A 1937 crash program for British cruisers and carriers

With hindsight, what should Britain have changed about its prewar cruiser program?

He would start emergency construction of Arethusa- and Town-class cruisers, Dido-type ships, and carriers around 1936-37, while enlarging the Dido hull for better margins.

The proposed crash programme begins before war makes expansion harder, preserving a mix of light cruisers, larger fleet cruisers, and carriers. Arethusa- and Town-class cruisers would provide the core of that expansion. Carrier construction would grow alongside them rather than wait for wartime pressure. A longer and slightly broader Dido would gain the hull volume and stability needed to fulfil its intended dual-purpose role more successfully.
