Jem'Hadar fighter (25th century)

The Jem'Hadar fighter was a class of small craft fielded by the Dominion from the late 24th century to the early 25th century. 

History
Several squadrons of these ships were part of the Dominion fleet sent to reinforce Deep Space 9 in early 2374 under the command of Loriss and First Kar'ukan. The Prophets diverted this fleet forward in time, causing it to arrive in 2409 instead, whereupon they captured the station from the Federation.

A squadron of these fighters was holographically duplicated for a training exercise organized by Starfleet forces at their temporary base of operations in Hathon on Bajor. 

A number of these attempted to stop an Alpha Quadrant shuttlecraft from sabotaging Deep Space 9's sensor arrays. They tried to defend workbees repairing the sensors but were unsuccessful. 

Background
That this fighter class was in service in the 24th century is a deduction based on the point of origin of Kar'ukan's fleet. It did not appear in any other Star Trek series.
