Mongo, I am taking a big assumption, but my guess is you are not a woman. I say that for 2 reasons.
1. Every woman knows a woman who got pregnant even when they used a form of BC. Remember the rule is abstinence is the only 100% proven BC
2. A woman who is single typically will not go on the pill. It has medical issues for her in the long run, thus, only those in a committed relationship will feel the need to go down this path. Are you assuming that she should go on the pill because she is going to be on the sub with all of these men and might have sex?
Even a career minded woman is the same as a career minded man and loses sight in this matter when they find "the one".
I hope in your thought process you would now also suggest that all male submariners make sure they guarantee that they don't get her pregnant.
Now onto the next
It would be absolutely no different than replacing someone on a surface ship or aviation squadron. The group commander would pull someone off the staff or go to a sister unit not scheduled for deployment and ask for volunteers, exactly as would be done for any other type command. Not a big deal.
Really? Since when can you pull someone off a staff position and say "go fly the jet". There are regs that every branch follows, and to pull someone into an aviation squadron they must be MQ. They may have flown in a previous assignment, but that doesn't mean they can just hop in a jet and fly now. If you are who you are, you know for a fact that you can't do that. You know you must fly in certain time parameters to maintain MQ status, and you know that many officers when they get to that admin staff position are not MQ for the airframes that are flown, they are there for their "desk" assignment, and not a flying assignment.
Call me silly, but I would think submariners have specialty schools like every other branch has within their service. I would think that you can't take the Intel officer on the sub and now say your job is Intel and Weapons or Maintenance. Afterall, you said there are 15 officers, that means, the majority of that group has a specialty. Granted the hierarchy maybe officers with different backgrounds, but on a whole, the younger officers have job specific backgrounds.
I kind of find it a big deal to me as a citizen that because they could not replace the Maintenance officer since she got pregnant that they now have the Admin officer without any training in charge of the maintenance of the sub. Worse yet, take that same officer and say now your job is Weapons officer.
As far as the asking for volunteers from a sister squadron...I didn't realize that submariners had sister squadrons like surface ships. Again remind me how many are on a sub and how many are on a surface ship? The other point is the key word
VOLUNTEER. In other words they can decline. Granted in 2-3 yrs there maybe enough women submariners, but for the first few years that ability of volunteers will not exist due to BERTHING. They can't bring in the male volunteer because the member they were replacing was a female. They can't bring in a female because she is either in a school to get on the subs or she is on a sub.
Finally, tell me the last time a surface ship was under Antarctica?
