Thet's not what I meant by the use of the Y-Wing Longprobe. Suppose a group of pirates attacked you. If you were flying alone in a Longprobe, wouldn't you be defenseless as to shoot back? (assume that they had an interdiction field to stop you from going to hyperspace).
Longprobe is a cheap, fairly fast expendable probing ship. Maybe the name hints at the fact that it has much better sensors than most fighters and better than some freighters and even equals most low level caps so what it can't see first it can ususally outrun. I mean if you can see somthing from 8 squares away then you won't be in the grav well of said interdictor anyway or if you are then you can surely outrun it. I'd take the sensors over guns if i was a lone pilot.
