    Mitsubishi A6M3 Zero Model 22,
    used in the 2001 film "Pearl Harbor"

    The A6M is universally known as the "Zero" from its Japanese Navy type designation, Type 0 Carrier Fighter, taken from the last digit of the Imperial year 2600 (1940). In the official designation "A6M" the "A" signified a carrier-based fighter, "6" meant it was sixth such model built for the Imperial Navy, and "M" indicated the manufacturer, Mitsubishi.

    The official Allied code name was "Zeke," in keeping with the practice of giving male names to Japanese fighters, female names to bombers, bird names to gliders, and tree names to trainers. "Zeke" was part of the first batch of "hillbilly" code names assigned by Captain Frank T McCoy of Tennessee, who wanted quick, distinctive, easy to remember names.
    At the time of the attack on Pearl Harbor, 420 Zeros were active in the Pacific. The carrier-borne Model 21 was the type encountered by the Americans. Although the Zero quickly gained a fearsome reputation, Allied pilots soon developed tactics to cope with it. When the powerful Lockheed P-38 Lightning, Grumman F6F Hellcat, and Vought F4U Corsair appeared in the Pacific theater, the A6M, with its low-powered engine, was hard-pressed to remain competitive.
