There is one thing that seems very unusual at first glance, and that is why the underwater wolf pack tactics that once shocked the world from World War I to World War II have not appeared since World War IIAt that time, this method of using submarines in batches and constantly passing combs in the Atlantic Ocean sank more than 30 million tons of ** and cargo ships. As a result, the shipbuilding speed of the British mainland was completely unable to keep up with the constant sinking of the transportation lines. If it weren't for the direct anti-submarine operation of the United States, which was unparalleled in the world at that time, the overseas ** and international freight of the British Island would have been completely suffocated. Submarines alone can sink 30 million tons of ships, a figure that is unthinkable today. The problem is that after World War II, there was still more than one submarine power, but why did no one do it anymore?In essence, submarine technology has improved a lot compared with World War II, but anti-submarine technology has advanced by leaps and boundsAs a result, the wolf pack tactics can no longer catch the medicine according to the prescription. Whether it was World War I or World War II,
Although the maximum depth of the so-called diesel-electric conventional submarines could exceed 200 meters, all submarines at that time were essentially semi-submersible ships. That is to say, they usually move near the semi-potential water surface, and at this time, the periscope and snorkel are raised, and while constantly observing the sea surface, they also directly and continuously start the internal diesel power to pull the net maneuver on the water surface to find the target of attack. If there is rain on the sea surface and the line of sight is not good, at this time, a number of submarine formations that form a wolf pack combing the sea will directly float on the surface of the sea in broad daylight. Unless the anti-submarine aircraft is spotted flying near the overhead, it will dive slightly to evade. Therefore, before the end of World War II, 90% of the combat operations of submarine wolves were carried out near the surface. Not only can it drive the diesel engine inside the submarine for a long time to maneuver in a wide range of the sea surface, but it can also receive and receive telegrams at any time to carry out deep-sea information coordination warfareOnly by this can there be a brilliant result of sinking tens of millions of tons. But after World War II. Technological advances in sea surface scanning radar have led to the fact that anti-submarine aircraft can be hundreds of nautical miles away
It is easy to find the snorkel of a diesel-electric submarine, not to mention the surface of a diesel-electric submarine that is semi-submersible in a large number of formations. Therefore, the wolf pack combing the sea tactic is completely nullified. Diesel-electric submarines can only be hidden underwater for a long time without showing their heads. But there was not much progress in submarine battery technology after World War II;As a result, the range of maneuver and range of maneuver of conventional submarines under water are greatly limited, and even submariners cannot breathe freely, and the combat and living environment in the submarine is very harsh. Therefore, the tactics of conventional diesel-electric submarines have become an underwater lone wolf waiting for a rabbit. At this time, needless to say, the multi-boat formation, even the coordination of 2 boats is almost impossible to complete. In the mode of waiting for the rabbit, it is difficult to attack and defend on a large scale;As a result, it is difficult for the strongest submarine team at this time to sail beyond the first island chain on their own power. Therefore, the world's largest conventional submarine fleet, which once had more than 70 ships, was also the only killer weapon that could be fought in batches back then, but the strategy was to maintain an absolute defensive position within the first island chain. As for the serial armament of AIP submarines,
It is just a fixed-point squatting in the same place in the style of waiting for a rabbit, and striving to become a mobile squatting that can move slowly, and the maximum range of maneuver will not exceed 1,000 nautical miles, and only the operations within the first island chain will become operations inside and outside the first island chain, the difference is that there is one more "outside" word, but in essence it is still a "guard" word. The retirement of the Kilo-class conventional fish accelerated after only 27 years of service, completely ignoring the fact that more than 60% of the world's active submarines are over 30 years old. It is a clear implication that the large-scale construction and service of unconventional fish today and in the future is inevitable, and the unconventional fish in principle completely break through the restrictions of the island chain and take the initiative to attack the world underwater. The great era of offense and defense has finally arrived!
