Deathly silence!

Herman's mind seemed to have been hit by a heavy bomb, buzzing, completely losing his logical thinking and thinking ability, and almost going blank.

What did he hear?

Equivalent to 234.6 mm above the head?

The first down is equivalent to 181 mm?

Herman really doubted whether he had heard correctly.

The concepts of actual armor and equivalent armor are easy to understand, but Herman never expected that the protective power of this tank body would be so terrifying.

"Of course, this is just theoretical data. We need to verify it through experimental testing. Let's continue testing." Guderian said with a smile, not paying attention to the shocked Hermann beside him.

After hearing this, Herman finally woke up and took a deep breath: "General, there is no more powerful artillery than the 50mm anti-tank gun in the testing site. How should we test it?"

"When I came here today, I pulled an FK36 anti-aircraft gun. Krupp made a batch of tungsten core armor-piercing bullets and used it for testing." Guderian said.

"General, isn't this an anti-aircraft gun?!" Herman was dumbfounded when he heard these words.

Anti-aircraft guns as anti-tank guns?

He has never seen this kind of operation, no, he has never thought about it.

"Yes, but the FK36 anti-aircraft gun has all the characteristics of an anti-tank gun. If nothing else happens, this anti-aircraft gun is very likely to become the main anti-tank gun of the National Defense Forces in the future." Guderian nodded.

Silent, at a loss, and with a hint of expectation, Herman felt complicated. He shook his head helplessly, turned around, and conveyed the order below.

Although the use of anti-aircraft guns as anti-tank guns did surprise him, compared with the terrifying protection of this new Henschel tank, this method seems to follow a certain logic.

Can't wear it?

Then increase the diameter and magnification until it is penetrated.

But the question is, in the active artillery series of the National Defense Forces, is there really any artillery that can achieve 230 mm penetration?

Hermann couldn't answer this question. He didn't even know whether the 88 mm caliber FK36 anti-aircraft gun firing tungsten-core armor-piercing projectiles could penetrate the body of this new tank...

The 234.6 mm front armor is really terrible.

Guderian's orders were continuously conveyed, and the FK36 anti-aircraft gun team immediately entered the deployment state, and this order directly caused a sensation among everyone at the tank testing site.

88 artillery fire?

No one expected that today's vehicle body protection test would reach such an extent. The two anti-tank guns equipped at the tank test site could not pose a threat to it, and the 88mm anti-aircraft gun had to be used as an anti-tank gun.

The situation is exaggerated to the point of making people feel magical.

The 50mm anti-tank gun withdrew from its firing position, and the artillery team attached to the test site stepped aside. This shooting mission was performed by the anti-aircraft gun team.

Fifteen minutes later, the FK36 88mm anti-aircraft gun was deployed. The huge barrel was leveled, aimed at the target ahead, locked on the new tank body, and the 88mm tungsten core armor-piercing projectile was loaded into the chamber, completing all preparatory work for shooting.

The whole place was silent. Whether it was the experimenters at the tank test site or the artillery team that had previously been tasked with the test, they stared at the 88 gun in the firing position, pinning their hopes on the other party.

Whether it can penetrate the frontal armor of this tank depends on this large-caliber anti-aircraft gun.

This is the last hope for everyone at the tank proving ground.

Because, apart from the 88mm anti-aircraft gun, the only type of artillery currently in service in the National Defense Force that exceeds this caliber is the large-caliber howitzer.

You can't just pull a 150mm howitzer over and blast it, right?

Howitzers bombard tanks. This kind of test does not have any practical significance or reference value.

"Fire!" The anti-aircraft gunner looked serious and gave the order to fire without hesitation.

"Boom!" In an instant, a deafening sound of artillery was heard. It was huge and loud, like thunder. The flames from the muzzle stirred up a cloud of dust. The artillery shells shot out like arrows, spanning a distance of one thousand meters.

, accurately hitting the tank body.

Cannonballs weighing several kilograms contain a high amount of kinetic energy, and their own kinetic energy pours out at the moment of contact. The carburized hardened steel on the armor surface on the front of the car body is far from being able to withstand such a degree of blow, and it quickly breaks through and loses its function as the main armor.

The Y-shaped armor steel made of the material comes into play, constantly consuming the kinetic energy of this 88mm tungsten core armor-piercing projectile.

After one hundredth of a second, the entire shell stopped moving forward, and seemed to be embedded in the armor like a shining diamond.

Two experimenters in the armor testing area quickly stepped forward and quickly collected the test results.

"What's the depth of penetration?" Herman couldn't wait any longer this time. He immediately picked up the phone and called the armored area and asked impatiently.

