Bajoran interceptors, also known as Bajoran impulse ships, were sublight interceptors used by the Bajoran Militia, that were lightly armed with two phaser emitters. The vessels also had towing facilities. (DS9: "The Siege", "Sanctuary"; TNG: "Preemptive Strike")
These vessels were readily used in orbit of Bajor to intercept and protect the planet from unwelcome incoming vessels, as well as used by the Maquis in protecting their colonial interests. (DS9: "Sanctuary"; TNG: "Preemptive Strike")
In 2370, two Bajoran interceptors, operated by Bajorans loyal to the Alliance for Global Unity, pursued a Bajoran raider, piloted by Kira Nerys and Jadzia Dax, in attempt to intercept the raider before Kira and Dax could reach the Bajoran Provisional Government to reveal the truth behind the coup. While pursuing the raider, the interceptors were forced into Bajor's atmosphere, where one of the ships was shot down by the raider, before the second interceptor was able to bring down its objective. (DS9: "The Siege")
Later that year, General Hazar ordered Interceptor One to stop a Skrreean ship from landing on Bajor. Hazar countermanded the order on being informed that the vessel was piloted by a youth but Interceptor One's phasers ignited radiation that had been leaking, destroying the Skrreean ship and killing its three occupants. (DS9: "Sanctuary")

In "Preemptive Strike", the Maquis squadron containing Bajoran interceptors among other ships was said to consist of Federation starships emitting Federation warp signatures. This suggests some of these interceptors were owned by Federation colonists and were possibly refitted with warp drives.
The Bajoran Interceptor was designed by Jim Martin as one of his first assignments on Deep Space Nine after having been promoted to production illustrator, or as he recalled, "I remember that one! One of the first things I worked on when I was illustrating on season 2. I think we did a bajoran fighter as well for that episode." wbm The model, its sleek, gracious lines betraying some of Martin's Star Wars influences was built at Tony Meininger's Brazil-Fabrication & Design. wbm Making its debut in DS9: "The Siege", the model, measuring 18 x 27 inches, was mostly seen as a pair of deep background vessels circling the station.
It was common practice for the production department to redesignate, redress, and/or rebuild lesser known studio models, both physical and later on, CGI models as well, out of time and cost considerations to appear as ships belonging to various alien races all over the Trek-universe, the Merchantman, Batris, Mondor, and Jovis being prime examples. This studio model was one of the few exceptions to the rule, once designated Bajoran, it was never modified (save for a paint touch-up) nor did it change affiliation during its lifespan, it being operated by the Maquis or in the mirror universe notwithstanding.
As part of one of the last batches of existing studio models being transformed into CGI models, a CGI version was built at Digital Muse, which made its first and last appearance in DS9: "Shadows and Symbols", later appearances being stock footage of the physical model.wbm Curiously, screencap analysis suggests that both models have been used in near identical shots in the episode. 
The physical model, known as Lot 489, being part of the 40 Years of Star Trek: The Collection auction, estimated at US$3,000-$5,000, was eventually sold on 6 October 2006 with a winning bid of US$4,500 (5,400 including buyer's premium) to American collector Adam Schneider. It was one the few studio models that actually sold within its estimate, as the majority of them were sold well above theirs.  A foam core camera test model sold as Lot 7507 for US$168.15 in a July 2008 It's A Wrap! sale and auction.
