My brother was stationed on an Ohio class and they actually did do their research. One of the many reasons he picked being a submariner was that rules are a lot looser underway, and yes they are doing a pilot program with having women serve on subs by teaming female officers with female enlisted sailors. The reason rules are looser is best summed up by the whole metaphor of an oak tree vs a willow tree. Shoving a bunch of guys in a steel tube with no daylight, and you take away the 24 hour day (my brother's "days" were 18 hours long) is already asking a lot of them, you add in the all of the many many navy regulations and your going to have people snap, something that is a lot more dangerous in a sub then an aircraft carrier. The sub fleet takes care of their own, my brother could get away with all sorts of crap on the base, another officer would yell at him for walking around with his hands in his pockets (it was cold) and not saluting and would go and report him to his captain, who never took any action, but for example on aircraft carriers there are peoples who's job it is to write up stupid small infractions. Oh, and, emergency deep is something that is practiced in a maneuver called angles and dangles, it always sounded like that would fun to experience, though not fun enough to enlist

Random fact, there are basically two main classes in the sub fleet (technically there is more and you can google it if interested) and then there is the seawolf class, but the two main ones are:
Los Angeles class
These are attack subs and can be deployed for months upon months and only have one crew assigned to it. They are small and cramp.
Ohio class aka boomers
These are the ones that carry the nukes, they're larger hence the reason they're doing a pilot program with allowing women serve on board. They go out with one crew for a 3 month tour, come back, spend a month being refitted, then are sent out with another crew for a 3 month tour....after all they are only worth anything as they circle around the ocean waiting to get the order to release their ICBMs.
While the whole purpose of an Ohio class is to fire it's nukes, I think it is human nature to take that moment and question becoming the first person to deploy a nuclear bomb as weapon since WW2, yes they broke protcol by breaking radio silence and even deploying the antenna, but I still find it plausible....in a Hollywood sort of a way.
