That is asking for troubles. Women flying fighterjets? Yes. Serving on combat vessels? Yes. Tank crews? Yes. Combat infantry? Yes. Female generals and chiefs of staff? Yes. All yes to that. But submarines? No, sorry. Cramped space, lacking private sphere - I imagine too much extravagant efforts for too little to be gained from this. Submarines are not the spearhead of civil rights movements. And let'S not be mistaken: laws and rules you can form as many as you want: psychological nature of men and women remains the same, ignorrant of bureaucrat's intentions. It's no good idea to expect that nothing would happen if putting both together in a cramped environment for too long time and with no relief breaks possible.
