There is one country that does have women serving on submarines, which is Australia. Women are serving in practically every other branch of the Naval Service, as well as in the Air Force, Army and Marines. I think this question will be debated intensely for the new few years. If they do serve in submarines there will be very difficult logistics problems. There will not be impossible problems, but challenges will be significant.
Women serving today make a very vital contribution.
I have had a lifelong commitment to education. It would be hard to overemphasize the importance of this in any career. I have also taught at universities since I left the military. But for the present, I would encourage you to remember that academics should be your number one priority. I think that in a few years, regardless of your current view, you will agree with me on that.
