and civilian use
|Armament:||At least 3 torpedo launchers and 2 phaser emitters|
The Maquis appropriated several of these ships and used them as attack fighters during their insurrection against the Cardassian Union. Prior to 2370, these ships were civilian Federation support couriers not used by Starfleet. In 2370 a couple of such ships led by former Starfleet officer, Lieutenant Commander Calvin Hudson attempted to attack a Cardassian weapons depot on Bryma, but they were engaged by Benjamin Sisko on the USS Rio Grande forcing them to a strategic retreat. (DS9: "The Maquis, Part II"; TNG: "Preemptive Strike")
Large numbers of these ships were used by Starfleet in the Dominion War. During Operation Return, eight successive waves of fighters were sent to attack the Cardassian ships of a Dominion fleet, hoping to provoke them into breaking formation and creating an opening for the Federation fleet. (DS9: "Sacrifice of Angels")
The attack fighter was capable of carrying an impressive arsenal. When used by Starfleet in 2374, the ships had several forward torpedo launchers and at least one phaser bank with two forward emitters.
When used by the Maquis in 2370, the fighters were armed with whatever weapons were available. Pygorian weapons, including photon torpedoes, pulse cannons, ship-mounted high-energy disruptors and particle accelerators were among the weapons used when an attack was planned at a weapons depot on the Bryma colony. (DS9: "The Maquis, Part II")

- VOY: (all appearances from display graphics, referenced as an "Academy flight trainer")
The fighter cockpit interior, seen in "The Maquis, Part II", was a modification of the Type 15 shuttlepod set. It was reused later from DS9: "The Search, Part I" onwards to represent the Type 18 shuttlepod cockpit.
In the script of "The Maquis, Part II", the phasers used by the Maquis attack fighter are identified as the pulse cannons mentioned earlier in dialogue.  The initial phaser blasts in the episode however seems like regular phaser fire from the extended bank under the nose of the ship. Photon torpedoes are seen being fired from the tube at the nose of the ship. When the torpedo tubes are damaged, the fighter opens fire with pulse cannon phasers from two wing mounted banks that are not visible on the model.
Visual effects in "Preemptive Strike" show phaser fire pulses coming from the wings, where there are three visible tubes on each wing. Phaser fire is also seen coming from the front ends of the embedded warp nacelles. These banks seem to be targetable, instead of firing straight ahead like the Pygorian pulse cannons in "The Maquis, Part II."
The script of "Sacrifice of Angels" states that the attack fighters were firing a barrage of quantum torpedoes when attacking the Dominion lines.  The effects used for the phasers and quantum torpedoes of the fighters in this episode were not what is normally associated with these Starfleet weapons. The torpedo launchers were mounted on the wings and on the nose of the ship. In some shots, the wing torpedoes seem to be launched from the same spot where the pulse cannons were located in "The Maquis, Part II." In others, they seem to be coming from the three small visible tubes on each of the wings. These tubes would seem to be much too small to launch full-sized torpedoes.
In one shot of "Sacrifice of Angels," one of the fighters is seen firing a bluish-white beam from the one of the two forward phaser emitters, on the extended phaser bank, under the nose of the ship. When a fighter fired the phaser from the same location in "What You Leave Behind," the regular Starfleet phaser effect was used.
