Lego Star Wars 10030 Imperial Star Destroyer Ultimate Collectors Series was a capital ship used by the Galactic Empire. It is also a term used to descibe heavily armed warships, capable of destroying entire star systems. It did not necessarily indicate a destroyer type vessel. This specific model, however, is the Imperial I-class Star Destoyer, the same model as the one that captured the Rebel Blockade Runner, Tantive IV. They were armed with six dual heavy turbolaser turrets, two dual heavy ion cannon turrets, two quad heavy turbolasers, three triple medium turbolasers, two medium turbolasers, sixty Taim and Bak XX-9 heavy turbolasers, sixty Borstel NK-7 ion cannons, and ten Phylon Q7 tractor beam projectors.
