And for those who, like me, had a memory lapse on the Shiden Kai’s Allied code name it was “George.”

From the deep recesses of my memory, I recall reading that when the Ki-84/Frank was tested using 100 octane avgas, its performance easily matched and slightly exceeded the Hellcat, Corsair, and P-51.
The Ki-84 was the most competitive fighter they produced: too few too late. Fast, maneuverable, good climb.
Excellent all-around performance, especially at altitude, to intercept the B-29, which had turbo-superchargers for high-altitude precision daylight bombing.
