Leviathan (Interdictor-class cruiser)

Leviathan was the flagship of Darth Malak's Sith fleet 4000 years prior to the Battle of Yavin.

As with the other capital ships of the Sith fleet, Leviathan was originally a Republic ship that fell into Sith hands after the battle at Malachor V. Apparently a distant technological ancestor of the later Star Destroyers, Leviathan was one of many similarly designed ships commissioned by the Republic for the Mandalorian Wars.

Leviathan was an 600 meter long interdictor cruiser, capable of wrenching ships out of hyperspace with the use of its four gigantic gravity-well projectors. While primitive by modern standards, it was the pinnacle of interdictor technology in its time. It was also equipped with 20 quad laser cannons, a tractor beam projector, two turbolaser batteries and two ion cannons. Under Saul Karath's command, Leviathan housed two squadrons of Sith fighters.

After the theft of Leviathan, Ravager and many other 'proto-Star Destroyers', the Republic abandoned the design, and used capital ships more aesthetically in line with the peacful ages of the Republic, such as those prior to the Clone Wars.
