The Cloakshape from Dark Empire. I loath the EU, and Dark Empire in particular, but I really like this ship. It's shown here at the listed fifteen meters, assuming that figure is meant to represent the ship with it's tail on even though the tail is explicitly stated as being an aftermarket add-on. Were the ship itself to be fifteen meters long, it would be absolutely vast. On the presented scale the main fighter is actually 9.2 meters.
