From publisher blurb:
The Independence-class is a 500 ton armed freighter designed by Liberty Ships of Franklin (Franklin 0506) for Diamond Enterprises in 2330. The design team, led by famed vehicle designer Adriana Gonzales, met with Diamond Enterprises CEO Maxwell Chandra at his home on Bastiat (Franklin 0807) on five occasions to make sure that the design was exactly what Chandra wanted. Chandra was looking for something to replace his company’s aging Rucker-class ships but didn’t want a ship as large (and as expensive) as his fleet of Atlas-class ships. Chandra specified that the ship must be able to enter the atmosphere of worlds with only a downport, that it must be armed in order to resist pirates and other corporations, and that it be stylish. Chandra’s other specification was that it not have the same general appearance of other ships designed by James Lancaster (such as the Atlas) as Chandra wanted to separate himself with what had come before.
Whilst the Independence is specifically designed for the Earth Sector or Clement Sector setting, each of the ships could easily be used in other Cepheus or 2d6 SF RPG settings if needed. (The Zimm drive is very much like a J2 drive)
