China’s new ship-borne hypersonic missile unveiled?
Some time ago, the YJ-21 missile, which has always been shrouded in mystery, was finally revealed!
From the published video footage, the footage of the YJ-21 being launched from the 055 destroyer not only unveiled the mystery of the YJ-21, also confirmed that the 055 destroyer did not use the CM-401 missile..
According to the speculation of many scholars, the combat method of the YJ-21 anti-ship missile is the same as that of the Dongfeng 21D. They are both vertical attack anti-ship ballistic missiles . However, in order to adapt to the needs of the ship, the YJ-21 can also be said to be a "shrunken version" of the Dongfeng 21 missile. The size of the missile body is much smaller.
The mainstream anti-ship missile equipped by the United States is mainly AGM-84, which is the Harpoon missile . Its early version is in use and has entered the terminal attack stage. simply uses inertial guidance and is equipped with a 220 kg Warhead.
requires higher strike accuracy in actual combat to improve the damage effect. In the iterative version, adds GPS and two-way data links to improve the damage effect . It's one thing to hit
accurately, but it's another thing to hit it well enough. The AGM-84 anti-ship missile has enhanced guidance capabilities in the later period, but its range is really pitiful, only more than 200 kilometers, and the attack range of is relatively limited .
The second is its penetration capability. As a subsonic missile, the AGM-84 anti-ship missile itself has a flight speed of only Mach 0.8. This is easy for the anti-missile system to intercept. can even intercept it. Even the ship's last line of defense, the and rapid-fire cannons, are easily intercepted successfully.
In comparison, the speed of the Eagle Strike 21 in the terminal attack stage can reach Mach 10, which is equivalent to 10 times the speed of sound. The speed of sound propagating in the air is 340 meters per second, 10 times the speed of sound, that is, the speed of the Eagle Strike 21 can reach 3400 meters per second when it finally hits the enemy.
Even if it is hit directly at such a terrifying speed without an explosion, it will still cause a fatal blow to the enemy ship.
According to foreign media speculation, the yield of the YJ-21 warhead will reach an astonishing 800 to 1,000 kilograms. Combined with the impact generated during the fall, the impact on most ships will be devastating..
On the other hand, according to the principle of the anti-missile system, the interception of missile is also carried out from the three stages of missile launch. is mainly focused on the mid-stage interception and terminal interception .
When the missile is launched, the radar of the anti-missile system will lock to the position of the missile, analyze the trajectory by intercepting the missile's flight trajectory, and then intercept it. For ordinary subsonic anti-ship missiles, terminal interception is enough to deal with it, but it faces For ballistic missiles that fly at several times the speed of sound, interception during terminal attacks is very difficult. The current anti-missile system can only "try luck" through quantity.
The interception of ballistic missiles can basically only rely on mid-course interception, but most ships do not have mid-course interception capabilities. This also leads to the fact that the YJ-21, whose terminal attack speed reaches Mach 10, can basically evade almost most of them. The anti-missile system intercepts .
As an anti-ship missile, another highlight of the YJ-21 is its range. Its range directly reaches 1,500 kilometers, which can be said to be almost the "ceiling" of the current anti-ship missile range. In comparison, the AGM-158C long-range anti-ship missile with the longest range in the United States is only 550 kilometers.
Therefore, after the suspected image of the Eagle Strike 21 appeared, it immediately aroused widespread heated discussion, because this is definitely an absolute killer weapon to shock and attack the enemy, and the long-range anti-ship missile is also a major weakness of the United States, Eagle The emergence of Attack 21 is definitely a huge threat to the United States.
一
Eagle Strike 21 is equipped with a hypersonic gliding warhead?
According to the launch photos of the Eagle Strike 21 disclosed by foreign media, its missile body and warhead are almost the same length, and there are several tail fins at the end of the warhead, indicating that it has the ability to maneuver the orbit twice during the loading stage, which can be greatly enhanced Penetration capability. And its long and narrow warhead is not only reminiscent of the gliding warhead of the same model as Dongfeng 17?
Speaking of Dongfeng 17, we have to mention its hypersonic waverider warhead. Different from ordinary ballistic missile warheads, the waverider warhead can change orbit in the middle of the flight, and even directly bypass the enemy's radar monitoring area. The orbit changes that ordinary ballistic missile warheads can perform are only fine-tuning for accurate guidance. does not have the ability to significantly change orbits .
Therefore, when the enemy intercepts the mid-course missile, the unpredictable "snake-skin movement" and extremely fast speed of the waverider warhead make it impossible to calculate the flight trajectory. even has no way to monitor !
If the Eagle Strike 21 uses the same waverider warhead as the Dongfeng 17, it will greatly enhance its penetration capabilities.
However, according to the information disclosed by the "Dynamics" website, the appearance of the Eagle Strike 21 should be closer to China's export-type anti-ship missile CM-401. The CM-401 missile was developed by China Aerospace Science and Industry Corporation. According to missile export control restrictions, the maximum range is designed to be 290 kilometers..
The missile's appearance is relatively close to Russia's Iskander missile , and its biggest advantage is that it can fly at supersonic speeds .
二
"Star equipment" coordinated operations
To win the war, it is definitely not possible to just rely on one star weapon. The key is to establish a three-dimensional and all-round combat system.
For example, the attack on the surface ship force is by no means relying solely on surface forces to fight, but the navy, air force, and rocket force jointly establish a joint combat system. The navy acts as the leading force in direct confrontation, the rocket force provides follow-up fire support, and the air force As an anti-air strike force, thus forms a three-dimensional and comprehensive strike force .
