-The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} Japanese fighter {{Battle-rating}}. It was introduced in [[Update 1.53 "Firestorm"]].
+The '''A7M1 (NK9H)''', designated as '''17-Shi, Reppū ({{Annotation|十七試, 烈風|1942-Plan, Strong Wind}})''', was a pre-production model of the Reppū, the [[A6M]] ''Zero'' successor. It was developed since late 1940, but faced many delays due to the Navy's high expectations and the lack of powerful engines. Mitsubishi tried to make their own engine, the Ha-43 (MK9), but it was not ready until 1944. The Navy asked Mitsubishi to use Nakajima's Ha-45 Homare (NK9) engine in 1943 instead, but this also took time because of Mitsubishi's prioritization to existing production lines. The A7M1 finally flew in May 1944, and showed great handling and maneuverability, but it was still underpowered with the 2,000 hp engine. The Navy cancelled the order for the Reppū. (Mitsubishi continued development for the MK9 engine for the [[A7M2]], which achieved 2,200 hp and navy approval.)
-The A7M1 Reppu is the prototype version of the A7M2 in the tech tree fitted with a NK9H engine. In game this fighter is the definition of a  "jack of all trades." It has excellent energy retention, amazing turn rate, and decent  speed. These traits makes the A7M1 an excellent hybrid between a turn fighter and energy fighter. It can fit almost any playstyle because of it.

 ;;High altitude fighting
-Turn fighting at high altitude is rather difficult since, the higher you go, the less air pressure there is. This means there will be less air to lift your plane when doing a hard turn compared to sea level, meaning the A7M1 will not be able to turn as fast as you do at sea level. This should be taken into consideration since most of the planes at high altitudes (4+ km) often have superchargers or turbochargers ([[Wyvern S4]] for example) and will make an easy prey out of you, as you do not maintain the same energy nor speed they maintain.

-The A7M1 ''Reppu'' is a relatively heavy plane but still performs very similar to an [[A6M (Family)|A6M ''Zero'']] with the increased performance thanks to its high output engine. This engine however won't be the best outfitted on the A7M platform and a better can be found in the tech tree as the [[A7M2]] which boasts a Ha-43 engine with 200 hp extra.

 The A7M1 that takes the best of the [[A6M (Family)|A6M]] and does it better also translates it in aerial combat. With its higher output, very similar manoeuvrability and higher rip-speeds, it can engage in all playstyles; whether the situation calls for it the A7M can either turn fight, Boom-&-Zoom, energy fight and others. Yet even with its NK9H engine, it is sometimes tricky to maintaining energy fights with enemies like the [[F6F-5]], [[P-51 (Family)|P-51]], etc.

-Only couple of planes like Spitfires can be a challenging opponent at low altitudes, mainly because most planes will lose energy when fighting with the A7M1 at low altitudes when the A7M1 is able to outturn and be on their tail in couple seconds. The 13 mm and 20 mm armaments combined are very deadly and will tear down a plane in a good placed burst. Aim for center of mass when turn fighting, and tail when tailing, especially the elevators.

-The drawbacks from high altitude does not stop the A7M1 from fighting in the clouds. One of the easiest targets for the A7M1 are bombers. They are big, have big wingspans and are often slow (unless they are dive bombers or strike fighters). They can be easily destroyed with the 13 mm and 20 mm armaments due to their sheer calibre and destructive ammunition. When engaging a bomber, aim for the engines or wings. With the right belts equipped, a few well placed shots the bombers will catch fire or even shred the wings.

-As development of the A7M platform came to an end, the last set piece and main problem of the A7M development, being the engine, led to the first prototype to make use of the Nakajima NK9 "Homare". This singular plane would be the first A7M and respectively would become the [[A7M1 (NK9H)|A7M1]] and a trial flight would be performed on the 6th of May, 1944.
