There's the STAR Initiative, and I don't think that they have a website, but you can find them in the Fleet Carrier Owners Club Discord server. EDAstro's interactive galaxy map does track and display the network's carriers, like it does the DSSA's; you can view that here.Wow, that's excellent, I didn't know there were carriers with Tritium for sale far out in the galaxy. Is there a list of which ones do? I guess they would show on Inara but that may not be the easiest way to plan a voyage.
