Among the fighters that allowed America to win World War II, the P-38 Lightning was uniquely successful and was dubbed the “fork-tailed Devil” by the Germans even though its greatest successes came in the Pacific, Mediterranean, and North African theaters.
Army Air Corps leaders first solicited for what would become the P-38 in 1937 with the specification X-608, a request for a new pursuit aircraft that could fly 360 mph at 20,000 feet, reach 20,000 feet in six minutes, and run at full power at that altitude for at least an hour. They also wanted a long combat radius and plenty of firepower.

Lockheed, a newcomer to the military market, submitted the XP-38, a radical departure from conventional aircraft design that featured three pods and two tails. The outer pods lined up with the tails and each carried an Allison V-1710 engine with 1,000 hp.
