These two anti-aircraft guns were almost the first real "design" of artillery since Hu Weidong's crossing, and it turned out that his level did not drop much, and he was especially satisfied that the cost of these anti-aircraft guns was quite low compared to their superior performance. However, speaking of which, in addition to the credit of Hu Weidong's design, the wide application of rare earths has caused the scrap rate of artillery steel to plummet from 780 percent to less than 20 percent, and the life of the barrel has increased several times

After testing again and again and the test of actual combat, the 7 tubes are considered to be the most reasonable match, and the final finalized "Skynet" close defense system has a rate of fire of more than 3,000 rounds per minute, and its new ammunition supply device with 1,200 rounds of ammunition has greatly improved the continuity of firepower, and in addition, the accuracy and reliability have also been significantly improved. With this weapon of close defense, even if the maximum speed of mainstream bombers of various countries generally increases by more than 50 percent in the next few years, they will still be in the face of the "Sky Net".

The reason why Hu Weidong wanted to carry out such a large modification of these two captured warships was because China did not have the ability to build large warships at present, but it was still possible to carry out a modest modification on the basis of the existing warships, so he wanted to use this to make the necessary jishu reserves. In fact, in the maintenance and modification that lasted for half a year, the business level of Qingdao Shipyard has made great progress, whether it is Jishu personnel or ordinary workers. laid the foundation for China's own large and medium-sized warships in the future, but these are all for later

Super armor can be produced because of the high-strength low-alloy steel material that surpasses the times, and the powerful new artillery is also based on new materials. However, Hu Weidong, who is well aware of the importance of materials science and technology, cannot now shift the focus of scientific research in the border areas to this aspect, because there are too few scientific and technological talents in China, and the results of material science and technology are too slow. It should not be difficult to maintain the advantage for a period of time, and it is too late to adjust the focus and strengthen the research and development of new materials after China has driven out the devils and promoted the compulsory education system nationwide

In addition to the new alloys derived from the formula process of artillery steel and armor steel in Hu Weidong's memory, the research of rare earth permanent magnet materials is also a very important topic. However, because Hu Weidong only had a simple understanding of this, and there was a shortage of talents in metallurgy and materials, it was not until December 38 that the first rare earth permanent magnet material with practical value was discovered. However, once the breakthrough opens. New results soon followed. With the super strong permanent magnet material, permanent magnet generators, which could only be made into small generators, can be built even larger. The average installed capacity of a new permanent magnet generator soon exceeded 3,000 kilowatts, and later more than 5,000 kilowatts

Although the production cost per unit of installed capacity is still higher than that of the excitation generator, the production speed is more than ten times faster. The Jihua economic model is less of an economic account, so it once again shows its advantages, relying on the almost frantic production of medium-sized permanent magnet generators, China's annual power generation has jumped from inflow to Shijie in just a few years, so that China can grow in time to be eligible to participate in the division of the World War II cake. Among them, it is particularly worth mentioning the rapid development of the aluminium industry, it is necessary to know that the largest consumption of aluminium smelting is electric energy, with enough electricity, the output of aluminum is easy to rise. As soon as the output of aluminum increases, it can replace copper as a wire material to a large extent, and as soon as the cost of wires drops, the power industry will naturally develop more rapidly, forming a virtuous circle. The Jihua economic model has a great effect on this kind of simple cycle, and it is from this that the "power miracle" happened on Chinese soil

There are recipes and processes alone, if there are no necessary raw materials. Hu Weidong is now able to show his talents, and the vigorous development of the mining industry in the border area has undoubtedly helped a lot. In addition to the mineral resources that have been able to meet the needs before, the successful self-production of zirconium and titanium and the surge in rare earth and molybdenum production have enabled Hu Weidong to produce those high-performance alloys in his memory without discount. Zirconium reserves in China are very small. There is not much in the Central Plains border area, but because the amount is very low, it is enough to greatly enhance the hardness of the alloy, and zircon is also a gemstone, also known as hyacinth, as long as you are willing to spend money, it is not difficult to buy it on the market, so it is enough to save a little use. The difficulty is refining, but as long as the jishu problem is solved, the requirements for the industrial base are not too high, so the border area will soon have production.

Titanium reserves are very large in China, and there are many distributions in the Central Plains border area, and it is especially gratifying that most of them are rutile (natural titanium dioxide), which is relatively easy to smelt. Although the smelting cost is very high, Hu Weidong only wants some titanium as a trace component in alloys such as depleted uranium, not to produce high-titanium alloys used in aerospace and other fields in later generations, so it is completely sufficient.

Rare earth and molybdenum have long been produced in the Central Plains border area, but the two are extremely widely used, basically as long as there are performance requirements of the alloy (including steel), more or less have to add a little bit to it, which adds up to a lot, and the demand is large. Fortunately, two Shijie-level mines have been developed in the border area, the rare earth mine of Baiyun Obo is well known to the later generations, and the Donggou molybdenum mine in Ruyang County was once the largest molybdenum mine in China in later generations. The molybdenum mine in the Middle East was criticized for two reasons in later generations: first, this Shijie-level mine with an economic value of 280 billion yuan was sold to private individuals by local cadres at a price of 300,000 yuan, resulting in an unprecedented loss of state-owned assets, and second, the pursuit of profits in the development process of private enterprises was the center, resulting in serious waste of resources and environmental pollution. Neither of these situations can happen under the development of state-owned enterprises, but the private model abounds, and in the long run, the losses of the people of the country are even more astronomical, which is the main reason why Hu Weidong has been extremely opposed to private enterprises for mining development for two lifetimes (the other reason is the problem of selling resources cheaply).
