Meanwhile - slightly updated stats for Navy fighters (mostly reduces bombloads) and Army fighters. Necessary notes about what is going on with these statblocks - the last model of Ki-81 is fitted with Mitsubishi Ha-43 engine, giving it stats close to that of late production Ki-84s, and it is presumed that the competition for the high-altitude fighter is fair in this alternative, so Tachikawa begins with its second design, but it is rushed to production, before its intended turbosupercharger is perfected, therefore two versions. The engine is Ha-214, the late (experimental IRL) version of Mitsubishi Ha-42.
As another note, I wonder, what caused praise for Ki-100? Looking at its characteristics, its very underwhelming game stats (basically fit for 1943, but in 1945) apparently reflect reality quite well, except maybe in performance at high altitudes. I can understand giving it a credit for reliability, but I've seen several quotes from its testers that rated it far higher than Ki-84 in performance (combat data for Ki-100 is very limited, IIRC only one engagement with Hellcats that ended 2:2). Strange. Maybe quality of Ki-84 degraded that far by second half of 1945, or maybe there were some nuances of their flight characteristics that aren't reflected by numbers.
