Sum Total is a massive support ship in the Preservation Alliance fleet, equipped with module docking capabilities and large-capacity shuttles designed for planetary evacuation operations. Introduced late in the series during the events of System Collapse, it serves primarily as a backup vessel, providing logistical muscle and emergency extraction capacity when the primary ships like the Perihelion are compromised or occupied. While it lacks the narrative centrality of Murderbot's preferred transports, its presence underscores the growing scale of Preservation's interstellar operations and the need for redundancy in the face of corporate threats and environmental disasters. By the end of the known series, Sum Total remains a reliable if largely background asset, symbolizing the infrastructure that allows Murderbot and its allies to operate with greater security across multiple systems.
