Russia has shown how it would launch its deadly new Dagger nuclear system at the west in a Third World War.
The country's Defence Ministry released footage showing the testing of its Kinzhal missile that Vladimir Putin claims can "penetrate any defence."
The missile which means dagger in Russian, can reach speeds of 7,673 miles per hour and can travel 1,243 miles.
It is intended for destruction of surface and waterborne targets.
In the footage, pilots can be seen entering a pair of MiG-31 planes which then take-off.
