Weyoun's attack ship was a Jem'Hadar attack ship commanded by the fourth incarnation of Weyoun in late 2372. Also aboard were Omet'iklan, Toman'torax, Virak'kara and three other Jem'Hadar.
In that year, the Dominion sent the ship to track down a group of renegade Jem'Hadar who had captured an Iconian gateway. Near the Gamma Quadrant terminus of the Bajoran wormhole, the warship was attacked by a civilian transport (which had earlier attacked Deep Space 9) the renegade Jem'Hadar had captured.
The attack disabled Weyoun's ship and left it adrift. Weyoun and the Jem'Hadar were later rescued by the USS Defiant, shortly before the ship's reactor breached. (DS9: "To the Death")
