Dongfeng 21D is an active anti-ship ballistic missile of our Chinese Rocket Army. With a maximum range of more than 2,000 kilometers and a unique instilled anti-ship strike method, Dongfeng 21D has become the most efficient and powerful anti-ship in the world today. One of the missiles. Compared with conventional anti-ship missiles, the Dongfeng 21D has a long range, high accuracy, difficult to intercept, and powerful. It can cause fatal damage to giant warships such as 100,000-ton aircraft carriers. However, these attributes are not the core points of the strong performance of the Dongfeng 21D. The real strength of the Dongfeng 21D is that it is an anti-ship ballistic missile capable of end-of-track maneuvering.
To talk about why the Dongfeng 21D makes the US military a headache and find it difficult to deal with, we must first understand the difference between Dongfeng 21D and conventional anti-ship missiles. Under normal circumstances, the current mainstream anti-ship missiles in the world basically use the ultra-low-altitude penetration sea-skimming method, accelerating the impact at a height close to the sea level at 3 to 5 times the speed of sound, until it finally hits the target and causes damage. . The more advanced advanced anti-ship missiles of
can also be attacked using the "high throw and low hit" method, that is, after the missile is launched, it first climbs up, and then dives diagonally down after it approaches the target. The acceleration of gravity continues to bless the terminal dive speed of the missile, creating trouble for the enemy's interception and increasing the probability of a successful missile strike. The difference between
and the above two strike methods is that the Dongfeng 21D is not first launched from a sea-based or air-based platform, it is a land-based mobile-launched ballistic missile. The launch mode of Dongfeng 21D is different from conventional missiles, but similar to space rockets. In the early stage of launch, it will go through the vertical climb phase of the missile. After that, Dongfeng 21D will climb to the height of the adjacent universe, using a multi-stage rocket propulsion system to continue to the target. Arrive at high speed. When
is about to complete the final stage of the attack, the real power of Dongfeng 21D will appear. With its ultra-long range, the Dongfeng 21D did not directly hit the enemy aircraft carrier with the entire missile, but the fairing at the front end of the missile warhead fell off by itself, exposing one or more warheads contained in it. These warheads have their own independent missile-borne guidance systems and receiving terminals. In addition to self-propelled inertial guidance, they can also respond to the transmission instructions of various guidance signals. That is to say, even in the case of multiple sub-warheads, Dongfeng The final strike trajectory of the 21D is still controllable and can be adjusted manually, and this is what the US Navy fears most. The
conventional anti-ship missile will enter the acceleration phase when it sprints at the end. It can break through the firepower net forcibly with only super-high speed, but its ballistic course can be predicted in advance by the fire control computer, which means it still exists. With the possibility of being shot down by anti-aircraft weapons ahead of time, no matter how fast it is, it cannot be avoided.
The warhead of Dongfeng 21D is not only a "handling from the sky", it is fast enough to approach 10 times the hypersonic speed and it is difficult to lock, and the ballistic course of the warhead is not a purely straight trajectory, and the warhead flying body can receive and transmit. The command signal is used for a second orbital attack, and it is difficult to predict the trajectory and effectively intercept it. The aircraft carrier floating on the sea will still become a target even if it advances at full speed.
