I know its defence talk but its interesting for sure! Would American SeaWolf class submarine be considered 5th+ generation?
Sea Wolf was probbaly the first true 5th gen sub and it is nuclear. Now the US has the Virginia class and the Brits have the Astute class, which I would also call 5th generation. But all nuclear.
I would argue that the German Type 212 and the Japanese Soryu also would be called 5th generation. The later Yuan Class may be too...but we just do not know enough about them. They are AIP Diesel/Electrics like this new Russian design and would be more comparable.
AIP Diesel electric boats are very quiet, but they are also slow and do not have the endurance of a nuclear attack sub. They also generally carry a far smaller weapons load.
The newer 5th generation nuclear powered attack subs are also very quiet...but not quite as quiet as an AIP diesel/electric subs moving very slowly or holding position on electric power only. But a nuclear sub is much faster (both submerged and on the surface), carrier a lot more weapons, and it has a LOT more endurance at sea.
AIP diesel electrics are dangerous in the littoral waters, at choke points, or if they know where a task force, convoy, or large ship is going to be and can lay in wait for them. But they would have a tough time cacthing up with, or keeping up with any Surface Action Group or Carrier Group in transit on the high seas.
