Why early progress on HMS Glasgow mattered

How was HMS Glasgow's construction progressing?

Very well; an early completion looked possible, which could strengthen the case for keeping the Type 26 line moving with additional ships.

Glasgow appeared to be progressing well enough that an early completion was conceivable. Beyond the novelty of a defense project beating schedule, faster delivery could create room for additional hulls in the production line. The answer links single-ship schedule performance with the strategic value of continuous shipyard throughput.
