The JAX-12 fighter was a jet-powered fighter used by Sinyan forces during the Sinyan Civil War and Cruentusian War. The craft first saw use by both factions during the Sinyan Civil War, however, due to their cost of maintainance, they were not used in large numbers and were never mass-produced during the war. A small number of these craft were used by Sinyan militias against the Srav Federation, but were easily bested by their more modern rivals. However, following the Sinyan's victory over the Sravs, more modern versions of the craft were built for use in the Sinya Defense Force. Although still far behind other craft in speed and agility, the newer JAX-12 models could carry heavy armaments making them effective fighter-bombers.
