How much bonus does a submariner get for for completing their training?

Answer 1

You get nothing for making it through submarine school - you only begin receiving hazardous duty pay when you're assigned to your boat, along with sea pay. As far as training, all submariners from the lowest rank to the CO are constantly in a state of training, so any extra pay has nothing to do with their qualification level. Submarine Duty pay is constantly being adjusted, and like anything in the military, is subject to the whims of the current political administration at any given time.

It does however, affect your crew standing as a FLOB if you're not qualified on any systems (Free Loading Oxygen Breather).
