The Rise of the Empire

From the monthly loss of German submarines in World War II, we can clearly see the trend of the Allied anti-submarine forces increasing. This loss was actually very low in the three years from 1939 to 1941. The monthly loss of submarines in 1939 was 2.2 Ships, the number of monthly losses in the 1940s was 1.8 ships, and 2.9 ships in 1941. In the glorious moment of 41 years, the average monthly submarine population in Germany was around 158, and the loss ratio of submarines was only 1.8%! This is a very low number! But then, the good old days of German submarines were finally over! \u003c/p\u003eIn 1942, the average monthly loss of German submarines was 7.1. At this time, the monthly number of German submarines was about 333. In 1943, when the monthly number of German submarines increased to 425, the loss increased to 19.8. In the next two years, the number of German submarines almost maintained this figure, and at the same time, the loss was almost 20 ships. Of course, the monthly loss increased to 29 ships in 1945! \u003c/p\u003eDon’t forget that in 1944 and 1945, the combat scope of German submarines was greatly reduced. In 1942, hundreds of German submarines fought against the anti-submarine forces of the Allies on the vast Atlantic , and in 1943, the largest confrontation between the escort fleet and u-boats broke out in a single game in history! \u003c/p\u003eDuring the period from March 16 to 19, 1943. The two huge transport fleets hx-129 and sc-122 are combined into one. These two fleets sailing on the Atlantic Ocean are composed of more than 110 transport ships of various types. The size of this fleet can completely impress everyone. The PQ-17 transport fleet pales in comparison. \u003c/p\u003eDuring 4 days, this huge fleet was besieged by three waves of wolves and 41 u-boats, and finally sank 22 merchant ships with a total tonnage of 147,000 tons. And the German submarine only lost 1! This is the biggest victory the wolves have achieved all by themselves! But it's a pity that this is the last glory before destruction! Because in May 1943, after experiencing Black May, Dönitz decided that the submarine force would temporarily withdraw from the Atlantic waters. \u003c/p\u003eIn September 1943, when Dönitz's wolves tried to return to the Atlantic Ocean with new equipment, they had little effect. The loss of 27 submarines in October and 18 submarines in November made Dönitz Months of efforts by Ci were turned into nothingness again, so at the end of the year another retreat order was issued...  At this point, the era of u-boats in the Atlantic Ocean is over. \u003c/p\u003eAnd if you compare the performance of German submarines at the end of the war in World War I, you can find that although the number of German submarines sunk in the later period of World War I was relatively small, they still worked hard to fight each other in the depths of the ocean, such as in 1918 The U151 submarine, which was launched on April 14, under the leadership of the captain, Major Yekendorf, carried out the mission of breaking the diplomatic mission on the Atlantic coast of the United States. During the 94-day voyage, the submarine traveled 10,915 nautical miles and sank 23 merchant ships, a gross tonnage of 61,000 tons. \u003c/p\u003eIn addition to u151, there are u140, u152, u156 and other submarines. These submarines sank more than 20,000 to 30,000 tons of merchant ships. You must know that at that time, there were not many submarines in Germany capable of ocean-going voyages, and the ocean-going submarines with a voyage of more than 12,000 nautical miles had only three levels, (respectively u139, u142 and u151). All submarines that had the opportunity to attack before the war were added There are no more than a dozen ships together. The fact that so many submarines reached the west coast of the United States and achieved decent results can only explain one problem, that is, even at the end of the war, German submarines still maintained a high level of vitality. The opportunity to attack the target, but still unable to effectively destroy these submarines! \u003c/p\u003eSo,

Generally speaking, the large-scale submarine warfare of this era is quite deadly even for a big country like Britain, especially in this plane, when the United States is already on the same level as the British, what will happen to the United Kingdom without the United States in World War I? Can you get enough supplies? How can there be enough escort warships? How can the vast Atlantic be defended without American flat-panel destroyers like dumplings? \u003c/p\u003eHowever, it is still early, and the German Navy's understanding of submarines is still very backward. In this case, the prince believes that as the future head of the second largest family in Germany, it is necessary to remind Look at the German Navy. The German royal family can own a royal sightseeing yacht, so why not an underwater sightseeing yacht that can dive? A ship marked with a yacht is under construction at the Brohm-Forth Shipyard. This submarine, called the Swordfish, will be the first submarine with actual combat significance in the whole of Germany. \u003c/p\u003eSince as a traverser, it is natural for German submarines to avoid some detours. In history, Germany’s first self-use submarine u1 was launched in 1906. The surface displacement of this ship is only 238 tons, and the underwater displacement is only 283 tons. The submarine is a paraffin oil powered submarine, still using gasoline engines. The fuel capacity is only 20 tons, and the surface range can only go 1,500 nautical miles at 10 knots. In terms of weapons, there is only 1 450mm torpedo and 3 torpedoes.... In terms of performance, it has no other role except as a training and experimental boat, and the submarines of the same period have many problems. \u003c/p\u003eFor example, the gasoline engine cylinder is not well sealed, for example, there may be water leakage. Working on the submarine in the early days is no different from taking risks. The space inside the submarine is sealed, and some gasoline engines and Due to the lax sealing rubber ring of the diesel engine, the cabin may be filled with a large amount of exhaust gas, which may cause the crew to suffocate. Submarines in better condition have installed a set of gas leak detection devices to check the exhaust gas. And if not, then the crew can only find a way by themselves. \u003c/p\u003eFor example, the sailors of the British Royal Navy used their salaries to raise mice, and then threw the mice into a cabin that might leak. …. Well, being a submariner has always been a chore, let alone back then. \u003c/p\u003e On this plane, the submarine built by Brom-Foss Shipyard has a surface displacement of 500 tons, an underwater displacement of 650 tons, a hull length of 60 meters, a width of 6 meters, and a height of 3.6 meters. In terms of size, it is similar to the u9 submarine of later generations. The submarine hull uses a ship-shaped hull. When sailing on water, it is powered by 4 diesel engines. The total attack rate is 2000 horsepower. The electric motor provides power, the maximum output horsepower is 1200 horsepower, and the maximum underwater speed is about 9 knots. The fuel load is 72 tons, and when sailing at a speed of 8 knots, it has a water endurance of 7,000 nautical miles. It can be used as a deep sea submarine. \u003c/p\u003eAs for weapons, there are four 450mm torpedo tubes. 2 in the front and 2 in the rear, equipped with a total of 8 torpedoes, and a 105mm deck gun is also planned to be installed. From the perspective of firepower, this class of submarine is very close to the historical u51 submarine. But it is slightly smaller. \u003c/p\u003eThank you for the book friends who are making troubles, the first guard tank brigade, traveling slowly, and the sea is bounded\u003c/a\u003e~~~!
