Russia’s Defense Ministry released footage of what it said was a successful test launch of its new submarine drone missile system, hours after President Vladimir Putin said there had been major advancements in the system.

Putin announced the development of a series of new advanced weapons ahead of his re-election in March 2018. Of those, Russia has since deployed the Peresvet laser weapon, continues testing the Burevestnik nuclear-powered cruise missile and nears completion of its unmanned Poseidon nuclear-powered submarine.
