Chapter 120: Qin Guan's negligence

Most of the tanks of the Han country were inherited from the Xiong country, taking the route of medium tanks. One of the big points is the limitation of bridges.

In the south of Han, the water network is everywhere, and bridges are needed to pass everywhere. If the bridge's capacity is not enough, the tank will be pushed up, and the bridge will be crushed at any time.

Therefore, under such circumstances, Han State did not dare to develop heavy tanks.

Now, large-caliber artillery, high-horsepower engines, and heavy armor, once assembled, must weigh more than fifty tons. Under such circumstances, can the country accept it? Can the army accept it?

After all, the official indicators of the new tank have not been released yet. Everything is pre-research. It is only pre-research on each subsystem. In this case, what standard should you design according to?

You can discuss it with Qin Guan.

Thinking of this, Zhu Lao said: "Qin Guan, do you think the weight of our new generation tank is the most suitable?"

"50 tons or more." Qin Guan said: "If you want to achieve a compromise between firepower, protection, and maneuverability, 50 tons is the most basic figure. With the continuous development of armor, this weight will increase, and even It reaches 58 tons, 68 tons. If it is lower, what is the difference between it and 59 on the battlefield?"

A word from Qin Guan gave Mr. Zhu a great reminder.

Yes, if you are only limited to the 59 tanks with more than 30 tons, you will never be able to make progress. If you want to develop, you must increase the weight index. When it is expanded to 50 tons, everything will be easy. Up.

A 1500-horsepower engine to drive a 50-ton tank should be more than enough.

"However, our operations in the south will be greatly affected." Zhu Lao continued, this question seemed unsolvable.

"Our tanks were not originally prepared for the South." Qin Guan said: "What's in the South? Right now, light tanks are enough for border wars. Will our main battle tanks be needed?"

It is impossible to fit all terrains. If a conflict breaks out in the south, it will be impossible for one's own main battle tank to play.

"If we want to develop new tanks, we should aim at an enemy, the bear country in the north!" Qin Guan continued: "Our combat area will be in the grassland. The vast expanse of grassland will be the stage for our tanks. In this case, the tank is more arrogant. What's the disadvantage?"

In terms of combat objectives, our new tanks were not prepared for the South at all, but for the North. Now, the bear country in the North has been eyeing it for many years. In times of crisis, even the capital is ready to move.

With a few words, Qin Guan relieved Zhu Lao's worry. Yes, I will explain this point when I meet again at the higher-level meeting.

It is impossible to satisfy both the South and the North. This is the current situation. The greatest threat must be targeted, the bear country in the north!

Now even the introduction of a 105mm gun production line has to be sneaky, just because it is afraid of irritating the bearers, the new tanks developed are based on the bear country.

"Furthermore, our country has begun to enter a new era. With the development of time, our construction in the South will also change with each passing day. Buildings will rise from the ground and bridges will cross the river. So, in a few years, The bridge in the south is enough to withstand the passage of our tanks, so we don’t need to worry about it."

Qin Guan has more confidence in the construction of the motherland, and the title of infrastructure madman is not for nothing.

Without increasing the self-weight of the tank, nothing can be developed, and a simple self-weight must not limit oneself.

"What about our tank guns?" Zhu Lao continued: "Now, the tanks of Hansi and other countries have a caliber of 120 mm, while those of Xiong have a caliber of 125 mm. Which caliber do you think is better?"

"The bigger the better." Qin Guan almost didn't think about it. In his mind, he was still thinking about the mighty and majestic appearance of the 99 tanks of later generations.

"Strange, how come this shell is separated?"

At this moment, a technician removed the shells from the tank.

The shell is divided into two parts, the cylindrical one is the propellant, and the pointed one is the warhead. These two parts look a little strange.

When he saw this ammunition, Qin Guan's mind suddenly reacted, not good, he seemed to have forgotten something.

Now, relying on the knowledge of the previous life and the system in his brain, it seems that he is already omnipotent, but he still has a lot of negligence.

For example, the difference between full and sub-package.

Hans’s 120mm tank gun uses full-loaded ammunition. The warhead and propellant are together, while Xiong’s 125mm gun is in two separate parts.

When reloading, the Hans country only needs to load it once, and the bear country needs to load it twice.

Of course, this one is not a big deal, because the bear country's tank is an automatic loader and does not require human operation.

However, there will be a big problem here, that is the effectiveness of the armor-piercing projectile!

Tanks are the king of land warfare and are meant to destroy enemy tanks, so for tanks, most of the high-pressure tank guns fired armor-piercing shells.

The slender and long kinetic energy bullet core is used to destroy the enemy tank. In addition to the material of the bullet core itself, the other more important thing is the aspect ratio!

The ratio of the length and diameter of the bullet core, the larger the data, the better the armor penetration performance of the bullet.

The full-loaded ammunition, because they are together, the core can extend to the end of the propellant, which is equivalent to the length of the entire shell.

For the divided ammunition, the warhead is only half its length.

Therefore, no matter how it develops, a sub-loaded warhead will not have a full-loaded warhead with high armor-piercing ability!

Thinking of this, Qin Guan's head is already big for a while. For the armor-piercing projectile, in addition to the caliber of the artillery, it also has a lot to do with its structure. This congenital defect is almost the death of the 125mm gun. Point!

Why not design it as a single ammunition? Because the automatic loading machine does not have that ability, it can only be loaded separately.

Change to manual loading? For Westerners who are tall and majestic, loading 120mm cannonballs is the limit. If the 125mm cannonballs are integrated and loaded by Han Chinese who are not tall, it would be a tragedy.

Qin Guan thought about it for a long time, and it was no longer as smooth as before, and Zhu Lao also saw the strangeness of Qin Guan and asked, "What's wrong?"

"I suggest that we get a Leopard-2 prototype and compare it with this T-72 prototype. Through comparison, we can choose the most suitable tank for us." Qin Guan said, "The tank The selection is of great importance, and we must not be hasty."
