A small, lightly armed impulse-driven patrol ship used by the Bajoran Militia to guard the space around Bajor, seen in The Siege, Sanctuary and the blockade of Derna in Shadows and Symbols.
Bajoran interceptors are the small patrol craft of the Bajoran Militia in Star Trek: Deep Space Nine. They have impulse engines only and carry a pair of phasers, and are often seen in the background circling the station.
In The Siege two interceptors loyal to the Circle chase the old raider in which Kira and Dax are carrying proof of Cardassian involvement in the coup. One is shot down and the other brings the raider down. In Sanctuary an interceptor ordered to stop a Skrreean ship from landing on Bajor fires on it, igniting a radiation leak and killing the young crew.
The same design is flown by the Maquis in The Next Generation episode Preemptive Strike. In Shadows and Symbols Kira leads a handful of the ships in a blockade of the moon Derna against Romulan warbirds that hopelessly outgun them.
