In addition to cooperating in the construction of warships, the large number of jishu, equipment and talents provided by Germany enabled China to quickly understand the Jishu of the Xiangtan-class destroyers and Jiangnan-class frigates introduced from the United States. Later, Hu Weidong took into account the development trend of warships after the war, and decided to implement the grading standards of later generations in the navy, calling combat ships with a standard displacement of 1500-2000 tons as frigates, the main task is anti-submarine, and it also has a certain air defense and sea-to-shore attack capabilities, so the speed requirements are relatively low, and the economical and fuel-efficient diesel engine is used as the main power (destroyers and above use steam turbines driven by heavy oil boilers); Combat ships with a standard displacement of 5,000-8,000 tons are called destroyers, whose main task is air defense, and at the same time has strong anti-submarine and sea-to-shore attack capabilities; And those big guys with a standard displacement of more than 10,000 tons are called cruisers, the main task is to attack the sea and shore, and at the same time have strong air defense capabilities and certain anti-submarine capabilities, and the Nanchang-class heavy cruiser has become a Nanchang-class cruiser, of course, these are all later stories

The scale of Sino-German cooperation is so large, it is impossible to keep it completely secret, especially the cooperation between the Red Party and the Soviet Union and the navy, so Germany's comprehensive assistance to the Chinese Navy cannot avoid their eyes and ears at all, on the one hand, Stalin was shocked and worried about the in-depth cooperation between the Chinese Red Party and Germany, which is completely opposed to ideology, and on the other hand, he hoped to take this opportunity to get some advanced Germans from the Red Party, especially the battleship construction jishu that he had dreamed of for a long time.

In addition, the low air defense capability of the Soviet Pacific Fleet when it was attacked by Japanese aircraft groups made Lao Maozi finally realize how great the value of the proximity fuse and the "phalanx" close anti-aircraft gun was (they had also thought about introducing them before, but Hu Weidong's price was "too high", and the Soviets, who did not fully realize the value of the two at that time, gave up). So they also want to buy these two jishu from the Red Party. It's just that the offer is still far from satisfying the Chinese side, and it is only 30 million US dollars, and it is still offset by materials. Isn't this a dispatch called Hanako?

However, what made the Red Party even more dissatisfied with the Soviets was that the Soviet Union had not long ago unjustly set aside the Red Party and negotiated peace with the Japanese alone, and although the Soviet Union really did not have any good measures against Japan's powerful navy, many Red Party members were still angry at the Soviets' selfish practices. This is especially true of nationalists such as Hu Weidong, who value national interests over ideology.

However, China's two most urgent tasks at the moment are to drive away the devils and digest the jishu equipment imported from the United States and Germany, and it is really not appropriate to turn against the behemoth of the Soviet Union at this time. However, Hu Weidong's offer from the humble people of the Soviet Union was absolutely unacceptable. Hu Weidong, who had long known that Stalin was determined to win the battleship Jishu, made full use of this to maximize the benefits for China, and exchanged the original design drawings of the two Jishu and the German Bismarck-class battleships and the Scharnhorst-class battlecruisers from the Soviet Union for a low-interest long-term loan of $300 million before the application of new materials (Note 1), which was used to import large quantities of crude oil, iron ore, and various rare minerals including uranium ore from the Soviet Union. Moreover, the agreement also stipulated that the Soviet Union must not significantly increase the prices of these products, nor can it impose trade quota restrictions, otherwise China will have the right to refuse to fulfill its repayment obligations.

Outcome. In 1939 alone, China imported at least 1 million tons of crude oil and 5 million tons of high-grade iron ore from the Soviet Union, and the following year it exceeded 3 million tons and 8 million tons respectively, which obviously exceeded the digestion capacity of China's industry at that time. You can use it again next year, but if you can't use it up next year, you can use it again the year after tomorrow! ”。

In fact, Hu Weidong's real intention was to reduce the Soviet Union's strategic reserves as much as possible in order to make it more difficult after the outbreak of the Soviet-German war, but at this time, only 10 people knew this, including him, 7 of whom were Chinese and 3 were Germans. As a matter of fact, the fact that the Chinese Red Party provided the Soviet Union with detailed information on German battleships and battlecruisers was basically a series of schemes set up by China and Germany against the Soviet Union and even the United States, Britain, and France

Hu Weidong taught the Germans China's ancient strategy of "raising oneself for oneself," and the mustache understood that the stronger the Soviet Union, the more indulgent the United States, Britain, and France would be toward Germany. However, if the Soviet Union is too strong, it is undoubtedly a huge threat to Germany, so Hu Weidong's suggestion is to let the Soviet Union develop its navy, especially the development of large surface ships such as battleships and battle cruisers. As the saying goes, if there are more lice, it doesn't itch. More importantly, if there is more investment in the navy, there will inevitably be a corresponding decrease in investment in army and aviation weapons, which is undoubtedly very beneficial to Germany. At the same time, the United States, Britain, and France were very afraid of the Soviet Union's development of a large navy, and Germany could use this to bargain with them.

Having said that, if the Soviet Union really built up a large navy, it would definitely be a great obstacle for the mustache to attack the Soviet Union in the future, but Hu Weidong told the Germans that there was no need to worry, unlike Germany's support for China's naval construction, which was all-round support, the Soviets only got jishu information, and the Chinese side also deliberately concealed some inconspicuous but very important details, with the Soviet shipbuilding industry base, it would take a year or two just to understand it. As for the construction, taking the first battleship Bismarck that Germany built again after many years after World War I as a reference, Lao Maozi will take at least four or five years, and considering that the industrial base of the Soviet Union is not as good as that of Germany, the actual time required may be longer. Therefore, when Germany attacked the Soviet Union in the future, the Soviet battleships must still be on the slipway, and the Soviets spent a lot of national strength in vain but failed to get any practical results, isn't this the most beneficial for Germany?

Note 1: However, the most difficult copycat material recipe and process are almost completely absent, Hu Weidong's reason is that the materials are directly provided by Germany, this statement is in line with the Soviet government's basic understanding of China's industrial and technological strength, so it did not arouse their suspicion.
