What would an alternate Admiral class look like?

Would the Admiral class become a better-armoured fast battleship after this version of Jutland?

Yes. The proposed ship is a roughly 28-knot, fully protected successor to the Queen Elizabeth class rather than a conventional battlecruiser.

The battle's design lesson would favour the fast battleship. In this branch, the Admiral class would become an improved Queen Elizabeth design capable of roughly 28 knots with full battleship protection. Renown and Repulse would then be the last British battlecruisers built. More 15-inch guns or larger weapons are possible, but the exact battery remains unresolved.
