The Decimator is the flagship of the Scarran fleet and personal warship of Sith Lord Darth Staleek during the First War. Faster than both the Scarran dreadnought and stryker, the Decimator is also heavily armed including missiles which appeared to be armed with nuclear warheads. It has also shown to have formidable defenses, able to withstand concentrated fire from a Peacekeeper Command Carrier. It does have, however, several vulnerable locations near its aft section, making it possible for the ship to be disabled with as few as three precise hits.
The Decimator sports a sleek, aggressive appearance, complemented by three blade-like protusions that surround the rest of the forward section of the craft. While it is dwarfed by the Peacekeeper Command Carrier, the Scarran dreadnought, the Mon Calamari Cruiser, the Minbari Sharlin-class, the Imperial-I Stardestroyer, Starfleet Galaxy-class, the Decimator can hold its own in an engagement.
