I don't see how this is related to Kantai Collection and have also checked pixiv. The closest series to this post is Upotte, as a related tag suggests. Thus, I'm removing the tag.

Correct, this is actually a Mecha Musume of the Estovakian CFA-44 Nosferatu from Ace Combat 6.
I can also confirm that the other aircraft are MQ-90 QUOX from Ace Combat Infinity and the Estovakian Malgebolge UCAVs.
