Terran raider fighting off the Regent's forces

Bashir's raider while evading photon torpedos fired by the regent's forces

Bashir's raider was a Terran raider used by the Terran Rebellion in 2372. It participated in the Battle of Terok Nor and was operated by Julian Bashir and Jadzia Dax.

After all other raiders of the Rebellion had been destroyed, Bashir and Dax took this last remaining vessel in order to distract the alliance fleet under Regent Worf by generating warp shadows in order to fool the alliance's sensors to see multiple vessels instead of just one.

Afterwards, Bashir took the raider back to Terok Nor in order to aid the newly-completed ISS Defiant against the regent's flagship. Together the raider and Defiant caused crippling damage to the regent's flagship, prompting the regent to choose to retreat giving the rebels victory. (DS9: "Shattered Mirror")
