Editing Propulsion pod

{{Status|Canon}}

'''Propulsion pods''' are a form of [[tug]] used to give [[human]] space vehicles maneuvering capabilities and the ability to enter [[Slipstream space]].{{Ref/Book|Id=ch23|Book=Halo: Contact Harvest|Page=23}} They are an integral component of [[DCS light freighter]]s, which, without a propulsion pod attached, are simply cargo containers lacking any maneuvering systems or a [[Shaw-Fujikawa Translight Engine|slipspace drive]].{{Ref/Book|Id=ch67|Book=Halo: Contact Harvest|Page=67}} In this respect, their function is similar to tugboats used to push supertankers out to sea. They connect the rear of the vehicle with a powerful magnetic coupling and are bulbous, around 1/10th the size of a DCS freighter cargo container.{{Ref/Reuse|ch23}} Propulsion pods are extremely utilitarian in design; most of their interior components are exposed, apart from the slipspace drive, which is encased in a protective cowling.{{Ref/Book|Book=Halo: Contact Harvest|Page=65}}

Propulsion pod-equipped freighters were the most common type of craft used by the [[UNSC Department of Commercial Shipping]] to ferry supplies and agricultural produce to and from the planet [[Harvest]] by [[2524]].{{Ref/Reuse|ch67}} They were also used during the escape from Harvest. After the [[First Battle of Harvest|first meeting]] with the [[Covenant Empire|Covenant]] went sour, [[Sif]], following a plan by [[Jilan al-Cygni]], moved hundreds of propulsion pods from the [[Tiara]] out into space, to coordinate weeks and months ahead of [[Harvest]], along its orbital path several days before the Covenant warship, ''[[Rapid Conversion]]'' arrived.{{Ref/Book|Book=Halo: Contact Harvest|Page=278-279}}

When the Covenant began attacking Harvest, they fled from surrounding cities to Utgard, the capital of Harvest and the location of the [[space elevator]] depot. As war waged around them, over 250,000 humans managed to escape the planet by packing into 236 freight containers which where loaded into the space elevators along with two "grease buckets", maintenance containers that carried [[Avery Junior Johnson|Johnson]]'s and al-Cygni's [[Harvest militia|militia]] men. The freight containers that survived, along with the two "grease buckets", then traveled the length of the space elevator strands, passing the Tiara and jettisoned out into space, where they coupled with the propulsion pods, allowing them to enter slipspace and escape from the Covenant.{{Ref/Book|Book=Halo: Contact Harvest|Page=352}}
