For reference, the source material.

Of course, here the Harpoon canisters are staggered, so I guess I would leave them this way on the final drawing.

thanks for the help on the mooring gear.... and as said, the refs show them this way, so I'll keep the harpoons like this. and for the mast: could I keep it like this as well? I rather like it like this and the other CSGN concepts in the bucket all have black masts. if not, I will fix it, but if I can keep it and still be accurate...

As far as I can determine, every DLGN/CGN in US service had a gray-painted mast through its entire service life. The CSGN drawing should probably be revised in this regard.

sideview done, apart from the fixes timothyc might have done.... but I can't reach him ATM, so I thought to post this already. the top view is on my long term list, and I don't know if I will ever finish it entirely, it was mostly meant just to show the arrangement of the weapons, bridge and flight deck.

I have been discussing this design for a group build entry with some experts in ship design and here is a summary of what they feel is lacking along with a improved suggestion good luck
I feel the flight deck is too narrow for safe operations. I like the Kiev style thinking, but it's too crude, it needs to be refined. Wider, with some better styling. Maybe move the structure over the edge a bit and widen the flight deck with sponsons, like a carrier. Uglier, but maybe more practical would be the Moskva style with the large flight deck aft and all weapons fwd.

The mission is harder, Harriers and Cobras are for Marine support, but you have no accommodations, no way to offload marines and it would be too few aircraft to do much good for a single ship. 8" gun and missiles for land attack, but little anti sub weapons. If you go with the concept of large troop movers (LHD/LPA/LHD types etc) remove the offensive air component and make dozens of ships like these that bring in multiple 8"guns and Cruise missiles

being familiar with the helicopter/Harrier carrier built on a Spruance hull. The picture you included was the last excursion into the Strike Cruiser trying to make it a mega "I can do everything...even carry airplanes, too!" ship. As you can see from the differing pictures in the strike cruiser evolution the ship went from a surface combatant to a mini carrier with surface combatant qualities. I think the strike cruiser never came about, because there was such uncertainty in the basic design element that an "if you can't even figure out what the ship is going to do then get out of here," attitude developed amongst the procurement guys.
One thing we have noticed in the Ticos is that particular hull form is not very stable when there is a whole lot of weight built up on it. I am pretty sure an aircraft deck would do two undesirable things, both of which would keep the ship from performing air operations most of the time. First, a flight deck, even if low to the water, would possibly introduce a whole lot more weight to the hull and make roll a lot. Normally that's not a problem, but this leads into the next problem. If the ship pitches and rolls as much as a Tico does, the flight deck will probably touch if not dig into the water, and in other cases take water onto the flight deck, and you certainly would not be able to perform helo or Harrier operations.
If you wanted to do this concept I believe you would have to use the strike cruiser hull (which was similar to the Long Beach hull ) in order to get the flight deck up off the water, and like you pointed out would be more Kiev-ish. The Keiv ship was a novel idea, but it seems like the LHA with a tycho supporti it is indeed better off.
The mission for this kind of ship is really tricky, because it can obviously do a lot of things but none of them very well. When aircraft are operating the escorting Aegis ships have to very tightly regulate how they radiate with their SPY arrays, and if you're flying aircraft and helicopters right through your own the SPY beam paths, you'll have a whole lot of trouble with effective radar coverage...or cooking you pilots. I can't find a good starting point for missions, because it kind of does a little of everything (air defense, assault, surface combat, etc).
Concerning the Mk71 8", they tried 5" guns aboard the LHAs for shore bombardment, but they unfortunately removed the 5" guns, because naval doctrine moved to keeping all ships way off the coast in order to keep them safe from shore batteries. Because your ship might have to follow this same practice the value of the 8" gun may be limited to self-defense. In that case a bolt-on weapon system like Harpoons might be a better option rather than a giant gun system that has to be deeply integrated into the hull like the Mk71.
lastly for the air wing I would do 2-4 Harriers/F-35's and/or Cobras each, it could add up to a large air contingent with multiple hulls for redundnacy and flexibility, while increasing the troop carrying capability of the larger ships because they don't have to carry the attack birds.

I'd make it smaller, though, to keep costs down, cuz you'd want many hulls in the water.
Good luck...

I told Ace I'd help him out, so here are a few tweaks to his work:

While all that is true, it's not really relevant to this drawing.
Ace is rendering the CSGN mk 2, which is a fairly well defined design. Whether or not it would work isn't important.
What's important is that this is how the designers and engineers at the time thought it would look like, since that's what he's trying to capture.

I think you are missing the point about this ship.the role was strike cruiser, not LHD. this ship was an cruiser first, then an carrier..... and even as an carrier, it wasn't an 'real carrier', as it's role was not escort but strike.
for the anti- submarine capabilities: with a sonar, ASROC, torpedo tubes and possibly ASW helicopters, I think this ship will just be as good as an burke or maybe even spruance in this role.
the CSGN program was an huge program with different ships en designs. the way you say it 'the ship went from a surface combatant to a mini carrier with surface combatant qualities.'...... this was the second design in the series. I can understand why they haven't build it, you are right about quite a few of the design flaws.... but I don't see that 'csgn burke thingie' doing it any better. making in smaller also won't work, as you then can carry even fewer aircraft.

@ timothyc: thanks! I will finish the sideview tonight, do you need credit? and are there any points which still need changes? (I saw you already fixed the bilge keel, thanks ;) )

EDIT: finished it now :D

top view will come in an separate image in the future, when I have time to make the top views of the gun, mast, harpoons and rail launcher.

Two things:
There's no shading in the hull cut-outs and you've saved it as a jpeg.
