Headcanon says, this is a Distant Sky Survey team. These guys are the third line of space exploration, dispatched wherever long-range scanners and robot probes discover something that needs human eyes on the scene.
The ship is unarmed, I think of those pokey bits in front as parts of the hyperdrive system. All the greebling is supposed to be sensors and, hopefully, enough stealth gear to keep the ship out of trouble.
There's an opening ramp, and the roof's designed to come off. Interior is a mess of equipment and stale coffee cups.
Behind the scanner operator's station, there's just enough cargo space for a little rack holding two carbines and a spare lifesupport pack, and a box for, apparently, the severed head of some alien.
I've been meaning to build these guys a proper ship for a while, and finally got around to it..thanks for looking!
