Traveling through the sword to engage in military industry.

Chapter 253 The winning hand

Maowusu Base.

Ren Zhong appeared in front of Professor Qian's team again, because there would be a very special performance today that Ren Zhong needed to witness on the spot.

Ren Zhong looked at the familiar shape standing not far away and couldn't help but smile.

This is the new version of SAM-2 in the world of Sword and Fairy - the Hongqi I air defense missile. Of course, not all of it is implemented on the missile, but the original version of the fire control radar cannot be implemented, so next to it, there is also a set of the latest improved version of the SCR-268 radar - the mobile improvement weakens the early warning distance, but greatly reduces the weight from 36 tons to 20 tons, and can be installed on 6 trucks for movement.

Of course, the two cannot be seamlessly connected, so the current Hongqi I still needs remote control.

The missile is still the same missile, but the control method is quite primitive at this stage. The data obtained from the SCR-268 fire control radar is used to control the missile to hit the target by radio remote control.

In other words, this missile needs to combine the human brain, radar and the missile body to work.

This is a helpless choice made by Ren Zhong after research based on the current situation. The Fan Ge radar guided by the SAM-2 radar has not been developed for a while, and the radar research group has just digested the SCR-268, so this thing is temporarily taken out for transition.

As for whether it works or not, we will know today.

A PT-19 trainer aircraft was converted into a simple radio-controlled drone.

It took off from a remote temporary battlefield airport and cruised over the base at an altitude of about 160 meters at a speed of 3000 kilometers per hour. The radar had already searched for the PT-19's flight altitude, cruising speed, direction and other key indicators. The operating team that controlled the surface-to-air missile quickly set the launch parameters.

The missile successfully ignited and took off, began to accelerate, and then flew towards the designated airspace.

On the ground, the researchers of the remote-controlled missile stared at the sky nervously, waiting for the missile to intersect with the PT19 trainer aircraft flying slowly from a distance.

Although the direction of the missile can still be controlled from the ground, for the first launch, it was like a trip agreed upon by both parties. The missile and the PT19 trainer aircraft soon met in the air. Before the meeting, the researchers on the ground pressed the explosion button very nervously. Before the two met, the missile exploded and launched countless fragments, almost instantly igniting the PT19 trainer aircraft!
The missile combat explosion part that uses a radio fuse will produce more than 3000 metal fragments, and its killing range will be at least within a few hundred meters in diameter!
In this way, the first launch of Hongqi I was a complete success after the PT19 trainer aircraft turned into a fireball!

Although this test is quite different from the real combat environment, the Japanese fighter jets will not fly in one direction all the time.

But for now, at least the radar can detect enemy aircraft more than 10 kilometers in advance. For the air defense over a fixed location, as long as the Japanese fighter planes dare to come, this missile will become another more powerful air defense weapon besides the 88mm anti-aircraft gun and G20 anti-aircraft gun.

"Professor Qian, congratulations on your new achievement. I would like to deploy this air defense system in Taiyuan to protect the sky above Taiyuan from being ravaged by the Japanese fighter planes. From now on, this air defense system needs to be mass-produced, and the relevant operator training must also be rolled out. We need at least 100 sets of this air defense system to fully protect the skies over several of our key cities." Ren Zhong said to Professor Qian as he looked at the black smoke spreading in the sky and the falling fireballs.

Now he is the only person in charge of finalizing the system. Even though the system is still quite crude, Ren Zhong feels that it may be more useful than the 88 anti-aircraft gun.

After all, the role of anti-aircraft guns is to increase the probability of shooting down enemy aircraft by quantity.

In comparison, this air defense system has a stronger ability to lock onto targets and has greater lethality after the explosion!
Even if it is manually controlled at this stage, the effect should be much stronger than the 88mm anti-aircraft gun.

Now that Operation Zero was about to begin, Ren Zhong did not expect to rely on the more than 50 fighter planes of the Divine Eagle Squadron to ensure the safety of the entire Jin area.

The Japanese deployed such a powerful ground force, it was impossible for them not to take the air force into consideration.

Judging from the current military strength of the Japanese, if they regard Operation Zero as the biggest battle in the near future, the supporting air force will have at least several hundred aircraft!
No matter how powerful the Mustang fighter is, at this stage it is just a one-on-one fight against the Zero fighter. However, facing hundreds or even more fighters of the Japanese devils coming at them, the Mustang fighter will be unable to focus on one thing while neglecting the other, putting the sky over the city in an extremely dangerous situation.

Ren Zhong could tell with his feet that the Japanese would never miss the opportunity to bomb important factories such as Taiyuan and Lu'an.

Strategic targets such as large steel mills and heavy machinery plants must never think of avoiding the Japanese intelligence reconnaissance.

