How did cruiser and 5.25-inch gun shortages shape the Didos?

How did the cruiser shortage and the shortage of 5.25-inch guns affect the Dido class?

Cruiser scarcity increased the need for Didos, but the shortage of 5.25-inch guns delayed them; a more conventional triple-turret cruiser might have been easier to produce.

The Royal Navy's shortage of cruisers created demand for more Dido-class hulls. A separate shortage of 5.25-inch guns then slowed delivery because the planned ships could not be armed on schedule. A hypothetical Arethusa-type cruiser carrying three triple turrets in the manner of ARA Argentina offers a comparison with that bottleneck. Such a conventional alternative might have been produced more rapidly. Fleet requirements, hull programs, and weapon production could pull in different directions during rearmament.
