"This is a clash of ideas, and we must ensure that our ideas are more advanced than those of the other, and for the time being, both sides have their own advantages, and the British battlecruisers are fast enough to catch up with any capital battleship in the world except the battlecruisers, and firepower is enough to destroy any armored cruiser. The outer armor combined with the dome armor can also withstand the counterattack of the armored cruiser, that is, in a future war, the armored cruiser of the German avant-garde fleet will be absolutely suppressed by the other side! Tirpitz said worriedly.

"In fact, the battle cruiser is not an ideal battleship, it is too targeted, and lacks versatility, it was born just to deal with the opponent's armored cruisers, in the capital ship class of combat, such a battleship survivability is too poor, especially the larger the battle, the worse the situation of the battlecruiser, because the larger the scale, it means the higher the probability of being shot, this battle cruiser in the north is actually using dome armor to ensure the safety of the core cabin, but once it is shot too much, after the loss of reserve buoyancy, even if the core cabin is intact, Will still be sunk. This problem did not exist with fast battleships with good armor protection. Liu Buyun said according to Xu Jie's explanation.

"Then since your country is aware of this defect, why did you choose to build two battle cruisers? The armored cruisers of the Russians are not as fast as the fast battleships ordered by your country in our country, and if it is against the Russians, all the fast battleships will be fine. Tirpitz said unrelentingly.

"Fast battleships were indeed faster than Russian armored cruisers, but not as fast as the Dutch. We are here to keep the fast loading and cruising suppressed. Only then did they order these two battleships. And the lack of 12-inch heavy guns in the opposing fast fleet is another reason why we dare to use battle cruisers boldly. Liu Buyun said.

In fact, in essence, there is not much difference between a fast battleship and a battle cruiser. How to put it, it is equivalent to the difference between the Lion and Lütsov in World War 1, the Lion is armed with a 13.5-inch gun, but only has a 9-inch armor belt. Lyutsov was about the same speed as the Lion, but had only a 12-inch main gun and a 12-inch armor belt thick. Lütsov is equivalent to exchanging firepower for protection, and the lion is just exchanging protection for firepower. And now. Xu Jie exchanged power for protection, and at the same time ensured firepower.

Is there a top-notch existence in speed protection and firepower, in the history of World War 1, I am afraid that only the Hood can barely be called. However, even if the construction of the Hood used nearly twice the investment of the Queen Elizabeth class, and the full load displacement reached nearly 40,000 tons, the Hood was still no match for Tennessee or Bavaria, let alone the seven battleships equipped with 16-inch guns in the back. And this one-sided pursuit of tall and complete design. Xu Jie will never use it!

Since under various restrictions. A warship of a certain tonnage can only take into account two of the three elements of speed, firepower and defense at most, so how to choose is very important. Did British battlecruisers work? The answer is yes! You don't see, in the Battle of the Falkland Islands, Britain's earliest generation of battle cruisers Invincible and Indomitable directly caused the famous Spey fleet to sink in the sand. After actual combat testing, the battle cruiser with high-speed heavy artillery and light protection is simply a torture for an armored cruiser. It is definitely the best choice to maintain the line of communication and fight all kinds of broken warships! Fisher was right then, the battlecruiser was absolutely perfect against the cruiser!

It's perfect against a cruiser, but what if you run into a battleship of the same class? The Battle of Jutland fully illustrates what it means to beat eggs with a hammer! Betty rushed ahead with 6 BCs. The 5 battle cruisers with Hipper's classmates had a passionate fight, and the number was superior. The British fleet, which had superior artillery, was blown up by 2 BCs in a short time of engagement, and if it weren't for a seriously wounded British officer filling the ammunition depot with water and falling down the fire door, Betty's classmates might not have seen the sun tomorrow! The German Battle Patrol became famous! Later, when Hipper received Scheer's death charge, he fought a bloody way for the follow-up warships of the High Seas Fleet under the fire of the British Grand Fleet, and also took a battle cruiser along the way, which brought the performance of the German battle patrol into full play! The unsinkable Sedlitz became a kind of symbol! Since then, the heavily protected German battleships have become immortal works of the First World War in later military forums!

But, in fact, was it true that the difference in the performance of the battle cruisers between Britain and Germany, as was shown in the war, reached such a point? Is defense really more important than firepower and speed? Let's peel aside the clouds of history and take a closer look. First of all, we need to explain that most of the British battleships in the Battle of Jutland were lost due to the detonation of ammunition, and the reason for the detonation of ammunition was that the British had only one fire door in the ammunition hoisting shaft, and this fire door was generally still open! In order to increase the rate of fire, the British Royal Navy soldiers who were beaten with chicken blood did not close the fire doors as required! Originally, the turret and turret were penetrated the most, igniting the shells and propellants in the turret, and the most important thing was that the turret was destroyed, but if the flames of the explosion followed the ammunition hoisting shaft into the ammunition depot, it would be a different matter!

