Six Jupiter-1s on the UNSC Spirit of Fire.

The Jupiter-1 is a type of starship maneuvering engine created by Orphios Energy Systems.[1]

The destroyer UNSC Calcutta was fitted with at least six Jupiter-1s, before it was scuttled in 2530. Six of these were later installed on the UNSC Spirit of Fire, after the Calcutta was scuttled.[2][1]
