Chapter 1185 Something flew past
Earlier in the day.
Bohai Sea coast.
In a 54K6 combat command module, Colonel Lu Zhicheng from the Air Force Ground Guidance Force of the Quancheng Military Region was staring at the circular radar screen in front of him while looking at the electronic clock next to him from time to time.
The surface-to-air missile regiment he commanded moved here from its original station about 200 kilometers away as early as a week ago, and deployed an air defense battalion position with a strengthened regiment-level command system.
Generally speaking, this should be regarded as the standard start of a practical training, and it should be followed by a round of confrontation exercises or shooting training based on "unknown airspace conditions and complex electromagnetic environment".
But this time, after the troops were maneuvered into place, they were put on standby and did not receive any new instructions for several days.
It was not until the evening of the previous day that the regiment command post officially received an order from their superiors, requiring them to serve as defenders and simulate a confrontation with a "small high-speed ballistic target."
Captain Lu, who once participated in the S300PMU2 delivery test in Suzhou, knows that this statement is generally equivalent to a short-range ballistic missile.
Therefore, they have been in a state of combat readiness since early this morning, always waiting for the appearance of the incoming target.
At this time, the regiment chief of staff Li Jixiang, who was sitting two positions away, suddenly turned around and reported:
"Regiment commander, I have received a notification from the military air force that the target bomb is expected to be launched near 0847 hours!"
As his voice fell, the spirits of everyone in the command cabin suddenly lifted, and the atmosphere became serious.
As for anti-missile interception, all countries are generally still in the preliminary exploration stage, so they will adopt a clear chess approach in most tests.
That is, the interceptor will obtain the general time and direction of the target's attack in advance.
It is equivalent to a small penetration but not a penetration.
For example, when the US military tests to intercept intercontinental ballistic missiles, it even inputs all the ballistic data of the target missile into the anti-missile system in advance.
Otherwise, many confrontations may not even be possible.
Lu Zhicheng took a deep breath and approached the microphone installed on the command podium:
"The whole battalion is first! Turn on the radar radiation and search for the target!"
The air defense position was still quiet on the surface, but the personnel in each fighting position entered the combat state in an orderly manner like clockwork.
After Lu Zhicheng hesitated for a moment, he issued a second, more specific instruction:
“Adjust the 96L6E2 radar to the L-band to share the fire control radar’s illumination. pressure, and at the same time, the 64N6E radar fully took over the warning mission..."
"..."
In the test last year, the live-fire firing session included shooting down two different types of short-range ballistic missiles .
Therefore, even though he has just changed equipment for more than a year, he has already learned some tricks for intercepting ballistic targets.
However, even so, the actual interception efficiency is still cautiously optimistic -
The problem is not with the radar, but with the missile.
Missiles designed for aerodynamic targets often focus more on dynamic range and lack sufficient initial acceleration. Even if the radar has formed stable tracking, there is still a high probability that the interceptor will miss the incoming target because the interceptor has no time to maneuver.
“Commander, do you need to double the number of fire channels to intercept?”
Chief of Staff Li Jixiang, who was planning interception firepower in the command system, suddenly asked.
Lu Zhicheng was stunned at first, and then shook his head in confusion:
"What kind of fire channel should be added? There is no live ammunition shooting session at all today..."
"From the report Judging from the launch position, the target missile is most likely to be a short-range ballistic missile... According to my experience, it is relatively easy to capture and track such operational and tactical ballistic targets under the unified management of the theater system command post. ”
The S300P, which is used for ground air defense, did not have anti-missile functions planned from the beginning of the design like the S300V. However, the 83M6 command center at the regiment level has specifically optimized its ability to intercept high-altitude ballistic targets. .
This means that during virtual confrontations where missiles are not launched, they can usually take advantage.
However, after finally finding a chance for confrontation, a large regiment command post cannot just wait for the target to attack.
Therefore, a few seconds later, Commander Lu looked at his chief of staff again:
"Old Li, please take some new staff officers for map-plotting training. Simulate the situation where the early warning radar is destroyed or loses contact..."
