Replacement holidays left cruiser fleets aging together

The treaty holiday prevented capital-ship replacement and risked allowing industrial skills to atrophy before a later crash program. Cruiser age rules also divided ships by laying-down date: older C, E, and Hawkins classes faced sixteen-year lives, while newer County-class cruisers received twenty years. This timetable helps explain why the Royal Navy later confronted a concentrated modernization burden. The comparison is with the post-Dreadnought decision to wait for competitors and then rely on emergency construction, which shows the danger of abandoning a steady industrial rhythm.
