Nador's starship

From Memory Alpha, the free Star Trek reference

Nador's starship was a Cardassian Galor-class starship in several of the parallel universes encountered by Worf in 2370, of which Gul Nador was commanding officer.

In some of those realities, Nador had used this vessel to tamper with the Argus Array, and attack the USS Enterprise-D. (TNG: "Parallels")

It was never established whether or not Nador or his vessel existed in the "regular" reality of Star Trek's universe.
