Bean blogs on naval warfare here. He writes on modern naval warfare (well, from the mid 19th century). His first love is battleships but it goes much wider than this. We talked about battleships (the Yamato in particular), the fate of the French fleet in WWII, whether carriers are obsolete and the Falklands War. If you like this kind of thing then, well, this is the kind of thing you may very well like.
Bean is also a big hit over at Astral Codex Ten where his posts in the comments section generate a lot of interest.
