The armament starts to appear.
Using a naive, proportional scale up, this ship is ~20x the volume of an Imperator. ~7km long. The comparison places the ISD to starboard and back of this ship, so makes it look a bit larger than it is. I'm VERY loosely basing it off this silhouette: http://www.theforce.net/swtc/dagger.html#cruiser5
, just bigger.
Definitely heavy star cruiser class if Executor and Imperator bookend the range at star dreadnought and flotilla destroyer. Probably would qualify as a battlecruiser or battleship on the Old Republic scale. Not sure if I want to call this Praetor/Procurator or give it a new class name, which would probably be HIMS Warrior or Thunderer if I did.
As for power generation, I'm thinking 30x ISD equivalents, based on 20x ISD volume and greater emphasis on fleet/ship-to-ship engagement. There will be relatively little in the way of hangars or intervention troops. Maybe 24 squadrons worth with a 3 legion formation of stormtroopers, more infantry than heavy vehicles. All of which leaves greater proportional space for power generation, and structural stiffening for a large gun battery and high-powered engines. Plus, stylistically, there will definitely be a very large reactor bulb, and probably a secondary bulb.
I've put some thought into the armament, which starts to appear in these updates. I am using Remnant's 'calibres' of 32 teratons/heavy shot for the heavies on an ISDII, getting ~170 teratons for an ISDI from the heavy guns. I'm calling superheavies in the 200+ teraton range. Based on that, I'm currently plotting out a fit of the following for this ship:
22 400 teraton superheavies in (11 twin mounts)
192 ISDI-class 170 teraton heavies (48 quad mounts) - you can see the first of these turrets in this update
384 40-teraton heavies in octuples (x48) - again, I've put down the first battery of 32.
72% dorsal mounted, 28% ventral by throw weight. Total throw weight of heavies, 56.8 petatons. Optimum forward dorsal arc: 38.1 petatons. 64x32 teraton heavies for an ISDII puts out 2.05 petatons, so ~28x the firepower of an ISD's turbolasers.
I'm not counting mediums guns, since they are at a detail resolution where you can't see the gun barrels on the model, but if you count the greeble that I'm using to represent them, there are currently 23 mounts, which I'm going to say are twins of Acclamator-scale 200 gigaton mediums or twin medium ion cannon. At this density, I'm going to project around 400 medium barrels of both types, but I'm not going to count them all on the model. Add another ~80 teratons to the final armament figure.
There will likely be a missile battery and heavy ion cannon of the ISDI type, but those numbers I haven't sketched out yet. Probably looking at ~24-32 heavy ions in quad ball-socket mounts in the trench notches, and some in twin ISDI-style turrets scattered about the hull. That should round out to 30x firepower output of an ISD, same feed to the guns.
The superheavies I'm spreading along mostly axial positions for the best arc. With most of the 170s in batteries similar to an ISD's flank turret lines, but staggered for a better arcs. I'd have considered a "lighter" uniform caliber, but there's actually a limit on the surface area available for turrets on this thing, without making it too fanwank looking. I reckon the quad 170s can be exchanged for twin 400s in roughly the same turret.
Red for superheavy twins, yellow/green for quad ISDI guns, blue for 4xoctuple 32s like an ISDII.
Again this is based on a conservative, straight-up scaling from an ISD power number by volume. Those numbers could still change.
Whew long post. Looking at the bow structure later. Right now building a repertoire of details that I can use to assemble the rest of the ship.
