No-treaty Royal Navy renewal

Without naval treaties and with 20 years of construction, would the Royal Navy avoid block obsolescence in its cruiser and battleship forces?

A steady program could replace World War I-era battleships by the early 1930s, assuming roughly four new battleships every two years.

The treaty-free scenario is a question of replacement rhythm rather than a single ship design. With a notional 24-battleship force and four ships every couple of years, the Royal Navy could have a modern battle fleet by about 1932-33. Continuous construction would change the age profile of the fleet before a later crisis arrived.
