The Galaxy has seen a time of peace during the Pellaeon–Gavrisom Treaty. However something long forgotten stirs in the underworld, and threatens the peace everyone has worked so hard to achieve. Will you fight with the New Republic who has been betrayed from within? Will you fight with the Imperial Remnant who has been duped into a war they did not want? Will you side with the Mandalorians, who feel that they must bring peace to a galaxy dominated by force users? Or will you side with a Dark force rising, taking forces from within major governments? The choice is yours commander.
Another ISD class that was seen in a few EU comics, and was subsequently destroyed by a large Rebel fleet. Larger than the standard ISD, but lacking the ventral hangar. Wanna try and guess what class it is?
Model Cred goes to eville_jedi
It resembles a Titan or Allegiance Class SD...
Ding ding ding! It's an Allegiance Class!
Saw the other picture first so I didn't know someone answered it already.
