Chapter 1086 The terrifying interception ability of the shield ship
The red team's Z-18F anti-submarine helicopter is rushing to the sea where abnormal radio waves have been detected to prepare for a submarine search.
However, just as they were flying towards the target sea area, the pilot on board suddenly saw a line of white smoke extending towards the aircraft carrier formation on the distant sea surface in the thin morning light.
In fact, the speed of the submarine-launched Harpoon anti-ship missile is not very fast. Before entering the end, the flight speed is only Mach 0.85.
Therefore, under the condition of long-distance visual inspection, the anti-submarine helicopter pilot almost watched a few lines of white smoke extending all the way, flying close to the sea from the sea under the belly of his aircraft, in the direction of the formation's position.
"An incoming anti-ship missile was detected! Direction 122, distance 82 kilometers!"
As soon as he finished speaking, the pilot saw not one, but many anti-ship missiles rushing toward the formation.
Even not far away from the left and right sides of my anti-submarine helicopter, I can vaguely see the traces left by the anti-ship missiles flying by.
He could almost conclude that there was more than one Huang Fang submarine nearby.
He can almost conclude that it must be the Soryu-class submarine with the most common equipment in the opponent's submarine team.
Therefore, he immediately reported the situation to the formation command room and requested that additional anti-submarine helicopters be dispatched to the area for anti-submarine support.
After all, if he has only one helicopter to search for multiple submarine targets, it will take too long, and the other party may take the opportunity to escape.
Almost at the same time that the Z-18 anti-submarine helicopter visually discovered the Harpoon anti-ship missile, the air defense interception and detection network in the No. 001 aircraft carrier formation had already issued an alarm.
The two 052D ships located on the right side of the formation are equipped with the 346A active phased array radar. Its performance exceeds the AN/SPY-1A radar of the "Ticonderoga-class" cruiser and is not inferior to the "Burke"
Air defense radar system installed on II" class ships.
In addition, there was a Z-18 early warning aircraft patrolling in the sky at this time, and the 346A quickly captured the incoming target.
one……
two……
three...
four...
A total of 18 targets rushed towards the formation.
The operators in the formation control room were not panicked at all.
Because the 052D destroyer is not only equipped with the domestic 346A phased array radar, but also the 366 multi-band over-the-horizon radar. This combination greatly increases the impact of the earth's curvature on the 052D detection range.
Because radar's sea detection is a straight-line transmission type, affected by the curvature of the earth, the detection distance is generally a conventional line of sight.
As the saying goes, you can see far when you stand high. The best way to increase the sea detection distance is to raise the radar. However, due to the larger size and heavier weight of the phased array radar, the erection height has a greater impact on the center of gravity of the ship.
, a balance must be struck between the erection height and the stability of the ship, so its sea detection range is limited.
The role of the Type 366 multi-band over-the-horizon radar is a means to enhance the detection range, which can effectively solve the detection problem of low-altitude sea-skimming targets and extend the over-the-horizon detection range to more than 100 kilometers or even hundreds of kilometers, which is enough to make up for the loss.
Defects of the 346/A radar.
Whoosh!
Whoosh!
Whoosh!
Through the command distribution of the formation data link, the two 052D destroyers on the right opened the front launch system manhole cover and continuously fired interceptor missiles outward.
In fact, from the perspective of the red team's carrier formation, these 18 Harpoon anti-ship missiles are nothing to fear.
The only thing you need to be careful about is the close distance.
It can be seen that this is a submarine formation that Huang Fang has been ambushing nearby for a long time. It was not temporarily dispatched here, otherwise the fleet's anti-submarine helicopters would not have discovered it.
The anti-aircraft missile launched by 052D at this time is HHQ-9B. Its vertical launch system carries 64 HHQ-9B, 16 anti-ship missiles (range 400~1000 kilometers) and cruise missiles (range 2000 kilometers), in addition to rockets
Boost torpedoes, etc. It can also be seen from this configuration that the 052D is rightly called the strongest air defense ship.
Therefore, the formation did not panic at all.
Not to mention two 052Ds can be dealt with at the same time, one is enough to deal with it.