After all, it is impossible to hide these in the deep mountains and old forests. A large amount of materials are transported in and out all day long. It is basically the busiest place in various places. Even if the security work is strict, you can only guarantee the situation inside the factory, but the location of the factory and the information of in and out are difficult to hide from the eyes of the Japanese spies. So now the pressure of urban air defense is very heavy. Even though Ren Zhong has increased the production capacity of 88mm anti-aircraft guns and 20mm anti-aircraft guns a lot, and has produced more than 600 20mm anti-aircraft guns and more than 100 88mm anti-aircraft guns, it is still not enough.

Most of the more than 100 20mm anti-aircraft artillery companies currently equipped will be assigned to Type A regiments to undertake field air defense. There are less than 40 20mm anti-aircraft artillery companies left, and there are more than 10 key cities that need to be responsible. Even if more than 20 88mm anti-aircraft artillery companies are added, there are less than 10 air defense artillery companies in a large city like Taiyuan. There are too many places to defend and the loopholes in the air defense firepower are too large.

"Mr. Ren, although we have tried our best to let the rocket factory process and produce the Hongqi I, so far we only have eleven sets of Hongqi I parts for assembly, and we used up one set today." Professor Qian said with a helpless smile.

He knew Ren Zhong's habits, and for products that required detailed design information, the starting production volume was ten sets.

Because Ren Zhong has absolute confidence in these, even if the first one fails, it will definitely succeed after summarizing and fine-tuning.

Now the rocket body and propellant have reached a mature level. The Hongqi is much smaller than the Dongfeng Express and is completely a miniature version, so there is no problem in producing ten sets.

It's just that time is short. Now the missile research group has simultaneously launched two product lines, Dongfeng Express and Hongqi. After the success of Dongfeng Express I, the II generation is also being intensively developed. Hongqi is an improved branch of the I generation air defense system. The rocket itself does not have too many difficulties, but the seeking and control aspects are new topics.

Fortunately, after some hard work and with the relatively detailed basic information provided by Ren Zhong, the first generation was finally completed.

Even so, there are still several difficulties to overcome in the imitation of radar, especially those in the electronic field. Even though Ren Zhong has provided a lot of information, this field is cutting-edge today, and a lot of basic equipment has to be researched by ourselves, so the progress is somewhat slow.

The magnetron used in missile radar is still under technical research. This thing is not uncommon in the main world. Microwave ovens can be used everywhere now. Ren Zhong even dismantled the magnetrons of several microwave ovens for reference by the radar research group.

However, these basic things cannot be achieved overnight.

Just like transistor computers, although the first generation of machines are close to success, due to the lack of physical reference, they have to rely entirely on the information provided by Ren Zhong, and move forward in a blind manner, which always takes time to accumulate. Now their speed is much faster than the speed of historical research.

From 1947, when Bell Telephone Laboratories developed the first semiconductor triode (transistor), it took until 1955 to complete the research work of the first generation of 800 transistor computers. It took 8 years from scratch! my country began to study computers in 1953, starting with the study of vacuum tube computers. The first vacuum tube computer in history was successfully developed in 1958, and it was a copy of the Big Bear. The research time took more than 5 years.

Of course, this is also largely due to the incomplete information provided by Big Brother. Ren Zhong's information is complete. In comparison, there is no risk of going astray. All the work revolves around how to manufacture those transistors stably.

With current technology, this is a huge challenge, involving breakthroughs in materials. So even if it is just copying homework, it is not yet done in time.

But we are very close to final success.

With breakthroughs in key technologies such as computers and magnetrons, the shortcomings of missile automation control will soon be made up.

After conducting preliminary research on ground-to-ground and ground-to-air missiles, the rocket research team will continue to deepen their work along these two paths and will also conduct research on air-to-air and air-to-ground missiles.

In another direction, there is a special team that is working hard to study the air-to-ground rocket launch nest proposed by Ren Zhong. This is to provide a powerful weapon for the Air Force to attack the ground. It is a customized 107-pack 6mm rocket launch nest derived from the 90 rocket. Judging from the feedback, it is now basically successful. This rocket launch nest is similar to the 107 rocket in principle, but because it needs to be installed on a fighter, some re-fixation and new ignition design are required, so the progress is not too fast. However, with the main world data provided by Ren Zhong, the project team is still firmly advancing the mass production schedule.

Ren Zhong had no complaints about the work of Professor Qian and his colleagues. Basically, every job they were doing was at their limit.

It's just that the heavy sense of historical responsibility not only drives Ren Zhong to work hard, but also drives every researcher at the Liming Institute to work hard. The infrared imaging research of the Optical Research Center has been widely used in telescopes. Next, they are working hard in the guidance direction according to the information provided by Ren Zhong.

When this technology breaks through, it will also be a historic change for missiles.

It can even be said that if we are the first to break through the infrared guidance technology and apply it to surface-to-air missiles and air-to-air missiles, even if our fighter jets are a little behind the times, we will have an advantage by using propeller fighters + missiles to fight jet fighters that only have machine guns.

Therefore, Ren Zhong regarded the research and application of missiles as the real deciding factor. Now, the results have gradually begun to emerge. The surface-to-air missiles have made a great step forward in practicality and have begun to enter actual combat.
