TIV Z590/1 was the designation of the Traffic Interdiction Vessel used by Omega Squad during a special operations mission to the Corellian-Perlemian hyperspace intersection. Externally, the TIV looked like an anonymous battered utility shuttle. However, it was in fact a compact assault platform armed with at least a dozen weapon systems.
The unmarked, non-military vessel was destroyed by the civilian freighter Nova Crystal after being mistaken for a pirate ship. The ship's clone trooper pilot, CT-1127/549 nicknamed "Sicko", was killed in the incident. Due to the secrecy of Omega Squad's mission, the true nature of the vessel was never released and the skipper of the Nova Crystal was regarded as a hero for his actions by the Perlemian Traffic Control.
