Chapter 910 Japanese Demon Sword 2

"First of all, everyone knows that with the emergence of dreadnoughts, the defense pressure of battleships is very high. We need to ensure that the armor belt is high enough and thick enough, and at the same time, the deck must be strengthened to ensure that it can withstand the impact of horizontal bombs. In fact, 2-inch horizontal armor cannot directly face super-dreadnought-level artillery shells. As for this defense problem, most British warships have not solved it well. Regarding the recent tragedy of the Grand Fleet, as the chief designer of the Navy, I I am deeply sorry, but everyone should understand the underlying reasons." Incott put on an expression that said this is not my fault and you all understand...

To put it bluntly, isn't it because the funds for returning the army are limited, and everyone emphasizes the size of the fleet so much that the money without ships is not spent enough... Everyone here does understand!

"This is the cross-sectional view of the Scharnhorst-class battleship that the Japanese shared with us. I have to say that the Germans' defense of the core cabin is simply perfect!" As he spoke, an assistant flicked a slide on the curtain. superior.

"The thickness of the German armor belt is actually not very high. The thickness of the sides of their Scharnhorst battleship is 0.5, but because it is tilted at a certain angle, it has gained great anti-strike capability. According to the Japanese According to the data and our experiments, if the 11-inch armor plate is tilted 15 degrees, then the current 15-inch artillery of the Empire is simply impossible to penetrate at a distance of 9 kilometers. In theory, the Queen's 15-inch cannon is simply It was impossible to penetrate Scharnhorst's vertical armor belt."

"Looking at the underwater extension of the armor belt, at this position, Scharnhorst's armor belt changed an angle, and the lower edge to the bottom of the ship is not hardened armor, but ordinary homogeneous armor steel with a thickness of 4 Between 3 inches and 3 inches. This is to prevent underwater bomb attacks, and the last layer of steel plate is also of great benefit in protecting against underwater explosions."

"Another difference from our battleships is that the new German battleships do not have dome armor. They use the weight of the dome armor for horizontal armor, so the thickness of the horizontal armor part of the German battleships is more than 3 inches! And the Japanese Fuso Class battleships also adopt a similar layout. The main armor belt, which is inclined at 18 degrees, is 4 meters high including the extension below the waterline. The horizontal armor is 3 inches, and the upper part of the ammunition magazine is 4 inches. Underwater mine protection Walls range from 3.2 inches to 50mm.”

"How should I put it? Let's not talk about whether this defense can block the German attack. Anyway, at least our artillery shells are impossible to penetrate. I guess it will be very difficult for the Germans to penetrate Fuso's defense, right?" Ying Court said.

"But if this is the case, the overall armored belt is probably very heavy. And if I remember correctly, the captain of the Fuso is very large, and the five 15-inch twin turrets take up a lot of space." Jericho said . (You read that right, the firepower of the Fuso battleship in this plane is 10 15-inch L42 cannons!)

"That's right. This aspect of work has the originality of the Japanese. They have made a series of optimizations to the armor layout. First of all, their artillery arrangement is like this,

Three turrets are placed on the front deck. Among them, the No. 1 and 2 main turrets are simply captured. The No. 3 turret is opposite to the No. 2 turret, and the gun is backward. In this way, the centralized arrangement of the ammunition depot can be achieved, while the other The two turrets at the rear are in a simple backpack arrangement. Between the No. 3 turret and the bridge is the main motor compartment of the battleship. The Japanese arrangement saves space very well. "

"In addition to making the weapon system as compact as possible, the Japanese also made some articles on the power cabin. They used a German-style small water tube boiler, and because there is no dome armor, the height of the boiler can be higher, and the total power volume is certain In this case, if the height is higher, the occupied area will naturally be smaller. They adopt a three-layer boiler warehouse layout, which not only effectively saves length, but also enhances redundancy against underwater explosions. By the way, , they purchased small water tube boilers produced by Germans, of course through private channels, which saved a lot of weight."

"But even so, the length of the Fuso-class battleship's main armor belt has reached 60% of the total length. This length is destined to use a lot of tonnage, and the Japanese approach is to reduce the thickness and height of the front and rear armor belts, and The defense of the gun gallery has been reduced to save a lot of weight to meet the defense of the core compartment and weapons."

"As for the underwater defense system, the Japanese followed the Germans' subdivided compartment design, which was not difficult. Asama and Rurik 2 began to design this way, and when it came to the Scharnhorst-class battleships, the Germans adopted The design idea is a multi-layered compound defense structure of empty warehouses and liquid tanks. The Japanese have a three-layer warehouse, with an outer warehouse, a liquid tank in the middle, and a coal bunker inside. The depth is about 3.8 meters to 4.3 meters, and the last one is It’s a mine protection wall, plus subdivided compartments. Although I don’t know how it compares to the underwater protection of German warships, it is at least certainly stronger than all our warships.”

Well, although he was telling the truth, Incott's words really hit almost everyone present.

"Okay, let's take a final look at the overall picture of this class of battleship. This is a behemoth with a length of 210 meters and a maximum width of 32 meters. It is equipped with five twin 15-inch L42 turrets. The side armor belt is The tilt is 18 degrees. The horizontal armor is 3 inches to 4 inches, and the front and rear armor belts are 3 inches to 4 inches. There are domes to protect the transmission shaft and steering gear room. A total of 18 small water tube boilers, 4 steam engines, 4 Shaft propulsion, the maximum rated output power is 80,000 horsepower, the maximum speed can reach more than 25 knots, and the standard displacement is about 31,000 tons!" Finally, Incott outlined the general situation of the warship in a few sentences. But even so, everyone can see how powerful this demonic sword hidden in Japan's snow is!

(First of all, regarding the issue of speed, don’t compare it with the Queen, because the Queen’s hull design may be poor. With nearly 80,000 horsepower, it can only run less than 25 knots. This is a failure, and like Nagato, 34,000 tons Under such circumstances, it ran 26.7 knots with an output of 99,500 horsepower! Therefore, it is completely acceptable for the Fuso in this plane to run more than 25 knots.)

"What a pity. This class of battleships actually belongs to Japan, not ours. When I first joined the navy, I believed that the battleships of the Royal Navy were the best." Jericho couldn't help but sigh.

"Then when did you realize that this was a wrong idea?" Jerram asked.

"During the Battle of the Philippines, when I saw the Asama-class battleship." Jericho replied.
