The emergence of submarines in history at the end of the 19th century was a weapon that the United States invented but was developed by European countries. However, after the emergence of submarines, they did not know how effective the submarines were for a long time until the outbreak of World War I. The submarine warfare in World War I was much more intense than that in World War II, and the impact of the German submarines on Britain was much greater than that of German submarines in World War II.

The German submarines in World War II had two happy times. The first time was before 1941. Before that, because of the European war issue, Britain's focus was not on escort, which caused great losses to British merchant ships. However, as France surrendered to Britain, the focus of Britain gradually became on the sea. The strengthening of anti-submarine and escort measures caused the German submarine's performance to plummetly decline after 1941. After all, submarines could not compete for sea control. The sea control power was in the hands of Britain, and the merchant ships were all from Britain, and the initiative was in the hands of Britain.

In fact, the performance of German submarines was already quite bad before the Pacific War. This was mainly because Britain summarized a complete set of anti-submarine escort experiences at this time. The participation of the United States in the war brought a second happy time to German submarines. The United States did not listen to British warnings at the beginning and even had no control of the lights in cities near the coastline. The consequences were very serious. The United States, which had just joined the war, was sunk many merchant ships until the United States adopted the experience summarized by Britain.

In fact, the German wolf pack tactics during World War II mainly provided an idea. In order to achieve strategic goals according to the requirements of wolf pack tactics, only the later nuclear submarines have this opportunity. Conventional submarines cannot completely block an island country with strong industrial strength. The most successful blockade during World War II was the United States blockade of a certain island country, but this blockade was the result of the blockade of submarines and surface fleets together.

There are no nuclear submarines in this world, they are conventional submarines from World War II. The combat effectiveness of such submarines is very problematic. In fact, although the conventional submarines are also very important before crossing, they are really average. Because they are not a weapon of the same level as nuclear submarines, the advantages of nuclear submarines are all-round. Nuclear submarines are relatively large because they are nuclear power, so nuclear submarines can carry more complex and more powerful sonars. Because the depth of the submarine makes the concealment of nuclear submarines often much stronger than conventional submarines. The most important thing is the speed issue. The speed of nuclear submarines is faster than conventional submarines. Not to mention, they can maintain a very fast speed for a long time. This is something that conventional submarines do not have.

It can be said that the advantages of nuclear submarines over conventional submarines are all-round crushing. This is why the United States, the world's largest naval power, did not develop conventional submarines at all. It is that nuclear submarines have advantages in offshore areas, but the advantages of nuclear submarines in offshore areas are not that great. The advantages of marine monsters in this world are much greater than nuclear submarines, so conventional submarines have no way to face these monsters. The main defense goal of submarines in this world is to attack hostile warships that dreamed of little loli. Because of their slow speed, it is impossible for submarines to pursue, so they are basically sneak attacks under the protection of the island defense system.

This is basically the case in this world, because it was the submarines of World War II that made the submarines in this world terrible underwater speed. This is not the modern conventional submarines when Fatty Tail crossed. These modern conventional submarines can last for several days when they advance at a speed of about five knots. At this time, the fastest speed of conventional submarines is no longer much slower than nuclear submarines. The worst is that they are not as long as nuclear submarines. After all, conventional submarines use batteries, and the battery power will always be exhausted. Once the nuclear reactor of nuclear submarines runs, it is not an easy thing to stop.

However, Fatty Gao still hopes to get a submarine because he wants to know what the submarines in this world are like. However, in history, various countries have built many submarines. Although German submarines are the most famous and built the most, there are also many submarines in other countries, and the results of the US submarines are also quite brilliant.

In the late Pacific War, a certain number of warships in a certain island country were sunk by submarines, including the Yamato-class third ship Shinno, the Kaohsiung heavy cruiser, etc. Fatty Gao wanted to build a submarine but it was not necessarily a German submarine, but in Fatty Gao's impression, there were only German submarines and American submarines with excellent record. He didn't know much about other submarines.

It can be said that Fatty Gao is basically the same. The psychological problems of Royal Oak need a little bit of relief. Argentina's problems are not very big, but we have to pay attention. Fatty Gao stayed at the Royal Oak for a long time. For this reason, Fatty Gao also adjusted his schedule. During this period, Veneto came several times. Vereto did not want to stay at the headquarters of the Elizabeth Society, because there were always many commanders and ship girls coming to find her at the headquarters of the Elizabeth Society, and Veneto did not want to be disturbed.

However, Veneto had no place to go except the headquarters of the Elizabeth Association. In a last resort, Fatty Gao suggested that Veneto help him handle the matter. Fatty Gao's current task is to supervise the agents. Veneto took on this task when he had no choice. As the head of the Italian ship girl, Veneto did not want to intervene in the Elizabeth Association, but the problem was too many, Vereto had no choice.

However, although Fatty Gao established a determination to fight for a long time, Fatty Gao still underestimated the difficulty of the psychological problems of Royal Oak. In fact, the psychological problems of Royal Oak are her historical burden, because in Royal Oak's mind, it is necessary to be stronger than the two sisters of Ise Hinata. The most correct comparison of these historical warships in the same country is, that is, not to compare with these historical warships in their own country, they must also compete with Nevada. However, compared with Nevada, Royal Oak is indeed not good.
