 In late 1944 an earthquake strained the manufacturing of the A7M2 causing only 8 to be built. In early 1945, Allied bombings of Japans mainland lead to the destruction of the A7M plans. This ceased the development of the A7M2, and the plane would never see combat. Only a single A7M2 would be built in 1945 due to allied bombings.

 ==Description==
-The '''Mitsubishi A7M''' is a direct successor over the '''[[A6M (Family)|A6M]]''' in every regard, used by the Imperial Japanese Navy in World War II.
+The '''Mitsubishi A7M''', designated as '''Reppū ({{Annotation|烈風|Strong Wind}})''', was a series of Japanese fighter aircraft designed and built by Mitsubishi Heavy Industries during World War II. The '''A7M''' was intended to replace the '''[[A6M (Family)|A6M]]''' as the Imperial Japanese Navy's main carrier-based fighter. The A7M had a more powerful engine, a larger wing, and improved manoeuvrability and speed than the Zero. However, the A7M faced many technical difficulties and delays, and only a few prototypes were completed before the end of the war.

 ==History==
-Very soon after the [[A6M2 mod. 11|A6M2 mod.11]] started entering the production phase in end-1940 the Japanese Navy already requested Mitsubishi to design a direct successor of the A6M which would be dubbed as the ''16-shi''. But at the time there was no viable high-output as calculations by Jiro Horikoshi's development team who designed the [[A6M (Family)|A6M]], suggested that in order to have a climb rate and top speed needed by the Navy they would have to use a minimum of 2,000hp engine. This proved to be an exceptional challenge as the two engines which theoretically could develop this power were still under development and besides that  Horikoshi's team were still occupied with engineering the [[A6M2|A6M2 mod.21]] and designing the ''14-shi'' interceptor (which would later be known in service as the [[J2M (Family)|J2M]]), for these reasons Mitsubishi put the plans for a Zero-successor on hold in January of 1941.

 ===Development===
 In April of 1942, development of the [[A6M3|A6M3 mod.32]] and [[J2M2|J2M2 mod.11]] were finished and the navy once again tasked Mitsubishi and Horikoshi's team to design a new zero successor dubbed this time as the ''17-shi Ko''. The Navy requirements for the 17-shi were as followed:

    '''Maneuverability''' ≥ A6M3
-As before, one of the main hurdles was engine selection. To meet the specifications the engine would need to produce at least 2,000 hp (1,500 kW), which narrowed choices down to Nakajima's NK9 "Homare" (Ha-45), or Mitsubishi's MK9 (Ha-43); both engines still being under development. These engines were based on 14-cylinder (Nakajima NK1 "Sakae" (Ha-25) and Mitsubishi MK8 "Kinsei" (Ha-33), respectively) engines converted to 18-cylinder powerplants. The early NK9 had less output but was already approved by the Navy for use on the  [[P1Y1 mod. 11|Yokosuka P1Y Ginga]], while the larger MK9 promised more horsepower.

-With the larger, more powerful engine compared to the A6M's, wing loading became an issue. The Navy requested at most 150 kg/m², but wanted 130 kg/m² which complicated design considerations further. With the NK9 it could achieve 150 kg/m2, but with the less power it would not meet the specifications for maximum speed. With the MK9's 2,200 hp (1,600 kW) the engineers concluded it could fulfill the requirements; however, production of the MK9 was delayed compared to the NK9, and the Japanese Navy instructed Mitsubishi to use the NK9's 2,000 hp (1,500 kW).

-Work on the 17-Shi was further delayed by factories prioritizing [[A6M (Family)|A6M]] and [[G4M1|G4M]] production as well as further work on [[A6M (Family)|A6M]] variants and addressing [[J2M (Family)|J2M]] issues. As a result, the 17-Shi, which became the [[A7M1 (NK9H)|A7M1]], officially flew for the first time on 6 May 1944, four years after development started. The aircraft demonstrated excellent handling and maneuverability, but was underpowered as Mitsubishi engineers feared, and with a top speed similar to the [[A6M5|A6M5 mod.52]]. It was a disappointment, and the Navy ordered development to stop on 30 July 1944.

-But previously Mitsubishi obtained permission for development to continue using the Ha-43 engine, Saburo Sakai test-flighted with Ha-43 on 13 October 1944 and after the flight test, Sakai was extremely impressed with the [[A7M2]]. The [[A7M2]] now achieved a top speed of {{Annotation|339 kn|628 km/h; 390 mph}}, while climb and other areas of performance surpassed the Zero, leading the Navy to change its mind and adopt the ordered cancel. The [[A7M2]] was also equipped with automatic combat flaps, used earlier on the Kawanishi [[N1K (Family)|N1K-J]], significantly improving maneuverability.
