This is a response from a non-pilot. Once you learn to fly, you don't need a two-place version of every aircraft you may pilot.

Do you need to go through specific driver training for every different car you drive?

hm doesn't care about the truth, he's an emotional child by choice, a very sad thing .

I actually disagree. No, I am not a pilot. I do fly RC airplanes. Some of the guys I fly with are pilots, some commercial. Some will say RC is harder to fly.
I do believe, after the war started, the US trained their pilots the best. The Japanese and some Germans flew in conflicts before the war started. They did have very good to excellent training programs, up to that point. Also, they got rid of the initial combat jitters. Usually, against fewer and obsolete fighters.
As I mentioned before, the US did switch types of planes on squadrons. Think of going to a race as a driver. You get switched from say a Ford Mustang to a Corvette. Hows your driving skill. You got people shooting at you?
The tide flipped rapidly on the Japanese and Germans in probably late '43. More fighters, more experienced and or better trained pilots, and more advanced planes.

75Sv1; Were any of the newly introduced fighters two-place trainers?

I know at American when I worked there the pilots had to have sim seat time before they got to sit in the real deal. Then they had to be checked out. I'm not a pilot but I spoke with many since I worked crew skd. Planes have different flight characteristics, instrumentation ... etc. Even the SR71's had a flight sim that they learned/trained in.

I believe so. I think even the Germans had some two seat Me-262's. I think two seat P-51s and P-38s. There was the P-82 a twin Mustang, very late in the war. I don't know the number nor the availability. I will not claim to be an expert either. Take that I mentioned Gunther Rahl. I checked and his total was 275 or so. I might have been thinking of Meolders (sp). Just it was much tougher to tally up scores on the Western front and the Pacific.

The P-38 had a lot of variations. I remember a two seat version, and it might have been used as a nightfighter.
