piercing bombs (APDS) on 6-pound anti-tank guns in October 1944, and then successively used them on 17-pound anti-tank guns and Firefly tanks.

The difference is that (APDS) is fired by a rifled gun, so the accuracy and penetration depth will be much different.

But even so, it can penetrate 192MM of armor at a distance of 1,000 meters, and the German "Tiger King" had no advantage at that time.

But Qin Chuan has changed this, so none of this will happen.

At least Qin Chuan believes that the "rat" tank that cannot play a role in actual combat will not appear again.
