Platforms mentioned are the Air Independent Propulsion (AIP) Swedish Gotland (Sterling Engine), German 212A (PEM Fuel Cell), German 214 (PEM Fuel Cell), Spanish S-80 (Rankine Cycle Ethanol-Oxygen Steam) and others.
An Autonomous Underwater Vehicle (AUV) transport option for the SSK platform may mitigate some of its less advantageous characteristics (e.g. endurance, indiscretion, and speed).
Wonder if our navy or submarine builders have a recent "make-buy-lease" analysis for the various AIP platforms?
