At this time, contradictions broke out again between the two branches of the navy and the air force because of different needs, and I don't know if this situation occurred in the previous plane, anyway, there was a direct problem in this plane.

Of course, after there is a problem, we need to find a way to solve it, but this problem is definitely not solved by Southwest Science and Industry, this kind of coordination between the two branches of the military, at least at the level of Vice Chairman Liu can be done, now Yang Hui and Chief Wang only need to wait on the side to see the final result.

In the face of the different needs of the navy and air force, even Deputy Commander Liu could not solve it for a while: "What you both said seems to be quite reasonable, so let's listen to what the two plans are first, and then let's talk about it, if we don't even know the specific situation, there is no need for us to argue about anything here." Therefore, let's ask Chief Master Wang to introduce the differences between the two schemes. ”

It is necessary to listen to both different scenarios. Since there is this requirement, it is incumbent on Mr. Wang.

After sorting out the ideas, I think it is better to report some advanced plans first: "Two schemes, if we pursue the performance of the early warning aircraft, we can choose to use the airborne phased array scheme to design a search radar, which will steadily surpass the E-3 early warning aircraft generation from the most basic radar working mode, and there is no problem at all to reach the world's most advanced level." ”

The use of phased array radar to develop early warning aircraft, which is aimed at the last plane of the Air Police 2000, its performance can certainly reach the world's most advanced level. But then again, the performance is really advanced enough. But there is such a thing as phased array radar on the AWACS, it seems

For phased array radars. The Republic is really not a stranger at all, just like the current Second Artillery when it hears phased array radar. The first reaction was: "Project 7101? Can that thing be put on AWACS? Or do you have other options? ”

The so-called 7101 project, this is indeed the first attempt of the Republic on the phased array radar, but this thing is not used for theater early warning search, but as a more awesome national ballistic missile early defense system, that thing was developed in the seventies as an early warning radar for tracking and controlling Soviet missiles, and the entire radar is half a hill built on the antenna alone.

And the control room behind this set of radar is not too big, it is probably about eight stories high, and when the radar is activated, the electricity consumption of a medium-sized city must be there, if it is to be compared. The energy consumption is about the same as that of an aero engine.

Such a thing is definitely not something that can be used by installing it on an early warning aircraft, even if a 300-ton aircraft like the An-225 is pulled out, it is impossible to install this radar. What's more, now they are 100-ton AWACS aircraft, and it can only be said that they have nothing in common except for the phased array system.

7101 is a large ballistic missile early warning radar, and there is only one in the entire republic, of course, it is also a great achievement, after it has networked another 110 radars. First of all, it gave an early warning of the early space station of the United States, the "Sky Room". After 8 days of continuous tracking, the early warning system finally made an accurate internal forecast of the fall based on the measured number jù, which was compared with the number jù published by the United States. The discovery time is only 4 minutes away, and the location is only 2.9° longitude and 1.3° latitude

Later, there is a test mission of the Dongfeng 5 missile, and it is a whole tracking number. The farthest tracking distance has reached 15,000 kilometers, and it has reached the border of South America. These are all missile defense systems that the republic successfully built in the seventies, and everything is good. It is definitely equipped only by China, the United States and the Soviet Union.

Britain and France, which are also the P5, are much weaker in comparison, and these two countries have no idea of doing such a project at all.

The Republic has no problem in developing large phased array early warning radars, but this does not mean that the country can develop small phased array radars.

In essence, the 7101 radar is actually made by arranging multiple large unwanted phased array radars together, and a single TR component like an active phased radar realizes the transceiver function, which is not available in this set of radars independently developed by the 14th Institute in the seventies.

In this case, it is necessary to explain the difference between these two types of radar: "No, no, we have an essential difference with the 7101 radar, not that the country can develop the 7101 radar, you can successfully develop the early warning aircraft airborne radar, we need miniaturization, the need for active phased array, this thing we have consulted the most experienced 14 in China, they said that they can not get the qualified high-power TR components that can be used by the early warning aircraft, In other words, we can't even solve the most basic radar components now! ”

This time I understood the situation, and even the Air Force was a little confused: "That is to say, it is impossible to get qualified high-power TR components in China in a short period of time, and if there is no such thing, the airborne radar used on the AWACS aircraft will not be able to carry out basic research and development work at all, right?" ”

After the Air Force spoke, the Army remembered something, and interjected again: "We had a Type 373 gun position reconnaissance and school-firing phased array radar project, which was equipped with the PLZ-45 self-propelled artillery system being developed, and the same active phased array radar system was used, and the news given by the 14th Institute now says that there is no problem with the research and development of the radar, and it also says that the TR component has been manufactured." ”

As for the reconnaissance radar used by the artillery, the TR component used on it wants to be used in the early warning radar, which makes Chief Master Wang helpless at the same time, and he can only explain it patiently.

"We also know this radar, but as I just said, this is an artillery reconnaissance radar, and the farthest distance will not exceed 50km, which does not require much power from the TR component. However, our early warning aircraft requires at least 500km to the sea, 450km to large high-altitude targets, 300km to medium-sized targets, and 260km to small low-altitude targets when cruising at an altitude of 10,000 meters. ”

Chief Master Wang tried his best to keep it simple, but this time most of the people could understand it, and only after understanding the situation could these leaders understand how difficult it would be for the early warning aircraft to take the active phased array plan this time.

The Air Force, which understood the situation, began to struggle for the first time, this thing needs to be developed from the most basic components, and if it is to wait, the time for the successful development of the AWACS aircraft will be in the double digits in the end.

Although the Air Force has time, it is not such a waiting method!

"Well, we kind of understand some of the situation, that is, we want to develop an AWACS aircraft that is more advanced than the E-3, and we need to start with the most basic phased array TR components, and only in this way can we be a generation ahead of the American AWACS aircraft, right?"

To be ahead of the American early warning aircraft generation, for the self-made early warning aircraft industry of the republic, Yang Hui said that there is a lot of pressure: "It can indeed be said that way. But as long as we can break through the phased array radar used on the AWACS aircraft and then use the same TR component, we can develop an active phased radar on board a fighter aircraft, and even our Navy's own Aegis system. The TR components required for these radars are all about the same in power. ”

After finishing speaking, Chief Engineer Wang suddenly remembered something, and then added a sentence: "If we insist on using the TR component on the 373 artillery radar to make an early warning aircraft radar, I can give an example: For example, the F-2 fighter that Japan is now developing, according to intelligence, the TR component of this radar is about the same as the 373 artillery radar in terms of power, although it is a large-caliber active phased array radar, but their theoretical detection range, That is, it is absolutely impossible for conventional targets such as fighters to exceed 80km, and such an active phased array radar is even much inferior to the caliber flat slit radar.
