Whaaa? Much higher stall speed, less reliable and non-redundant engines, a smaller cannon, no titanium cockpit shell, no redundant tail fins, and smaller wingspan that won’t keep it flying should a chunk of wing go missing? Also, good luck taking off from the runways the A-10 uses.

They don’t even need to build more of them, we already have 300 of them, and most have been highly upgraded.

Just build more A-10s. Did they lose the engineering drawings or something? It’s not like there is anything better for its role anywhere. Just update what needs updating and leave the rest alone. retool as required. It would be cheap as far military plane development projects go. Oh wait, that’s why they aren’t doing…
