small update, been trying to figure out the look of the turrets and I think I still have some way to go to get them looking right.
http://p3d.in/SKoexarmament wise it is currently looking at
5x Anti-Capital beams - 1x upper head, 1x lower head 2x forward base of upper engine rise, 1x lower hull just aft of middle
5x Anti-Fighter beams - 2x upper head, 1x centreline upper main hull, 1x underside at the neck/hull join, 1 just below middle engines
2x2 blobs - dorsal and ventral multi-parts
4x Flak emplacements - sides of main body
4x VLS type missiles - lower neck
on the discussion about the underside, here are a few silhouette/semi silhouette shots to show the shape of the lower hull
while it is not as varied as the Hatty there is some curvature and variation there.
for the hanger, the entrance is not really changed but I have moved the hanger upwards and slightly back to reduce the severity of the curve, placing it pretty much centre mass of the main hull, still weighing up rescaling the hanger opening.
