Interesting. Surprising that the length is exactly 1000 meters, but okay. Radar, really? Should just have some superior cameras/sensor arrays that can create a holographic image from the light coming towards the vessel. Radar has to be sent from the vessel to the target, pings off that, and then has to travel all the way back to the vessel. Why wait twice as long for radar when you just have to carefully 'watch' the light of other vessels come towards the battleship? Secondary weapons? Use of missiles? What kind of weapon are the main turrets? Railgun, laser, massive missile launchers, or plasma? Defenses? Shielding? Armor (and thickness)? CIWS?
It also seems like the battleship has carrier capabilities. A major flaw, windows. An unnecessary structural weakness in space. Otherwise, a very streamlined/smooth looking battleship.
