Under normal circumstances, after completing one round of firing, the air defense forces should immediately adjust the firing elements according to the actual situation and prepare for the second round of firing, or quickly return to a concealed state.

However, most of these lessons have been passed down decades ago.

The last time anti-aircraft artillery played a large-scale role was in the Vietnam War.

The tactics used were not fundamentally different from those of World War II.

But now that it's the turn of the century, it makes sense to set up an ambush in concealment before engaging the enemy, but to think about regaining concealment after a round of fire is completely deceiving yourself.

What's more, this is a training mission.

It means that the nature is closer to the "verification of tactics".

The 6 Brigade of the Air Defense received a request to record in detail all command parameters after each round of firing.

In order to compare the trajectory and hit situation with the radar on the other side afterwards.

After completing the first round of shooting, Zhu Xuejun leaned out and raised his binoculars to try to observe his "results" while commanding the staff officers to record the data.

After all, even anti-aircraft artillery has basically achieved radar fire control over the years, and it is completely possible to see the target on the screen throughout the whole process.

Nowadays, I am still a little unaccustomed to losing this intuitive means at first glance.

However, Zhu Xuejun could only see through the telescope the night sky as deep as splashing ink, and the faint smoke and dust that had just been blown off by the cannonballs that had just been fired.

After all, the target aircraft is only a target the size of an anti-ship missile, and at an altitude of 6,000 meters or at night, it is normal to see it and ...... it normally.

Fortunately, just when he felt a little pity, the voice of the command center came from the radio station:

"Yinshan 01, Yangshan Station reported that your artillery fire accurately covered the airspace around the target, and the target has been shot down."

"Note that Target 02 is preparing for takeoff and is expected to enter the test airspace in 15 minutes at an azimuth of 180 ......"

“……”

Almost at the same time, about a hundred kilometers away.

The Northern Air Defense Command Center of the Beijing Military District.

A group of mid- and high-ranking officers were staring at the radar information displayed on two large screens in front of them.

On the radar map on the right of it, it is clearly shown that one of the targets has been split in two and is falling at a high altitude.

It was the target aircraft that had just been damaged by anti-aircraft fire, which eventually led to the disintegration and crash.

It's a pity that because of the problem of the rate of information update, it is impossible to show the process of hitting the target with artillery fire.

And, when the data refreshes again after half a minute, the screen is clean again.

This means that the two pieces of wreckage have fallen to an altitude where the curvature of the Earth does not allow radar to see.

In the whole process, the other screen on the left did not show any valuable information.

Only when the anti-aircraft artillery fire exploded in a large area between 5900 and 6200 meters, it showed a huge reflected signal.

That's a radar echo from a large number of metal fragments.

"Yongjin, it seems that this idea of using early warning radar to provide general directions and then using anti-aircraft artillery fire to provide rough coverage still has a certain degree of feasibility......

Fu Quanyou, who was sitting in the middle of the first row, turned around and said to a lieutenant general wearing an air force uniform next to him.

"Hmm...... I have to say that in terms of the effect of the blow alone, it is even better than we expected before. ”

Li Yongjin nodded, but his eyes still did not take his eyes off the two screens in front of him.

After a slight pause, the conversation changed again:

"It's a pity that we can't really simulate the target characteristics of the stealth aircraft now, this target aircraft modified with anti-ship missiles, although it is already the smallest model of the RCS, but compared with the target we expect to face, it is still a lot larger."

"I don't know if on the real battlefield can detect the target signal in advance so smoothly."

As the commander of the Air Force of the Beijing Military Region, he actually presided over the process of translating the ideas put forward by Chang Haonan into concrete tactics.

Naturally, this training mission is also underway.

From receiving instructions to making a plan, the entire process took less than 100 hours.

And tonight, it is equivalent to a big test for him.

The two screens in front of the people correspond to two sets of radar data.

On the right, there is a set of long-range early warning radars that have been improved by passive mode, which were originally used by 14 for technical testing, but now they have been moved over to exert their residual heat.

On the left, there is a common set of SNR-75E, that is, the fire control radar of the Hongqi-2 surface-to-air missile.

In order to avoid interference, the two are deployed in different directions, but they are also about 45 kilometers away from the test airspace.

It's a bit close for China, but just right for the Balkan environment.

The test results are also similar to the previous estimates -

When faced with a target with a small radar reflection area, the guidance radar in the S-band cannot effectively see the target at all.

