Before the outbreak of World War II, the level of tank development in various countries was basically still in the early stages. The protection standard of heavy tanks was in the 40mm-60mm range, the tonnage was only about 25 tons, and the main gun caliber was 47mm, so it could be called a heavy tank.

, the most famous one is the legal B1 tank.

"General, people from Krupp and Siemens are already on their way." After the report, the young officer stepped forward and reminded Guderian.

"Go down." Guderian nodded.

The young officer did not stop and turned around to leave.

"Everyone, you have heard the professional evaluation results and performance parameters of Y-type armor steel. I believe you already have an understanding. We don't need to worry about whether Y-type armor steel was invented by a Chinese. What we need to focus on is,

Do you agree to this deal? Y-shaped armor steel will eventually be manufactured and installed on our tanks!"

When the young officer walked out of the conference room, Guderian looked at everyone and said seriously: "I will personally express my attitude first. I agree."

"I agree!" In an instant, several voices with different accents mixed and blended into one.

Every soldier present raised his right hand, and no one had any objections or objections.

be opposed to?

Twenty-four cutting-edge mechanical processing equipment were exchanged for a top-level protective material formula. Really, everyone present almost shouted in their hearts, this kind of transaction is so damn profitable.

"It seems that everyone has the same idea in this regard. It can be seen that the penetration resistance of Y-type armor steel is very good. We need to immediately develop an improved model of Panzer IV tank based on Y-type armor steel. This new Panzer IV tank

The tank will use 40mm Y-shaped composite armor, and the actual protection can reach 56.8mm. Moreover, I think a 75mm caliber main gun can be added to maximize the firepower and protection while the mobility is slightly reduced.

, completely crush the enemy!" Guderian showed his iconic smile, then looked at everyone and gave his new idea: "It's called Type 4 D."

The words are impassioned and full of imagination.

Hearing about this new model of Panzer IV, all the soldiers present were excited. They all nodded in agreement and were full of expectations. With the new armor steel, it is natural to launch a new model of Panzer IV.

With slightly reduced mobility, firepower and protection will be maximized!

This is how the Y-shaped armor steel reflects on the tank. When the armor can improve protection without increasing weight, the firepower can be increased again.

The emergency meeting continued, and soon after, representatives from Siemens and Krupp rushed to the conference room to conduct a division of interests.

The people on the technical team come from Krupp, and as a giant in the steel industry, Krupp is eyeing the Y-shaped armor steel formula.
Chapter completed!
