What if the F-15 had been designed for carrier operations instead of developing the F-14 path?
Short answerA joint Air Force-Navy F-15 fleet might have stayed in naval service and displaced the requirement that led to the F/A-18.
NotesIf the F-15 began as a genuinely dual-service aircraft, the Navy might retain it alongside the Air Force. A common pool would make continued upgrades and logistics easier to justify across both services. In that counterfactual, the operational role later filled by the F/A-18 might instead belong to naval F-15 variants.
