VLADIMIR Putin is said to be plotting a second test of his unstoppable hypersonic Satan-2 nuclear missile by the end of the year.
The world-ending RS-28 Sarmat missile can blast targets at almost 16,000mph – meaning it has the potential to obliterate the United Kingdom 1,600 miles away in just six minutes.
Politician Aleksey Zhuravlyov previously threatened to nuke Britain with the Satan-2 hypersonic missile in just 200 seconds and wipe out Finland in just ten.
Russia had earlier boasted that the beast – which can carry 15 warheads and drop multiple nukes in a single terrifying strike – would be fully deployed by the end of the year.
But plans for a second test by the end of December has sparked rumours of embarrassing delays in the production of the killer 200-ton rocket.