Precisely for design and operational reasons, the British paid for 3 battlecruisers for this! What most people don't know is that in the Battle of Dogle Sandbank, Hipper's flagship Seydlitz also scrapped 2 turrets at once for this reason! And there was also a brave soldier who saved the entire warship by filling the ammunition depot with water. Immediately after the end of the war, the Germans adopted double fire doors and stricter operating procedures, thus preventing the occurrence of martyrdom. Of course, if you can send shells directly into the ammunition depot, then no matter how strict the measures are, you will inevitably set off firecrackers! And after the British learned the lessons of Jutland, such things as lighting firecrackers will not be so frequent, well, Hood was directly stabbed through the ammunition depot, which is something that God can't do.

Another tragedy of the British was the shells, and were the German battle cruisers really indestructible? The answer, of course, is no, compared with German battleships, German battle patrol protection is generally 2 levels worse! WITH THE EXCEPTION OF THE DE FLINGER CLASS, THE SO-CALLED 300MM ARMOR OF THE OTHER GERMAN WAR CRUISERS WAS JUST ONE ON THE WATERLINE, AND THE ARMOR USED TO RESIST SHELLS WAS 9-INCH ARMOR. SADLY, THE BRITISH HAD 13.5-INCH GUNS IN THE SKY OVER THEIR BATTLE CRUISERS, AND EVEN THE 230MM OUTER ARMOR AND DOME ARMOR COULD NOT PENETRATE IT! And this tragedy is caused by the instability of picric acid explosives, as well as the tragedy of the fuse and the soft quilt cap! Where a shell can be tragic, it's all tragic! It's no wonder that the penetration is so poor.

Let's look at the shells of other powers of the same period, not to mention the hardened cap-piercing shells of the Germans against the sky in World War 1. Even the 1916 armor-piercing bullets of the US imperialism have a good penetration depth. The Americans' 14-inch 45L gun can penetrate 13.3-inch hardened armor at a distance of 14,000 yards, while the 14-inch 50L cannon can penetrate the same thickness of armor to increase the distance to 16,000 yards! In other words, if the armor-piercing shells of the British were only at the level of the Americans, the 13.5-inch heavy guns on Betty's battlecruisers could easily blow up the armor of all German battlecruisers except for Dufflinger and Lütsov, and if they were closer, it was very possible to smash Lütsov!

That is, although the German battle cruisers of the same period were indeed better than the British, the difference between the two sides was not really large if it were not for the illegal operation and the overly tragic shells. In terms of combat effectiveness, the combat effectiveness of the Lion with qualified shells and arson is higher than that of the Seydlitz and Moltke class, and lower than that of the Dvlinger class. In other words, although the British took a detour because of the trade-off, it was not wrong to emphasize the firepower itself.

It is necessary for the battleship to have good protection, which has been verified in the extremely brutal contest in the Battle of Jutland, and it is also necessary to have good firepower, which has also been verified in the Battle of Jutland, although the caliber of the guns of the German battlecruisers is a little smaller, but with excellent armor-piercing shells, the firepower of the German battlecruisers is actually stronger than that of the British battlecruisers. THIS IS LIKE THE FRENCH 330MM MAIN GUN IN WAR 2, ITS ACTUAL ARMOR-PIERCING ABILITY EXCEEDS ALL THE 14-INCH NAVAL GUNS IN SERVICE IN THE WORLD, AND THE POWER IS CLOSE TO THAT OF A 15-INCH NAVAL GUN! Of course, the so-called proximity also means that Bismarck's 15-inch naval gun is incomparable with France's own M1935 15-inch naval gun, as well as Italy's 15-inch naval gun of Andorsha.

"In the eyes of the Huaxia Fleet, as a fleet trapped in a semi-enclosed sea area by the enemy's powerful fleet, what you need is firepower and protection, not speed and range, and Germany has only one goal, that is, to defeat the British Grand Fleet! The range is obviously useless, what about the speed? It is basically impossible for a battleship to escape from the opponent's guns simply by virtue of the small speed difference, and no matter how good the protection is, the bow and tail of the battleship are still fragile, and in the face of dense bullet rain, it is impossible for the hull not to enter the water, and the water or other damage will definitely lead to a decrease in speed! Simply escaping does not give you a higher probability of survival, because it is a formation battle, and the formation must take care of each battleship, so the speed of the fleet depends on the slowest rather than the fastest. Liu Buyun paused and said.

"Isn't speed the most important factor in choosing the conditions of engagement? Once you have a speed advantage, isn't it possible to adjust your tactical deployment in time to gain a local advantage? Isn't the greater the tactical advantage gained by the larger the speed of the fleet's engagement? "I have to say that what Liu Buyun said today has subverted the perception of ordinary people, is speed really the least important of the three factors? Tirpitz said with some doubts.
