The CX-133 was developed and mass produced by Koros Spaceworks as a cheap, light-weight fighter. Capable of ramming attacks combined with swarm tactics, the volatile fuel and munitions storage was capable of rendering massive damage to any potential target.
These fighters were often carried on board Supremacy-class attack ships. In the Battle of Koros Major, the CX-133 were used to make suicide attacks on the Republic Navy, seriously damaging the command ship Reliance I. In the Second Battle of Empress Teta, they defended Koros Major against an Onderon warbeast transport and four Jedi one-man fighters which assaulted the Iron Citadel of the Krath in an attempt to rescue Ulic Qel-Droma. During the Battle of Foerost, they were used in the attack on the Foerost Shipyards.
