COMMENT: The Mitsubishi G7M was basically a derivative of the most famous Mitsubishi G4M Navy attack bomber. It was originally designed as a long range, strategic bomber able to carry a greater payload over a longer distance. To meet these requirements a four-engine design was favored.
When detailed information about the German Heinkel He 177 became available – a four-engine heavy bomber with dive-bombing capability, powered by two H-engines twinned together in one nacelle on each side thus reducing drag – the G7M design was changed in that manner. Germany promised to deliver the needed machinery to produce the H-engines under license. Other features of the Heinkel design were incorporated, too, such as the glazed nose, four-blade propellers, and a similar tail plane. In contrast the Mitsubishi design used a tricycle landing gear system. The ongoing war situation made it impossible to import the German H-engines as well as the tools for production and the design was changed again to a four-engine bomber but the end of the hostilities stopped all further work (Ref.: 24).
