After stumbling upon this debate I felt I had to offer my own humble opinions. Scanning through the various messages I’ve seen good points made and interesting questions raised on both sides of the issue, but here are the basic facts that I think tip the scales hughly in favor of the Star Destroyer…
For the sake of this discussion, let’s assume a standard Imperial Star Detroyer and not the larger monsters Vader was fond of. I think the standard version is enough…
Can the SD’s turbolasers effect the Enterprise? It was mentioned that turbolasers might not even effect the Enterprise’s shields, based on a comment in a Trek episode in which they scoffed at ‘lasers’ being used against the Enterprise. Well ‘turbolasers’ aren’t ‘lasers’. Lasers are basically just amplified light, they impart no kinetic energy. They just cut through their target. Star Wars era turbolasers have a kinetic effect (the bolts ‘explode’ upon impact). So based on that alone I think it’s safe to say that turbolasers would definitely be effective.
Size matters: The ISD is 1600 meters long, is equipped with 60 turbolasers, 60 ion cannons, 72 tie fighters and a crew of approx. 37,000 (not counting droids). The Enterprise D is 641 meters long, has two photon torpedo launchers, one phaser array ring (unknown how many phaser shots can be fired at once, but episodes have shown it firing at least 5-6 at a time…figure at least 12 just to be fair), and a crew of a little over 1,000. Both ships have shields (i.e. electronic defenses), but the ISD also has heavy plate armor. Everything else aside the ISD can soak up a lot more damage just due to its size. Also, the Enterprise has ONE weapons officer firing ship’s weapons. And even if he can fire all weapons at once that’s one spread of torpedoes and about a dozen phaser blasts. The ISD uses a gunner for each weapon, giving it 120 shots at one time, not counting the tie fighters. And of course the Enterprise would be swarmed by tie fighters, both standard and bombers styles.
Can Star Trek transporters go through Star Wars shields? We have no way to know for sure, but if Star Wars shields are effective against weapons it stands to reason that they would effect transporters as well. Why does this matter though? People have mentioned that all the Enterprise would have to do is transport a bomb to the ISD. Moot point, the Federation doesn’t fight that way. When did you ever see the Enterprise “bomb” an enemy ship? They had plenty of opportunity to do so, but they’re too honorable to do that. But assuming that they get desperate enough to do so the ISD’s shields would most likely stop their transporters. If not, the ISD could soak up a lot of damage that way while it’s weapons and tie fighters were ripping the Enterprise apart. The only other reason to use the transporter would be to board the ISD, but the Enterprise doesn’t carry marines, and even if they used their entire crew they would be out-numbering 37 to 1, against Storm Troopers in body armor and heavy blast weapons.
Due to sheer scale of size and number of weapons the ISD would definitely be the victor. The Enterprise could escape if it wanted. While hyper-drive is faster than warp it has to be plotted in advance and it’s basically a straight-line mode of movement. Warp is ‘steerable’, so the Enterprise could duck out and escape but it couldn’t hold it’s own against an ISD in a one-on-one slug feast.
Now, if you really want to consider a fair fight…how about an Imperial Star Destroyer vs. the Battlestar Galactica?
