Russia successfully tests hypersonic missile ‘which makes Western defences obsolete’

 Russia has conducted five successful test flights of a hypersonic missile which is almost impossible to intercept – and which renders Western defences ‘obsolete’.

The Zircon missile can travel at between 3,800mph and 4,600mph – five to six times the speed of sound.

The speed of the Zircon missile makes it extremely difficult to target with anti-missile systems – and it could render Western defences ‘obsolete’, according to defence analyst Tim Ripley.

Ripley said, ‘It will greatly reduce the reaction time that they (Western military units) have to deploy their own defenses and counter-measures.’
Military analyst Vladimir Tuchkov told Russian state media, ‘In Russia, the testing of actual weapons is already underway.

‘It is expected to be added into Russia’s arsenal between 2018 and 2020’.

Hypersonic speed
Speed that is highly supersonic Also called Hypersonic transports; HST
In aerodynamics, a hypersonic speed is one that is highly supersonic. Since the 1970s, the term has generally been assumed to refer to speeds of Mach 5 and above.

The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5. The hypersonic regime is often alternatively defined as speeds where ramjets do not produce net thrust.
‘A speed of Mach 6 is more than enough of a guarantee to overcome any anti-missile system.’
