I don't know if the "Viper" in that Caprica episode was meant to represent an aircraft used by Clonial Forces or whether it was meant to only represent a simulated aircraft in their V-World, a bit like the weird fighters in a PC based computer game that was around about a decade ago (I can't remember its name, never having played it, but it involved airships and odd fighters with strange engine and flight surface configurations, all acting as aerial pirates if I recall it correctly). In fact, I suspect that game was the inspiration behind the aircraft and airships in the V-World Caprica City, too.
