Explanation:
Statement 1:
- The statement that the only criterion for being designated as a Hypersonic Missile is the minimum speed is incorrect.
- While speed is a key characteristic of a Hypersonic Missile, it is not the only criterion for its designation.
- Other factors such as maneuverability, range, and altitude capabilities also play a significant role in defining a missile as hypersonic.
Statement 2:
- The statement that a Hypersonic Missile flies at least at the speed of Mach 5, which is 5 times the speed of sound, is correct.
- Mach 5 is equal to five times the speed of sound, which is approximately 343 meters per second at sea level.
- Hypersonic missiles are capable of reaching speeds greater than Mach 5, making them extremely fast and difficult to defend against.
Therefore, the correct answer is 2 only as statement 2 accurately defines the speed requirement for a missile to be considered hypersonic.

Hypersonic Missile: A Hypersonic Missile is a weapon system which flies at least at the speed of Mach 5, i.e., 5 times the speed of sound and is manoeuvrable. The manoeuvrability of the Hypersonic Missile is what sets it apart from a Ballistic Missile, as the latter follows a set course or a ballistic trajectory. Thus, unlike Ballistic Missiles, the Hypersonic Missiles do not follow a ballistic trajectory and can be manoeuvred to the intended target. The two types of hypersonic weapons systems are the Hypersonic Glide Vehicles (HGVs) and the Hypersonic Cruise Missiles. The HGVs are launched from a rocket, before gliding to the intended target, while the Hypersonic Cruise Missile is powered y air breathing high speed engines or ‘scramjets’, after acquiring their target.
The advantages of Hypersonic Missiles: According to a former Commander of the US Strategic Command, General John Hyten, hypersonic weapons can enable responsive, long-range strike options against distant, defended or time critical threats (such as road mobile missiles), when other forces are unavailable, denied access or not preferred. He made this statement while testifying before the US Congressional ~Committee on Armed Services. Conventional hypersonic weapons use only kinetic energy, i.e., energy derived from motion, to destroy the unhardened targets or even underground facilities. Are Hypersonic Missiles detectable in flight? A Congressional Research Service Report on Hypersonic Missiles, released in 2021, states that hypersonic weapons could challenge detection and defence due to their speed, manoeuvrability and low altitude of flight. The Report states that ground-based radars or terrestrial radars cannot detect Hypersonic Missiles until late in the flight of the weapon. This delayed detection makes it difficult for the responders to the missile attack to assess their options and to attempt to intercept the missile. The Congressional Report notes that some analysts have stated that the United State of America’s current command and control model for missile defence would be incapable of processing data quickly enough to respond to and neutralize an incoming Hypersonic Missile.
About the Indian Hypersonic Missile Programme: The Congressional Report states that India is also developing an indigenous, dual capable (conventional, as well as nuclear) Hypersonic Cruise Missile, as part of its Hypersonic Technology Demonstrator Vehicle Programme and has successfully tested a Mach 6 scramjet in June, 2019 and September, 2020. “India operates approximately 12 hypersonic wind tunnels and is capable of testing speeds upto Mach 13,” the Report notes.
