Russia claims to have created a devastating hypersonic missile that travels five times faster than the speed of sound and could rip through navy warship defences because it's too fast to stop.
The Kremlin's Zircon missile has been called "unstoppable", "unbeatable" and "undefendable" with a 4,600mph speed that only one defence system in the world can destroy – that system is owned by Russia.
The missile employs revolutionary scramjet technology to reach its hypersonic speeds whereby propulsion is created by forcing air from the atmosphere into its combustor where it mixes with on-board fuel – rather than carry both fuel and oxidizer like traditional rockets. This makes it lighter, and therefore much faster.
It uses no fans, rotating turbines or moving parts – just an inlet where air is compressed and a combustor where the air is mixed with fuel. Fewer moving parts also means less chance of mechanical failure.
