Chapter 670 No Chinese allowed!
Under normal circumstances, after completing one round of shooting, the air defense force should immediately adjust the shooting elements according to the actual situation to prepare for the second round of shooting, or quickly return to concealment.
However, these experiences were basically passed down decades ago.
The last time anti-aircraft artillery was used on a large scale was in the Vietnam War.
The tactics used were not fundamentally different from World War II.
But now it is the turn of the century, and it makes sense to set up a concealment and ambush before engaging the enemy, but if you think about regaining concealment after completing a round of firing, you are completely fooling yourself.
What's more, this is a training mission.
It means that the nature is closer to "tactic verification".
The 6th Air Defense Brigade was required to record all command parameters in detail after each round of shooting.
In order to compare it with the trajectory and hit situation detected by the radar on the other side afterwards.
After completing the first round of shooting, Zhu Xuejun, while instructing the staff officers to record the data, leaned out and raised the binoculars to try to observe his "results."
After all, even anti-aircraft artillery has basically achieved radar fire control over the years, and can completely see the target on the screen.
Nowadays, I feel a little uncomfortable losing this intuitive method.
However, Zhu Xuejun could only see through the telescope the night sky as deep as splashed ink, and the faint smoke and dust from the shells that had just been fired could be seen vaguely.
After all, the target drone is just a target the size of an anti-ship missile. It is normal to not see it at 6000 meters high or at night...
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."
"Attention, target 02 is preparing to take off. It is expected to enter the test airspace in 15 minutes, bearing 180..."
"..."
Almost at the same time, about a hundred kilometers away.
Northern Air Defense Command Center of the Beijing Military Region.
A group of mid-level and senior military officers were staring closely at the radar information displayed on the two large screens in front of them.
On the radar map on the right side, it clearly shows that the target just now has been split into two and is falling.
It was the target drone that had just been damaged by anti-aircraft fire and eventually disintegrated and crashed.
Unfortunately, due to the problem of information update rate, it is impossible to show the process of artillery fire hitting the target.
And, when the data was refreshed again half a minute later, the screen was clean again.
This means that the two pieces of debris have fallen to a height that the curvature of the earth does not allow radar to see.
During the entire process, the other screen on the left did not display any valuable information.
Only when the anti-aircraft fire exploded in a large area between 5900-6200 meters just now, a huge reflected signal was displayed on it.
That's the radar echo produced by a large number of metal fragments.
"Yongjin, it seems that this idea of using early warning radar to provide a rough direction and then using anti-aircraft artillery fire to provide rough coverage is still feasible..."
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.
"Well... I have to say that judging from the impact effect alone, it is better than we expected before."
Li Yongjin nodded, but still did not move his eyes away from the two screens in front of him.
After a brief pause, the topic changed again:
"Unfortunately, we still have no way to truly simulate the target characteristics of a stealth aircraft. Although this target drone modified with anti-ship missiles is already the smallest model of RCS, compared with the targets we are expected to face, It’s still much bigger.”
"I wonder if we can detect the target signal in advance so smoothly on a real battlefield."
As the air force commander of the Beijing Military Region, he actually presided over the process of transforming the ideas proposed by Chang Haonan into specific tactics.
This naturally includes the ongoing training mission.
From receiving instructions to making a plan, the entire process took less than 100 hours.
And tonight 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 is a set of long-range early warning radars that have been improved in passive mode. They were originally used by Institute 14 for technical testing, but now they have been moved here to use their remaining heat.
On the left is a common set of SNR-75E, which is the fire control radar of the Hongqi 2 surface-to-air missile.
In order to avoid interference, the two were deployed in different directions, but the distance to the test airspace was still about 45 kilometers.
It's a bit close for China, but just right for the Balkan environment.
The test results are similar to what was previously estimated——
When faced with a target with a small radar reflection area, the S-band guidance radar cannot effectively see the target at all.
The improved passive positioning radar can continuously and stably capture signals.
