North Korea claims to have successfully tested a hypersonic missile on Wednesday. Other countries are protesting after North Korea launched a hypersonic missile, facing sanctions from various countries. The United States, Russia, China, France and the United Kingdom are working on hypersonic technology. They are also preparing to build missiles using this technology.
The speed of a hypersonic missile is so fast that it travels 5 times the speed of sound in the air. The speed of sound in the air is 3836 MPh. Powerful nations of the world have given priority to the development of such missiles. The main reason for the attention of the superpowers to hypersonic missiles is the weakening of the existing missile defense system in the world. At present, there is no missile defense system in the world targeting hypersonic missiles.
Two types of hypersonic missiles, hypersonic cruise missiles and glide vehicles, are being developed. A hypersonic cruise missile attacks its target at high speed through a jet engine. It belongs to the non-ballistic missile system. A hypersonic glide missile is the first missile to launch into the sky and attack a target on the ground at hypersonic speeds.
The missiles are subsonic, supersonic and hypersonic. The speed of a subsonic missile is lower than that of a sound. These are at speeds of 705 mph. Supersonic sounds are slightly faster than speed. Speed up to 2300 MPh. These occur at speeds up to Mach 1, 2 and 3.
