The first prototype G5N1 made its maiden flight on 10 April 1941. Overall performance proved disappointingly poor however, due to a combination of excessive weight, the unreliablity of the Mamoru engines and the complexity of the design. Only three more prototypes were completed. In an attempt to salvage the project, two additional airframes were fitted with 1,530 hp Mitsubishi MK4B 12 "Kasei" engines and redesignated G5N2s. Although the Mitsubishi engines were more reliable than the original Mamoru 11s, the aircraft was now even more hopelessly underpowered and further development of the type was halted. |

The first prototype G5N1 made its maiden flight on 10 April 1941. Overall performance proved disappointingly poor however, due to a combination of excessive weight, the unreliablity of the Mamoru engines and the complexity of the design. Only three more prototypes were completed. In an attempt to salvage the project, two additional airframes were fitted with 1,530 hp Mitsubishi MK4B 12 "Kasei" engines and redesignated G5N2s. Although the Mitsubishi engines were more reliable than the original Mamoru 11s, the aircraft was now even more hopelessly underpowered and further development of the type was halted.
