Description of Models

I have read that the first production versions of the Lightning were not as fast as expected, and had a low service ceiling, due to a mismatch of turbochargers and engines. Apparently this was due to the prevailing procurement procedures of the period - the USAAF chose, ordered and delivered the parts to the manufacturer. This was rectified on later models.

The P-38F version of late 1942 was the first Lightning version that was considered fully combat-ready.

The P-38G Version, most widely built of the early Lightnings, began to roll off the production lines in June of 1942. It was basically similar to the P-38F apart from a change to the Allison V-1710-51/55 (F10) engine with increased boost ratings and offering 1325 hp for takeoff.

Unarmed photographic reconnaissance versions of the P-38G were also produced under the designation F-5A.

The P-38H differed from earlier versions in being powered by 1425 hp Allison V-1710-89/91 engines.

The P-38J version, which first began to appear in August of 1943, introduced some appreciable differences in the geometry of the engine nacelles which make this and later versions easily distinguishable from earlier versions of the Lightning.

The P-38L was the final production version of the Lightning and was numerically the most important of all the Lightning versions. Lockheed built 3810 P-38Ls and Consolidated-Vultee at Nashville built 113 more. The P-38L was powered by 1475 hp Allison V-1710-111/113 engines with a war emergency rating of 1600 hp at 28,700 feet and a military rating of 1475 hp at 30,000 feet.

Lockheed adapted the P-38L as a two-seat night fighter designated the P-38M. This modification was successful, and provided the USAAF with a night fighter having a top speed of 406 mph at 15,000 feet as compared to only 369 mph at 20,000 feet for the Northrop P-61A Black Widow.
