The Rise of the Empire

"The only weapon in World War II that kept me up at night was U-boats." - Winston Churchill. Let’s not talk about whether this is an exaggeration, nor about Churchill’s state of mind when he said this. As a time traveler, the only thing the prince can be sure of is that World War II is not the most suitable era for u-boats. And there is only one era when U-boats can really be used as a strategic weapon comparable to atomic bombs, and that is World War I, which is about to break out in 12 years! In this era, a large number of u-boats is very difficult to crack! \u003c/p\u003eIf the total tonnage of the German submarines sunk in World War 1 and World War 2 was high, it is naturally higher in World War II. The total tonnage of ships killed by u-boats in World War 2 was about 20 million tons . The total tonnage of merchant ships sunk by German submarines in World War I was 12,284,000 tons. In addition to the total tonnage, the performance of German submarines in World War I was far better than that of World War II submarines. \u003c/p\u003eIn terms of the number of ships sunk, German submarines in World War I sank 5,282 merchant ships, and World War II submarines destroyed about 5,400 ships. In fact, it is about the same in number. The big reason why the submarines performed better in World War II is that the ships in World War II had a larger tonnage, so if a ship is also sunk, the deadweight tonnage lost will be greater.... \u003c/p\u003eIf you put aside the overall situation and look at the efficiency of submarines, then the efficiency of World War I submarines is much higher than that of World War II. First of all, from the analysis of Germany itself, Germany had only 44 submarines before 1915. Note that this is the number of submarines that can be put into use. In fact, only 29 submarines are available, 7 from u30 to u36 The submarine has been launched, is being fitted out, and is expected to enter service by the end of 1914. Another eight submarines were planned to be launched by the end of 1914. Moreover, among these submarines, the first 18 are gasoline engine submarines, and most of them are offshore submarines, which are actually not suitable for the mission of breaking diplomatic relations. \u003c/p\u003eDuring the entire World War I, Germany built a total of 330 submarines, and in the end 176 submarines survived, and a total of 178 submarines were lost. And these surviving submarines are not equal to the usable state, because when calculating this number, it is calculated according to whether the submarine has the ability to move, and the available submarines in Germany have never exceeded 140! Before October 1916, there were never even more than 100 ships! \u003c/p\u003eIn terms of the scale of submarine operations, the German submarines of World War I and World War II were not at the same level. At the beginning of World War II, there were not many submarines, but there were 57 usable submarines. Then in March 1941, the number exceeded 100 for the first time. Then the number of submarines continued to climb, and in October 1941, the number of submarines on the list reached 200. Just 4 months later, in April 1942, the 300-ship mark was exceeded, and after January 1943, the 400-ship mark was exceeded! Subsequently, although they were repeatedly strangled by the sea and air forces of the Allied Powers, the number of registered German submarines has always exceeded 400! This inventory alone is larger than the construction of all German submarines in World War I! \u003c/p\u003eIn terms of construction volume, since 1942, the number of German submarines under construction has been maintained at around 20 per month. As time went by, in September 1944, the number of German submarines built this month reached As many as 29 submarines were built in various shipyards. In the end, the Germans built more than 1,000 submarines, and the total construction volume was several times that of World War I. The tonnage of submarines is generally much higher than that of World War I, but with three times the number of World War I submarines, the number of merchant ships sunk is almost the same as that of World War I submarines. It has to be said that the efficiency of German submarines in World War II is much lower. \u003c/p\u003eIn fact, for every submarine lost in World War I, the Allied Powers would lose 30 merchant ships with a total registered tonnage of 69,000 tons.

This result is 8 times and 4 times that of the German submarines of World War II! In other words, each German submarine in World War II could only exchange about 4 merchant ships and a merchant ship with a tonnage of about 17,000 tons. If we use Doenitz's theory of tonnage warfare, the efficiency of World War II can be described as horrible. describe! \u003c/p\u003eAs for the ace, the German submarine ace in World War 1 is still stronger than in World War 2. Major von Arnaud de la Perrier, the most nb in World War 1, can be called the most terrifying captain in the world , Sunk a total of 194 merchant ships in his lifetime! Created an astonishing record of 453,716 tons! \u003c/p\u003eThe most powerful captain in World War 2, Otto Krezimer, sank a total of 47 transport ships before he was captured, with a total of 274,386 tons. The number of ships sunk is only the former The tonnage is only about 60% of that of the former. If the ships of World War II were not generally larger, this data would be even worse.... In fact, even with this buddy's skill, he can only rank fifth among the submarine aces in the first battle, let alone the other submarine aces in the second battle! \u003c/p\u003eIs the German World War II submarine technology advanced? This is natural, whether it is wolf pack tactics, the concept or effect of using land-based long-wave radio stations to fight with submarine groups is quite good. The use of the Enig cipher machine made the communication of German submarines an almost unsolvable puzzle for a certain period of time! \u003c/p\u003eHowever, there is a saying that strength is relative. The tactics and technology of German submarines in World War I were much worse than World War II, but the anti-submarine technology and anti-submarine effectiveness of the Allies in World War I were relatively The battle is not even as good as scum, let alone the tall sonobuoys, radars, acoustic torpedoes, b17 anti-submarine aircraft, and active sonar in the 2nd battle. Not to mention the ferocious hedgehog bombs, various sound mines and so on. Don't talk about sonar at the beginning of World War 1, there are not even hydrophones. The probability of success in hitting a submarine with naval guns and hulls is greater than the probability of using mines and submarines. \u003c/p\u003eIn fact, for the German submarine officers and soldiers, they did not feel the anti-submarine pressure of the Allied Powers at the end of the war. Love is their worst enemy! The monthly loss of German submarines has always been less than 10 ships, and the British mines have made the Germans comment that "don't be afraid, this thing generally won't explode...." Of course, after the British imitated The situation changed after the Germans' new type of mine triggered. When breaking through the minefield, the Germans also invented a kind of concrete injected into the front of the hull as a "mine clearance submarine". \u003c/p\u003eTo what extent did the Allies of World War I start anti-submarine broilers? More than 90% of the surface sailing time can no longer simply explain the problem. The best weapons used by German submarines in World War I were not those fishes that could cause problems after a few rounds, but the deck guns on the submarines! Whether it is 88mm or 105mm, it is fatal to almost unarmed merchant ships, and the Germans later specially installed 150mm deck guns on submarines, so that they can also fight against slightly armed merchant ships. beated. \u003c/p\u003eThe second one is here~~~!
