Overlooked British warships after Hood

Which warships other than Hood are often forgotten despite how impressive they were?

The Orion, 1911 King George V, Iron Duke, and Town classes are strong examples of overlooked British design progress.

Several British classes are often overshadowed by famous individual ships. Orion establishes the super-dreadnought step, while the 1911 King George V class consolidates a major improvement over it. Iron Duke advances subdivision and solid construction still further, approaching the Royal Navy ideal of a heavily built fighting block. The Town-class cruisers of both world wars broaden the list beyond battleships and show that important design progress also occurred in the cruiser force.
