Strategy, Tactical, Leadership, and Technology

The Mitsubishi A7M3 was a projected refinement of the A7M2 Reppū ("Strong Gale") designed to optimize performance at higher altitudes and improve firepower. Building upon the promising capabilities of the A7M2, the A7M3 aimed to incorporate a mechanically driven supercharger on the Mitsubishi Ha-43 radial engine, enabling superior climb and speed at altitude while simplifying maintenance compared to the turbocharged systems proposed for other variants. To meet the demands of confronting high-flying U.S. bombers, the A7M3 was also envisioned with increased armament, likely incorporating four or six 20mm Type 99 cannons. While retaining the basic airframe and aerodynamic excellence of the A7M2, the A7M3 would feature reinforced structure, improved high-altitude aerodynamics, and potentially reduced wing loading. Despite its potential, the A7M3 never reached prototype stage due to material shortages, the destruction of the Ha-43 engine production line, and Japan’s deteriorating war situation in late 1944 and early 1945.
