What if the US sea control ship had been built?
Short answerA close version was built for Spain as Principe de Asturias, and Spain later operated the larger Juan Carlos I amphibious carrier with Harriers.
NotesThe answer redirects a counterfactual toward a real design lineage. Principe de Asturias was essentially the sea-control-ship concept realized as a light aircraft carrier. Juan Carlos I then illustrates how the Spanish Navy continued operating a compact aviation ship that combines amphibious and fixed-wing roles. An unadopted American concept could still influence a practical foreign design family.
