For a quest I have to jump 27 LY. My current grav drive is only made for 25 LY and there is no system closer then the requested 27 LY.
All the ship technicians I asked can not offer a more powerful grav drive then the one I currently already have in my space ship.
What exactly do I need to get more powerful grav drive?
Is this only possible with a bigger ship from a higher class?
Or can I buy such a grav drive from some specific vendors on a specific planet or location only?
Or do I need a specific skill to buy such a grav drive?
Or do I get such a drive after solving a specific quest?