What's more, don't worry even if something slips through the interception of HHQ-9B, short-range air defense also has a set of 24 HHQ-10 close-in defense interceptors to provide near-air interception.
Taking a step back, if both HHQ-9B and HHQ-10 are lost, there are two 1130 close-in defense systems at the bow and stern, which are the last defense force of the 052D destroyer.
The 1130 close-in defense system has 11 gun barrels. It adopts a double-drum ammunition chain-free ammunition supply mode. The barrel rotation is driven by an independent power supply and is fired by an electric spark. It uses 30mm discarding sabot and stabilized wing armor-piercing projectiles. The effective range against missile targets is 3,000 meters.
The plane is 3500 meters away.
1130 can use radar, optical, infrared and other tracking systems to lock targets. It can track 30 targets at a time and respond according to the degree of threat. That is to say, after turning on the fire control radar, 1130 will enter the duty state. Once the target breaks into
With its interception range, 1130 will fire immediately.
This kind of close-in defense artillery covers the direction of the incoming missile with a dense barrage, ensuring that one or two shells hit the incoming missile to achieve the goal of destroying the incoming missile. The interception probability for subsonic targets is 90%, and the interception probability for supersonic targets is 90%.
It is 70%. The faster the speed, the lower the probability of interception. For example, a target speed of 5 times the speed of sound is 1.5 kilometers/second, and the effective range of 3000 meters only has a reaction time of 2 seconds.
As a result, the anti-missile interception system on the 052D has a probability of intercepting supersonic anti-ship missiles of more than 99%, let alone subsonic anti-ship missiles such as Harpoon. The only powerful thing about Harpoon is the end
At some point, the trajectory will change. First there will be an upward surge, and then there will be a dive for initiation.
Since the interception distance this time was nearly 100 kilometers, the formation had plenty of time to react, so there was no pressure at all.

Huge fireballs exploded on the sea more than 40 kilometers away from the formation.
Since the distance did not reach the range of a close attack, the Harpoon anti-ship missiles had no time to enter the terminal change orbit, and were all hit by the HHQ-9B fired at high speed and successfully intercepted. They could only turn into fragments and splash into the sea.
The 052D has proven itself to be one of the top destroyers in the world with its own strength.
Inside the No. 1 Soryu-class submarine, the captain was heartbroken.
All anti-ship missiles have been intercepted.
This is only two 052D destroyers involved in the interception.
It seems that it is simply impossible to rely on submarine-launched Harpoon anti-ship missiles to evade the air defense interception network composed of destroyers in the aircraft carrier formation at a distance of one hundred kilometers.
The only chance is to get within 50 kilometers.
Unfortunately, there is no such opportunity anymore.
At this time, he had to face a fatal problem - escape, or fight to the death and reload again, and then launch a second round of attacks.
Loading takes a lot of time.
Even if the communication is cut off again and lurks under the sea to enter the "Teenage Mutant Ninja Turtles" mode, although the red side's anti-submarine system will lose its own acoustic and radio signals for a short period of time, the red side has roughly determined its position, and the anti-submarine helicopter can easily
We will reach this sea area soon.
He can almost tell that the red side will not send an anti-submarine helicopter here, but will send several helicopters to drop sonar buoys into the sea using a dragnet-style search method. The sound of this thing is one-time, a bit like fishing.
A buoy is used. It floats on the water, the lower half is sunk into the water to install a listening device, and the upper half is equipped with an antenna. Drop a buoy at a certain distance in the sea area where submarines are infested, and use the sound received by the listening device to determine whether there is a buoy.
After the submarine finds the buoy with the loudest sound, it puts down its sonar to detect and analyze the submarine's specific position parameters, and then drops a torpedo to attack.
Once several helicopters begin to carry out distributed releases and seal off an entire sea area, their three submarines may be doomed.
After hesitating for 10 seconds, Captain No. 1 finally chose to give up the second round of attack.
"Immediately evacuate in the direction of the wave base, reduce the speed to 4 knots in silent mode, go east first, leave the shallow water area and then turn back! From now on, cut off communications and remain silent!"
After issuing some instructions, he ordered the submarine to enter silent mode, and the submarine began to turn east towards TPY and began to leave the battlefield at a speed of 4 knots per hour.
