Huge dry docks enable fast capital-ship choices

How would World War II change if Britain received two dry docks in 1918 large enough to hold multiple Hood-sized ships?

Such docks would open a much broader fast-fleet program, including G3s and large carrier conversions from the remaining Admiral-class hulls.

Dry docks large enough to handle multiple Hood-sized ships would let Britain build or maintain almost anything it wanted. In that counterfactual, the G3 battlecruisers would be accelerated and the remaining Admiral-class hulls converted into carriers. The additional dock capacity makes fast carrier and capital-ship squadrons more realistic.
