During the very early days of the Korean war, the U.S. used many Fighter planes for defense. Planes ranging anywhere from the F-9F Panther to the F-86 Sabre. but before these planes were developed and deployed in large numbers. The U.S. was still dependant on using the P-51 Mustang as a front line fighter. How well did the Mustang do against the North Korean fighters (including the Mig)?
Usually, poorly.
The Mustang was clearly outperformed by the jet.
Outgunned, too.
But there were experienced aces among the Mustang pilots, & the MIG pilots weren’t very good, mostly.
So it wasn’t one-sided, & the Mustang boys did destroy some MIGs.
But the handwriting was on the wall–Fighter planes must be jet-powered to survive.
Other types of planes, maybe not.
I haven’t found anything on Korea, but I thought this was interesting:
They must be talking only about Vietnam, as piston aircraft certainly shot down jets in WWII and Korea.
Well, I don’t know about the P-51s, but the first American air victories of the war were scored by F-82 “Twin Mustangs”. This plane was basicly two P-51s spliced together.

I know that against earilier jets (the ME-262) the P-51 often did well, if only because if the 262 pilot tried to engage in a dogfight, he lost his speed advantage and was at the mercy of the Mustang's maneuverability. If the 262 stuck to "boom and zoom" tactics the Mustang was toast.