Everyone must be familiar with the aircraft carrier killer Dongfeng 21D. In addition, Dongfeng 26 is also a great weapon for land-based platforms to attack aircraft carriers, but ship-based missiles have always been vacant in their attack power against aircraft carrier battle groups .
It was not until the emergence of the Eagle Strike 21 that this gap was filled, but there is another "star equipment" that is very eye-catching, that is the 055 destroyer equipped with the Eagle Strike 21. The combination of the
055 destroyer and the Eagle 21 "star equipment" even led foreign media to believe that the 055 destroyer would be the world's most powerful destroyer.
I believe that everyone will be a little confused that the 055 destroyer can be called the world's most powerful destroyer. First of all, the YJ-21 is already at the forefront of anti-ship missiles, and then the 055 destroyer has as many as 112 vertical launch units .
Not counting other ship-borne weapons, the YJ-21,055 destroyer alone can carry dozens of them. Even if the opponent has mid-course interception capabilities, facing so many YJ-21 attacks no matter how strong the opponent's interception capabilities are, there will be "slips through the net" fish” .
In addition to this pair of "star equipment" combinations, the Eagle 21 may also develop an air-launched model in the future to cooperate with the H-6K bomber.
Prior to this, the main anti-ship weapon partner of the H-6K was the Eagle Strike 12 missile .
As an anti-ship missile, the Eagle Strike 12 has a strong penetration capability, and its terminal attack speed can reach Mach 4. However, its range is only 400 kilometers, which makes the H-6K difficult to carry out anti-ship missions. Threatened by enemy air defense forces.
and the YJ-21 just combine the advantages of both, and the combat radius of the US aircraft carrier-based aircraft has long been left behind by the H-6 plus YJ-21.
Coupled with a series of road-based medium and long-range ballistic missiles such as Dongfeng 21 and Dongfeng 26, has formed a land-based, air-based, and sea-based multi-dimensional three-dimensional strike combat system !
三
Why is the Eagle Strike 21 a true aircraft carrier killer?
Know yourself and the enemy, and you will never be defeated in a hundred battles. If you want to know how to become an "aircraft carrier killer", you must know the combat mode and system of aircraft carrier battle group , so that you can be targeted!
Regarding the aircraft carrier strike weapon system, in fact, the one that everyone is most familiar with should be the medium and long-range ballistic missile of the Dongfeng family - Dongfeng 26!
Dongfeng 26 is nicknamed " Guam killer" by netizens because of its range of nearly 4,500 kilometers. It is also called "Guam Express", and Dongfeng Express has always adhered to the principle of "once sent, it will not be rejected" , and according to official reports, can launch without support under field conditions.
In contrast, other types of missiles often need to establish a flat position, and the missile can be ready for launch only after testing and leveling. Therefore, the launch of many missiles is limited by the number of positions constructed.
The more positions are built, the greater the possibility of being detected by the enemy . In war, they will face the risk of being locked in advance, resulting in the missile not being launched, but the enemy's firepower has already arrived.
Dongfeng 26 can stand by for a long time without any support, which greatly reduces the dependence on the location, which also creates the effect of "coming and going without a trace" .
So, what strike capabilities does the aircraft carrier battle group have?
First of all, an aircraft carrier battle group is generally equipped with aircraft carriers , cruisers , destroyers, frigates , submarines and supply ships . The number of equipment for each ship type is slightly different depending on the purpose of combat.
Then there are various carrier-based aircraft , which is also the core of the aircraft carrier battle group and serves as the main strike force.
Take the US aircraft carrier as an example. It usually carries more than 50 fighter jets , 4-6 early warning aircraft and a dozen other types of aircraft.
The aircraft carrier is the core force of the aircraft carrier battle group, all other ships are basically responsible for both strike missions and the escort of the aircraft carrier.
When performing combat missions, the submarine formation serves as the vanguard, clearing out any enemy submarines that may appear ahead at a distance of about 100 nautical miles from the aircraft carrier. Other surface combat ships are responsible for air defense, anti-submarine and other defense tasks, and protect the aircraft carrier located in the center of the formation.
As a take-off platform for aircraft on the sea, aircraft carriers have relatively high take-off and landing efficiency.
Whether it is traditional ejection take-off or electromagnetic ejection take-off, four aircraft can be taken off at one time. Generally, the aircraft dispatched are in formation , so four other aircraft can be ejected in a very short time.
Therefore, when dealing with a medium-sized country, one or two aircraft carrier battle groups are completely sufficient. How to counter aircraft carrier battle groups has always been a very difficult problem.
In the face of such a powerful combat power, it is completely unfeasible to rely solely on a single weapon and equipment or a single military branch.
It can be seen from the deployment of the YJ-21 that not only the 055 destroyer is equipped with the YJ-21 anti-ship missile, but in the future, the YJ-21 will also be equipped with the YJ-21, the aircraft carrier killer.
Whether it is Dongfeng 21D or Dongfeng 26, these famous anti-ship ballistic missiles are land-based missiles with limited combat range. The deployment of the sea-based YJ-21 anti-ship missile, coupled with the YJ-21 carried on the space-based platform, has truly formed an all-round three-dimensional "anti-access and area denial" capability.
This also makes people think, how many "aircraft carrier killers" are needed to build the strike force of the aircraft carrier battle group?
First of all, we should start from accelerating the development of new equipment, continuously improve the combat capabilities of individual weapons and equipment, and then continue to increase the number of equipment. The most important thing is the development of the ability to coordinate and cooperate with various strike forces..
