As soon as Willisa wanted to join the discussion about the problems that arose during the test, she was immediately snatched by the more interested Yuka-

"In fact, in the upgrading of combat vehicles in World War II, every country has the habit of improving the power of tank guns, like Germany, which likes to increase the double diameter of the barrel, and the 75mm short-barreled gun of the No. IV tank continues to increase the double diameter, until the 75mm L/70 gun of the Black Panther, and even the 75mmL/100 gun of the E series, and the 88mmL/56 gun of the Tiger tank towards Ferdinand, Cheetah, and King Tiger The 88mmL/71 gun is a good example; The Soviet Union likes to increase the caliber, and the 100mm, 122mm, and even 152mm guns are used in this is the best manifestation of this, while we in the United Kingdom like to increase the bore pressure so that the shells can be fired at a more powerful speed. ”

"Ah...... So, what do you want to express by listing these contrasts? Jackfruit wondered.

"What can I do to increase the pressure of the chamber? You know, when the Crusader tank was equipped with a 40mm QF2-pounder gun, the interior space was very spacious, but when it was equipped with a 57mm QF6-pounder gun with a caliber that did not increase much, the internal space was suddenly narrowed by more than half, why? Because of the increase in the size of the backseat of the artillery. Originally, the Cromwell tank was planned to be equipped with a QF17-pounder gun, but as a result, not to mention the squeeze of the crew in the interior space, it couldn't even fit in, and in the end it had to redesign the hull and turret, wasn't it? ”

"So what?"

"Still don't understand?" "Even if it looks a little small from the outside, if you count the whole artillery, it's actually even heavier than the 3.7-inch howitzer, which is nearly twice the caliber of the gun." ”

This is a historical fact, the Cromwell tank forcibly expanded to carry the QF17-pounder gun, which was a failed model, and then simply mounted the QF17-pounder gun on the Sherman tank, which was tall enough and large enough, and the product of the Anglo-American hybrid was a generation of famous Tan-Firefly tanks that had the opportunity to slaughter tigers and leopards.

"I see, chamomile is so knowledgeable. Are you hurt? What is the condition of the vehicle? Rose Hip said.

"Jackfruit, it's okay."

"Chamomile, it's okay."

"Candied fruit, it's okay."

"Mint dew, it's fine. The tank is working normally, and we can continue to participate in the tests. ”

"Okay, continue to finish the rest of the way, and then go to the shooting range." Rose Hip ordered.

……………………………………………………

Ten minutes later, the range—

This range is not very large, the firing distance is only 500m at most, and the target is generally at sea when practicing shelling above 500m or even 1000m or 2000m.

However, for the cruiser tank corps led by Roseguo, there is no need to be good at long-range shelling, the cruiser tank relies on mobility, and only needs to shoot within 300m and hit more than 40% of the moving fire within 100m, which is enough, and more than 50%, it is the ace gunner.

Willisa drove the chariot and followed the Cromwell tank to the designated place of shooting.

"Turn 55° to the right and reload the armor-piercing projectile." After looking at the target designated by the rose hip, Mint Dew ordered.

"Hehe, it's finally the point." Yuhanari suppressed the small excitement in her heart for the first time to use such a large-caliber howitzer, and began to rotate the turret.

"Uh......h It's a little heavy, but I'm obviously quite confident in my strength. "Jackfruit looked a little struggling to lift the thick 95mm shell and load it into the chamber.

"Shoot!" Rosehip gave orders to her chariot.

"Boom!" A burst of fire flashed in front of Cromwell's QF6-pounder gun, shattering a target 300m away in an instant.

Rose Hip poked her head out, picked up the binoculars and looked at it: "The feeling of firing a cannon is similar to that of a Crusader tank, mint dew, shooting." ”

"Understood." Mint Dew nodded and said to the car, "Chamomile, shoot." ”

After aiming for a while, Yuhani deducted the blaster, and a shell with a significantly lower initial velocity, but extremely thick compared to the tank gun next door, flew towards the opposite target with a more intense fire and sound.

The moment the armor-piercing bullet touches the target, the hot metal stream is like a laser, penetrating the target, if the object is a chariot, the result is the same, the metal jet will further ignite everything in the car, but the target base is not solid, the huge mass of the cannonball itself, so that the target fell down, but the fact of penetration also came into everyone's eyes.

"Is it a successful penetration, it is just a target that can be pierced by the QF6-pounder gun, and the effect of the howitzer is almost the same." Rose Hip was a little surprised.

In common sense, howitzers are less effective than anti-tank guns. The current situation is, naturally, the credit of the howitzer brushing the large caliber.

"Well, well, I have to propose it to Lord Darjeeling, maybe under the rules of the battle lane, it will be more powerful for our cruiser tanks to be equipped with large-caliber howitzers. Small-caliber anti-tank guns, on the contrary, are heavier, which affects the mobility...... And the additional armor will also affect the agility of the vehicle, so this should be removed as well, right? Rose Hip said.

"That's amazing, chamomile, thank you for the explanation." Willisa looked back and smiled at Yuhanari.

"Where, where, I just like chariots, hahaha." Yuhanari scratched her head shyly.

Erisha is very grateful to Yuhanari for helping her guide her through a lot of things.

Originally, one of Willissa's goals was to influence as much as possible, trying to distort St. Gloriana's improvement of the vehicle technology tree.

If you look at the tank data, the conclusion drawn by Rose Hip is basically correct, but-

In actual combat, the opponent is not a quiet target, the combat vehicle must not stop making various actions and the opponent in actual combat, it is impossible to shoot the target quickly, the first few guns are generally fired in school, and the small-caliber gun is loaded quickly, which is conducive to rapid shooting; The loading of large-caliber howitzers is relatively difficult, because of the large volume and small ammunition load, the point is that the trajectory of the armor-piercing projectile is not as straight as the armor-piercing projectile, which also increases the difficulty of calibrating the fire, that is, the grenade has some advantages, but there are not many vehicles that can be destroyed by this level of grenade alone in the battle lane competition.

Don't you see that in the previous duel between the truth and the continuation, even a 100mm grenade could not break a T-28M? The T-28M is a third-class vehicle, that is, second- and third-rate schools are equipped with such a low-level combat vehicle as one of the main forces of the resistance line.

Large-caliber grenades can also play a big advantage in the chariot competition, where almost all of them use crispy chariots.

At the same time, Rose Hip feels that the armor affects the problem of mobility, of course, there are gains and losses, the thickness of the armor and the speed of the combat vehicle have always been inversely proportional, but the mechanical power is higher than a certain level, it is useless, driving such a fast chariot, is there still a chance to aim and shoot? Even if you shoot while on the move, you have to stop and aim; Even if you shoot on the move, you must have a great ability to grasp the shooting window or try to make yourself and the target relatively stationary. Not everyone is as hung up as the Finnish Quercoo.
