Changes
→Historical Information: I excluded A6M2 and "Model 21" because the initial sentence refers to the A6M series as a whole. But here, I've modified it to make the A6M2 the main subject. Also fixing paragraph 2 a little.

The '''Mitsubishi A6M2''' '''''Type 0 Model 21 Carrier-based Fighter''' ''(also called Rei-sen, but typically "Zero-sen", with the Allied reporting name "Zeke") was the predominant Japanese naval fighter of World War II. The 0 in its designation referred to the last digit of Imperial year 2600 (Gregorian year 1940) which it entered service. When encountered, it was codenamed ''Zeke'', but eventually "Zero" became commonplace in Allied speaking.
The '''Mitsubishi A6M2''' '''''Type 0 Model 21 Carrier-based Fighter''''' is the initial production variant of the '''A6M ''Type 0 Carrier-based Fighter '''''(also called ''Rei-sen'', but more commonly "''Zero-sen''", with the Allied reporting name "''Zeke''"), was the predominant Japanese naval fighter of World War II. The ''0'' in its designation referred to the last digit of Imperial year 2600 (Gregorian year 1940) which it entered service. When encountered, it was codenamed ''Zeke'', but eventually "Zero" became commonplace in Allied speaking.
Development by Mitsubishi started in 1937 as the preceeding [[Type 96 Fighter|Mitsubishi A5M]] (''Type 96 Carrier-based Fighter)'' was entering service as the Imeprial Japanese Navy began to consider its eventual replacement. Specification ''12-shi'' was sent to Nakajima and Mitsubishi, which both initiated early development phases whilst waiting more complete requirements.

Specification ''12-shi'' was sent to Nakajima and Mitsubishi, which both initiated early development phases whilst waiting more complete requirements.
Assessing the performance and experiences of the then service-fighter A5M, the IJN's final requirements were for the fighter to reach speeds of 600km/h and climb to 3km in 3.5 minutes while being able to operate for as much as 6-8 hours at cruise with drop-tanks. Equipment was to include a complete radio and armament of twin 20mm cannons plus twin 7.7mm machine guns as well as 60kg of bombs. Maneuverability was to be at least equal to the A5M with a wingspan less than 12m so that it could be fielded on aircraft carriers. On top of those lofty specifications, the ''Type 12'' had to use available engines, a significant limitation.

The A6M1 prototype, powered by a 780hp Mitsubishi ''Zuisei 13 ''engine, passed its testing in a remarkably short period and was ordered into service as the A6M1. Shortly after, the A6M2 incorporated an engine change suggested by the Navy to the 700hp Nakajima ''Sakae 12. ''The new prototype so greatly surpassed the original specifications that 15 units were sent to battle in China, where they were untouched by planes that troubled the A5M. These results led the Navy to immediately order the A6M2 into production as the Type 0 Model 11.

One of the most advanced aircraft of its time, the A6M2 Zero was lighter and more manueverable thanks to its aggressive weight-reduction and thus boasted the longest range of any single engined fighter in the war. It could maintain stable flight well below 110km/h, allowing it to out-turn any Allied fighter of the time. Reports of its performance eventually reached the United States, where they were dismissed as impossible. The A6M2 Type 0 Model 21 in particular introduced folding wingtips so that the plane could better fit onto aircraft carriers, as well as improved range. 2,048 Type 0 Model 21s were constructed by Mitsubishi and Nakajima, including 508 trainers by Hitachi and Sasebo.

Compared to contemporary Allied fighters, however, the anorexic Zero-fighter traded ruggedness and pilot-protection for its maneuverability. This was compounded by its lack of self-sealing fuel tanks, which could easily catch fire and explode when shot. Although it could fly a long distance and was difficult to hit, it required little damage to destroy, unlike its opponents.
