* '''P-38J''': This production variant was built in 1943 with improvements to each batch, notably an increase of Hp that came with an improved turbocharger. It also included chin radiators, flat bullet-proof windshields, power-boosted ailerons, and increased fuel capacity*  2970 were built. Some were modified to pathfinder configuration and to F-5C, F-5E, and F-5F.{{sfn|Andrade|1979|pp=146–147}}
