The Cohort-III grew directly out of the design effort of the Cohort-II. With the wide proliferation of space craft in the Sol system a tactical upgrade was viewed as nessecary. Where the Cohort-II is well armed, the Cohort-III might be termed over armed. All of the torpedo emplacements were increased by half and they were all fitted with individual targeting arrays. The phasers were significantly strengthened as well, and all general systems were upgraded as well.
