What Zhao Zhongyao wants to develop now is only a weapon to deal with high-altitude reconnaissance planes, and it is a missile that can attack high-altitude reconnaissance planes.

Such a missile is relatively easy to develop. Because the reconnaissance aircraft does not fly as fast as missiles and is larger in size than missiles. In this way, it will be easier for the missile to deal with such a high-altitude reconnaissance plane.

Although it is easy, Zhao Zhongyao must first develop the performance of these high-altitude reconnaissance planes of country Y!

It should be said that the high-altitude reconnaissance plane is also an advanced weapon, like the D-21 high-altitude reconnaissance plane of the United States, which can fly to an altitude of 20,000 meters and fly at a speed of Mach 2, that is, twice the speed of sound.

The reason why this high-altitude reconnaissance aircraft is so powerful is that it uses a 'ramjet engine'. This kind of engine is not an ordinary engine, but uses the pressure generated by the air circulation itself to burn the mixed flammable gas in the fuel chamber to produce high temperatures to propel the engine to work.

More importantly, this aircraft is also an unmanned reconnaissance aircraft, which is commanded remotely at a military base.

In a certain sense, this kind of high-altitude reconnaissance plane is a kind of high-altitude reconnaissance missile! Because the shape of this kind of reconnaissance plane is designed to be the shape of a missile.

Because only such a streamlined shape can make the reconnaissance plane fly faster and higher!

As a matter of fact, the design concept of this high-altitude reconnaissance plane is precisely the experience borrowed from the principle of missile development.

Only once, the high-altitude reconnaissance aircraft was not used to attack targets, there were no explosives in it. There was only some shooting equipment, which was used to reconnoiter the target.

At that time, such high-altitude reconnaissance planes were very advanced weapons, and there were almost no weapons that could shoot them down.

This high-altitude aircraft can fly at a maximum altitude of 30,000 meters, and its fastest flight speed is Mach 3, which is almost three times the speed of sound.

At that time, when this kind of high-altitude reconnaissance plane was built, it could fly in the airspace of almost any country. There is no need to worry about the missiles of these countries being shot down.

Because this kind of plane can fly faster than a missile, even if you attack it with a missile. I found the target, aimed at the target, tracked the target, but I couldn't catch up with others, I could only watch them fly through the airspace of my own country, and there was nothing to do!

But the more advanced the weapon, the more likely it is to go wrong. The same goes for D-21. Although it is advanced, flies fast and flies high. Missiles can't hit, and fighter jets can't catch up. However, there are problems with the aircraft itself.

First of all, such aircraft are unmanned. Due to the speed is too fast. Fly high again. It would be more dangerous for people to fly it, I'm afraid that there is no pilot who dares to fly such a plane!

The D-21 has conducted reconnaissance of China's airspace four times in order to photograph some of China's military information on atomic bomb research.

However, none of the D-21's four reconnaissance missions were successful, and each one failed. On the first flight, the plane just entered the coastal airspace of our country, then deviated from the direction, and finally did not know what to do.

The second flight flew over the western part of our country. After filming some military intelligence, I once again did not know what to do.

The third flight, also obtained information, but on the time of return. Crashed in the Pacific Ocean for no apparent reason.

On the fourth flight, everything went well, and the plane had already dropped the information taken from the plane. But at this time, a strong wind suddenly arose on the sea. Make it difficult for a tracked warship on the ground to observe where the target fell. In the end, I watched the precious information and intelligence obtained from painstaking reconnaissance sink into the sea and could not do anything.

Four reconnaissance attempts and four failures made the top brass of the United States depressed and had to abandon the task of producing such high-altitude reconnaissance aircraft. There is no longer any extravagance to use this method to reconnoiter our country's military intelligence.

This may be in line with the saying 'If you do too much injustice, you will kill yourself'. Military operations with bad motives are doomed to failure, and even the heavens will deliberately cause trouble for you!

Of course, on the other hand, the more advanced the weapon, the more likely it is to go wrong, and the more difficult it is to control.

At present, the high-altitude reconnaissance aircraft of country Y are not as advanced as the old American D-21. The two are simply not comparable.

The high-altitude reconnaissance plane of country Y is just an ordinary fighter plane piloted manually. However, it is not used to compete with other fighters, but to use some high-altitude cameras to photograph the target buildings on the ground.

Zhao Zhongyao knew that the missiles he wanted to develop were designed to deal with these ordinary reconnaissance planes, and that there was no need for any 'Patriot' missiles at all. Or medium and long-range missiles like 'Scud'.

Now such a reconnaissance aircraft of country Y, with Russian-made S-300 anti-aircraft missiles, is enough. With this kind of missile, it will be completely possible to shoot down the high-altitude reconnaissance planes of country Y.

After studying some missile data and reconnaissance plane data, Zhao Zhongyao decided to design an air defense missile that was almost like the S-300.

After a month of hard work, he finally designed the drawings of the S-300. Then it was taken to the military factory and the workers started manufacturing.

After another three months of hard work, the first S-300 anti-aircraft missile was finally produced.

It is a 'cannon shell' that is about eight meters high, one meter in diameter, and weighs about five tons. Compared with the anti-tank missile developed by Zhao Zhongyao before, this missile can be described as a big guy.

After Zhao Zhongyao developed the first air defense missile, he asked Director Liu, Chief of Staff Yang, and Yan Mingcheng to visit it together.

The missiles were placed in the ordnance warehouse of the military factory.

Since this anti-aircraft missile is tall and large, it stands upright in the warehouse, and has already reached the roof of the warehouse. If this missile is longer, I'm afraid this warehouse won't be able to fit it!

When Director Liu, Chief of Staff Yang, Yan Mingcheng and Zhao Zhongyao came to the warehouse together and saw the S-300 anti-aircraft missiles produced by Zhao Zhongyao, their eyes widened in surprise.

"Zhongyao, is this an anti-aircraft missile that you have developed in the past six months! This is too powerful!" As soon as Yan Mingcheng saw the big guy in front of him, he couldn't help but be surprised!

"Oh! Is this a 'cannon shell'!" Chief of Staff Yang has never seen any missiles, and when he looks at this thing, he feels that it is a 'cannon shell'!

Director Liu looked at the big guy in front of him and felt that this thing could fly into the sky! )
