What later aircraft would be practical but still overwhelming if introduced during 1937-45?
Short answerA fully developed Hawker Sea Fury, probably a late export-standard version, would combine practical piston-aircraft support with decisive fighter performance.
NotesModern jets would be impractical in a Second World War setting because of their fuel, maintenance, and operating requirements. A piston fighter from just beyond the period offers a more credible advantage, with the Hawker Sea Fury as the preferred choice. Its speed and mature design would leave contemporary opponents with few credible answers. The choice separates genuine technological overmatch from equipment that a wartime force could actually operate.
