And just as Britain and Japan were getting closer, the German Imperial High Seas Fleet was also preparing for the last class of battleships of the Imperial Navy before the war, and this class of battleships named after the Kingdom of Bavaria would be the pinnacle of the German High Seas Fleet in World War 1. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info He and his brothers spoke of becoming the sharpest sword in the Imperial German Navy! For this reason, both Ruprecht and the technical departments under the Admiralty are doing their best to improve all the details of this battleship!

"Your Highness, this is the final plan proposed by the Bavarian Ship Design Bureau and the Germania shipyard in the port of Kiel. This plan fully considers the performance, risk and cost of the battleship, and at the moment, we could not find a more suitable plan. "Sir Eden, the chief designer of the battleship, sent a document to Ruprecht, while his assistants unfurled line drawings on the wall.

"In order to reduce the technical difficulty, we finally chose four twin 15-inch guns as the main armament of the Bavaria-class battleships, this new C1906 turret can ensure that the gun can reach a theoretical rate of fire of 2.5 rounds per minute, and in actual combat this type of turret can also reach a rate of fire of more than 2 rounds per minute. The new 15-inch L45 gun can fire shells weighing 870 kg at a speed of more than 780 meters per minute. This excellent hardware performance is an advantage even against ships of the same class as the British, and according to our intelligence, the maximum rate of fire of the new twin 15-inch turret of the British is only 1.5 rounds per minute. Their bullet weight and muzzle velocity are close to ours, but the technical gap in shells gives our artillery an advantage. ”

"Our new shells have a longer body and a slender hood in front of the cap, which optimizes the flight performance of the shell and has better velocity. Moreover, the quilt cap is still a hardened quilt cap after cold quenching, which has a better effect on hardened armor. At the same time, our fuses are more stable, and stable TNT explosives are used, which ensures that the shells will not explode until they penetrate the opponent's armor. And that's just the surface properties of this shell. Sir Aiden paused and continued.

"Following the idea you provided, we studied specifically the movement of shells in the water. And according to the data collected in the experiment, corresponding improvements were made. The idea of allowing a shell to continue to run steadily for a distance and then hit a battleship after entering the water is really good, and this kind of underwater shell is somehow more threatening to the battleship than a torpedo! ”

"Look here, this is the whole process after our new shell enters the water, after the shell enters the water at a certain angle, first the hood of the shell will fall off, and then after the correction of the bottom of the special treatment of the projectile, the shell will move forward in a relatively stable course in the process of sinking, and during the period of falling from the water surface to a depth of 6 meters, the shell can run stably at a distance of 80 bullet diameters! That's a distance of almost 30 meters. ”

"All things considered, this shell can completely avoid the underwater armor belt of almost all warships except Germany when it hits the enemy ship, and then penetrate the underwater defense system of the enemy ship at once, if you are lucky, the underwater bullet can even penetrate the mine protection system up to 3 meters deep, and then explode in the core compartment in the back, if there is an ammunition compartment or power compartment behind, just one shell has a chance to hit the opponent hard!"

"Very nice design." Ruprecht nodded with satisfaction and said, at the same time a little proud in his heart, to ask what shells are the most difficult to defend? In the face of vertical armor, even in the period of World War II, the inclined armor that used the theory of taking off the quilt was enough to deal with most opponents, for example, Veneto's 70mm outer plate and 280mm inclined armor were enough to deal with most of the naval guns except for Yamato's 460 heavy guns. Of course, if it's too close, I don't say it.

As for horizontal protection? This is a little difficult to do, after all, the historical American MK6 16-inch L45 naval gun and MK8 1225KG super-heavy ammunition are really scary. Richelieu's 170mm main horizontal armor and 40mm dome armor failed to block the 16-inch guns and shells of the American imperialists, which can be called BT. You must know that the main horizontal defense of Richelieu-class battleships is the second in the world. However, although horizontal defense is a bit more difficult, it is not impossible. There is a saying that the defensive positions of the two are reversed, so that the thinner 40mm armor is thickened a little more, and put it on top to peel off the shell cap, and then the lower layer of 170mm thick armor may be better for hard anti-ballistic bodies, or directly two layers of armor are superimposed together, and the defense effect of 210mm thick armor is definitely better than 170mm+40mm. In this case, it is possible to block the long-range lob of the MK6. (Of course, this distance can't be too far, if you want to say a horizontal shell 35km away, then God can't save you--! ）

But having a bullet in the water is definitely the most difficult to defend, because the range of the bomb in the water is too wide, from below the waterline to the bottom of the ship is the range that the bullet in the water may hit, even if the draft of the capital ship is 9 meters, you can't get enough thick armor at such a large height (in fact, after the shell drops to a certain extent, the trajectory is messed up, so the main range of the shell is still below the waterline. ）。 Imagine that if you calculate it in 6 meters, plus the part of the waterline, the height of this side armor is more than 9 meters! This is obviously unacceptable, after all, the highest battleship in the world with the main armor belt is also only 7 meters, and this is the George V-class battleship built by the British during the 2 war.

Maybe in the case of the 2nd World War, or in the case of a traverser, you can think of an underwater defense system similar to the Yamato and South Dakota-class battleships that stretches obliquely in the countryside of the armored belt, but in other countries in this plane, it is already very conscientious to be able to make a layer of 30mm to 40mm highly elastic steel plate behind the underwater defense system. And this level of underwater defense system is absolutely unable to block the underwater shells of large-caliber artillery. This is the biggest and most effective killer feature of this new 15-inch gun, because almost all warships are defenseless against it.

Look at the history, those battleships that were hit by a medium water bomb, there were almost no good results, and the Lytsov was detonated by a water bomb that detonated the compressed air in the torpedo compartment. The Bismarck was depleted of fuel by an underwater bomb, and the Japanese battleship Tosa was also heavily damaged by a naval target test. Therefore, combined with his own experience, Ruprecht specifically demanded that the stability of the ballistic trajectory in water must be considered when designing the shell. Let the shells run in the book for as long as possible, in fact, the length of 70 to 80 bullets is not particularly good now, and the length of the 110 bullets in the water can be run by the Japanese in the history of ......the Japanese.
