I'm perplexed... What good would a Gladiator be if it doesn't have jump capability? There are no carriers for sale, right?
As far as I understand it every system has jump points which normally require some kind of jump ability to go through. However, in the more built up areas of the galaxy there are jump gates constructed and any ship should be able to go through those. You should still be able to cruise the galaxy in a gladiator, just can't go visit the fringes without hitching a ride.
