After finding only fighters that have astromechs that are jump-capable in the books I have, I'm wondering: Are there any fighters in expansions or supplements that are jump capable and don't have an astromech?
(I'm talking here about an innate jump capability, not one with acceleration rings).
Or is it that, for fighter-sized ships, an astromech is a must-have if they are to be jump capable in the game setting?
