What the Admiral-class companion battleship might carry

What might the battleship designed alongside the Admiral class have looked like?

Probably a 25-28-knot ship armed with either eight 16-inch guns or ten 15-inch guns.

British design work considered a battleship companion to the Admiral-class battlecruisers. Its likely speed was roughly 25 to 28 knots. The main battery would probably be either eight 16-inch guns or ten 15-inch guns. Those estimates describe a more heavily armed battle-line complement to the fast Admirals while leaving the exact unbuilt design uncertain.
