"Why?"

The lieutenant general accentuated the tone:

"Tell me about the specifics."

The Germans' refinement of tank No. 4 had clearly reached its limit.

According to the information transmitted back by the intelligence officers, the Germans had not long ago tried to increase the firepower of the No. 4 tank by installing the turret of the No. 5 tank on the No. 4 chassis, but in the end it failed.

After that, the Germans abandoned the upgrade of the No. 4 tank and turned to the development and improvement of the new tank, the No. 5 tank, the Leopard medium tank, the No. 6 tank, the Tiger heavy tank, and so on.

But now, a new type of No. 4 tank has appeared, and its comprehensive combat capability has been greatly improved.

Let the lieutenant general be hard to believe.

At the present point of the war, the scientific and technological potential of all countries has been brought into full play, and it is no longer possible for a sudden major technological progress, and it is becoming more and more impossible for a certain design to greatly improve the performance of weapons.

Right now. The development of any weapon is gradual.

The design of the No. 4 tank was finalized in 35 years, and although it has been improved, it is limited by the technology of the time, the chassis, armor, suspension, engine, and overall tonnage are limited by the upper limit of improvement.

In comparison, the 40 tank, which was finalized only in 34 years, has significantly more improvements.

Unless the Germans made explosive and drastic progress in a certain basic technology, basic material technology, engine technology, artillery technology, etc., but this is obviously impossible.

He knew very well how difficult it was to advance these technologies.

"The report hasn't been sorted out yet."

The major general in charge of the test said:

"But the No. 4 tank captured this time has greatly improved its mobility, protection, and firepower."

"Tell me about it!"

The lieutenant general's expression was grim.

Could it be that the Germans have made great technological progress?

This is not good news.

"In terms of the basic frame, the new tank is not significantly different from the previous one."

The major general wiped his forehead:

"It is still a small load-bearing wheel, torsion bar suspension, vertical armor layout, 80 mm front armor thickness, 48 times the diameter of the 75 gun, and the full weight is also about twenty-seven tons (including fuel and shells, members)."

Hearing this, Zhong's face was even more puzzled.

These things haven't changed, even the artillery is still the same artillery, so why is it said that the combat effectiveness has increased dramatically, even twice as much.

Major will continue to say:

"But the overall internal structure is very different from the previous No. 4 tank, almost equivalent to a brand new tank."

"The engine, from the original 300 horsepower gasoline engine to the 330 horsepower new diesel engine, after testing, the new diesel engine in the case of a 10 percent increase in horsepower, there is no change in volume."

"And."

"After 10 hours of high-intensity continuous driving tests, the fuel consumption per unit horsepower of the new diesel engine is 23 percent lower than that of the diesel engine of the T34 main battle tank, and there were no failures during the period."

"The maximum torque is also more than twice as large as that of the previous gasoline engine."

Hearing this, the lieutenant general's mouth opened and his pupils suddenly contracted.

How is this possible!

The diesel engine itself is much heavier than the gasoline engine because of its compression combustion principle, and the German engine technology is very advanced, and the gasoline engine of the original No. 4 tank has a compact structure and a high power-to-weight ratio, which makes him blush.

Now, it's actually a diesel engine of the same size and weight, with more horsepower.

Not to mention the low failure rate, low fuel consumption, and greatly increased torque.

Equipped with this engine, the No. 4 tank can improve its maneuverability by at least 20 percent, and the passability brought by high torque can be improved even more in difficult terrain.

Major will continue to say:

"The gearbox is also a new model, smooth shifting, quick response, small size and light weight, the turret is equipped with a servo motor, and the rotation speed is increased by 28 percent."

"The thickness of the armor has not changed, but the armor steel is better, and after testing, the defense capability has been increased by 13 percent."

"The artillery has not changed, but all the shells are new tungsten alloy armor-piercing shells, the armor-piercing ability has been increased by 17 percent, and the accuracy of the artillery has been improved."

When the data came out, a drop of cold sweat began to appear on the lieutenant general's forehead.

Off-road mobility is increased by more than 20 percent, endurance by more than 30 percent, defense by 13 percent, armor piercing by 17 percent, and turret rotation speed by 28 percent.

No wonder it was said before that it was a doubling of combat capabilities.

Although there is not much data in this item, the tank is a comprehensive weapon platform, which is essentially the integration of firepower, mobility, and defense.

At present, the protection, firepower, and mobility of the new No. 4 tank have all been improved, and the improvement is not small, it can be said that this is a new tank that is completely similar to the No. 4 tank, but the performance has been greatly improved.

Thinking about it, the lieutenant general's cold sweat began to slide down drop by drop.

"Among them, it seems that the new fire control system has the biggest improvement in combat effectiveness!"

