If you're referring to the
apocryphal carrier class mentioned in the German-only novel
En Passant, like I wrote on Sarna it seems functionally and historically identical to the
New Syrtis class - which was written into canon much later and presumably without knowledge of the German novel which isn't regarded as canonical anyways.
My head-canon says the
Kitty Hawk class was a forerunner/prototype of the
New Syrtis class; they're basically the same class.
