This reminds me of the show SeaQuest on SciFi. The only thing that's really different is that the mini-subs they had were much faster and the initial ones were single seaters. It's closer to the one that they competition to Lucas has than the one he was making however.

Yes the one Lucas made was called the Stinger. I'm talking about the one that Tucker made, I forget the name. This was the episode: http://www.tv.com/seaquest-dsv/the-stinger/episode/33397/summary.html?tag=ep_list;ep_title;16
