The Royal Navy's unbuilt 1916 armored-cruiser studies

What might a Royal Navy World War I armored cruiser have looked like?

The surviving studies point to an approximately 18,000-ton ship, probably involving 9.2-inch guns, with potentially important treaty consequences.

National Archives evidence records studies around an 18,000-ton design, with debate involving 9.2-inch guns. The ship would have revived a large armoured-cruiser category during the First World War. An order in 1916 might have produced serviceable ships before the conflict ended. Their survival would then have complicated interwar treaty categories by preserving a type between conventional cruisers and capital ships.
