@icewaterslim7260 The cheapness came from conscious design. Up until then a run of 200 was considered large. The Mustang was deliberately designed to be mass produced. That was one of the prime factors in selecting it as the primary escort fighter of the AAF. But, yes, the Jug is the way to go, although I have a crush on the Lightning. The later L models were incredible.

Any radial, really. The US Navy went all radial in the 20s. Same for USAAF bombers. Eventually the last generation fighters were all radial as well. There were a few exceptions such as the Spit, but Britain couldn't afford the disruption converting to a new design. The Fw 190 and the Ta 152. All the later British designs were radial, such as the Fury. The USAAF stayed with the Mustang, but as has been pointed out, it enjoyed a massive advantage in cost of manufacture. I cite the P-61 Black Widow in evidence. Big, fast, and maneuverable.

Frankly, by that time jet aircraft were rendering propeller driven fighters obsolete, and the British Fury and late model Spits were fast enough to defeat the buzz bombs. For some reason Republic aircraft always get derisive nicknames. Jug is one (some Brits thought it stood for Juggernaut); the F-84 was called a pig or a hog in Korea because it was in the mud all the time. The F-105 was called the Thud. ... And of course we have the famous Thunderbolt II, the Warthog. Another common factor was the ability to soak up massive amounts of damage. We what could have been when the Navy kept Corsairs on the roster as a CAS platform. It could be used on carriers too small to handle jets.
