P-51/F-82 vs MiG-15 jet (??)
P-51 and F-80 jet were definitely outclassed by near-supersonic MiG-15.
Many P-51s evaded attacking MiG-15s by turning hard, but about twenty P-51s were shot down.
Did a P-51 ever shoot down a MiG-15?
Books I've read, whose authors researched combat records,
say no type of Mustang ever scored a MiG-15 kill in Korea.
But Mustang pilots Maj. John Yingling and Col. Joseph Rogers claim they shot down MiG-15s.
In Air Force's Airman publication, Yingling claims his MiG-15 kill was confirmed,
and he was awarded a medal, but this was kept off official records since MiG-15 pilot seemed to be Russian.
US Air Force (af.mil):
"Mr. Yingling is a World War II veteran of the Navy and began his Air
Force Service in 1950 at the onset of the Korean Conflict. He is the
only P-51 Mustang fighter pilot to shoot down a MiG 15."
"He [Col. Joseph Rogers] more than made up for his lack of combat in the Korean War --
flying 170 missions in a P-51 Mustang, a piston-engine plane in which
he shot down a Soviet MIG jet."
"On November 8, 1950, the then Capt. Rogers achieved a rare MiG-15 jet
kill while flying in his piston-engine F-51D Mustang named Buckeye
Blitz VI. 'This was unusual because of the speed differences between
the two planes,' said Jim Cook, master crew chief at the Pacific
Coast Air Museum in Santa Rosa and an old friend of Col. Rogers. 'He
was doing around 350 mph, and the jet was doing 450. There were four
MiGs, and they were so much faster. They came over the top of Joe, and
he took a lucky shot at them.'"
On Internet, a reference to the book "P-51 Mustang: From 1940 to 1980"
claims P-51s shot down MiG-15s in South Korea, but reverse seems more likely,
or Mustangs really shot down early MiG-3 propeller fighters (?).
US F-51 pilots trained against US jets and mentioned that scoring a hit on a MiG-15 would be very difficult:
"Although our propeller-driven F-51 Mustangs were no match for the
fast jets in air-to-air battles, we knew from our simulated
'dogfights' between our F-80 jets and the Mustangs, that the '51 could
survive a jet confrontation ...but only if strict, disciplined
defensive tactics were applied, with very precise timing of each
defensive maneuver. For example: the great speed advantage of the
jets could be somewhat offset by the much tighter turning radius of
the Mustang. So, when attacked by jets, the '51 pilot would have to
keep a close eye on the attacking enemy fighter and make an abrupt,
tight turn into the attacker at just the precise moment before the jet
came into firing range. In that way the Mustang would have equal
opportunity to fire at the jet in a head-on pass... trading gun for
gun and for the moment, eliminating the enemy's advantage of speed."
