The Mjern-pattern support ship, designated the DSC-class agricultural support ship, is the primary model of auxiliary support ship that was manufactured and deployed by the Covenant Empire.

Constructed with a unique webbed, flat hull design, the Mjern-pattern is an anomaly within the Covenant fleet. It is dedicated support vessel with little in the way of combat capabilities, relying on their embarked strikecraft squadrons and escort fleet for protection. In exchange, they use their two large agricultural domes, and an assortment of tertiary assembly forges to provide a wide range of supplies to the personnel of the fleet. In battle, a sophisticated array of proselytziation relays can overcome any localised jamming source, maintaining fleet cohesion so long as the flagship is intact.

The Mjern-pattern support ship has been in use since the Fourth Age of Reclamation, and has persisted through the centuries thanks to its modular functionality. Like all logistical craft, they were maintained by the Ministries of Abnegation, Etiology, and Preparation; government departments that do not operate within the normal Sangheili chain of command. Participating in every conflict the Covenant was involved with, although the entire class disappeared following the exile of the San'Shyuum.
