There haven’t been any naval battles, but there have been plenty of naval ships sunk.
It’s an expansion of the theatre of war, because it happened outside Iran. The method doesn’t really matter to the theatre of war. It is different that it was a naval vessel hitting another naval vessel. In the past there have been missiles launched from naval vessels that hit ground or air targets, and plenty of naval vessels sunk by missiles or drones. But, I’m not sure how relevant that is.
