Royal Navy battleship design continued beyond individual classes

Was the proposed 10-to-15-gun Super Queen Elizabeth the missing link between Queen Elizabeth and later battleship designs?

Only in a limited sense, because it was one product of an almost continuous Royal Navy battleship and battlecruiser design effort.

One paper design should not be treated as the unique bridge between the Queen Elizabeth class and later concepts. The Royal Navy worked on battleship and battlecruiser designs almost continuously, creating many overlapping evolutionary paths. Design activity did not simply stop when a particular class was completed or cancelled. Formal work may have continued until about 1948, and perhaps into 1950.
