British infrastructure would keep moving with a capital-ship race

Would British infrastructure stop the Royal Navy at the practical limit of capital-ship size?

Not if the arms race continued; Britain would keep upgrading its yards and docks to support the next several ship generations.

British docks and yards would impose limits only if the country stopped renewing them. In a continuing qualitative race, the Royal Navy would also restart its cycle of infrastructure improvement. The comparison given here has France upgrading for the next generation, the United States planning several generations ahead, and Britain revisiting its facilities on roughly a six-year cycle. British planning would aim to cover about three coming ship generations within each program. Larger capital ships would therefore drive yard investment instead of meeting a fixed historical ceiling.
