>>Australia, Canada, Sweden, and Spain are four countries that already allow women to serve on submarines, and I think their submarines are more cramped than ours are.
True. And those four countries are well known for having the submarine forces that destroyed the Japanese Navy and choked their nation and then held the USSR at bay for 40 years.
I served on a US submarine that performed a nearly-impossible mission, took on 20,000 pounds of seawater, had damages in every compartment that prevent us from diving again, and we fixed it in 12 hours enough to dive the boat and come home. This is what the American Submariner does. My surface friends have a million stories (and my own experience on the tender confirms it) that when the bad sh!t starts happening, the female sailors get “girly”.
