Hey, while we're discussing this--what was the approximate dates that the 5th AF P-38 groups would have had a majority of P-38Ls in theater versus the J?
The L's showed with the 475th FG in late September early October 44. I'm not home at the moment, so I'm not sure on the specific squadron, but one of the squadrons got the Ls first, then another with the third sticking with J's the longest. I think it's safe to say the groups didn't have a majority of L models until December 44-January 45. It's also fair to say that the majority of the air to air combat in the Pacific was flown in the F,G, H and J models. The 80th for example got it's last kill of the war in January 45. The 5th AF 38s ran out of targets and did a lot of ground support work after that.
The 38L also showed up in the ETO in early October 1944. The 474th FG had 38s until the end of the war in Europe and they had a mix of Js and Ls right til the end, including some J-10s and 15s that didn't have dive flaps or power assisted controls.
The problem is there were J-25s prior to this, and they look identical to L-1s
