As the P-38H, 600 Lightnings with an improved 20 mm cannon and a bomb capacity of 3,200 lb were produced on one line beginning in May 1943 while the near- definitive P-38J began production on the second line in August 1943. The Eighth Air Force was experiencing high-altitude and cold-weather issues which, while not unique to the aircraft, were perhaps more severe as the turbosuperchargers upgrading the Allisons were having their own reliability issues, making the aircraft more unpopular with senior officers out of the line. This was a situation unduplicated on all other fronts where the commands were clamoring for as many P-38s as they could get. Both the P-38G and P-38H models' performances were restricted by an intercooler system integral to the wing's leading edge, which had been designed for the YP-38's less powerful engines. At the higher boost levels, the new engine's charge air temperature would increase above the limits recommended by Allison and would be subject to detonation if operated at high power for extended periods of time. Reliability was not the only issue, either. For example, the reduced power settings required by the P-38H did not allow the maneuvering flap to be used to good advantage at high altitude. All these problems really came to a head in the unplanned P-38H and sped the Lightning's eventual replacement in the 8th Air Force; fortunately, the 15th Air Force was glad to get them. The Lockheed P-38 Lightning is an American single-seat, twin piston-engined fighter aircraft that was used during World War II. Developed for the United States Army Air Corps (USAAC) by the Lockheed Corporation, the P-38 incorporated a distinctive twin-boom design with a central nacelle containing the cockpit and armament. Along with its use as a general fighter, the P-38 was used in various aerial combat roles, including as a highly effective fighter-bomber, a night fighter, and a long-range escort fighter when equipped with drop tanks. The P-38 was also used as a bomber-pathfinder, guiding streams of medium and heavy bombers, or even other P-38s equipped with bombs, to their targets. Used in the aerial reconnaissance role, the P-38 accounted for 90 percent of the aerial film captured over Europe. Although it was not designated a heavy fighter or a bomber destroyer by the USAAC, the P-38 filled those roles and more; unlike heavier German Zerstörer designs crewed by two or three airmen, the P-38 with its lone pilot was nimble enough to compete with single-engine fighters. The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the aircraft of America's top aces, Richard Bong (40 victories), Thomas McGuire (38 victories), and Charles H. MacDonald (27 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the introduction of large numbers of P-51D Mustangs toward the end of the war. Unusual for an early-war fighter design, both engines were supplemented by turbosuperchargers, making it one of the earliest Allied fighters capable of performing well at high altitudes. The turbosuperchargers also muffled the exhaust, making the P-38's operation relatively quiet. The Lightning was extremely forgiving in-flight and could be mishandled in many ways, but the rate of roll in early versions was low relative to other contemporary fighters; this was addressed in later variants with the introduction of hydraulically boosted ailerons. The P-38 was the only American fighter aircraft in large-scale production throughout American involvement in the war, from the Attack on Pearl Harbor to Victory over Japan Day. …
