SS Conquest

The SS Conquest was a Terran DY-500 class transport in service to Earth's Merchant Marines in the 22nd century. 

In 2149, the Conquest participated in the colonization of Seclix Prime. .

Background
In the role-playing supplement, they list the Conquest with a registry of DY-257. Any ship with a registry higher than 200 is a DY-500 class transport. However, this information contradicts the canon information seen in "Up the Long Ladder" which lists DY-xxx as a class and not as a registry. Therefore, for this article, I have kept that the Conquest is a DY-500 transport and dismissed the rest.
