It was a successful twin-engine day fighter in a war in which single-engine fighters predominated. It introduced tricycle landing gear, clear-glass “bubble” canopies, and could outrange any single-engine fighter during the early war years. Its twin-boom layout was unusual though not unique. When the Lightning first flew in 1939, its 400 mph maximum speed seemed like something out of science fiction. Its performance dropped off with altitude, though it remained one of the fastest fighters through the mid-war period. Other US fighters had wing-mounted machineguns that had to be synchronized to converge their fire at specific ranges. The Lightning was more heavily armed, with a 20mm cannon and four machineguns, all mounted in the nose for straight shooting. With a 52-foot wingspan and its twin-engine configuration, the P-38 wasn’t B-17s flying in combat box formations for mutual protection. as nimble in dogfights as some single-engine fighters. Its ability to roll was particularly inferior to that of single-engine planes. Yet it held advantages beyond ers. The most memorable raid of that good speed and rate of climb. For instance, because its counter-rotating propellers period, a strike at the Schweinfurt ball neutralized torque, the P-38 had good turning ability, especially at low speed. bearing works, beyond the range of War Emergency Power & For those reasons, the Lightning could be a dangerous opponent.

Accordingly, on 29 There were several contributing factors. The high altitude required fighters’ favorite tactics was to make head-on attacks against the bombers, followed by October, Gen. Henry Harley “Hap” to escort the bombers—up to 35,000 feet—combined with the tight rolls and high-speed dive aways. The Lightnings couldn’t follow. The diving problem Arnold, head of the USAAF, ordered all extremely cold skies of northern European winter, put stress on the also deprived Lightning pilots of their own otherwise useful escape maneuver. The problem production of those two planes sent engines not previously encountered.
