The Shea'p-pattern Sweeping Turret[2] (UNSC Type classification: Type-58 Directed Energy Support Weapon, T-58 DESW)[1], simply known as the plasma cannon or plasma turret, is a portable support turret that was in service with both the Swords of Sanghelios and Jul 'Mdama's Covenant during the Blooding Years, as well as the Banished during the Battle for Zeta Halo. In addition to being used as a stationary and portable turret, it was also used as secondary weapons for the Mikpramu-pattern Phantom, Kemu-pattern Wraith, Banished Phantom, and Eklon'Dal Workshop Wraith.[3][5] It replaces the previous Pek-pattern plasma cannon.


The T-58 DESW exchanges San'Shyuum refinement and grace seen in earlier models for Sangheili simplicity and ease of manufacture. Temperamental and heavy, the desperate need for these heavy weapons by the warring factions outweighs any concerns about their quality.[1]
