Anyway, in my Minecraft comic strip, I could (key word being "could") use it as a BI-72 Panther freighter vessel, a standard-issue Endian supply ship, with 3 crew members and comfortably holds 12 soldiers and 4 long tons (a long ton is 2,240 lbs) of supplies.
Looks like a ship in the "Space transport" size class, going by the Star Wars d20. Along the lines of the Serenity, or a YT-1300 freighter (i.e. Millennium Falcon) - or, if in an official military, an escort/frigate/gunboat class. Somewhere between a fighter and a capital ship.
And, continuing my speculation... Since it has wings, it looks like it's intended to be atmospherically capable (which supports the small-cargo freighter idea). Heavily armed (either the area's lousy with pirates, or the cargo's not strictly legal). Interesting how much one can (try to) deduce from a well done picture.
