Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

History

Main article: History of the A7M

In late 1940, Just after the A6M started entering its production phase, the navy requested Mitsubishi to start development of a direct successor by 1941, but due engine choice for a high-output compact engine was scarce, and the development team having their hands filled with development of the A6M2 Mod.21 and developing the J2M made Mitsubishi decide to scrap the request.

By 1942 as development of the A6M3 Mod.32 and J2M2 Mod.11 have been finished, the navy once more ordered Mitsubishi and their team to design a direct successor which would be faster and as nimble as the Zero, but as before, engines which would suit the plane were still in development and the team had to design a plane while still having to wait on a viable engine.

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 and a trial flight would be performed on the 6th of May, 1944.

While the wingload was acceptable of 150 kg/m², maneuverability and handling were excellent but the engine was simply underpowered and couldn't meet the speed requirements the Navy were looking for and ended up in a disappointed cancel of the project.

But as Mitsubishi already got a greenlight to use Mitsubishi's home-made engine with the MK9 beforehand, the project sparked interest once more for the Navy with the A7M2.
