Why Britain could not rebuild every capital ship at once

What if Britain accepted the temporary loss of availability and rebuilt most of its capital ships during the 1930s?

It could produce a much stronger modernized fleet, but only by carefully sequencing refits through years of overlapping international crises.

Britain did not need American yards to modernize Hood, the Nelsons, and older battleships; commercial and naval yards could perform the work. The constraint was operational availability during the Abyssinian crisis, Spanish Civil War, and Japanese expansion in China. A stronger program would prioritize Queen Elizabeth-class ships and fast capital ships such as Renown, Repulse, and Hood before spending heavily on the R class. The discussion shows that refit policy is a scheduling and deterrence problem as well as an engineering one.
