Russia has manufactured its first batch of high-speed Poseidon apocalypse underwater drones.
The chilling development came as a Vladimir Putin loyalist MP - a prominent retired army general - called on state TV for Britain to be “demolished from the face of the earth” over its support for Ukraine.
Pro-War fanatic Lt-Gen Andrey Gurulev claimed on Rossiya 1 channel that the deployment of British and German tanks “to kill us” was a red line.
Britain could be wiped off the map without resorting to nuclear weapons, he said, stressing: “We have to remember about London so they don't try to steal our victory.
“If it did not exist, there will be victory.”
He also called for an initial giant nuclear test on Arctic island Novaya Zemlya “so the whole earth shudders”.
The military hawk’s genocidal outburst against the UK came as Russian state news agency TASS reported the manufacture of the “first batch of nuclear-armed Poseidon drones”.
The Russian weapon is a giant nuclear-capable torpedo causing radioactive tsunamis laying waste to enemy coastlines.
Earlier another leading Putin propagandist Dmitry Kiselyov notoriously told viewers that Russia should “plunge Britain into the depths of the sea” with its “underwater robotic drone Poseidon” causing a 1,640ft tsunami.
Details of its unique high speed 125mph underwater propulsion system have been a closely guarded Russian secret.
It is alleged to have an “unlimited range”.
In October, it was reported that NATO had sent an intelligence note to its member states warning that Putin had deployed its 604ft-long K-329 Belgorod nuclear submarine, carrier of the Poseidon.
At the time it was believed to be on a mission to test the fearsome weapon.
A source told TASS today: "The first batch of Poseidon ammunition has been manufactured and will be soon delivered to special-purpose nuclear-powered submarine Belgorod.”
The same source from the Russian military and defence industry said trials of core components of Poseidon underwater drones, including the nuclear power unit, were successfully trialled.
Putin sees the Poseidon as a key to his ultimate military supremacy over the West, it has been reported.
Gurulev - a key mouthpiece for high-ranking hardliners - sees Britain as lynchpin for the West’s unity with Ukraine, and instigator of military supplies to Kyiv.
He told state TV that the expected deployment of German tanks has an historical significance which changes the conflict.
“The appearance of German tanks on Russian territory is the cornerstone of any war,” he said, even though if the move goes ahead they would be for defensive use in Ukraine, not on Russian soil.
“As soon as Leopard-2 tanks get here, be ready [for full war],” he said.
“Britain will supply 12 Challenger-2 tanks, you have to take this seriously. It's against us, it's to kill us…. These guys are getting cocky. They have no brakes.
“Should we use nuclear weapons? Why should we be embarrassed to talk about our resolve if there is a threat to Russian territory?
“And Leopard tanks will be riding in Russia, in [our] Nazi-occupied Kherson and Zaporizhzhia regions.”
In fact, these are Putin-occupied regions of Ukraine, and not Russian territory.
He demanded: “Who is stopping this from happening? Start with the resumption of nuclear weapons testing…
“Drop the mother of [all bombs] on Novaya Zemlya [in the Arctic], so the whole earth shudders. Next time we should hit the lid of the coffin.
“About Britain, I said six months ago that it should be demolished from the face of the earth.
“This can be done without engaging the nuclear triad, without our submarine forces with intercontinental ballistic missiles, silos or mobile launch systems.
“We have enough firepower without it. But we have to make it clear - one more time and this will come….
“Our President [Vladimir Putin] said that at this stage everything is going according to the plan of the Defence Ministry and the General Staff, this is true. But I am sure that the plans do not include the presence of German tanks on our soil.
“The special operation has been going on for almost a year. [The people are with Putin]. They will do whatever it takes to win.
“But we have to remember about London so they don't try to steal our victory.
“If it did not exist, there will be victory.”
Kiselyov — avidly watched by Putin and a top executive in Moscow’s powerful state media propaganda machine — told viewers in May that an option was “to plunge Britain into the depths of the sea" is Russian underwater robotic drone Poseidon.
“It approaches the target at a one kilometre depth with the speed of 200 kilometres per hour [125mph]. There is NO way to stop this underwater drone.
“It has a warhead with a capacity of up to 100 megatons. The explosion of this thermonuclear torpedo close to Britain's shores will raise a giant wave, a tsunami, up to 500 metres [1,640ft] high.
"This tidal wave is also a carrier of extremely high doses of radiation. Surging over Britain, it will turn what is probably left of them into radioactive desert.
“Permanently unusable for anything. How do you like this prospect? And Putin warned about this, back on February 24 [if anyone interfered with his special military operation].”
Chief analyst of the Russian General Staff, Admiral Igor Katasonov has said: ”Unique characteristics of the Poseidon system will help the Navy to successfully combat aircraft carriers and strike groups of a potential adversary in any oceanic theatre of war and destroy shore infrastructure facilities.”
