And the third point is actually not difficult to solve, the easiest way is to switch to a less sensitive fuse, of course, this degree is not too easy to grasp, during World War II, the torpedo fuse is sensitive to the waves can be detonated only in Japan, but the torpedoes produced by other powers have another serious problem, that is, after the torpedo hits the enemy ship, it often cannot be detonated for some reason, and the trigger type is limited by the angle when hitting the enemy ship, and the magnetic induction fuze is even worse because the jishu was not mature during World War II

In this regard, Hu Weidong decided to take a two-pronged approach, while engaging in low-sensitivity triggered torpedo fuse emergency, but also let Tesla, the "king of electromagnetism", devote a little energy to lead a group to try to produce magnetic induction torpedo fuses, which can succeed best before victory, even if it is not used in the war, it can be regarded as a jishu reserve, after all, the potential of magnetic induction torpedo fuses is greater, and Hu Weidong himself can also provide a little idea and even jishu help. Although opening two research groups at the same time will disperse manpower, anyway, the design and construction of torpedo boats cannot be accomplished overnight, so there is no need to rush

The performance of the hydrofoil is excellent, but the construction cost is much higher than that of conventional boats, so Hu Weidong decided that this scheme should only be used for the time being, which is very powerful and has relatively high requirements for seaworthiness (before the invention of guided torpedoes, the stability of torpedo boats directly affected the accuracy of torpedoes). patrol gunboats, submarine hunters, minesweepers, minelayers and most of the landing craft all adopted the traditional design, because the Qingdao shipyard (the name "shipyard" did not conform to the custom of later generations, Hu Weidong changed it to "shipyard", and besides, it should not have existed only as a shipbuilding base). It was already capable of producing small ships of less than 500 tons, so it could be put into production as soon as the design was completed. If you want to say that you have to thank Shen Honglie for his efforts when he was the mayor of Qingdao, without him, Qingdao would not be able to build even a small gunboat, and before that, both the Germans and the Japanese, every time they evacuated, they would completely destroy the naval base they had built, including the shipyard, and it would not be left to the next master of Qingdao at all

It is worth mentioning because of the need for anti-submarine. The Sonar Research Institute has also been established recently, and the Guidance Research Institute, which has been classified as "Top Secret", has added a new project of acoustic self-guidance (which has been studied for cable guidance for a long time) to the project. As for mine-sweeping and mine-laying, it is impossible to talk about it at present, because the Central Plains Border Region does not yet have the production capacity of mines, and it is said that the manufacture of mines is much easier than torpedoes. But trigger mines are too simple to sweep away. Basically, it was not very useful, so Hu Weidong gave the scientific and technological personnel of the Fuze Research Institute the task of developing water pressure, sound and magnetic fuzes. Of course, this is also because even for the same type of fuse, the design used in a mine is much simpler to manufacture than a torpedo

In other words, Hu Weidong is now increasingly aware that those things that seem high-tech only need to be led by cutting-edge talents at the Shijie level, plus the necessary equipment and a small number of experimenters. It will not be difficult to make a breakthrough. Although these conditions are not easy to meet, at least there is the possibility of quick success, but those seemingly ordinary basic industries need several generations of solid accumulation, especially for a backward country with a weak foundation like China, which is also one of the important reasons why New China was able to build "two bombs and one satellite" as early as the sixties and seventies, but civilian products have long lacked international competitiveness and can only rely on the so-called "cost performance" to make some hard-earned money

In the future, if you want to hit the Japanese islands, landing ships are indispensable, considering that the boats can be built faster. In addition, the distance across the sea is not far, Hu Weidong plans to focus on landing craft, and the landing ship with a larger tonnage will not be considered for the time being, and even if there are conditions to develop it, it will only be used as a reserve for the time being. For this reason, Hu Weidong also asked people to carry out research on air-cushion landing craft, so that at the very beginning of the landing operation, a superiority in troops could be quickly formed. After all, it is already very difficult for China to land in the case that the navy cannot be completed quickly, and if it drags on any longer, it will be driven into the sea if it is not careful

The jishu difficulty of hovercraft research and development is actually not as great as many people think. Historically, New China, which was less than ten years after the founding of the People's Republic of China, was the first to invent it, but it was regarded as a military secret at that time and was not announced to Shijie. As a result, the British robbed this first. But to be honest, the hovercraft is an epoch-making invention, but although it has many uses in the military, it is not enough to make a qualitative change in China at that time, so it is not necessary to keep it secret, but it is no wonder that China has lagged behind for so many years, and it is rare to have a shijie first, and it is easy to understand if you are excited. But Hu Weidong, who knew this history, naturally did not keep it too secretive, which can be seen from the fact that he even asked Tupolev, a foreigner, to participate in the development

The arrival of Tupolev and Sukhoi, in addition to their own value, convinced Hu Weidong that his ideas for China's industrialization were completely feasible. In the past two years, Hu Weidong has been thinking about a problem, the introduction of the most advanced foreign equipment and technology is extremely difficult, to be able to introduce the equipment that is currently widely used Jishu is already very good, and if the imitation is only the existing mature products abroad, it is only ten years lower than abroad. In addition, China's industrial and technological foundation is too weak, and the time for digestion and absorption is relatively long, and the gap of 30-50 years has been opened all of a sudden, while those developed countries will not stop waiting for you, so it must be very hard to catch up, and it is easy to fall into the dead cycle of continuous imitation, which affects the ability of independent innovation.

Therefore, Hu Weidong has always tried his best to directly invite foreign experts to China, and after inviting them, let them study the most advanced scientific and technological topics in the correct direction indicated by themselves, while the number of Chinese students who are at least dozens of times that of him will learn by doing, so that what they directly learn is the most cutting-edge science and technology, and there will be no dilemma of finding that what they have learned has fallen behind the times after they have learned it is not easy, and the efficiency is much higher than simply copying the current equipment and products abroad. In addition, at present, Shijie is only the three major engineering disciplines unique to China (systems engineering, parallel engineering, and reverse engineering. China's industrialization will certainly be much faster than it has historically been
