The Wikipedia page for the King George V class battleship indicates that:
Prince of Wales was planned as King Edward VIII,
Duke of York as Anson
Anson as Jellicoe
Howe as Beatty
If KEVIII hadn't abdicated before the class was completed, I would assume that she would have become the lead ship of the class and KGV may have been renamed (my understanding is that she was named thusly for 'continuity' post abdication rather than after KGVI as would have been traditional), or the names rotated: Perhaps our KGV would have become KEVIII and our POW taken another name.
I don't seem to be able to find much corroboration for the original names. Does anyone know how true this is?
Also, on a related note, Lion/Thunderer/Conqueror/Temeraire are names associated with the first four Lion class fast battleships. I'm not aware of any for the other two...? Though things being different perhaps Vanguard...
Any insight would be greatly appreciated.
