Hypersonic missiles refer to missile systems with a speed of more than 5 times the speed of sound (Mach 5). Hypersonic missiles use advanced aviation technology and propulsion systems, which can fly at extremely high speeds, and have the characteristics of rapid penetration, high maneuverability and difficult interception.
The speed of a hypersonic missile depends on the specific model and design parameters, and the speed may vary from country to country and missile system. In general, the speed of a hypersonic missile can be between Mach 6 and Mach 20.
In China, for example, the hypersonic missiles developed by China, such as the DF-17 and the Long March-2F G launch vehicle modification (CZ-2F G), are hypersonic missile systems.
According to reports, the DF-17 missile can reach a speed of more than Mach 10, while the CZ-2F G missile can reach a speed of more than Mach 25.
It should be noted that hypersonic missiles are very fast, much exceeding conventional subsonic or supersonic missiles. Its high-speed flight allows hypersonic missiles to have a shorter range time and greater penetration ability, but it also poses technical challenges in terms of missile stability, thermodynamics and materials.
In general, the speed of hypersonic missiles is usually between Mach 6 and Mach 20, depending on the model and design parameters. The high-speed flight of hypersonic missiles has brought new challenges and opportunities to the military field, and has also aroused the attention of the international community to the arms race and strategic balance.
