Battleships, hmm? There's a lot of them, so I'll only list a handful that we could use, starting with Japan and the UK.
In no particular order, we have:
Revenge, Royal Oak, Resolution, Ramillies, Royal Sovereign (Revenge-class)
Queen Elizabeth, Barham, Warspite, Malaya, Valiant (Queen Elizabeth-class)
Iron Duke (Iron Duke-class)
Centurion (King George V (1911)-class)
Nelson, Rodney (Nelson-class)
I'll list the German, Italian and Russian ones next time, once I've gotten the relevant details.
