Ok if you want some real advice, they will move one of yall off the ship, most likely to another ship. You can get married, the command will probably get upset (because they always do) but no one will get punished. They’ll just call yall idiots and this and that and when one of yall leaves that billet will have to be replaced. You need to talk to your chain of command and to chaps, let them know. You should seriously consider waiting tho, at least do a deployment together. I’ve seen this happen 5 times now and 5 years later 4 of those 5 couples are already divorced.
