Submarines and other such military things are nation state based. While there is accent variation within nations it would be less than on a multi-national science project.
or it could be it has never been tested and there is language drift in long term and isolated military deployments.
I’m pretty sure there’s a stereotypical (slight) difference in how military people talk, though granted it’s probably to a large part because they’re forced to talk in a specific way a lot of the time.
