The high altitude defense system of a large foreign country is a land-based mobile anti missile interception system.
The designed missile is less than 7 meters in length and less than 0.4 meters in diameter. The missile is not as strong as the S-300 air defense missile, but it has to have a firing height of more than 150 kilometers and a range of nearly 300 kilometers.
We can imagine the difficulty.
The reason is that the army's air defense and antimissile force of a large country outside the region needs to ensure sustained fire output, so as to ensure that it can cope with the saturation attack of enemy's medium and long-range missiles.
This kind of persecuted paranoid neuroticism can be found everywhere in the history of a big country outside the region. Whether they are stubborn or stick to their own opinions, the army of this country, especially the army, is very easy to go black.
Even if it's the blood on the hit scalp.
The land-based mobile anti missile interception system is the best example. Because of the army's insistence, the missile is extremely small and cannot carry more fuel propellants, but it has to achieve a high-speed moving target 150 km high.
150 Kilometer high, you know, it has already broken through the atmosphere, the height of entering space, where is the world of satellites, and it is also the mid range flight height of medium range launch vehicles.
Therefore, the general fuel propellants can not meet the requirements of the land-based mobile anti missile interception system at all, and can only be re developed.
This research has been going on for more than ten years. During this period, it has been on and off again and again, and it is not easy to pass the standard in the aspect of fuel and propellant. The mobile impact warhead has been on the brink again.
There is no way that the size of the missile is too small to carry a larger warhead, and the mobile collision warhead is the most effective combat mode of this kind of anti missile missile.
Compared with the traditional proximity fragmentation warhead, the mobile collision warhead can make the target directly invalid in the space environment by kinetic energy high-speed collision.
Even the nuclear and biochemical targets with special charges can be destroyed directly.
Compared with this, the fragmentation warhead is much worse in this aspect, either to put the target out of the original track, or to destroy part of the target, and other incoming warheads continue to attack.
Because of this, laomaozi's method is very simple and crude. If ordinary fragments can't be killed completely, Laozi will go directly to the nuclear warhead.
However, this kind of practice of killing the enemy for one thousand at the expense of eight hundred can be described as good and harmful to one's own interests. A big country outside the territory is so valuable that it can't do so.
It can only be used on the mobile collision warhead, and the result is a chicken feather on the narrow unit.
If we don't reduce the difficulty of the test, we won't be able to intercept successfully at all.
However, the land-based mobile anti missile interception system is a chicken rib to a big country outside the territory, but it is the worst to the then Tengfei group. A big country outside the territory has at least verified the feasibility of this mobile anti missile interception system, and it is completely successful.
It's just that the army of a big country outside the region is too determined to carry 8 to 16 interceptors in its motor vehicles. Just like the Patriot series of air defense missiles, they have continuous air defense firepower. At the same time, the operating system and hardware facilities should also be universal, so as to reduce the maintenance cost and personnel training time.
In this regard, Zhuang Jianye's evaluation of the four word "dead eye"!
Anti missile and air defense are two different modes of operation. What if they are different?
Can we solve the problems first and improve them later?
Of course, Zhuang Jianye's evaluation of the scientists in the Aerospace Department of Tengfei department does not agree. They think that a big country outside China is a brave artist, and they can't do porcelain work without diamond. It is because they have a lot of technical reserves that they dare to put forward such harsh targets.
In contrast, China is not a little bit worse.
However, whether these scientists in the Aerospace Department of the take-off department are modest or really face up to their own shortcomings, they agree with Zhuang Jianye's view that if a large army outside the region increases the size of the down missile, it's better to use the size of the S-300 missile instead of more, and the so-called land-based mobile anti missile interception system has long been a success.
At the suggestion of Zhuang Jianye, the Aerospace Department of the Tengfei department put forward a bolder idea, that is, to build a mechanical air defense interceptor with a length of 8.5 meters, a diameter of 5.8 meters and a launching mass of more than 2.2 tons on the basis of the body parameters of the Russian made S-300 air defense missile.
It is estimated that the imported 8 * 8 special truck made in Russia will be used to carry 2 interceptors. After the domestic heavy 8 * 8 special truck is finalized, it can carry 4 interceptors.However, the number of two or four missiles is far less than that of the land-based mobile anti missile interception system of a large country outside the region. However, it is a qualitative leap for the air force air defense forces that used to pull the fixed red flag-2 air defense missiles and move thousands of miles across the vast territory to carry out the so-called air defense guerrilla warfare.
After all, this time it wasn't an airplane, it was a higher satellite and carrier rocket warhead.
However, the idea of the space Department of the take-off system is good, but it can not be achieved overnight. The take-off system does not have enough experience in fuel propellant, kinetic warhead or long-distance real-time control.
If you don't have it, you have to brush it.
How to brush?
Of course, Tengfei Department has its own mature experience system, that is, high-end projects and low-end projects are launched at the same time, the mature technology accumulated by high-end projects is used to enrich low-end projects, and then the customer experience gained from the performance and sales of low-end projects is used to improve low-end projects and feed back the shortcomings of high-end projects.
LYJ The 2000 air defense missile came into being under this background.
Apart from the fact that it looks very similar to the S-300 in appearance and has a feeling of domineering side leakage, it has nothing to do with the S-300 in fact, because its positioning is very low-end, which is to replace the old red flag-2 air defense missile.
Together with the S-300 made by Russia at the present stage and the red flag-9 air defense missiles in the future, it forms a high-low air defense combat system.
Because of this, the air force air defense forces have only one demand for him, and they have a large number of demands.
This requires lyj-2000 air defense missile to be a low-end air defense weapon system with cost performance.
However, although the positioning is not high, if you take apart the details of the lyj-2000 air defense missile, you will find that all of them are unique skills that are difficult to achieve.
Among other things, missiles with a length of 5.6 meters, a diameter of 0.3 meters, a firing height of 35000 meters and a range of 120 kilometers are not what ordinary air defense missiles can do.
The S-300 air defense missile made by Russia can not reach this point. Only by enlarging the missile body and loading more fuel propellants can it reach the same range and firing height as the lyj-2000 air defense missile.
Only the Patriot series of a large foreign country can be a little better. The reason why lyj-2000 air defense missile has such an index is mainly due to its new fuel propellant.
In addition, in terms of missile control and seeker, the take-off system also adds many new technologies. In addition, lyj-2000 air defense missile has strong anti-jamming ability and target damage ability.
But Zheng Quanli didn't know about it. He knew that only when Zhuang Jianye was really annoyed by him, would he say perfunctorily: "because lyj-2000 air defense missile is cheaper."
Therefore, when a group of foreign observers asked about the characteristics of lyj-2000 air defense missile, Zheng Quanli said, "what are the characteristics of being bigger? It's cheap, of course
