Chapter 374： Compromise to cost (1/2)

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.”
