The Rise of the Empire

First of all, weapons are one aspect. Most of the German ships that use 6-inch guns or even 105MM artillery will naturally not spend much money on armaments. The most expensive servo is saved.

The other aspect is the armor. To be honest, except for a few light cruisers, the thin leather belt armor of other light cruisers is almost pierced by the 6-inch guns. Don't look at the British 6-inch guns. That's right, you read that right, there is no special armor-piercing bullet, and the strongest is the semi-armour-piercing bullet. Because most of the time it is not needed, everyone can just cover their faces with high-explosive bombs! Of course, it is also necessary to prevent the situation in case the British are equipped with 6-inch armor-piercing bullets....

Therefore, if you want to form an advantage over British light cruisers, you must first be able to defend against the British 6-inch guns and semi-armor-piercing shells. The prince is not clear about how many inches of penetration this shell can have. But this does not prevent the prince from making a rough estimate, and the standard of this estimate actually comes from the design ideas during the inter-war period, and this time, the prince refers to the Japanese defense design.

Historically, when the Japanese Navy designed the Mogami cruiser, the protection standard for the side string was set in this way. Part of the power compartment defended against 155MM artillery and underwater projectile attacks, while part of the ammunition compartment protected against 8-inch artillery. The highest power cabin defense standard is gradually reduced from 100MM to 65MM, and the inclination angle is 20 degrees. Considering that the artillery of Mogami is the 155MML60 main gun known for its high penetration. It can shoot nearly 56KG shells at a muzzle velocity of 920 meters, while the 6-inch L45 gun of the British light cruiser in World War I can only shoot a 45KG semi-armor-piercing shell with a similar initial velocity, and the British do not have armor-piercing shells, so the penetration ability must be poor A lot, although the shorter combat distance can make up for it, but the prince thinks that the 70MM armor inclined at 20 degrees can completely defend against 6-inch shells.

As for defense against water bombs? Don’t think about this. On the one hand, it’s because the combat distance of the 6-inch guns in the first battle will not be very far. After all, this is the limitation of fire control and artillery. You must know that the 155MML60 artillery of the Japanese Navy in the second war was at a distance of 20 kilometers. There is still a 278-meter salvo walk, which is simply unimaginable in World War I, and it is difficult to shoot water bombs in medium and close range combat. On the other hand, the defense cost of underwater bombs is simply too high, and the weight is unacceptable, so just don’t even think about it. In fact, if a warship with a weight of 5,000 to 6,000 tons is hit by bullets or mines underwater, it will The element of luck to be able to go back is greater than the element of design.

The side string defense is the standard, and the main horizontal defense can refer to the defense of light cruisers in history. 35MM to 40MM is enough, and the 6-inch gun can block it. In order to save weight, the lower edge of the side string armor will be relatively small, and the entire armor will be gradually reduced from 70MM on the waterline to 45MM. Covers the entire power bay and ammunition depot.

Then there is the layout and protection of the artillery. Generally speaking, the German 150MM can only be said to be sufficient. After all, although the German 150MM artillery has armor-piercing shells, can it penetrate 75MM at a combat distance of 5 kilometers or more? Sidestring armor is also questionable. After all, it is not necessarily right. Shooting angles should be taken into account.

In order to ensure the power, the safest way is naturally to expand the caliber. In fact, the British also began to equip their cruisers with 7.5-inch guns, that is, 190MM guns, after the end of World War I. However, the full weight of this artillery is already very large. The requirements for the 5,000 to 6,000-ton standard platoon required by the prince are a bit high, so the prince is more inclined to take out the 170MM artillery in German history,

The 68KG bomb weight can still be loaded by manpower, and the weight of the weapon system is relatively acceptable.

As for the number of artillery pieces? Don’t think about adding 8 guns. The weight is definitely beyond the standard. Let’s just use 6 guns. Just three dual-mounted turrets can handle it. Anyway, most cruisers in World War 1 fought at a tearing distance, and long-range shooting accuracy was not required. The protection of the artillery must also be improved. The thickness of the front gun mantlet is 100MM, and the side 60MM and the rear 30MM are basically enough. The dressing room at the lower part of the artillery must also have a 60MM level of defense to prevent the dressing room from being exploded after being hit. The ammunition delivery channel in the middle is partly defended. It stands to reason that the probability of this pipe being hit is not high, so just ensure that even if it is hit, the flames and shrapnel will not fall into the lower ammunition depot. It's bad luck if you get hit.

In addition to the opponent's light cruiser, the cruiser itself has to deal with various torpedo boats, so 88MM or 105MM secondary guns are still needed. According to the tonnage, if the remaining redundancy of the tonnage is relatively large, the 105MM gun is used, and if the redundancy is small On the 88MM gun. In theory, light cruisers do not carry torpedoes. On the one hand, they are afraid of being killed. On the other hand, Germany is not yet extravagant enough to use cruisers to strike by lightning.

The power system is prepared to continue to maintain 31,000 horsepower, because relatively speaking, the speed of British light cruisers in history is not very fast, generally around 25.5 knots, while German light cruisers are generally around 27.5 knots. And thanks to the small water tube boilers, some German light cruisers have powerful overclocking power, such as the Karlsruhe 2 light cruiser. This battleship is said to have a maximum power of 55,700 horsepower! In deep water, the speed can reach 29 knots! In fact, this speed is already too extravagant.

Therefore, the speed of the light cruiser can also be appropriately reduced. For example, if it is reduced to about 26.5 knots, the tonnage is controlled to 5,800 tons, and the heavy load is 7,000 tons, then the actual output power can be reduced to about 35,000. If the ship type is further optimized, the power demand can be further reduced.

"Isn't the price of such a warship a bit high?" When the prince said, Tirpitz on the side was constantly calculating how much such a warship would cost. The warship needed to be equipped with waterline armor and replaced with a larger caliber. Artillery, and various artillery servos, all of these need money. In the end, the quotation he gave was that the cost of such a warship was between 450,000 and 500,000 pounds. The price is obviously a bit expensive.

"From the current point of view, most of the British light cruisers are third-class cruisers. They don't even have a waterline armor belt, and in order to increase speed, even the original thick dome armor has also been weakened. 150MM heavy guns are enough. Yes, we can use 150MM artillery on the first few warships, and then upgrade after the British Navy improves its defense." Admiral Liole also echoed Tirpitz.

"Actually, the desired effect of using the 170MM heavy artillery is to ensure the penetration of the opponent's cruiser's defense. We can try the 150MM long-barreled artillery. After all, the 45KG shell can achieve rapid fire, while the 68KG shell is a bit heavy." Boll The Admiral will propose a compromise plan.

"Yes, our first batch of four light cruisers use 150MM artillery, but the penetration must be guaranteed." His Royal Highness thought for a while and said.
