- "This is the last voyage of the Harbinger. So Let's make it a memorable one."
- ―Luke Skywalker to Han Solo and Leia Organa
The Harbinger was 1,600 meters long, the standard length for an Imperial-class Star Destroyer. As such, it was initially armed with turbolaser batteries, ion cannons, and several tractor beam projectors. Before it was hijacked, the Harbinger was upgraded with the removal of its tractor beam targeting array with a communications tower.
