What I meant, however, was not a complete AIP system for all propulsive need, but rather a "crawl" system, so that you can save your stored oxygen and keep the batteries fully charged for bursts of speed, and not waste them just swimming about at a few knots.
You don't need 4.4 MW to propel the sub at 2-3 kts! Imagine instead a system capable of, say, 100-200 kW. Using your numbers, that would mean no more than 20-40 tons. But I also think that your numbers relate to stand-alone units with all subsystems included. In a large array, some parts are likely only needed once or a few times, lowering the total weight.

Sorry about that I cut and pasted from a word processor doc and it was all black. Highlight to see better.
The problem is that RTGs need to be in an array since one unit can't exceed 1 kW of power.
