Ustinov could not but be surprised, although the conversation just now was full of clouds and fogs, Ustinov could understand that wherever the oppressed nations need to be liberated, our overall situation is there, but to put it bluntly, we want to give greater support to Vietnam.

Ustinov was not surprised by this, after all, China and Vietnam were separated by a strip of water, and helping the Red regime in North Vietnam resist the French colonial occupation was of great strategic significance to China's stability in the southwestern rear.

Because of this, as early as 1950, just after the liberation of Chinese mainland, the Chinese top leadership sent a high-level military advisory group at the request of North Vietnam to assist the inexperienced North Vietnamese guerrillas in resisting the overwhelming French offensive.

However, before the North Vietnamese army trained by the Chinese military advisory group could do anything, the North Korea suddenly ignited the flames of war, and the huge supplies that had been used to unify and stabilize the southwest had to be quickly transferred north, so that the North Vietnamese could only temporarily take the defensive.

In this way, two years later, the Korean war was still raging, and the Baiyun Factory, which was in charge of supplying North Korean armaments, turned its attention to Vietnam.

That is when the Korean war is coming to an end, and Vietnam will inevitably become another major battlefield for China to resist the infiltration of Western imperialism.

Of course, this is only one of the reasons for Ustinov's amazement, and the most unbelievable thing for him is the courage of the Chinese side, which actually hopes to use the latest weapons and equipment to aid Vietnam, and does not hesitate to exchange the core technology for the concessions and support of the Soviet Union.

What do the Chinese want to do? Do you want to use Vietnam as a weapons testing ground?

Ustinov guessed correctly, Bai Yi really wants to use Vietnam as a testing ground for new weapons, others don't know, but Bai Yi, as a traverser, knows that in the next 20 years, the war in Vietnam will become more and more intense, and the two superpowers, the United States and the Soviet Union, are competing to put their advanced weapons into the battlefield, which will have a major impact on the development of weapons and equipment of the two countries.

At first, as a classic second-generation aircraft, the F-4 was influenced by the high-altitude and high-speed and missile omnipotence theory when designing, so the F-4 followed these two ideas in the aerodynamic layout, overall structure, and armament selection.

So much so that even the most basic aircraft guns were not installed, because in the opinion of the designers, the F-4, which was equipped with the "Sidewinder" air-to-air missile, did not need such primitive weapons as aircraft guns at all.

As a result, in the air battle with North Vietnam, the pilots of the F-4 were stunned to discover that the "Sidewinder" air-to-air missile, which had been praised by arms dealers, was not mature at all, and NATO's MiG-21 only needed to make a few large overload maneuvers to shake off the dull "Sidewinder" air-to-air missile.

At this time, if the F-4 has an aerial gun, it can be completely stepped forward to make up the knife, but unfortunately the F-4 has no aircraft gun at all, and there is no way to make up the knife, and in the end it can only be bitten by the tail of the MiG-21 with a smaller turning radius and shot down!

The U.S. military, having learned from the painful lessons, finally summed up the "flight optimization theory" from the tragic lessons of the Vietnam battlefield, established a perfect mathematical model, and finally applied it to the third-generation fighters F-15 and F-16, thus establishing the absolute air supremacy of the U.S. military in the post-Cold War era.

Bai Yi does not have the ambition of the US military to dominate the world, but he does want to prove the true ability of his weapons, and Bai Yi is a little helpless.

Since the Soviet Union began large-scale assistance to China's military industry and technology, the call for industry and the military to use mature and reliable Soviet-style equipment has become louder and louder.

Although high-level leaders such as the chief of armaments and the 102 chief still strongly advocate independent research and development, in the face of the general policy of Sino-Soviet friendship and the excellent performance of Soviet-style equipment on the Korean battlefield, many leaders still tend to use Soviet-style equipment.

The two sides discussed for a long time but remained deadlocked, and in the end, the high-level could only send a research team to visit more than a dozen key military factories across the country, including the Baiyun Factory, and the final conclusion was very frustrating.

That is, with the capacity of these factories alone, they cannot even meet the most basic firearms replacement of the troops, let alone heavy equipment with higher technical requirements.

Based on this, the research group came to the conclusion that it was recommended that the troops adopt Soviet-style equipment with mature technology and more guaranteed production quantities, so as to complete the leap forward in the initial standardization of the national troops.

As soon as this result came out, the chief of armaments and the chief of 102 could only fall into silence, and finally could only tearfully cut a large number of equipment research and development projects that overlapped with Soviet-style equipment, such as the 6.5mm intermediate power bullet depth modification, the Type 50 automatic rifle serial improvement project, the general-purpose machine gun project, and the light artillery project, which were declared by Bai Yi, so that the saved funds could be used for the procurement and imitation of Soviet-style equipment.

And this is also the main reason why several weapons and equipment projects presided over by Bai Yi will be cut again and again.

In such an unfavorable situation, Bai Yi did not think of a way to crack it, but in the face of Repin's constraints inside, there was the pervasiveness of Soviet-made weapons outside.

It is difficult to break the current predicament by shouting the loud slogan of independent research and development alone, and only by coming up with excellent things and achieving good results in actual combat can we get due recognition and respect.

However, as the Korean War is coming to an end, where can there be a stage for Chinese weapons to be displayed?

So Bai Yi could only move his gaze south, and finally landed on the place called Vietnam.

Since he has a goal, he will act immediately, Bai Yi is not a person who drags mud and water, so he first threw out the investment casting process in exchange for the required precision forging machine, and then exhausted his efforts to change the precision forging machine to a cold forging machine, in order to use this core technology in exchange for concessions from the Soviet Union to Baiyun Factory in supplying Vietnam with new weapons.

Ustinov didn't know what Bai Yi was thinking, even if he knew, he would probably laugh it off, exchanging core technology for the Soviet Union's support for China's new weapons to assist Vietnam was not a condition at all in Ustinov's eyes!

An inconsequential promise, in exchange for key equipment to increase the strength of the Soviet army, if this is also a condition, Ustinov does not mind agreeing to ten or eight more.

As a result, the following negotiations were unusually smooth, and the Chinese side did not make any excessive demands except for the two requirements of increasing the Soviet side's military technical assistance and retaining the manufacture of cold forging machine servo systems.

Ustinov was really satisfied with China's conditions, and it was the established policy of the Soviet Union to increase China's military technical assistance, otherwise how could China become a downstream supporting party of the Soviet Union? As for the so-called servo system made in China, it did not exceed Ustinov's bottom line, you must know that he came over this time, he was ready to cut the meat, and now the meat has not been cut, but he has gained great benefits, how can there be no reason not to agree?

Because of this, Ustinov was even more positive than the Chinese side in signing the agreement, for fear that China would regret it after the negotiations, so as soon as the negotiations reached a preliminary intention, he hurriedly signed the agreement and returned to China.

Watching the Soviet plane painted with a red five-pointed star take off, the head of armaments tilted his head slightly, looked at Bai Yi, who breathed a long sigh of relief, and snorted coldly with a solemn expression: "Look at what you tossed, are you satisfied now?" ”
