How Lion-class battleships would reshape British dockyards

If all the Lion-class battleships were built, would Britain enlarge slips and dry docks only enough for them?

Britain would likely build with margin for the next generation, and the larger infrastructure could enable a different path for postwar carrier design and procurement.

Expensive dock expansion would not stop at the exact dimensions of the current class. Designing additional margin protects the investment against immediate obsolescence and changes what later programs can contemplate. Larger docks and slips could therefore support bigger armored-hangar carrier studies rather than merely accommodating the Lions.
