Not really. The first P-51B-1-NA was completed save Packard 1650-3 which didn't arrive until end (snip)
Simply not enough to go around and the 23rd FG was first in CBI to get a few - not enough to equip the Group until July-August 1944
Ok you have convinced me. They should have got some P-38s or Spit VIII a little earlier then.
Interesting that Caldwell already seems to have had a pretty good idea of the merits of the P-51 in early 1943. Probably rumors about the top speed had filtered around...
