No matter how many guns there are, if there is not enough ammunition, it is just scrap metal, and I don't know if the memory of the lack of bullets is too deep, or the demand for militia training is too great, China's ammunition production continues to increase even after the peace, in 1943 China produced a record more than 10 billion rounds of ammunition, even the wealthy United States can not compare. What is even more terrifying is that more than 8 billion of these bullets were used up that year, of which the militia accounted for the lion's consumption, which shows how rigorous China's militia training is, and the annual production of more than 50 million grenades and more than 30 million mines also illustrate the same problem

Due to the limitation of national strength, China cannot rely mainly on aircraft and artillery to anti-tank like the traditional powers, so the 40mm rocket launcher with high quality and low price and easy to carry has become the focus of production, and the output of China's 40 rocket launcher has reached more than 150,000 units in 43 years, and the total number of units is more than 400,000 units. In terms of operators, the second-level reserve and above have carried out practical operations, and even ordinary militiamen have received education in theoretical knowledge, and the propaganda slogan is "everyone learns to fight tanks"

There is also a slogan that is as deeply rooted in the hearts of the people as it is, but the production of large-caliber anti-aircraft guns has too high requirements for the industrial base, and even if China is no longer what it used to be, it is still difficult to balance production and quality. Therefore, in 1943, China's production of anti-aircraft guns with a caliber of more than 75mm had just exceeded 300, and even if you count the navy's ship-based anti-aircraft guns, there were only more than 400 pieces, even if they made full use of the captures in the previous wars. The total number of guns in possession is only more than 1,000, which is not comparable to those old powers that can produce thousands or even thousands of large-caliber anti-aircraft guns every year.

Therefore, at present, China's ground air defense is still relatively easy to produce small-caliber anti-aircraft guns and even anti-aircraft machine guns as the core, but even anti-aircraft machine guns, the annual output has not exceeded 10,000 units, so compared with "everyone learns to fight tanks", "everyone learns to fight planes" can only be a slogan. It is precisely because of this that Hu Weidong is in a hurry to get the jet plane, because the number cannot compete with the powers, and it must have the advantage of performance.

In fact, the idea of national defense construction in this time and space of New China is actually "tactically to make up for quality with quality." Strategically compensate for quality with quantity. ”。 In other words, if it is only a local war with a limited scale, then even if the number of Chinese jishu weapons is inferior to that of the top powers, it can rely on more haode performance to gain an advantage on the battlefield. This is quality making up for quantity; However, if a never-ending war breaks out with the top powers, the country will be destroyed. Due to the backwardness of China's science and technology and industry as a whole. Even if the performance of the Jishu weapon is temporarily superior, it will eventually be depleted by the enemy due to insufficient production capacity, so in this case. We can only go back to the old way and rely on the people's war to contend with the enemy, which is to make up for quality in quantity

When it comes to jet aircraft, the key lies in the jet engine, and Hu Weidong withstood the huge pressure to protect Wu Zhonghua did not disappoint him, in 1943 China's first jet flight was successfully tested, although this time is much later than Germany and the United Kingdom, but we not only have a higher starting point, the design of the aircraft is directly modeled after the successful model J-5 in history, and the pace is also more stable, China's first turbojet engine was finalized in the same year and began mass production, even with Hu Weidong's caution, They are sure that China's J-2 jet fighter will be finalized and start mass production in the coming year, and it will surely achieve a greater performance advantage for China than the original J-1, and in terms of reliability, its mature design can burst out of a large number of innovative products with foreign problems

Like the aircraft, China's first main battle tank, which was born from the Type 59 tank, is not far from being finalized and put into active service, although Hu Weidong does not know what kind of modification Germany will make after getting the design drawings of the Type 59 tank prototype, but he is sure that it is definitely not as good as the current Chinese research and development, because this new tank will be used for the first time in 1943 after a major breakthrough has been put into practical application of the composite tank armor and high muzzle velocity smoothbore tank gun, these two key jishu, The equally important two-way stabilizer has seen the dawn of practical application after continuous shiyan and improvement, once the tank has the ability to shell on the move, those active tanks that need to stop before shelling are exactly the same as targets in front of them. As for the "three defenses", Hu Weidong's choice of self-use version has this requirement in its design

In addition, the infrared night vision device project led by Dr. Xiong Dazhen finally bore fruit after seven years of arduous research, and directly skipped the stage of active infrared night vision device, and directly developed a more practical passive infrared night vision device, which made the PLA's night combat ability at the forefront of Shijie to a higher level. After learning the good news, Hu Weidong couldn't help but show a relieved smile, in the past seven years, he has resisted the pressure and has been supporting this fruitless project, and even has a bad relationship with him because of the purpose of protecting Xiong Dazhen (because Hu Weidong has always publicly said that he is a nerd, Xiong Dazhen will naturally not be happy when he learns about it, but he doesn't know that this is all to protect himself who has been unscrupulous in his words and deeds), and now he has finally received the results.

Xiong Dazhen was able to make achievements in scientific research and make significant contributions to the country, and the happiest thing was actually Professor Ye Qisun, who was named a master and apprentice and a father and son. In fact, the reason why Hu Weidong attaches so much importance to Xiong Dazhen, a "nerd", is because his academic level in infrared imaging is the first in China, but the more important reason is for Professor Ye Qisun.

Professor Ye Qisun has a noble character and does not have the stinky problem of the old literati looking down on people, and his temper is not bad, it stands to reason that there will be no misfortune in any environment, but Xiong Dazhen is his only weakness, in the early days of liberation, under the relatively tense political atmosphere in the country, his casual words and deeds are easy to attract trouble, and it will not only hurt him, but also Ye Qisun. Now Xiong Dazhen has matured a lot more than when he was young (Note 1), and has become the founder of a new profession, and he should not suffer from historical misfortune in the future, and if he doesn't have an accident, Ye Qisun won't have an accident, Ye Qisun won't have an accident, and Hu Weidong's group of scientists from Tsinghua University can work with peace of mind

Note 1: It is said that Ye Qisun was actually this character when he was young, and later realized his character flaws because of a painful lesson and quickly matured, and then became a generation of famous teachers admired by everyone, maybe it is because of this similarity that he is particularly fond of Xiong Dazhen, right?
