Update:Gerasimov said that the missile hit its target 450 kilometres away in the Barents Sea and hit a Mach 8 speed — eight times the speed of sound.
''Next Week's Nuclear Weapons Deterrent Tests Are Nonsense''
Why Russia's Hypersonic Missiles Can't Be Seen on Radar

According to Popular Mechanics, even if a U.S. ship were to detect a Zircon missile from 100 miles away, it would have only one minute to do something about it.
In order to intercept a Russian Zircon missile, the U.S. would either need to intercept it at launch or fly an object into its path.
Russia's shift to hypersonic weapons is likely a means of contending with American superiority in size, technology and sheer number of aircraft carriers. The U.S. Navy intends to maintain a force of 12 nuclear-powered aircraft carriers.
The age of Russian superweapons is upon us – at least that's what President Vladimir Putin wants us to believe.
And they are cause for concern because the United States' traditional early warning systems might not be able to see those weapons coming.
Hypersonic weapons such as Russia's 3M22 Zircon fly so fast and low at speeds of up to Mach 6 and at a low atmospheric-ballistic trajectory that they can penetrate traditional anti-missile defense systems.
The missile flies with an advanced fuel that the Russians say gives it a range of up to 1,000 kilometers. And it's so fast that the air pressure in front of the weapon forms a plasma cloud as it moves, absorbing radio waves and making it practically invisible to active radar systems.
U.S. Aegis missile interceptor systems require 8-10 seconds of reaction time to intercept incoming attacks. In those 8-10 seconds, the Russian Zircon missiles will already have traveled 20 kilometers, and the interceptor missiles do not fly fast enough to catch up.
Experts say such weapons are currently impossible for the USA to defend against.
The United States will launch a new testing programme for hypersonic weapons, as it seeks to catch up with China and Russia in the arms race.
