Just watch. The Belgorod K-329 is a Russian spy submarine. It is a modified Oscar II class nuclear submarine. The massive 184-meter long vehicle displaces 24,000 tons of water submerged. It can only travel at 60 kmph (37 mph), which is not terribly impressive. However, it doesn't need to get very close to its targets to show them absolute destruction. Not only can it carry multiple smaller submarines, such as the espionage submarine Losharik AS-31 and the Klavesin-1R UUV, it is equipped with six Poseidon drones/torpedoes. These 20-meter drones are powered by 15 MW nuclear reactors and carry a warhead that can be anywhere from 2 megatons to several dozens. These drones can travel 10,000 kilometers before running out of fuel, which means the Belgorod could drop one off in Asia and it could hit America.
