The Dongfeng family occupies a pivotal position in our country. The first time the Dongfeng family was known to outsiders was the Dongfeng-1 short-range surface-to-surface missile. The successful first test launch of the DF-1 dates back to November 1960, and the successful test launch of the DF-1 means that China has begun to rely on itself in missile technology and does not need to rely too much on foreign technology.
With the development of these years, the Dongfeng family has developed more and more and has become a trump card in the hands of our country. Each Dongfeng missile has its own mission.
Since the 50s when anti-ship missiles were equipped with the army, anti-ship missiles of various countries have been cruise missiles. The advantage of anti-ship cruise missiles is that they fly at a low altitude and are not easy to detect by the enemy. The weak point is the slow flight speed, which, once detected, can be intercepted by the fleet anti-aircraft missiles and anti-aircraft artillery. In order to deal with the anti-ship cruise missiles of other countries, the United States has developed the "Aegis" system, which consists of a long-range phased array air defense radar and a long-range air defense missile, which is capable of intercepting most of the world's anti-ship cruise missiles. In order to deal with the US aircraft carrier group and break through the anti-aircraft missile and anti-aircraft artillery interception system of the US aircraft carrier group, China was the first in the world to develop an anti-ship ballistic missile.
When it comes to China's anti-ship ballistic missiles, most people's first reaction is the DF-21D and DF-26. Among them, the DF-21D is an improved version of the DF-21. The DF-21 is a medium-range ballistic missile with a range of 1,800 km to 3,000 km. Its penetration and flight speed are not weak, it can hit targets in a short time, as well as interfere with defense systems. As an improved version, the DF-21D is 15 meters long and has a diameter of 14 meters, there are special motor vehicles to carry and deploy and launch. DF-21D can change trajectory and evade during flight, which greatly increases the difficulty of being intercepted.
When the Associated Press previously reported on the DF-21D missile, it called it an "aircraft carrier killer" because the DF-21D can hit aircraft carriers traveling at sea with high accuracy.
