These outposts were used as fixed defense installations along the Federation/Romulan borders. Impressive fortification for the period, Zha Mortas Outposts are able of easily repelling most enemy task forces.

In the Klingon navy, command of these outposts is not sought after. The duty is considered to be demeaning as it doesn't allow many chances, if any, for glory in combat. The commanders of these bases have a great deal of power in their hands nevertheless. The bases are usually accompanied by repair facilities and other much needed diversions for front line units, all under the base commander's jurisdiction. The name is a translation of the Klingon zha mortas.
