Yep, he's a "bubblehead"... he's also a "nuc" (slang that KillarneyRose told me)... works on a nuclear submarine, can't really tell me anything specific that they do. He went to "nuc school" after finishing at the Academy. We haven't really talked specifically about what level of communication he has when he's out on the sub.... but I don't think it's much.
Does anyone know of any good websites with basic navy info on it? Cliff notes to navy stuff
Thank you so much for your advice, AlphaSigOU!
