I thought all SY were orbital anyway. If you want the pop mod you need to be on a high pop planet.

If you look at the Grayson Space Navy as an example. They have few SY (Blackbird being the largest) yet they produce lots of SD's and the like. Remenber that the GSN had more SD(p)'s than the RMN and all of those were produced in just a few years.
