Russia has released video footage of what it claims to be a successful launch of a new hypersonic missile.
Moscow's defense ministry said the "Kinzhal" was launched from a MiG-31 aircraft on Saturday and successfully hit its target.
The Kinzhal is said to travel at ten times the speed of sound and has a range of two thousand kilometers.
The footage comes about a week after President Putin boasted his country's new and advanced nuclear super weapons.
