Chapter 388: Black History 1
"Equipped with 10 280mmL50 guns, the thickest part of the main armor belt is 270mm, the front of the turret is 9 inches, the sides are 170mm, and the thickness of the gun mount is up to 230mm. The www.biquge.info is equipped with 24 boilers and 4 steam turbines, with a rated output of 54,000 horsepower and a speed of 25.5 knots. With a displacement of 22,000 tons, am I right? Mr. Wigner? When Wegner had finished introducing his ship, the prince repeated the data.
"It's like that, Your Highness the Prince." Wegener nodded.
"Well, I want to ask, what is the approximate height of your so-called 270mm main armor belt? The description of the main armor belt is 270mm to 200mm thick, so well, I wonder what is the proportion of steel plates of these two thicknesses! The prince raised the first question!
"This is just a rough architecture, we didn't finish all the design work, we just came up with a rough plan for our own plan." Wigner's face changed slightly.
The design and drawing of a battleship is a very cumbersome thing, and before the winning bid is confirmed, most of the design is just a frame, such as how large caliber the gun, how much speed, how thick the armor, but more specifically, for example, how high the steel plates of various thicknesses in the main armor belt are.
Historically, the basic framework of the Moltke-class battleships came out in May 1907, for example, the total tonnage was about 22,000 tons, the armament was 10 11-inch guns, the speed should be more than 24 knots, and the defense should be somewhat higher than that of the von der Tann, etc., but in fact, the real design work was only completed in March 1908.
That is to say, now Wegener really does not know what the height of this armor is, and then calculate it according to the budget and tonnage, if there is a large margin, make it thicker, and if the margin is small, make it thinner. At least at the beginning of the bidding, no one set the height of the various armors.
Therefore, the prince's question caught him a little off guard, after all, there are some things that can't be judged before they are made! The prince asked the question that he could not answer.
"These things need to be actually calculated, and I can't answer you until the design is actually completed." Wigner said softly.
"Okay, guys, now the question is, what should be the height of the so-called 270mm main armor belt here? Is it 1.8 meters, or is it 3.8 meters? If the former is the case, then for this battleship, the most likely to be shot is the 270mm armor with only the width of the belt, or the 200mm armor with a large upper area? ”
"Everyone knows the technology, you should know that generally speaking, the height of the sidechord protection of the battleship, including the underwater part, should be at least about 5 meters! I would be interested to know how much weight could be used for defense with such tonnage to ensure speed and firepower, and what exactly was the distribution of the main armor belt. The prince said.
"This needs to be calculated, and it is impossible to answer it now. Your Royal Highness, please do not ask such unanswerable questions. Liao Le on the side said with some dissatisfaction.
"Hehe, that is, if William Royal Shipyard wins the bid, they can ensure that the main armor with a narrow strip meets the requirements, regardless of the specific height? Is that so? Don't you think it's too irresponsible to do so? The prince paused and continued: "I am not targeting you, Admiral Liaole, nor are I targeting you, Wigner. ”
"I'm targeting all of you!" The prince glanced at Tirpitz, Liole, and Wegener, who were sitting opposite! "Your plan is full of loopholes, you are not putting the needs of the Navy and the lives of the officers and men of the fleet first at all, but thinking about how to fool through with a vague concept!"
"Your Royal Highness, you have to have proof for what you say! The plan submitted by the Bavarian side is indeed very detailed, with more detailed sketches, and there are data posts, and the height, thickness, weight, and depth and width of the underwater defense system are very detailed, which is commendable, but you must not attack others without any basis. Prince Heinrich said.
"No, I have evidence, my design bureau once roughly calculated the weight of the defense and the thickness of the side chord armor of this class of battleships, according to our calculations, if the side chord armor covers 2 and a half decks, (half of the layer is an underwater extension) then the thickness of the 270mm armor will definitely not exceed 2.2 meters! And how high is the 2-story half-deck, I think everyone knows better, at least 6 meters! That is, two-thirds of the battleship's defensive area was protected by only 200mm side-chord armor! What is this not a crime? The prince asked
The flank defense of the Moltke-class battlecruisers in history is not necessarily much stronger than that of the lion and tiger, from the upper deck to the bottom of the main armor belt, there is a total height of about 8.2 meters, of which the top upper armor belt is an armor belt with a thickness of 200mm and a height of 2 meters, the middle is an armor belt with a thickness of 200mm and a height of 3.15 meters, and then the main armor belt of 270mm is below! And this section of armor does not cover the remaining 3 meters of height, in fact, the height of this 270mm armor belt is only 1.8 meters! When it came to the bottom of the water, the thickness of the part was quickly reduced to 130 mm! To make matters worse, the main armor belt is mostly underwater. Only one-third of the water is exposed. That's less than 0.6 meters!
If you calculate the probability of being shot on the side chord, then the height of the water part is less than 6 meters, the main armor is 0.6 meters above the water, and the probability that the main armor belt can withstand the opponent's shells is 10%! In fact, what Moltke Sidechord can really use is the 200mm armor belt!
Well, thank God, thank you, the 1 World War did not have a couple of large-scale engagements, the British also had problems with the shells, and Moltke's problems did not come to ....... You must know that although the shells of the British are scum, the shells fired by the 13.5-inch guns still have a chance to penetrate (blow through) the 8-inch armor!
"This is just your estimate, and what the facts are, it depends on the overall design. I admit that it is true that the plans of our shipyards are not as detailed as yours, but I think that our plans are clearly unreasonable for you to judge. As a designer, although he did not complete all the design, he also knew that it was still difficult for this tonnage to achieve such performance. The planned tonnage of Bavaria's battlecruisers reached about 25 thousand tons. Naturally, there was ample weight to arrange the armor. And the 22,000 tons of the ship of his own plan is indeed a little lower.
"It's interesting, both sides have their own opinions." At this time, the king in the upper position broke the somewhat anxious atmosphere on the field.
