Having seen Return of the Jedi our Stormtrooper decided that leaving that planet of Endor and heading back to Tatooine was a good idea. So he jumped on our next gift a Star Destroyer and left at warp speed.
A Star Destroyer was a powerful, dagger-shaped line of capital ships that were put into use by both the Galactic Republic and Empire, as well as the First Order.
Notable examples of Star Destroyers include the Imperial-class Star Destroyer and its predecessor the Venator-class Star Destroyer. [SOURCE]
Dagger shaped? Try pizza shaped.
