[...] They are 甲型, 乙型, 丙型, and 丁型駆逐艦, which are the official names for Kagerou-class, Akizuki-class, Shimakaze-class, and Matsu-class, respectively. This is why C is skipped. Type C destroyer represents heavy-torpedo setup like Shimakaze. If a DD gets a K2C she would have a high torp stat. Asashio getting a K2D means she'll have poor firepower and poor torpedo, and will have some sort of speciality towards transport and escort duties.
