The Grace combined the carrying capacity of the Kate with the performance of the Zero. It might have been troublesome had it gone into production before the Allies gained control of the air and destroyed the Japanese carrier fleet. Like the U.S. TBF Avenger, it was capable of dive bombing as well as torpedo bombing.

Few were produced and fewer saw combat. Production was interrupted by Allied strategic bombing and by an earthquake in May 1945 that destroyed the Funakuta factory.
