Russia says it has carried out another successful test launch of its Zircon hypersonic cruise missile, fired from the Admiral Gorshkov warship in the White Sea and hit a naval target more than 400 kilometer away.
The defence ministry said it is second test in a fortnight.
The United States, China and North Korea are also involved in the contest to hypersonic missiles as they travel at more than five times the speed of sound in upper atmosphere around 6,200 kilometer per hour.
