The Imperial-1 Star Destroyer is armed with 60 heavy turbolaser cannons,60 ion cannons,6 dual heavy turbolaser turrets,2 dual heavy ion cannon turrets,2 quad heavy turbolasers,3 triple medium turbolasers,2 medium turbolasers,10 tracter beam projecters,and probably more. I would put the quantum torpedo launcher's range around a million kilometers. The maximum range of the ship's phasers are around 300,000 kilometers,and the photon torpedo launchers have a range of 750,000 kilometers. Quantums torpedos have the explosion yield of around 100 megatons,and the photon torpedo launchers have a yield of 65 megatons. The Enterprise has 16 phaser arrays,1 quantum torpedo launcher,and 9 photon torpedo launchers. The Enterprise has as much as the Star Destroyer's Starfighters,while the Star Destroyer is slow at maneuvering as see in a New Hope,Rogue One,and Return of the Jedi. Winner:Enterprise(sublight speeds),Star Destroyer(faster-than-light speeds) The Star Destroyer isn't as fast as the Millennium Falcon,but it's close. The Millennium Falcon in Star Wars went half way across the galaxy in a few hours(or days),while it would take decades for the Enterprise to get half way galaxy at maximum Warp. With the highest speeds,the Star Destroyer wins. The Star Destroyer is stated to go up to 975KPH at sublight speeds,while the Enterprise can push up to ¼ the speed of light(268,760,448KPH),meaning the Enterprise is way faster at sublight speeds.
