From Halopedia, the Halo wiki
Considered to be a ship for protectors and shepherds, Akton-pattern escorts were rare and valued antiquities within the Covenant fleet, having originated from the Fourth Age of Conversion in which the Covenant spread knowledge of their Great Journey to a new species. The Fourth Age of Conversion was also an age of conflict, leading to Akton-pattern escorts being commissioned to provide protection to Covenant merchants and pilgrims from pirates that lurked throughout the empire's space.
Crew and complement
Despite their reputation, Akton-pattern ships were typically manned by shamed warriors who had fallen from grace. Such warriors donned the mantle of protectors and shepherds, in the hopes of restoring their honour.
The Akton came into existence during the Fourth Age of Conversion, to assist in bringing a new race into the Covenant hegemony and providing protection to Covenant merchants and pilgrims from the pirates which lurked imperial space and the greed of zealous ministers seeking to expand their influence and wealth.. The Akton has continued to see service predominantly in the core Covenant space since, and was a less common sight in the crusading fleets which fought in the Human-Covenant War. In the post-war era, Akton-pattern ships continue to attend noble fleets and defend weaker pilgrims and merchants from opportunistic predators.
