I'm curious. What, exactly, defines your maximum air draft? Have you considered it explicitly? To repeat myself somewhat, you have a very deep and heavy and gloriously stable hull. Hypothetically, what if you could raise the SPS-49 (and other stuff like that) six or ten feet? What effect might that have on your director layout?

I suspect, maybe without reason, that your arrangement is more governed by stack tolerances than actual topweight.
Thanks again erik. I had to look up air draft. The max should be about 175 feet. I didn't really think about this in a number situation sort of way. I was going by looks. Also I don't know what stack tolerances are. So, since I've no idea what you're talking about I will pose a couple of questions. Please excuse my ignorance. What would be the purpose of raising all radars another 10 feet, besides the obvious of gaining a few more miles of radar horizon? Secondly, it sounds like you would change the Director layout. What exactly would you do with them. Personally I really like them the way the are now. They have a "Long Beach" look to them, in layout anyway. They seem to have very good azimuth coverage in current layout also. I like it a lot, BUT I am willing to hear what you have to say on the subject. lastly, are there any calculations I can make to determine when something has got to top heavy?

I agree the Tico Harpoon location leaves something to be desired. I hadn't considered the impact of the split deckhouses on reactor refueling, but I was concerned that they might make operations in the north Atlantic difficult on crew that need to move between the deckhouses. Otherwise, your current location is probably the best options available.
Thank you for the comment ghost. I can tell you, from personal experience, that this split deckhouse setup would pose no problems with access between to two. The USS Virginia had this same setup, and if weather was sever you would just access them from under the main deck, inside the hull.


So this is my latest update. I'm really liking this and I hop I can soon call it done :) The biggest question I have right now is what do you think of the aft deckhouse having bulkheads all the way to the hull? I like the "eye-candy" of having it split BUT... is this better in the overall picture. in other words, is this better for the ship as a whole??

Now that looks one hell of a lot better than the original iteration!

Would it perhaps make more sense to transition to RHIBs on the later drawings btw?

You're going to need to access those SRBOC in service, carrying 50-odd-pound mortar rounds, and I wouldn't tempt the HERO gods putting them so close to SPG-62 in any case. Lower them to the main deckhouse aft. I'd think about relocating the forward pair to the aft location as well, abeam the after SPY-1 arrays; you have lots of open space and I don't think it matters greatly where the launchers are located axially on the ship.

I am persistently not super happy with the stack of four SPG-62 aft, and I feel like they could be tiered a little better for superior end-on illumination. Certainly directly abeam, illuminating on the horizon, you have exactly one dish that has a completely clear field of view.

You have a very large and weighty hull, and I suspect you could raise the mainmast (and the SPS-49) and solve this problem entirely. What's your maximum air draft right now? Are you close to any of the bridges under which you must transit?

In any case, it's looking very nice!

Thank you Trojan. I'm happy one like it, and looking back at this project it has gone through many changes. I want to start a new thread for a alternate history Frigate (from about the early 80's). Part of me dreads it because it takes SO LONG to come to a design I like. But at the same time I enjoy the journey :)

Thank you blackbuck. I agree completely. I look back at some of the older updates and I'm like...what was I thinking. its been fun though

Thank you again erik. I have moved the SRBOC launchers. I was thinking along those same lines but I changed it...its back to where you suggested. As far as directors, please don't forget that they (the aft set) are off-set from the center line, so in an end on situation there should be at least three directors with line of sight. I am going to raise the rear directors in each set though. I did an air-draft measurement in one of yesterdays update and cant remember the number...I think 170ft or so.

So here is CSGN-42 flight II. Hull Number's will start at 47

As you can see erik, the aft director in each set has been raised a bit. is this better or do we not them up even more?

Again, I'd like to thank you all for looking and commenting

As an after thought, I'd like to post the evolution of my Alternate History Project CG(X) 75. Would I do that on this thread for should I start a new thread? I'd like to show all my projects on one thread.

Wow. The 2000s version is even more epic! Nice job.

8" would be replaced with AGS lite

I am not sure if this would be all that important but I don't like that the RAM exhaust is likely going to fire directly into the intakes.

thank you guys. heuhen, this is a ship of the mid 90's. I don't think AGS was even delevoped then. I may go with AGS on the next flight, but I've not decided yet. I have to follow my alternative history and think about things such as, MK-71 has been deployed since 1975, and has probably undergone many upgrades. I would like some discussion on that thought if anybody is interested.

Shipright, I'm not sure if the RAM exhaust would have any negative affect on the turbines or not. They take in such a large amount of air that I'm not sure how they would be affected. I would love to hear other peoples thoughts on that issue also.
