One of Vladimir Putin's warships wielding "unstoppable" hypersonic Zircon missiles is playing war games as it heads towards the British Isles via the Norwegian Sea. A promotion on Russian state TV showed the frigate named Admiral Gorshkov "repelling a simulated enemy's air strikes" six days into its mission to scare the West.

March 9 Zircon missiles – the missiles on the boat – are one of the world's deadliest weapons and new to Putin's arsenal. They can travel at speeds of nearly 7000mph.

Russia first tested the weapon in 2020 and then again in 2022 and claimed the test was a success and had flown more than 600 miles at incredible speeds.
