Subs going under ice was a saving grace in Civ V. This is downright stupid.
I have found that map generation in Civ VI does tend to block circumnavigation due to ice blockage at the poles. It would be nice if you can at least either go under it or have an icebreaker that allows you to traverse. Being limited to one side or the other is not too fun.
Modern nuclear-powered submarines can (and frequently do) travel beneath polar ice caps. Why wouldn't they? Unlike older subs they don't need to surface to vent diesel exhaust or recharge batteries, they can stay down for months at a time if required. At the end of the day if you have no need to surface you have no need to worry about the ice above you.for the same reason sub's cant dive under Antarctic.

I do take your point that you can't travel under Antartica itself but, as I'm sure you know, this isn't ice related. It's because Antartica is an actual continent that happens to have a lot of ice on it by co-incidence of latitude. You can certainly travel under the massive ice-pack that surrounds the land portion though. At least until it all melts anyway.

This. You should be able to pass under the ice. But Civ games seem to veer from reality more and more with each passing version.
Agreed, just like when nuclear subs attack other subs with missiles, that's Hollywood stuff, ridiculous.
