Small Bajoran fighter from the resistance era, flown by Kira and Dax to carry proof of Cardassian meddling to Bajor in 2370.
Sub-impulse raiders were small Bajoran fighters dating from the resistance against the Cardassian occupation. Unable to reach warp, they were robust craft for short-range combat, and a number of them had been stored on one of Bajor's moons.
In The Siege, Kira and Jadzia Dax were dropped on that moon, got one of the raiders working and flew it toward Bajor with evidence of Cardassian support for the Circle's coup. Bajoran fighters shot it down, but Kira and Dax survived the crash landing and went on to reach the Chamber of Ministers.
