Your quote above talks only about 'normal' Diesel vs. Nuclear. AIP means 'air independent propulsion' and it comes in different concepts. There are some 'older' AIP-systems which 'only' allow to run the diesel submerged without snorkel. With most modern 'true' AIP (fuel cell) you don't need the diesel at all.

I thought that fuel cells were still not efficient enough to allow full autonomy. I thought they operated more like "more efficient batteries" in modern diesel subs. What is the current autonomy of a fule-cell-only sub?
