Brunt's shuttle was a Ferengi shuttle used by Brunt and Ezri Tigan. Brunt made modifications to the shuttle including its dilithium matrix to maximize its output.
In 2375, Brunt and Ezri brought the shuttle to Terok Nor where Ezri crossed over to another universe to get Quark and Rom to obtain a cloaking device.
The shuttle later rendezvoused with the Regent's flagship to present the cloaking device to Regent Worf. Later, when the ship was disabled and about to be boarded by the ISS Defiant crew, they boarded it to travel back to Terok Nor. (DS9: "The Emperor's New Cloak")
