I too, commend your research, however there are two flaws with your comment about out manoeuvrability. First, Most Imperial Vessels (I mean all the vessels developed past 12 BBY ) are equipped with Tractor Beams. This would effectively keep the Prometheus in one place and let the Star Destroyer blast it with Concussion missiles.
Second, The Star Destroyer is slow, but it also has 4 squadrons of TIE Fighters (12 per Squadron), and 1 Squadron of TIE Bombers. And about your comment regarding Hyperspace, when you fly in hyperspace, you aren't flying "blindly," you are flying a very specific path that you designated through coordinates. Your craft is also not piloted by Humans at this point, as flying in hyperspace is done by highly advanced flight computers. Also Hyperspace is MUCH faster than Warp Speed.
About the Prometheus fireing out of the Star Destroyers Range, The combat range of the Prometheus is about 20 km if I remember correcly, however the combat range of a Star Destroyer is about 3,400 km in comparison. Another asset that the Star Destroyer has is Ion Cannons, who's main purpose is disabling shields and shutting down electronics. Think of it as an EMP blast. Anyway, I'm tired and need to go to retire to my quarters for rest. I'll continue this later.
For starters, Their not SWORDS (you should have said VibroBlade, then We could talk) Their called Lightsabers. Also, blasters and guns are tow different thins, but there are "Guns" In Star-Wars, however their called slug-slingers. Also, If you don't consider Star-Wars a Sci-Fi, but rather, a space drama, then what does that make Star-Trek? A space Sitcom? Also, shots fired by slug-slingers (which have much higher muzzle velocity than our real world counterparts) have been blocked by force users. We have Jar-Jar binks, yes, but you guys got Tribbles to deal with, so yeah.
