Dockyard size would shape the successor to the G3

What would follow the G3 if the Washington Naval Treaty were rejected?

Timely dockyard enlargement could support a conventional ship, while delay would preserve G3-like constraints.

The G3's concentrated arrangement partly reflected the size limits of British dockyards. The yards had historically received major infrastructure improvements on a cycle of roughly six years. Completing the next enlargement around 1922 would give designers room to return to a more conventional layout. Delaying that work toward 1928 would keep the successor within the same tight physical limits.
