A Ford-class carrier in the 1920s would trigger a global shock

How would the United States react if a South American state built a Ford-class carrier in the 1920s?

The United States and other powers would panic because the ship would reveal a technological and industrial gap far beyond anything the period could match.

A South American state producing a Ford-class carrier during the 1920s would cause panic far beyond the Americas. The ship would be separated from contemporary naval construction by an extraordinary technological gap. Existing powers would face capabilities and industrial methods they could not readily match or explain. The comparison is explicitly counterfactual and uses a Wakanda-like shock to convey the scale of the disruption, rather than presenting the scenario as plausible history.
