QIj'tagh class

The QIj'tagh class was a type of heavy escort fielded by the Klingon Empire during the 24th century. 

The QIj'tagh consisted of a main hull that expanded dorsally, which gave it a two-tiered appearance when viewed from the side. On the upper dorsal area of the main hull was a axehead-shaped section that contained the bridge module. The ship's wing pylons curve forward and downwards, with the ship's warp nacelles attached to the ventral side of the pylons where the wing meets the main hull.

The class was heavy service during the Dominion War where it mainly did convoy escort duties. 77% of these convoys completed their missions and provided an additional 14% boost to supplies along the front lines.
