MY RANTS.. Funny that is what I think about your comments.I have and that's why I've called BS on just about everything you've posted. It's evident you're biased against the aircraft and you're entitled to your opinions but please don't try to peddle 2nd hand fecal matter here because you'll be called on it. There's plenty of data that shows the P-47 "could have" adequately performed in Korea. It's obvious you have no aviation maintenance experience to understand the difference between radial engines with dry sump oil systems and in line engines with liquid cooling systems. There's no doubt the P-51 was an over all better aircraft in many respects but what you posted in some cases was just half assed BS! If you want to remain a meaningful participating member of this site I suggest you start backing up your rants.
So it's evident - you were just talking out of your ass with regards to a 3 day P-47 engine change...
Here is some information for you why the USAF did not use the Thunderbolt in Korea.
First and foremost it would have never been able to get off the ground
The Thunderbolt would have been a more survivable ground-attack aircraft than the F-51 in Korea, and pilot losses would have been lower in the Jug. However, the plane did have limitations.
The Jug needed a lot of runway to get into the air, which meant the F-47 simply could not have operated from some of Korea's short, rough runways without reducing weapon or fuel loads. One of the Mustang's greatest assets in Korea was that it could fly with a heavy weapons load from undersized dirt runways just a short flight from the front. Fully loaded, the F-47D and F-47N weighed in at 19,400 and 20,700 pounds respectively; the relatively lightweight F-51D topped the scales at 11,600 pounds.
Perhaps most significantly, the Thunderbolt, like all other piston-engine fighters, was outclassed by the straight-wing jet fighters of the late 1940s. The situation became even worse as swept-wing jets entered service. Futrell notes the performance of the Soviet-built MiG-15 jets that appeared over Korea on November 1, 1951 "rendered obsolete every American plane in the Far East." (37) In air combat with the MiG-15
the Mustang had to depend on its maneuverability to survive, since trying to speed or dive away was usually fatal. (38) Vandenberg, in his response to Stratemeyer's request for F-47s, said the Thunderbolt would be much less desirable for aerial combat than the Mustang in the event of a MiG attack. (39)
The Jug could have made an important contribution to the Air Force effort in Korea, but like the Mustang, it would have been replaced eventually by more survivable jet fighter-bombers.
