Shocked. Guess I haven't checked it out yet...
Ecstatic. Get ready to get some new Subs!!!

@Starcloak: If you check out our ship collection, our workshops, or search for Ganymede, you'll find our Ganymede Class Utility Ship, it has nearly everything you asked for.

We are also currently working on a larger mining barge that has more industrial capabilities, including gas mining.

You can check our collection at Intrepid Raven Shipyards. The link is above the description.

Impressed. I really love this style of Ship Design, keep it up!!!
Curious. Are you planning on making a version with the capability of mining and collecting gases?
Additional. Another cool set of features would be Solar Panels that extend out like the one on the Hermes from the (Movie) The Martian, except maybe double-sided and extending from the top and bottom as well as the sides, along with maybe a small Data Core dedicated to the Data Cores, Expansion Bays, 3D-Printers and/or Cyber Warfare Terminals.
Disclaimer. All these ideas are to be credited to you in the case that you actually use them, just giving you some ideas with which to expand on.
