The Rise of the Empire

If only coal-fired boilers and steam engines are used, 23 knots is the limit for large cruisers, and 20 knots for battleships. No way, the weight and volume of coal-fired boilers and steam engines are too large and the efficiency is too low. If you want to achieve a higher speed, you must upgrade the boiler or the main engine. Both can be upgraded together or separately. The early dreadnoughts can continue to use coal-fired boilers and steam engines. But the early battlecruisers had to improve their boilers and steam turbines.

  As far as Ruprecht is concerned, it is not difficult for a cruiser to have battleship-level firepower, but the difficulty is that it has a speed that exceeds that of a conventional battleship. The Japanese like to call the pommel horse the world's first battle cruiser, based on the fact that the pommel horse is equipped with 12-inch heavy artillery and has a speed of 20 knots.

But if you follow this standard, the Italian Queen Margarita was the earliest battle cruiser. It was in service in 1904. It has 4 12-inch guns, 4 8-inch guns and a speed of more than 20 knots. When the Queen Margaret was in service, the Pommel Horse had just started work! What is the difference between the two parties? Why is it called BB in Italy and ACR or BC in Japan? This unscientific.

Of course, some people say that the two warships have the same speed as the cruiser at the same time. The passer can only say that this sentence was correct when the Queen Margaret was in service, but after the service of the Kurama, this The speed is slightly worse than that of the large cruisers of the time. The Kurama entered service in 1907, but had a speed of 20.5 knots, while the speed of British first-class armored cruisers during the same period was generally 23 knots! The speed difference is 2.5 knots. Of course, you can also take a slow boat like Rurik 2.

With some private goods, Ruprecht believes that a real battle cruiser must have at least the same speed as the large cruisers of the same period, and have at least a speed advantage of more than 3 knots against the battleships of the same period. Only in this way can the battlefield be fully utilized. The role of cruisers. In other words, in the current situation where slow battleships generally have a speed of around 18 knots, the real battle cruiser should be around 21 knots. Most of the first-class cruisers in the same period were not at this speed

What is the purpose of   Battle Tour? Fisher's definition is faster than battleships, more capable than cruisers, and can use battle cruisers to suppress opposing cruisers. It was originally not intended to be used in battle line decisive battles. The German definition is that at least he must be able to beat the British battle tour of the same period. What about the definition of Prince Ruprecht?

The definition of    is more complicated. Part of it is because it is really troublesome, and the other part is that His Royal Highness has not yet figured out how to say it!

  Simply put, it means that the firepower is enough to pose a serious threat to battleships of the same level. The speed is faster than battleships. The specific criterion is that if the luck is not very bad, the superior opponent can get rid of the opponent's range before he takes a heavy blow.

This sentence looks very simple, but the amount of information it contains is still very large. First of all, the first sentence is that firepower can threaten battleships of the same level. This requires that the artillery caliber of battle cruisers is large enough, at least in German history. Battle patrol is not good. It is still possible to knock on a lion with imperfect fire prevention with chocolate, but you and an American iron tortoise try? I can't beat you!

The firepower of a battlecruiser can be slightly inferior to that of a battleship, but it must not be too far behind. For example, the opponent has 10 14-inch guns, while the BC has only 8 14-inch guns. This is acceptable, but 6 is not enough. If you have 8 12-inch guns, it will pass directly, and the designer can pull out and shoot!

  And the second sentence is more complicated. The latter can run out before the battleship hits the battlecruiser. Battlecruisers of the same level will certainly not be able to beat battleships. This can be tolerated, after all, the tonnage is limited. Strengthening on the one hand will weaken the other, but at least the defense must not be instantaneously killed, nor can it be easily slowed down. Of course, if you run into such a thing as a water bomb directly piercing the ammunition depot, there is no way, it is God that made you die, no wonder someone else.

  So, in order to achieve this goal, there must be strong protection and a certain speed. The protection must be to ensure that the core area can avoid being shot by the guns of the battleships of the same level, and the non-core area has a certain amount of damage redundancy. Before this redundancy reaches its limit, the battle cruiser can rely on speed to get out of the effective range of the battleship.

The idea of ​​trying to escape from the enemy by relying solely on speed is sometimes not reliable. There are many examples of this. For example, the battlecruiser Invincible in the Battle of Jutland, this buddy is backed by the British fleet. The backstage was terribly hard, and as a result, because you rushed too far forward, you were shot in seconds. The Germans did not give you a chance to escape! Is there a speed without protection and a hairy use?

And in the Battle of Jutland, facing the huge German high seas fleet, Thomas’s four Queen Elizabeth-class battleships performed much better. Their speed was indeed not as fast as the battle cruiser, and even the rudder was damaged. What is the result of the inoperable situation? The queens braved the bullet rain of German BB and BC to turn in successfully, not only escaped their birth, but also cleaned up the German fleet.

   Therefore, excessive pursuit of speed is actually not desirable. In the opinion of the Prince of Rupley System ~www.readwn.com~, it is possible to build several BC ships with speeds above knots for reconnaissance as avant-garde. But it must not be the core of the fleet. Because in the case of a certain tonnage, this kind of warship will always have various shortcomings. The British lions and tigers are not good for defense, and the German chocolate is not good for firepower.

  The result of insufficient defense of the former is to be fired. The latter is at a loss for battleships. The real idea is still the British Queen Elizabeth-class battleship, which has a moderate speed and good protection. If the quality of the shells is not considered, the firepower level is the highest. Can escape from the hands of a large number of BB, can beat the high speed BC. More importantly, if you change it, you can use 2 battles...

  So in the future fleet plan of His Royal Highness, the number of pure blood BC and pure blood BB will not be much, the former will be a separate reconnaissance force. The latter is a substitute when the power technology is not complete. The largest number should be a fast battleship similar to Queen Elizabeth with a speed of about 25 knots.

  Of course, this is only a plan for the future. What Prince has to do is to promote the use of kerosene mixed-burning boilers and the development of steam turbines. The former is not difficult. The latter can only be used on smaller ships such as torpedo boats and destroyers.
