Infrared night vision devices cannot be used by a large number of infantry due to cost problems for the time being, but tanks will definitely be installed. And with composite armor, high muzzle velocity smoothbore gun, two-way stabilizer and infrared night vision device, and with the ability of "three defenses", the 59 magic change is far from being in service and even any tank in history before the mid-60s. And even the nemesis plane of the tank, if it wants to blow up such a steel monster, it is several times more troublesome than those tanks on the current shijie

As for the biggest nemesis of the tank in later generations - the helicopter gunship, after the invention of the gas turbine, it was finally successfully put into practical use, but if it wants to achieve the status of later generations, it needs to wait until the anti-tank missile Jishu matures, although it is now possible to attack tanks with aircraft guns and rockets, but the former has too short a range, the helicopter speed is slow, and the possibility of being shot down by enemy anti-aircraft artillery fire and even anti-aircraft machine guns is not small, and the accuracy of the latter is really a bit low for a target with a small size and not slow speed like a tank. Moreover, the kinetic energy of airborne rockets is not enough to penetrate tank armor (Note 1), and anti-tank shells can only rely on armor-piercing warheads, and now that grille armor has been rapidly spread on Shijie, armor-piercing shells are far less effective than they were at the beginning

The application of gunships on warships faced similar problems, and before the invention of towed sonar, anti-submarine helicopters could hardly become a real submarine nemesis, especially those with super stealthy teardrop-shaped submarines. However, even so, after the emergence of carrier-based helicopters, they quickly replaced the water reconnaissance planes that were not welcomed by the navy because of their large space occupation and great danger, and they had an incomparable advantage over fixed-wing aircraft in dealing with the enemy's speedboats

Due to a large number of orders and jishu support from Japan. China's shipbuilding has continued to make rapid progress in the past few years, although Japan has reduced orders for military ships out of concern that China's navy is too strong, and purchased more cargo ships from China as transport ships, but the completion of the first 100,000-ton giant oil tanker still greatly enhances the strength of China's shipbuilding industry, and the construction of a 300,000-ton dock in Beilun Port in Zhejiang Province shows the ambition of the Chinese government. Of course, this is also because China has already reached the first-class level in engineering construction, you must know that even in history, China's shipyard construction has jumped from 30,000 tons to 250,000 tons and succeeded

With the big ship, some ideas that originally seemed absurd were also realized. China's Strategic Rocket Forces, for example, intend to move ballistic missiles to large surface ships for launch. In this way, its strike range can be greatly expanded.

However, Hu Weidong, who has been before, naturally knows that such an idea is impossible to realize, because ships carrying ballistic missiles are too fragile and expensive, and surface ships do not have the concealment of submarines. Unless it has absolute air and sea supremacy. Otherwise, such a "ballistic missile cruiser" is simply an active target. It has no practical value, and with China's limited carrier-based aviation force, which currently has only one medium-sized aircraft carrier, it is doomed to be unable to gain air and sea supremacy in the ocean.

But Hu Weidong did not stop the research project. On the contrary, it was agreed to allocate funds, on the one hand, because it could be used as a reserve for the future development of ballistic missile nuclear submarines, and on the other hand, to encourage the innovative spirit of scientific researchers

In 1943, China's civilian science and technology also made a lot of progress, such as significant but unremarkable materials and processes have been constantly improving, in addition to many other scientific and technological achievements are actually dual-use, not only for national defense of great significance, but also to improve people's lives, such as the use of the "plastic king" PTFE lubrication and high temperature resistance (relatively speaking) characteristics of the invention of non-stick pans are very popular with housewives

The year also saw the future of science and technology in China take place at the first National Conference on Science and Technology, at which biologist Cai Xitao was unexpectedly awarded the first prize, much to the surprise of many who thought that the Chinese government was concerned only with applied science and technology and despised theoretical technology. However, they soon learned that the reason why Cai Xitao won the award was actually related to the application in the final analysis

In 1933, Cai Xitao found a melon species that had never been seen in the records in Dawei Mountain, Pingbian, Yunnan, and its fruit could weigh up to dozens of catties, which contained several duck egg-sized seeds, and the oil content was as high as 70%, so Cai Xitao named it oil melon at that time. Oilmelon is a perennial vine, can be harvested continuously for many years after growth, the amount of labor required is less than the annual oil crop, in addition to the fruit of oilmelon can also be eaten or used as feed, and the local people have used it as medicine since ancient times, it has a good effect on many skin diseases and some venereal diseases, and the potential economic value will not be low. It's just that the country was not peaceful at that time, and Cai Xitao had no time to stay and study with peace of mind, so he didn't start the research immediately.

After the founding of the People's Republic of China, Cai Xitao was inspired by Hu Weidong's "Finding and Domesticating Valuable Wild Species for the Benefit of the People." After the outbreak of the Soviet-German war, the main source of imports was in the Soviet Union, which became more and more prominent, resulting in the government having to re-implement the ticket rationing system for edible oil, the price of edible oil in the black market was frighteningly high, and the shortage of oil and water led to a rapid increase in people's demand for food, which increased the pressure on food supply

In this case, China urgently needs oil crops with higher oil yields, and Cai Xitao couldn't help but think of the "oil melon" discovered a few years ago, and immediately applied to the institute to set up a project, and immediately returned to Yunnan with several of his students after receiving approval, and began the difficult domestication.

Oilmelons can bloom and bear fruit within one or two years after planting, and can continue to bloom throughout the year, and there are three peak periods, namely mid-March to late April, mid-June to early August, and late August to late September, with an average of more than 300 flowers per plant. However, although there are many flowers, the fruit drop rate is extremely high, which can reach more than 90%, so most of the successful fruits of a single plant are about 20 to 30, and more than 60 are extremely rare. In this case, although the oil content of the melon seeds as big as duck eggs is extremely high, the fruit is small, and the yield is naturally not high

Note 1: It's okay to hit the top, but the helicopter can't have much angle when launching the rocket, because the source of its lift is different from that of a fixed-wing aircraft, and the rocket is not like a missile that can adjust its attitude and direction when flying, so even if it hits the top of the tank, the angle of incidence will be very large, and the effect is not much better.
