The [[abyssal ship|abyssal]] version of [[aircraft]] in [[Kantai Collection]]. Unlike the shipgirl aircraft, which tend to be miniature replicas of real [[World War II]]-era [[Imperial Japanese Navy]] aircraft, abyssal aircraft have the alien appearance of [[abyssal ship]]s.  

They usually look triangular from the top, with a black metal skull-like appearance. Underneath, they have cannons sticking out of their "mouths" or have bombs or [[torpedo]]es strapped underneath. Some, notably those launched by [[Northern Ocean Princess]], have a more [[takoyaki]]-like spherical look, and are white with red highlights.

Not to be confused with the spherical and eyeless [[Floating Fortress (kancolle)|]] or [[Escort Fortress (kancolle)|]].
