Lockheed modified 200 P-38J airframes in production to become unarmed F-5B photo-reconnaissance aircraft, while hundreds of other P-38Js and P-38Ls were modified at Lockheed's Dallas Modification Center to become F-5Cs, F-5Es, F-5Fs, or F-5Gs. A few P-38Ls were field modified to become two-seat TP-38L familiarization trainers. During and after June 1948, the remaining J and L variants were designated ZF-38J and ZF-38L, with the "ZF" designator (meaning "obsolete fighter") replacing the "P for Pursuit" category.