The Major General's words once again made the lieutenant general's pupils shrink.

"After testing, a skilled car crew found that the speed of capturing, identifying targets increased significantly, and shooting was also faster than before."

"I see."

Hearing this, the lieutenant general rubbed his forehead, which had already been soaked with sweat, and his face was as solemn as the bottom of a pot:

"Get the report out as soon as possible."

The lieutenant general sighed deeply in his heart.

It is not clear how the Germans suddenly came out with so many tanks, so many weapons and ammunition, and how such a huge number of tanks, armored vehicles, and supplies got to the front line.

It was found that the performance of the new German tank was very good.

The curb weight of 27 tons and the power system of the new diesel engine gearbox make this tank very passable, most of the bridges can be directly passed, and the railway transportation is also simple and fast.

Even more terrifying is its quantity.

At present, there are more than five thousand of them, that is, those that appear in battle.

Combined with the advantages of the Germans' original tank crew, it would bring great trouble to the front-line battles.

"I will report to Comrade Stalin as soon as possible."

The lieutenant general's tone was low.

It's not a good job.

"Yes."

Despite having a pair of panda eyes and bloodshot eyes, the major general still nodded heavily:

"I've got people to hurry, and in an hour, the report will come out."

·······

Meanwhile.

Cherbourg.

"Quick-drying cement."

Rommel looked at the fortress group in front of him, and his tone was full of emotion

"Sure enough, technology is an important factor in determining the direction of war."

Thanks to the large-scale construction before the war, as well as a large number of works during the war, Germany had a large number of engineers, construction technicians, a large number of prisoners and the population of the occupied areas, and there was no shortage of labor at all.

When there is enough food, the labor force can also be fully utilized.

Coupled with fast-drying cement and various construction machinery, in just a few days, around Cherbourg, a group of solid fortifications rose from the ground.

Even the 305 shore defense guns were built several pieces.

As for the anti-aircraft towers, because the amount of work is so large, even if the engineers who have built them before are transferred, it will take at least a month to complete, and now there are only a few anti-aircraft fortresses in the Cherbourg area.

Equipped with four 40-mm anti-aircraft guns, the one-and-a-half-metre concrete anti-aircraft fortress was also prevented from being subjected to massive bombardment in the Cherbourg area.

"Indeed."

Catherine looked at the scene in front of her and said the same emotion.

They were able to complete the current fortification complex in Cherbourg in such a short time.

A chain of concrete bunkers, ten 12-inch shore defense gun fortifications, fifty-seven anti-aircraft fortresses armed with quadruple 40-mm anti-aircraft guns, more than fifty turrets with 150 shore defense guns.

The main thing is not tens of thousands of skilled workers, as well as military personnel, hundreds of engineers, a large number of construction machinery, incredible fast-drying cement.

Rather...

Catherine looked behind Cherbourg and moved the simple warehouse.

This simple warehouse of more than 5,000 square meters.

The warehouse of more than 5,000 square meters is not small, and many large companies do not have warehouses of such a scale, but compared with the current fortification complex in Cherbourg, there are six air defense towers that are about to be built.

This warehouse is pitifully small.

But at present, all the building materials, food supplies, weapons and ammunition, machinery and equipment are from this warehouse.

And all kinds of materials and equipment are constantly popping up.

"If we can master this technology..."

Kesselring let out a long sigh.

If the empire can master this technology, it will really win this war, instead of being used as a gun now.

"I asked when I was drinking with those guys."

Rommel smiled and said:

"What quantum technology is supposed, and what gravitational wave technology is, specifically, they shouldn't know..."

"Quantum technology? Gravitational wave technology? ”

The corners of Kekesselin's mouth twitched.

He had never heard those two words before.

"Next, it's up to you."

Kesselring said suddenly.

"What's your new mission?"

Rommel asked suddenly.

"Bomb America."

Looking around, Kesselring suddenly whispered.

"Huh?!"

······

Heyuan County.

Separate regimental airbase.

"This new thing, big enough."

In the airport, in a huge closed hangar, Li Yunlong's mouth was open.

He had an airplane in front of him.

Slender cylindrical fuselage, flat cantilever upper wing, wing box engine, three-point landing gear.

The most eye-catching thing about this plane is its size - a wingspan of more than 70 meters, a length of nearly 50 meters, and a height of 14 meters, which is nothing more than a large supermarket in Heyuan County.

Of course, in addition to the size, there are a few other attractions – a small cart-style landing gear the size of a truck, and six huge propellers behind the wings.

"Hey, hey, hey..."

Then, Grand Master Li showed a sinister smile.

"How many were given to them?"

Zhao Gang, who had just come in, asked.

"One hundred... Eighty. ”

Li Yunlong slowly raised one finger, and then slowly raised a second finger.
