Well, 航 is an abbreviation for 航空母艦 a.k.a. "aircraft carrier". 航 and 甲 share the same pronunciation "kou", so we wanted to avoid that ambiguity. Also, KanColle uses 甲乙丙 etc. as ordinals, which is why we use ABC notation except in the case of difficulty levels where we just call them by what the represent, hence Hard/Medium/Easy Mode.

Anyway, no need to apologise. Just remember that this template uses the naming conventions as seen on the respective ship's main page. Chitose Chitose Kai Chitose A Chitose Carrier Chitose Carrier Kai Chitose Carrier Kai Ni
