Seeing as one Reich is 1000 years, I don't see why the base unit of Aryanness wouldn't be a kilonazi.
Or perhaps its like the Calorie. Just as one Calorie is 1000 calories, one Nazi is 1000 nazis.
but Bismarck has 2200 personel onboard while Graf Zeppelin never have personel onboard but since she is based on akagi probably it contain 1600 personel, then Iowa has 2600 personel so its gonna be 3,8 kilonazis and around 5-6,4 kiloaryan