"Report to the colonel, the actual penetration depth of the 88mm anti-aircraft gun is 42mm, and the equivalent penetration depth is 115mm." On the other side of the phone, the bitter and helpless voice of the experimenter came: "The 88mm anti-aircraft gun still cannot penetrate."

Unable to penetrate!

This result means that the Wehrmacht does not have the ability to destroy or threaten this tank.

Hearing this, Hermann was completely desperate. He felt powerless in his heart. He put down the phone and turned to look at Guderian helplessly: "General, there is still no penetration. The actual penetration depth is 42 mm. The equivalent penetration depth is 42 mm."

The depth is 115 mm. I think this is the surprise you are talking about. According to all the current test results, the army does not have any threat to tanks of this level above one thousand meters. What should we do?”…

One thousand meters!

This is the mainstream distance given by Guderian for tank concentrated fire operations. Often when this distance is reached, tanks can open fire and attack enemy tanks.

"Haha, you should be happy, because this is what we have researched. If nothing else, this is the 35-ton tank solution I want. Herman, shorten the test distance to 500 meters, ten times

Shoot, let me see if the 88 gun can pose a threat to this tank at a distance of 500 meters." Guderian let out a hearty laugh, feeling extremely comfortable, and then arranged.

500 meters, ten shots!

In one word, boom, keep booming.

Faced with Guderian's request, Hermann could only comply and make arrangements immediately.

Not long after, a special tractor came rushing over, drove into the armor testing area, and pulled the new tank body forward to the 500-meter target point.

"boom!"

"boom!"

"boom!"

The 88mm anti-aircraft gun that had completed the preparations fired continuously, and the tungsten core armor-piercing projectiles flew at high speed and hit the armored area on the front of the tank body hard.

However, all this is in vain.

Each shelling was deafening, and the metallic sound of the shells hitting the tank armor penetrated into the souls of everyone at the tank testing site. The imaginable penetration scene still failed to materialize.

despair!

If you encounter such a tank on the battlefield, you can only describe it as despair.

A total of ten shots were fired in the 500-meter test, with an average actual penetration depth of 46.5 mm and an average equivalent penetration depth of 128 mm. This was significantly improved compared to the 1,000-meter test, but it was still unable to penetrate the frontal armor of the new tank.

"Put it in to a hundred meters and shoot dozens of times." Guderian looked calm and continued to order.

As the supreme commander of the test site, Hermann's hands were trembling slightly and sweat broke out on his forehead as he silently conveyed Guderian's orders.

What is the concept of a distance of one hundred meters?

This is no longer just attaching a bayonet to a cannon, it's simply putting a cannon in someone's mouth and firing!

But whether it can penetrate the frontal armor of the new tank body is still a question mark.

"boom……"

The tank proving ground resounded with deafening shelling.

One minute later, with the end of ten consecutive rounds of firing in the 100-meter test, a test result that made the Berlin Tank Proving Ground despair was born.

In the 100-meter protection test, the average actual penetration depth was 80 mm, and the average equivalent penetration depth was 140 mm.

Experimental result - unable to penetrate!

After receiving the final test results, Guderian smiled as happily as a child. The reality gave him an unprecedented surprise. The combination of tilted armor design and Y-shaped armor steel will form the cornerstone of the Wehrmacht tank force.

Henschel's thirty-five-ton tank plan is indeed excellent, but with the inclined armor design and Y-shaped armor steel, tanks with more powerful performance can be developed in the future.

"Leinmetall is ordered to develop a new large-caliber anti-tank gun based on an 88mm anti-aircraft gun. The core requirements are as follows: the penetration power at a distance of 1,000 meters must reach an 85mm normal angle of 60 degrees, with high maneuverability and high precision."

"Krupp is ordered to completely suspend the production of Panzer IV tanks. Y-type armor steel and carburized hardened steel must be used as the main armor materials to improve the protective power of Panzer IV tanks."

"Get me a car, I want to see the head of state right away."

…

No one knows about the testing of new tanks in Germany, and the world continues to operate according to its original rules.

At dawn, there was a hazy drizzle in the sky. On the eastern outskirts of Yancheng, a Dodge truck drove on the hard concrete road and headed towards Liushugou.

"Chief, we have arrived in Yancheng." In the carriage, Lu Junyu reminded Yu Hua who was lying in the carriage.

"It's not easy. I'm finally back. After the construction of Shenmu and Yanma Highways is completed, the schedule of Yanyu Highway will also be increased. My back is sore from sitting all the way." After hearing this, Yu Hua cheered up a little and rubbed his hands.
Chapter completed!
