How building CVA-01 could have reshaped British shipbuilding

How would upgrading British yards to build a large, four-catapult CVA-01 have affected the shipbuilding industry?

It could have preserved larger yards able to compete for major commercial work and supported a much larger carrier-centered Royal Navy.

Enlarging British yards for CVA-01 would have created industrial capacity useful beyond the carrier program, including bids for very large ocean liners. Building several carriers would also have committed political capital and encouraged continued construction of the escorts and support ships needed around them. The counterfactual links one procurement decision to commercial shipbuilding opportunities and a different long-term Royal Navy force structure.
