Vladimir Putin is assembling a secret fleet of super submarines which could topple NATO and plunge the world into war.
A report by naval experts warns that Russia already has a small but sophisticated army of subs which are capable of launching missile strikes across the globe.
The deadly group of stealthy underwater weapons are currently patrolling the world and have already reportedly breached UK waters having approached the Royal Navy’s base in Faslane, Scotland.
Russia is stepping up its secret submarine programme to ‘Cold War’ levels and experts warn NATO members “no longer” have the defences to stop the aquatic death machines.
Andrew Metrick, who co-wrote the report for the Center for Strategic and International Studies (CSIS), said: “Russia operates a small number of very small, nuclear powered submarines that are capable of diving in excess of several thousand meters.
“You can imagine what a clandestine deployable deep submergence vehicle could be used for.
