About Hypersonic Missiles
- Hypersonic missiles are advanced weapon systems capable of travelling at speeds exceeding Mach 5 (five times the speed of sound, approximately 6,125 km/h).
- Key Characteristics:
- Speed: Hypersonic missiles travel at speeds of Mach 5 or higher, enabling them to cover vast distances in a fraction of the time compared to traditional missiles.
- Manoeuvrability: Unlike ballistic missiles, which follow a predictable arc, hypersonic missiles can manoeuvre during flight, making them challenging to detect and intercept.
- Trajectory: They fly within the atmosphere (at altitudes of 20-100 km), avoiding traditional ballistic arcs and complicating radar tracking.
- Types of Hypersonic Missiles:
- Hypersonic Glide Vehicles (HGVs): HGVs are launched by rockets and glide to their targets at hypersonic speeds.
- Hypersonic Cruise Missiles: They are powered by scramjet engines, maintaining sustained hypersonic speeds throughout their flight.
Mach Number |
Ratio of the speed of an object to the speed of sound in the same medium is called the Mach number.
