I think most of these miget subs were taken as close as possible by a surface vessel then launched as close as possible to the target. navigation could only be via a compass but they would have to pick out the course via surface landmarks and then submerge and maintain that course.

Divers have had wrist compasses for some time but I would expect these subs to be fitted with a compass, which would almost certainly have to be illuminated to be used but, once below the surface the effects of currents vary dramaticaly with depth so you can't rely on the same current at the surface affecting you at 50 feet down. Absolutely unbelievable acts of bravery to even attempt such things never mind achieve objectives.
