I'd like to make a support NPC for my acolytes. I plan to have their inquisitor provide them with a small space ship and a landing shuttle of some kind that will probably be part gun cutter/ part crew transport. For this I'd like to make an NPC that can pilot the shuttle and their ship both if needed. I imagine the larger ship as either A) Being some sort of Xenos tech capable of warp on its own or B) basically docking with other warp capable craft and hitching a ride. (sort of like how space travel works in Dune)
I figure this NPC works best as an ex-guardsman, former fighter pilot. I was looking at Guard advances and you can eventually get Pilot (Military) and Navigation(surface) but never Pilot (Space) and Navigation(Space). So, what is the best/easiest way to make this work "legally"? IE, I want the NPC to be built with the same rules as the PCs and not just made up whole cloth. I figure by the time the Inquisitor gives the PCs this ship it will be their 4th career rank or so.
I am thinking Elite Advances are probably the way to go but I wonder if there is something in one of the many add-on books I've missed.
