The Bajoran Interceptor:  From the great web site Memory Alpha...

"Bajoran interceptors (or Bajoran impulse ships) were sublight interceptors used by the Bajoran Militia, that were lightly armed with two phaser emitters.  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.  In 2375, interceptors were used in the Bajoran blockade of Derna against the Romulans, despite being severely outmatched by the incoming Warbirds they faced." 

Thie screencap is from Deep Space 9:  Shadows and Symbols.  A flotilla of ships is defending against the Romulans.  Kira and Odo are in the lead, "hero" ship.  Note that several others are shown in background.

The ship was first introduced late in the run of Star Trek: The Next Generation, as a maquis ship.  It then made over 20 appearances in Deep Space 9, mostly guarding the station in later seasons.

It was Smiley's (O'Brien's) ship in the mirror universe... here's a picture from DS9: Through the Looking Glass

And here it is, mounted and relit....
