All ships with the Star Flight attribute need a propulsion system called a Hydrogen Mass Thrust Drive which allows the ship to travel at the speed listed under Star Flight. The Hydrogen MTD provides the forward thrust and the Star Flight provides the method of travel. The Hydrogen MTD can be replaced by a more efficient booster system – represented by the MTD attribute.


All Mass Thrust Drives work by ejecting a stream of matter out of the back of the ship. The denser the matter, the faster the ship can move. Each level of the MTD attribute increases the speed of the ship by 10%. The mass used is generally stored as huge rods of shielded material at the back of the ship. The mass is considered fuel, and needs to be replenished. (Hydrogen doesn't need to be replenished as it can be collected in free space as the ship moves. Thus ships with a hydrogen MTD run cheaper than those with this attribute.)


A level 0 Mass Thrust Drive uses Hydrogen.

A level 1 Mass Thrust Drive uses Carbon Boosters, usually a graphite or diamond rod, but in an emergency a tree trunk will do. Silicon or anything with a density of > 1 g/cm3 is fine.

A level 2 Mass Thrust Drive is a Xenon Drive. Iron, Tin, Titanium, & Xenon are all good. (density > 4 g/cm3)

A level 3 Mass Thrust Drive is a Cobalt Drive. Cobalt, Copper, Silver or Lead are good. (density > 8 g/cm3)

Drives of level four and above are expensive to operate and draw attention due to their rarity.

A level 4 Mass Thrust Drive is a Light Military Drive. Mercury or Light Radioactives are the preferred fuel. (density > 12 g/cm3)

A level 5 Mass Thrust Drive is a Advanced Military Drive. Gold, Plutonium or Uranium are used. (density > 16 g/cm3)

A level 6 Mass Thrust Drive is an Iridium Drive, used mostly on racing vessels. Iridium, Osmium and Platinum are used, usually as alloys mixed to the exact requirements of the finely tuned ejection system. (density > 21 g/cm3)

The MTD / Star Drive combination does not work well in interplanetary space (inside a solar system) so ships also require an interplanetary propulsion system – the Space Flight attribute. An advanced MTD will add its percentage speed bonus to both the Space Flight and Star Flight speed values.