Although new military technology has introduced confrontation into the information age, for soldiers, traditional paper work is still conservative but reliable choose.
And Li Jixiang happens to be a leader in this area.
"Yes!"
The chief of staff immediately stood up, picked up the black, blue and red pens from the side, and came to the tactical table not far behind him.
Two other relatively young staff officers also came over, ready to appreciate the unique skills displayed by their leaders...
"Report, according to ballistic calculations, the target is about to enter the interception range!"
The voice of the 64N6E radar operator came over the radio.
At the same time, the search results of the battlefield management radar were also displayed on the screen in front of Lu Zhicheng.
As if the words were followed, just a few seconds later, a dazzling echo appeared near the center of the radar detection range - 34km away, 47.7km altitude
"The target has appeared, prepare to track it!"
While giving the command, Lu Zhicheng also rotated the trackball in his hand to keep the target within the optimal search range of the radar.
At the same time, Li Jixiang also drew the first blue mark on the paper.
The search frequency and accuracy of the battlefield management radar are relatively limited, so according to the conventional process, the general information captured will be shared with the 96L6E2 and 30N6E radars, which will quickly scan the target area multiple times, and then scan the target area The firing unit provides more precise fire control parameters.
The altitude of 47km is equivalent to a reaction time of about 38-40 seconds for common short- and medium-range ballistic missiles.
Enough.
According to the rules of the simulation exercise, as long as the target interception information is successfully sent to the launch unit and the launch squad leader presses the firing button, the interceptor can be counted as the winner.
The experienced Lu Zhicheng has even moved his fingers to the button for transmitting accusation information in advance.
However, it was different from what he expected.
The feedback from the fire control radar unit has not yet sounded on the radio.
On the screen next to it, only a few intermittent trajectory points flashed past, and there was no stable and clear target trajectory as usual.
“What’s going on?”
Watching the interception countdown in the lower right corner of the screen gradually return to zero, Lu Zhicheng suddenly started to sweat.
“The target speed is too fast, and the small-angle scan cannot keep up with the vertical area changes.”
The slightly urgent voice of the radar company commander sounded in my ears:
"We are re-confirming the scan range..."
"..."
As one of the first units to be equipped with this type of air defense system, Lu Zhicheng's men moved very quickly and completed an interception-transmission-tracking process again in a short period of time.
However, the target in the sky seems to be faster.
When the command center shared the target information with the fire control radar for the second time about 10 seconds later, the altitude information displayed on the screen had actually changed to 23.3km.
Lu Zhicheng almost made his eyes pop out.
More than 2km per second? ? ?
This is obviously not the terminal speed that a normal short-range missile should have.
Even many old-fashioned medium-range missiles may not be able to reach it...
"Retry tracking!"
Despite being unprepared for this in advance, this elite team The ground guidance troops still exerted their subjective initiative to the extreme.
By rubbing the sparks out of the keyboard, the 96L6E2 radar finally intercepted a stable signal below an altitude of 10km before the missile finally hit the target.
However, before Lu Zhicheng even had time to move his fingers, the target disappeared from the search range again because the height was too low.
Obviously, this has hit the predetermined area.
Their interception failed.
Only one successful speed measurement data remained on the screen -
2250m/s.
About 6.6 times the speed of sound.
For comparison, the 48N6E2 air defense missile of the S300PMU2 system can reach a speed of approximately 1750m/s at the end of the power stage.
According to general theory, it is best to keep the speed of the interceptor missile at more than 1.5 times that of the intercepted object in order to better deal with the target...
For a time, in the entire command cabin, All that's left is the whine of the cooling system running.
Lu Zhicheng stared straight at the radar screen in front of him, as if he wanted to see something from it.
Li Jixiang, who was in charge of manual plotting, had one hand hanging in the air and didn't even have time to place the second marking point.
The two young staff officers who had just graduated from the military academy had not yet realized what had happened.
He looked at the chief of staff for a while, and then looked at the regimental commander for a while.
"Just now...it seemed like something flew by?"
