Vengeance-class Super Star Destroyer

The Imperium
The Imperium was a Vengeance-class Super Star Destroyer that was used between 34 ABY-58 ABY. It began construction in 5 BBY as a flagship for Grand Moff Tarkin but Palpatine didn’t want to waste resources so he continued the project. After it was completed in 34 ABY Emperor Leo Fett took the ship as his own personal flagship. It was destroyed after a rebel ship pulled a Holdo Manuever which caused it to crash down onto the Imperial Palace in the Battle of Coruscant.
