... The Soviets were flying Merlin Spitfires ... so they were very familiar with both it and the Alison P-39.
I am interested in the P-51 - Corsair losses in Korea. If those are mission losses TAC, or, groundfire inflicted? Many of the F4U missions were launched and recovered from
flight-decks - not ground strips, for the Mustangs.
You seen to dismiss the most fundamental point in my post "... $$$ talks

and the P-51 - even with a licensed engine - was way less expensive to produce than either the P-38 or the the P-47, IIRC - and more basic to maintain in the field. Engineers' thinking."
You have not convinced me that cost-all-in per unit was not decisive in the outcome of the P-51 vs P-47. Hot-Rod vs Cruiser.
P-38 - $97,147 per unit
P-47 - $85,578 per unit
P-51 - $51,572 per unit

"....The AAF's worst accident rate was recorded by the A-36 Invader version of the P-51: a staggering 274 accidents per 100,000 flying hours. Next worst were the P-39 at 245, the P-40 at 188, and the P-38 at 139. All were Allison powered."
