Designation: Astrotrain-class Cargo Freighter

The Astrotrain-class of sub-light cargo freighters first entered service in 2007. Designed and built by Boeing, these ships were used to move cargo and equipment to the various bases and colonies within the Earths solar system. Three basic versions were built: The Astrotrain I bulk cargo ship, the Astrotrain II container ship and the Astrotrain III troop/passenger transport. Additional sub-variants did exist, but all were permutations of the three basic configurations. The Astrotrain-class was instrumental in the building of the bases on the Moon and Mars. It could transport 150 metric tons of cargo, anywhere in the Solar System in a reasonable length of time. With over 150 built, this class remained in service well into the late twenties.

  • Names and disposition: Cargo Freighters were officially only given numeric designations
  • Builder: Boeing Commercial Aerospace
  • Number Built: 156
  • Status: No longer in service

Names and disposition:

  • Cargo Freighters were officially only given numeric designations.
  • Constructed at the L-5 Factory Station 2007-2011 and at Station Equality Fully-automated Weapons Factory 2013-2018.

Service History:

  • UN Spacy 2007-2017
  • UEDF Interstellar Transportation Corps 2018-2028

Class and type:

  • Astrotrain I bulk cargo ship
  • Astrotrain II container ship
  • Astrotrain III troop/passenger transport

Ship’s Complement:

  • 5 crew (2 pilots, and 3 payload specialists)


  • Length: 132 meters
  • Height: 94 meters
  • Span: 59 meters
  • Tonnage: 59 metric tons unloaded, 209 metric tons with typical cargo

Propulsion Systems:

  • Main power system: RRG Protoculture-fueled Reflex furnace. The power plant of the Astrotrain-class vessel can deliver up to 124 Terawatts of power, and can operate for thirty minutes at maximum power before overheat initiates auto-shutdown.
  • Maneuvering Thrusters (4): Fusion-Plasma Reaction Thrusters clusters with steerable nozzles.


  • The Reflex furnace could function for about 10 years at normal usage levels before an energizer rebuild is necessary.
  • At full power and with a typical gross weight of 200 metric tons with cargo, the Astrontrain-class vessels can achieve a maximum delta-v of 195 kps at the cruising acceleration of 0.1 gees.
  • Theoretically, an Astrotrain-class ship can make the transit to Mars in just under a week, when Mars is at its closest point to the sun (perihelion) and Earth is at its farthest point (aphelion). At the typical Mars to Earth transit distance of 227 million kilometers, the total time required to make the journey is 27 days.
