Traditional Navy in the Early 20th Century

Among the warships purchased by China, German-made warships should be the best. I think German-made warships are either made in China or Britain. So, the quality of warships made in Germany is better than that made in Britain? '

It's not good quality, but different design concepts. At that time, the design concept of British naval warships was "speed is protection", that is, they believed that a good warship should have the speed, range and power that the opponent did not have, and have overwhelming firepower. At that time, because the German navy was suppressed by the British navy, the domestic shipbuilding capacity was limited, and it took a long period to replenish a ship. Therefore, German warships pursue protection and survivability in design. And objectively speaking, in the Yellow Sea naval battle, domestic and British warships are cruisers or destroyers, and German warships are battleships. It is normal for Japan to survive without battleships. To sum up, it is not that the quality of German warships is better than that of British warships.

When Japan is vigorously building its navy, why not buy several Dingyuan class and Zhenyuan class battleships like beiyang fleet? '

The reason is simple: Japan has no money. Even if Japan defeated the Qing Dynasty and got reparations, the reparations were not paid in one lump sum. Moreover, in order to prepare for this war, Japan borrowed a huge sum of money from Britain (more than 30 million pounds, equivalent to 65.438+500 million taels of silver), so just repaying the loan almost offset the compensation obtained. In addition, the practical example of the concept of "battleships play a decisive role in naval battles" is the Sino-Japanese War. In other words, battleships that can be easily bought in front of the station may not be bought after the war. Finally, Japan actually bought two monarchies, but the construction period is long and it will take several years to deliver them.

During the Russo-Japanese War, the Russian Black Sea Fleet+Pacific Fleet+Baltic Fleet could also overthrow the Japanese joint fleet, right? '

In theory, the Russian fleet dominated the Russian-Japanese war, but in fact, the Russian Pacific fleet was basically trapped in Vladivostok before the war. The Black Sea Fleet and the Baltic Fleet are afraid to take the Suez Canal because of anglo-japanese alliance. They bypassed the Cape of Good Hope in Africa and came to Asia. When they arrived, the ship was in poor condition, lacking coal and people, and parasites at the bottom of the ship greatly slowed down the ship. Coupled with a commander-in-chief who knows little about the navy, it is not unacceptable to lose the battle of Ma Haijun.

And about Hood Bismarck. Encyclopedia said that Hood's deck was weak, but all the world warships at that time were wooden decks. Of course, the wooden deck is very fragile, but then again, can this wooden deck really stop shells over 400 mm? '

No warship's deck is made of wood, but it is covered with a layer of wood, which is non-slip and beautiful. Moreover, there are not many cases in which shells directly hit the deck in artillery battles. Because in that case, the angle between the shell and the sea level is basically above 60 degrees, from the ballistic point of view, the shooter either uses the barrel with high elevation angle at close range or is extremely far away (that is, at least ten kilometers away); The main guns of battleships generally don't have a high elevation angle, and Hood is a product of the late World War I, when there was no radar, it was a move to rely entirely on optical rangefinders for long-distance shelling. I can only say that I was hit by bad luck. Hood is battle cruiser, and the original protection target of armor is not the main gun of warship, so it is normal that the deck armor is poor.
