What type of travel range will the Prowler be capable of?

The Prowler is a short-range craft, more akin to a landing craft than a long-range transport (in contemporary terms, think of a beach invasion). It's meant for assaults and boarding, not long-duration or long-distance patrol. Like many ships, it can be fitted with a jump drive and is capable of quantum travel, so it's got longer legs than a snub fighter or Argo of course, but you should think of the Prowler as a short-range ship, developed originally by the Tevarin to operate with military fleet support, as many small military ships are (like most fighters).
