"Today is a significant event for us – the heavy nuclear-powered missile cruiser Khabarovsk is being launched from the renowned Sevmash shipyard," Defence Minister Andrei Belousov said after Navy Commander Admiral Aleksandr Moiseev smashed the traditional bottle of champagne into the hull of submarine.

The Defence Ministry confirms on Telegram that the new submarine will carry robotic weapons systems "for various purposes."

The Poseidon is a post-doomsday weapon unlike any ever seen in any previous arms race. Formed like a giant torpedo, the weapon is nuclear-powered, nuclear-armed, and can allegedly travel down deep with intercontinental range.
