take a look at this diagram of the inside of a nuclear submarine there's a lot going on here this is one of the most powerful weapons in the world because of this it's a nuclear reactor that breaks apart atoms to create an immense amount of energy that quietly Powers this sub without it ever having to come up to the surface for air before they could put nuclear power plants on submarines they used diesel engines which needed to come up to the surface to get air to run their engines but nuclear submarines don't have to resurface
ever the US has a massive Fleet of these things some of them loaded with nuclear warheads that are attached to these huge rockets that launch directly from the sub at any given moment there are a handful of these Subs roaming around anywhere on Earth from months at a time and nobody knows exactly where and that's the whole point
