Mitsubishi A6M2 Zero
In 1937, the Imperial Japanese Navy issued a requirement for a replacement for the Mitsubishi A5M then entering service. The IJN wanted a carrier-capable fighter with a top speed of 300 mph, an endurance of eight hours, cannon armament, good manueverability, with a wingspan less than 40 feet—the width of elevators on Japanese aircraft carriers. All of this had to be done with an existing powerplant. Nakajima promptly declared that the IJN was asking the impossible and did not bother trying to submit a design.
Mitsubishi’s chief designer, Jiro Horikoshi, felt differently and began working on a prototype. Using the Nakajima Sakae 12 as the powerplant, he lightened his design as much as physically possible, leaving off all crew armor and self-sealing fuel tanks, and using a special kind of light but brittle duralumin in its construction. Though it delayed production, the wing and fuselage were constructed as a single piece for better durability. Using flush rivetting also made for an aerodynamically clean design; it had a stall speed below that of any contemporary fighter at 70 mph. Its wide tracked landing gear also made it fairly simple to recover on both carriers and land on unimproved airstrips. Horikoshi had delivered, and the IJN accepted the new fighter into service in July 1940 as the A6M Rei-sen (Type 0), referring to the Imperial calendar date used by the Emperor of Japan; 1940 was Imperial year 2400. Both friend and foe would refer to the A6M simply as the Zero.
The Zero had its first combat encounter with Chinese Polikarpov I-16s in September 1940. Claire Chennault, the American advisor to the Chinese Nationalists, sent reports of this amazing new fighter to the United States, but he was ignored. The Allies would therefore learn of the Zero’s prowess first-hand on 7 December 1941 at Pearl Harbor. Making matters worse for the Allies was that the Zeroes they encountered were flown by IJN pilots, who were among the best in the world. Teaming elite pilots with a supremely manueverable fighter was a deadly combination that seemed unstoppable in 1942, when Zeroes over New Guinea sustained a kill ratio of 12 to 1 over Allied opponents.
Even at this dark stage of the war for the Allies, however, their pilots were learning the Zero’s weaknesses. Hirokoshi’s sacrifices had given the Japanese a fast, manueverable, and very long-ranged fighter, but it had come at a price. P-40 and F4F Wildcat pilots in China and the Pacific learned that the Zero, lacking any sort of armor or self-sealing fuel tanks, was very prone to catching fire and exploding with only a few hits. They also learned that the best defense against a Zero was to dive away from it, as Japanese pilots could not keep up with either the P-40 or the F4F in a dive, as it would tear their fragile fighter apart.
Japanese pilots also learned that the rifle-caliber 7.7mm machine guns in the Zero’s cowl were ineffective aganst armored Allied fighters, and the 20mm cannon often had poor fusing on the shells. The Allies gave the Zero the reporting name “Zeke,” while later models were codenamed “Hamp” and floatplane A6M2-Ns were codenamed “Rufe,” but most pilots continued to call it the Zero.
As World War II continued, the Allies began drawing on those lessons in fighter design, helped immensely when an intact A6M2 was captured in the Aleutians in summer 1942. First to arrive was the F4U Corsair, which still could not turn with the Zero but was faster and better in a climb; the second was the F6F Hellcat, which was also faster and better in the vertical, but could stay with the Zero in a sustained turn. The Allies also benefited from the Japanese losing so many experienced pilots in battles such as Midway and the Guadalcanal campaign: the IJN’s pilot replacement program was too selective, and could not replace the heavy losses of 1942 and 1943. As a result, by late 1943, the Zero menace had been reduced drastically; the Battle of the Philippine Sea—which US Navy pilots named the “Great Marianas Turkey Shoot”—brought this out dramatically, when nearly 700 Japanese aircraft, a significant number of which were A6Ms, were shot down with less than 40 losses amongst the Americans.
While the Zero was still deadly in the hands of a good pilot, these pilots were increasingly scarce by 1945. Though Mitsubishi kept upgrading the Zero throughout World War II, the design simply was too specialized. By 1945, it was being used mainly as a kamikaze suicide aircraft, flown by half-trained former college students. While the kamikazes did a great deal of damage and killed thousands of Allied sailors, it was a desperation tactic that only lengthened a war that Japan had already lost. The Zero had exacted a price, however: it was responsible for the loss of 1550 Allied aircraft, a conservative estimate.
By war’s end, 10, 939 A6Ms had been built and Mitsubishi was working on a replacement, the similar A7M Reppu. Of these, the aircraft that survived the war were mostly scrapped and few preserved, and no flyable aircraft were left; directors attempting to make World War II movies were forced to convert a number of T-6 Texan trainers to look something like Zeroes. A few have since been restored to flying condition. Today, about 17 Zeroes remain, though some are being recovered from wartime wreck sites and restored to museum display.
This particular A6M2 was built by my dad from the Otaki 1/72 kit. It depicts V-103, the aircraft flown by third-ranking (and top surviving) Japanese ace Saburo Sakai. Sakai was flying this aircraft in 1942 when he was badly wounded by a SBD Dauntless tail gunner, and somehow managed to fly six hours back to Rabaul. Sakai survived his wounds (which included the loss of an eye) and the war. V-103 is shown in standard IJN light gray, with a blue identification stripe and black cowling.
