Chapter 374： Compromise to cost

Tank guns depend not only on the caliber, but also on the length of the barrel. You must know that the longer the length, the longer the gunpowder gas will last in the barrel, and the higher the initial velocity of the shell.

Therefore, the current 75mm long-barreled tank gun of the Panther 3 is almost the same as the 88mm tank gun of the upcoming Tiger.

Hearing this, Cyric thought that Kneeberkamp was going to suggest to use the 75mm tank gun instead of changing the 88mm tank gun in order to unify the caliber. He didn't expect that his proposal would be the other way around.

"Therefore, we suggest that the Panther 3 tank we are now producing can also be replaced with this 88mm tank gun." Kneibokamp said.

Hearing Cyric for a moment: "Why?"

"Cost and output." Kneberkamp said: "The long-barreled 75mm tank gun is quite complicated to manufacture and has a high rejection rate. The short-barreled 88mm tank gun is easy to manufacture. According to statistics Now the cost of a 75mm tank gun is equivalent to two 88mm tank guns."

In an instant, Cyric understood something.

After all, I am not omnipotent, I am familiar with all aspects, and in this small place, I made a mistake.

Before World War II, many tanks were small barrels, but in the middle of World War II, all tanks were armed with cannons.

Some are short and thick, such as the KV-2, which uses a 152mm howitzer, which is definitely an alien.

Many German tanks are long. For example, the current 75mm tank gun.

The lengthened design has advantages. For example, the trajectory is straight and the precision is quite high. The price paid is the cost.

Tank guns are high-pressure guns with high chamber pressure and short lifespan. At the same time, they must be absolutely strong. Only the strongest steel can be used to make tank guns.

It is difficult to lengthen the tank gun, and it is difficult to process.

And now, the output of the German Panther tank is stuck on the barrel. Krupp is working overtime and cannot meet the demand. Some companies have produced the chassis, but the barrel is short of the barrel and cannot leave the factory.

Therefore, when the 88mm tank gun is successfully studied, it may as well use the 88mm tank gun! This is the suggestion of Kneeberkamp.

In the past, the original tank was used, but in the future, it was changed to 88 mm.

The length of the tank barrel is expressed in multiples of diameter, and the number of multiples of diameter represents how many times the length is the diameter.

First, the 75mm long-barreled tank gun had a diameter of 70 times, while the current 88mm tank gun has only 56 times the diameter. In later generations, it can be seen that 55 times the diameter of a tank gun is already the limit, almost no longer than this, usually more than 40 times.

Knebkamp said while looking at Cyric, hoping to get a positive answer from Cyric's eyes.

Sure enough, Cyric nodded: "This proposal is necessary, and detailed comparison and demonstration are required. If the plan is feasible, I personally have no opinion."

Germany likes to engage in long and double diameters. Later, the Tiger King added the 88mm gun to 71 times the diameter. Now, the engineers under his staff can consider from the perspective of cost and output, which has made Cyrenk very satisfied.

He thought for a while and continued: "At the same time, the next generation of pre-research can also be conducted, such as a 100 mm caliber tank gun."

If we follow the old path in history, in the later stage, when the Tiger tank guns are not enough, it is time to increase the diameter. It is better to start from now on pre-researching tank guns with larger calibers.

The caliber of a tank gun is not as big as possible. After all, unlike a warship, there is enough space to install an automatic loader. If the caliber is too large, such as more than 120 mm, it is definitely an individual task for the loader.

At the same time, the larger the caliber, the fewer shells contained in the tank, which is detrimental to continued combat.

"Yes." Kneberkamp replied. He admired this head of state. Although he always had the right line, he could also listen to the opinions of other people. This is commendable.

After deciding on the chassis and the tank gun, Cyrek did not have time to go to Krupp for a round trip. An emergency message forced him to return to Berlin.

"Our intelligence system has already obtained accurate information. Within two or three days, the British navy is about to make a long voyage." Returning to the capital of Berlin, Reinhardt said to Cyric.

It is impossible for the navy to operate overnight, and it must be prepared in advance.

For example, all kinds of food, canned food, flour, fresh water, etc., need to be transported to the dock, loaded on the ship, and fuel must be loaded, while the officers and soldiers of the navy must leave their loved ones from the land and raise the alert level. , Ready to set off at any time These are all clues.

Therefore, even if the intelligence of senior personnel is not obtained, just by relying on these clues, the activities of the British navy can be inferred.

And now, the battle in Poland has just ended. Originally, Cyric planned to fix it for a few months and then accumulate some strength before launching the scheduled attack, but now, there is no time.

What attack? Of course it was an attack against the British Navy!

In World War II, both the German air force and army showed their strength. In contrast, the German navy basically had no achievements. Especially when Bismarck was sunk, Germany was left with only submarines. After the wolf pack tactics failed, there was no other choice but to wait for death.

And now, since Cyric has passed through and has become the head of Germany, there are of course many differences in this Second World War.

For example, now Cyric needs to destroy the British fleet immediately after the war!

This plan is top secret, code-named Peace Bay, and the real goal is to raid the largest Plymouth naval base in Britain!

This plan was inspired by the later Pearl Harbor project. Britain was an old naval power. In World War II, it was precisely because of the presence of the Royal Fleet that the German navy had to shrink.

As soon as Bismarck came out for a cruise, the British were sunk and completely dispelled Hitler's trust in the navy, so the navy was left with only submarines.

And now, it is about to beat the British navy down!

Now, the people present are all the most senior generals in Germany. When they got the plan for the peaceful bay, they still couldn't help but their eyelids jumped wildly, especially Brausic, who said in an almost trembling voice: "Could it be that , Shall we declare war on Britain in advance?"
