The Ki-73 was an earlier attempt to meet the same specification for a long-range escort fighter that was later developed as the Ki-83. The Ki-73, however, had a single-engine configuration as opposed the later Ki-83's twin engines. When development problems with the 2,600 hp Mitsubishi  Ha-203-II engine caused a delay in the program the Ki-73 project was abandoned, and the Ki-83 project began as its replacement. However, based upon captured documents the Allies believed that the Ki-73 was about to enter service with the Japanese Army, and gave it the Allied codename of "Steve".
