Im saying that on the basis of looking toward Korea and the way aircraft were developing. Neither the Jug nor the Lightning were even considered that late and for the reasons I mentioned not simply because there were hundreds of Mustangs lying around. Their time (47s and 38s) was past.
The only P-38 in Korea was a can opener.
Lets face it. The time was past for the 51 as well.
From purely an economic standpoint, the 51 was the better option postwar. From a ground attack standpoint in Korea, the P47N would have been the better bird for ord and loiter time as well as pilot survival. One hit in the coolant tank and the 51 was in trouble. The 51D got the job because it was available in numbers. The casualty rate of Korean war 51s was horrific.
They flew 62, 607 combat sorties in Korea and lost 341 to enemy action. Consider the F80 flew 98,515 combat sorties and only lost 143 aircraft to enemy action. 474 Mustangs were lost to all causes in Korea.
Also understand that P47s were requested for Korea, but logistically it was easier to get 51s as there were a lot of them awaiting scrapping in Japan that were pulled from storage for Korea. It was also easier to draw 51s from the Air National Guard units. There were still Guard units operating 47s but there were no P47 spares in Japan but there were 51 spares so the decision was made to go with the 51.
