1) The bulb shape is actually substantially different from SQS-53, it's just roughly the same size.

2) No, unfortunately. It's barely even possible to work in the two 4' dishes.

3) You are correct about the MX-10MS (sorry, not -10S) high on the mast. There are three greenhouses on the superstructure, one underneath the pilothouse (notable in the structural cartoon) and one on each beam below the 7' SATCOM dome (these are ugly and I have reverted to flush-mounted windows). Behind these, there is a MX-10MS surmounting the DIRCM laser turret. Each of these is rather small (on the order of 1').

Thanks for the reply!

I thought you were ready to replace the two original dishes and the 50mm with a single 7' dish?
If you clear all that off of your bridge, there is largely enough place for a 7' array (based on the one over the hangar), and at least one 50mm to boot.
Here are a few iterations:
1) Asymmetrical layout based on my original assumption of adding a sponson to support the 50mm
2) Turns out there is enough space in such a layout to remove the sponson altogether and site the 50mm closer to the mast
3) The new dish eats away at the firing arc of the 50mm, so if you can afford sponsons, you can compensate by adding a second 50mm, and fall back on an aesthetically pleasing symmetrical layout.

Am I missing something that might make this impossible?

I suppose not. It's a question of to what extent one values a wide field of fire from the 50mm mount, and how much freedom of movement you want to give crew who are going to have to be servicing these units. I very carefully located things initially for such access, not necessarily to every side of every system but at least so that people could reach them.

Given that the aft 7' installation already enjoys an extremely wide field of view, my initial inclination is to keep 2x4', but I'll have to ponder further.

Erik, pair up a few of these as escorts to your objective global warship and you have everything you need to take over the sealanes.

Ugh. I wish I'd never drawn that thrice-damned stupid thing.

Regarding satcom setup, I performed a conservative calculation of the blockage presented by the forward superstructure to the 7' dish, to 10deg below the horizon (to account for pitch and roll), and it is on the order of 5% for the destroyer and 4% for the cruiser. I am perfectly willing to have the remaining 5% of the sky covered by 4ft dishes, which present at least the same data throughput as what Burke has aboard.

Just a stupid one.... just because I can!

how often is the crew supposed to service these units. When can a simple lightweight scaffolding be used, a scaffolding that can be stored in the structure, and just pop up, when needed.

The scaffolding could be more like an hatch that is build into the structure... and just come up when needed. thus you can have an type of scaffolding that have some-what reduced RCS, compared to anything else.



I work in the industry on big CNC machines, and I know how irritating it is, when you try to do maintenance on the equipment.... but you can't get to it...

Heuhen, I don't really understand your question. What units, what scaffolding would be required, what structure?

Anyway, more minor artistic revisions. A change in door type (now sectional horizontal sliding everywhere) allows for a return of the separated UNREP station (near the 3/4 position, nice!) and allows for further separation of liferafts. I wasn't super thrilled having fully half of the units on the ship right next to the torpedos. The loading crane/11m deployment boom is also improved, although I won't get into the nitty gritty unless somebody is picky.

Oh, and deleted the high-up MX-10MS, because... what the hell was I thinking? I have a giant optical train up there already! You would logically interface the laser turret mirror chain with some sensors, as apparently the unit on Ponce does already. It is highly valued in this role, IIRC. I think I just added that unit in the first place because it felt like I had an open space that I should do something with, and that is a bad instinct. Role governs function governs form.

Also I put little dudes on the emergency conn, so that's sorta fun.

It's a small thing but I wonder if the helicopter control officer has a good enough field of view of the helicopter deck.
And with two landing spots and however many helicopters and drones you'll be operating you may need a dedicated flight control center rather than one guy in the CIC pulling double duty.
Oh and all the windows seem to have turned slightly purple

Fair question, I have no idea. You can see in the cartoon up at the top of the page that I've got something like a 8-10 foot wide space for helo control, and I think the windows provided ought to give a sufficient view to see the entire deck, but I have zero clue what operations are like in practice. UAVs are certainly an interesting open question but I can't imagine why you'd ever need more than one control person per manned helo...?

I have changed my window color partially to reflect that these are likely metallic glazed for signature suppression and partially because I have no intention of ever having a personal design be uploaded.

Changes, changes...
  • SPS-73 is replaced with Scout
  • We're down to two MX-10MS, but still with 360deg coverage, now much higher up and less subject to haze and spray
  • DIRCM is revised again, now with four units that should offer at least two jams on any bearing
  • Laser turret now has 100% hemispherical coverage
  • VHF/UHF beyond ICAS is now the usual pair of OE-538, but with a pair of VMB-11512 for 1) maximum LOS (atop the laser turret) and 2) at the helo control station
  • There's now a collapsable HF whip aft on the port side, for better comms in this band
  • The drawing now features a REFLECTOBELT, which should probably be mandatory for modern drawings
  • Vigile lives on at the masthead for horizon radar-band ESM, below Scout, but two AZE are introduced (inverted, which seems like it should be okay) for comms-band ESM. These are backed up by 20' interferometric arrays above the pilothouse and below the 7' satcom dish for precision DF. Goodbye and RIP, cruciform setup
