Passive guidance is a backward technology in modern times, because it needs to maintain illumination of the target at all times. If something unexpected happens on the way...for example, the laser-emitting fighter plane is attacked by the enemy or the launch is interrupted due to other circumstances, then the missile will
Lost target.
But this was during World War II, and this guidance technology, which was considered "backward" in modern times, was considered advanced at this time.
It's just that this thing is much more difficult to implement than TV guidance... First, it needs to move the high-power laser emitting device to the fighter plane. Secondly, it needs to maintain illumination when the missile arrives nearby. Thirdly, there needs to be a computer inside the missile.
The received laser light is evaluated.
But all of this is worth it. Once it succeeds, the threat of Japanese warships can basically be ignored.
So the plan was immediately decided, and the research on anti-ship missiles was divided into two directions:
One is television guidance, which is used for emergency purposes in case there are no missiles available when attacking Fengtian.
The other is laser guidance. This is a long-term research and development plan, but it must be realized at the latest before the Japanese know how to use jammers to deal with TV guidance.
As a result, the institute was very busy: air-to-air missiles and anti-ship missiles were developed at the same time, which had never happened in the history of the institute.
Due to the serious shortage of staff in the institute, Su Xina could not arrange the manpower.
For example, Su Liguo is a radio expert, and whether it is an air-to-air missile or an anti-ship missile, all require radar and radio. He is also responsible for miniaturizing transistors, so he runs around in the three heads and wishes he could break one person into two people. Sometimes it is difficult to rest in the middle of the night.
After a while, I will be called up to catch up on the project.
It's not just Su Liguo who is in this state. Chen Jiefeng is in charge of the computer, and He Zhimin is in charge of the flight control. They all have to run both directions, and they only sleep two or three hours a day during the busiest times.
This is a bit cruel for R&D personnel, but Wang Xuexin has nothing to do.
Who told us that this is a war era?
And there are still so few talents, so we have to go all out to win!
Sometimes, Wang Xuexin is glad that he has trained this group of talents before. Otherwise, if he were alone now, he would have no idea where to start even if he had a system to protect him.
All Wang Xuexin could do was to do his best to provide them with better food to maintain their strength.
Occasionally meeting those R&D personnel who were extremely tired, Wang Xuexin asked them if they were suffering?
They always answer:
"What kind of hardship is this? We just need less sleep!"
"That's right, the soldiers are still bleeding and dying on the battlefield. What does this mean?"
"If we endure more hardships, we can win the battle and sacrifice fewer comrades...it's worth it!"
…
It’s the dedication of the older generation of scientific researchers. What they compare is not whose job is comfortable or whose job is respectable or whose salary is high, but what they compare is whether it’s worth it or not. What they compare is how much effort they put in!
To a certain extent, salary is meaningless to them, because they don’t even know if they can still live in this world tomorrow. Maybe a Japanese fighter plane suddenly appears in the sky or a group of mainland troops rush into the research institute and another
Or die suddenly due to fatigue...
Selfish people think about themselves more at a critical moment in life, because they think everything else is meaningless.
Selfless people, the more they think about others at this time, because they think they don't have much to give, and they should use their remaining energy at the last moment.
The headquarters is also very satisfied with Wang Xuexin’s research and development plan.
When the chief saw the telegram, he nodded with satisfaction and said to the chief of staff: "Let me tell you, this guy must have a way! I didn't expect him to think of it!"
The chief of staff sighed: "I used to think that it was almost over if missiles could produce anti-aircraft missiles. I didn't expect that this guy was actually producing air-to-air missiles and anti-ship missiles. It seems that there is still a lot of room. Missiles are something that makes
He is so good at playing that he can hit anything from the sky to the earth!"
The chief added: "And it's advanced equipment designed to fight enemies!"
As they spoke, the two looked at each other and smiled.
They knew that if air-to-air missiles and anti-ship missiles could be successfully developed, it would probably not only be a matter of capturing Fengtian, but also a matter of promoting the entire process of the war of resistance.
Because in other directions in China, this combination of air-to-air missiles and anti-ship missiles can also be used to drive the Japanese out of coastal areas.
If the Japanese lose their occupation of the coastal areas, on the one hand, the Japanese will be cut into several parts, and on the other hand, China will be able to easily break through the Japanese blockade.
Getting assistance is much easier.
Therefore, although the chief has many things to do, he is paying attention to the research and development of these two new pieces of equipment every day.
A week later, the research and development work really encountered a difficulty.
This difficulty was raised by Su Xin, who is responsible for the scheduling and work summary of the entire R&D team. One day she accidentally looked through the flight performance data of the "High Fire" and immediately came to Wang Xuexin with the documents.
"Captain!" Su Xin handed the document to Wang Xuexin and asked: "Is the accuracy of 'Gaohuo' very poor? Sometimes it even deviates from the target by more than ten kilometers?"
"Yes!" Wang Xuexin nodded while signing the document: "A dozen kilometers is still a few kilometers, and some may be farther than twenty or thirty kilometers... There is no way, if this thing is hit by unpredictable strong winds on the way, it will
It doesn’t know how to return to its own trajectory, it can only maintain its flying attitude!”
This can be said to be one of the side effects of the long range of "high fire": the farther the range, the more serious the problem of "a slight difference of a thousand miles".
Then Su Xin asked: "So, how can we ensure that 'Gaofei' can fly near the enemy warship?"
Wang Xuexin was stunned for a moment, and then stopped signing the document.
Su Xin is right. Fighters can indeed control and even guide the "high fire", but if the "high fire" deviates from the target by more than ten kilometers... it will be far outside the control range.
Wang Xuexin's first thought was to shorten the missile's range. To be precise, he wanted to get the missile as close to the target as possible so that he could hit it more accurately.
But this idea is not realistic.
The range of the Japanese warship's main gun is at least thirty kilometers (note: the range of the Yamato battleship's main gun is 42 kilometers).
This means that the Eighth Route Army's defense line must be more than thirty kilometers away.
Then the range of the Japanese infantry artillery is about 20 kilometers, so the "high fire" must be deployed at least 50 kilometers away.
A launch of more than fifty kilometers will still miss the target by several kilometers. This still does not meet the requirements, unless quantity is exchanged for quality, and dozens of rounds are fired, some of which enter the control area... But this is too efficient.
Low!
Damn it, I was so busy that I didn't even consider the issue of accuracy.
