Stuff like that
Some examples of 'mission-specific ships':
-Take this wonky T6, with my experimental scanner, and scan the unstable sun in that anarchic zone. Please don't damage the T6, it reminds me of my aunt.
-Return this Sidewinder to my feckless son and bring back my Eagle, which he's managed to crash. (And which he can't afford to repair, the reckless idiot. Don't buy him any drinks! He's annoyed enough of the local pirates as it is...)
-I need a driver for this T7 full of toxic waste. The contract's big, but you will have to smuggle it past security. Clearances got lost in the ether, you know how it is. Ship integrity is fine right now, absolutely fine. Bring it back when you're done though, I can get a lot for the parts.
-The Kinzo Crew are dominating the local extraction site. I need you to set up a blockade just for them. Disable four of their ships any way you can. This Clipper equipped with anti-FSD mines and guided missiles may help. Any spoils you accidentally find are of course yours to keep.
