VLADIMIR Putin reportedly tested his hypersonic Satan-2 nuke missile while Joe Biden was visiting Ukraine. The Russian leader is said to have warned the US president of the test launch in advance.

But the test launch of the missile – capable of delivering multiple nuclear warheads – appeared to have failed, officials said. US officials believe Putin would have highlighted the success of his test in his speech to the nation on Tuesday. Sources said they didn’t consider the launch to be an escalation. The weapon has the potential to obliterate the United Kingdom 1,600 miles away in just six minutes. And with an operational range of up to 11,180 miles, the deadly missile is reported to have no equivalent in the West in terms of the terror it could unleash. It comes amid fears Putin is readying the launch of the missile to coincide with the Kremlin’s massive offensive planned in days. Officials in remote districts of Kamchatka, Russia, have been warned to be ready for a test launch of the missile between February 15 and February 25. Hundreds of thousands of soldiers said to be gearing up for the push, which will mark the one-year anniversary of Russia’s invasion of Ukraine on February 24. Ukrainians are bracing for the new assault that is set to include 1,800 tanks, 3,950 armoured vehicles, 400 fighter jets and 300 helicopters incoming from Russia. Putin is also gathering 2,700 artillery guns and 810 rocket launchers for the “new wave of attacks”, according to Foreign Policy. There has only been one definitive test flight of a Satan-2 missile, which happened in April, 2022.
