He had a select group of interceptors equipped with sheild generators since they were to valuable to lose. That info is from a thrawn trilogy guide.
Wouldn't be to much fun as a game to die when you get shot once, and in those games you need to be able to take alot of damage since your sheilds don't recharge unless you change your power settings.
One of the things about Rogue Squadron, they don't bat an eye unless they are fighting more than 2 star destroyers and all thier fighters (72 a piece) then they say they can hold them off till they have to back off. I think that happened in Shadows of the Empire.
I liked the X-wing novels I read, which was like 7 of them, those some of the prequel books and the some of the young jedi knights are the only novels I haven't read, but I have all the material.
The assualt gunboat only shows up in those games I think, I have never seen it in any of the books. Star Destroyers are cake in those games too.
The same can be said for Wing Commander shields, laser cannons in Star Wars aren't typical lasers. Star Wars ships do have particle shields, they work alot like navigational deflecters from star trek.
In the movies not to many fighters survived unless they were flown by a main character. Luke and Wedge, everybody else got wasted, it can't be all that durable since it is about the same length and size of an Epee.
The Y-wing is actually more durable than the X-wing, it is merely old, I am wouldn't be surprised if it makes an appearance in Ep III, I heard that the Z-95 head hunter might.
I can concede that more than likely, probably certainly, that WC fighters are better suited for combat than SW. Speed...that is a difficult thing to place, in regular space I might be inclined to saw WC might be ahead, though a SW ship will always beat a WC fighter in a race over distance.
WC has the advantage in carriers, while SW has the advantage in in capital ships. The Confederation couldn't beat the Empire, hell Confed, the Kilrathi Empire, and the Border Worlds couldn't beat the Empire. Considering the largest ship is the Hvar'kan at 22km, the empire has "alot" of command ships and they are over 16km long and armed a hell of a lot better.
But as I said before, this is all conjectural and doesn't really mean everything.