This at least proves the potential of the latter in anti-stealth.
"You can also think on the bright side."
Compared to Li Yongjin, who was still worried despite passing the exam, Fu Quanyou's mentality was much better:
"The passive radar we used for testing is just an improvement on the 407 radar. It is already an old thing from more than years ago."
"Although the opponents we want to support are stealth aircraft with smaller radar reflection areas, they also have better equipment."
"The specific plan put forward by the technicians is to improve the two Soviet-made P18 early warning radars. This way, it is equivalent to strengthening the spear and shield. I think it is still worth fighting."
If we say that after receiving Ding Gaoheng's guarantee before, his mentality was still "gamble".
After seeing the test results tonight, my mentality has basically become "stable."
Because even if this cross-border support operation itself fails to achieve results, as long as the stealth aircraft can be "seen", it will be profitable.
"makes sense."
Seeing the leaders making such positive statements, Li Yongjin naturally relaxed a lot:
"Anyway, no matter what, this idea of replacing a single giant radar with multiple passive radars to conduct multi-point detection of stealth targets is definitely promising."
"The most troublesome aspect of this new three-on-three defense is finally clear..."
The "most troublesome thing" in his mouth naturally refers to the stealth aircraft among the new three dozen.
In the past few years, although the Air Force has put forward many related ideas, in actual operation, it is often stuck in the first step, which is "realizing that there is an incoming stealth target."
Now you can at least start thinking about step two.
"By the way, Yongjin."
After a period of silence, Fu Quanyou suddenly spoke again:
"Based on the current situation, do you think it is necessary to further retain a few large-caliber anti-aircraft artillery units in the air defense force for defense around key cities?"
Hearing this question, Li Yongjin immediately felt a little numb——
His next step is very likely to be promoted to the leadership of the Air Force. If during his tenure, the air defense force's equipment 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 military branch's pillar of shame.
Thinking of this, Li Yongjin quickly shook his head:
"After all, the range of the anti-aircraft artillery is still too short. It can only provide supplementary air defense after the opponent completes the attack, and its own safety cannot be guaranteed. It is basically equivalent to exchanging one position for one aircraft on the opposite side."
"In the short term, it can be used for emergencies. In the long term, more advanced long-range air defense missiles are still needed..."
Fortunately, Fu Quanyou just asked casually and had no real intention of expanding the mixed air defense brigade into an anti-aircraft artillery division, so he did not continue to struggle with this issue...
……
While the two were chatting, the next few rounds of tests were completed one after another.
Basically, as long as the target does not change too drastically in flight altitude, the accuracy of artillery fire coverage can reach more than 90%.
Although two very lucky target drones passed through the test airspace without any injuries, that was because their physical size was indeed too small and they just avoided the debris flying in the sky.
As for a stealth aircraft, no matter how small the RCS is, the size is still the size of a normal aircraft.
There was no reason to get away.
Watching the last target on the radar screen disappear in a burst of gunfire, Fu Quanyou took a deep breath, stood up, and gave instructions in an orderly manner:
"Yongjin, you send a helicopter to the position of the 6th Mixed Brigade as quickly as possible and bring back the firing command data they recorded."
"Also, let the comrades of the Electronic Technology Group make a copy of the radar signal data, and I will take it back with them..."
"Organize another group of commanders and staff with experience in anti-aircraft artillery command, and compile this test data into a table..."
"Yes!"
Li Yongjin saluted, then turned around and prepared to leave the command hall.
"Wait a moment!"
Fu Quanyou called him from behind again:
"Remember to find another group of translators to translate all the words into..."
Having said this, he hesitated for a moment:
"For the time being, let's settle on Russian and Serbo-Croatian, so that they can both understand it and get a more reasonable hint about the source."
"In short, no matter what, Chinese characters cannot appear in these materials, and when it comes to numbers and tables, my country's unique writing habits must not appear."
Li Yongjin immediately understood what his superior meant and raised his hand to salute again:
"Yes!"