The improved passive positioning radar can capture the signal continuously and stably.

This at least testifies to the potential of the latter in terms of anti-stealth.

"You can also think about the bright side."

Compared with Li Yongjin, who passed the exam but was still worried, Fu Quanyou's mentality was much better:

"The passive radar we used for testing is only an improvement on the basis of the 407 radar, and it is already an old guy from more than 30 years ago."

"On the side we want to support, although the opponent is a stealth aircraft with a smaller radar reflection area, they are also better equipped in their hands."

"The specific plan proposed by the technicians is to improve the two Soviet-made P18 early warning radars, so that this time and again, it is equivalent to the spear and shield have been strengthened, and I think there is still something to fight."

If you say that after getting Ding Gaoheng's assurance, his mentality is still "betting".

After seeing the test results tonight, the mentality has basically become "stable".

Because even if this transnational support operation itself fails to achieve results, as long as you can "see" the stealth aircraft, you will not lose money.

"That's right."

Seeing that the leaders had made such a positive statement, Li Yongjin naturally relaxed a lot:

"Anyway, no matter what, this idea of replacing a single giant radar with multiple passive radars and doing multi-point detection of stealth targets is definitely promising."

"One of the most troublesome in this new three-fight three-defense is finally a bit eyebrow-raising......"

The "most headache" in his mouth naturally refers to the stealth planes in the new three dozen.

In the past few years, although the Air Force has also put forward a lot of relevant ideas, in practice, it is often directly stuck in the first step, that is, "realizing that there is a stealth target attacking".

Now it's time to at least start thinking about the second step.

"That's right, Yongjin."

After a period of silence, Fu Quanyou suddenly spoke again:

"Judging from the current situation, do you think it is necessary to further retain a few large-caliber antiaircraft artillery units in the establishment of the air defense forces for the defense around key cities?"

Hearing this question, Li Yongjin immediately felt a little numb on his scalp-

It is very likely that he will be promoted to the leadership of the Air Force in the next step, and if he takes office, the equipment of the air defense forces will not be modernized, but will be equipped with a bunch of old anti-aircraft guns......

Then his name can basically be engraved on the pillar of shame of the military branch.

Thinking of this, Li Yongjin hurriedly shook his head:

"After all, the range of anti-aircraft artillery is still too short, and it can only be used as a supplementary air defense after the opponent completes the attack, and its own safety cannot be guaranteed, which is basically equivalent to exchanging a position for an aircraft on the opposite side."

"In the short term, it is okay to use it for emergency response, but in the long term, more advanced long-range anti-aircraft missiles are still needed......"

Fortunately, Fu Quanyou just asked casually, and he didn't really have the idea of expanding the mixed air defense brigade into an anti-aircraft artillery division, so he didn't continue to dwell on this issue......

……

While the two were chatting, the next few rounds of testing were completed one after another.

Basically, as long as the target does not make too drastic changes in the flight altitude, then the accuracy of artillery fire coverage can reach more than 90%.

Although two of the most fortunate targets crossed the test airspace unscathed, it was because they were physically too small to avoid the flying fragments.

And a stealth aircraft, no matter how small the RCS is, the size is always the size of a normal aircraft.

There's no reason to run away.

Watching the last target on the radar display disappear in a field of artillery fire, Fu Quanyou took a deep breath, stood up on the ground, and gave an order in an orderly manner:

"Yongjin, you send a helicopter to the position of the mixed 6th Brigade as fast as possible, and bring back the shooting command data they recorded."

"Also, let the comrades of the Electric Technology Group make a copy of the radar signal data, and I will also bring it back......"

"Organize a group of commanders and staff officers with experience in commanding antiaircraft artillery to compile the test data into a tabulated ......"

"Yes!"

Li Yongjin saluted, then turned around and prepared to leave the command hall.

"Wait a minute!"

Fu Quanyou stopped him from behind again:

"Remember to find another batch of translators and translate all the text into ......"

Speaking of which, he hesitated slightly:

"Let's settle on Russian and Serbo-Croatian for the time being, so that they can both understand and have a more reasonable hint of the source."

"In short, in any case, Chinese must not appear in these materials, and when it comes to numbers and tables, it must not appear in China's unique writing habits."

Li Yongjin immediately understood what his superiors meant, and raised his hand again to salute:

"Yes!"
