I don't know much about modern naval warfare outside of the fact that missiles, torpedoes and small guns are in play but I will say that battleships (at least the type of the WWII and before) aren't much practical anymore (and probably none at all); the closest you'd get are the type like the Arsenal and Kirov ships with one big cannon and a massive amount of missiles (paraphrasing Spacebattle's war room rules on that one). The only way gun based naval battles would make a comeback is if the anti-missile technology is so great that missiles as a weapon are either outdated or regulated to secondary roles and even then something with greater range and tech to do so is needed.
