I believe they are uhf radar antennas
As I said before, there is certainly no doubt that China has gained a tremendous amount of proficiency in software development and integration. But there is no way for us to know how far they have come. I am totally open to the idea that they have surpassed the US in some areas. BUT as far as AESA vs PESA and the attached combat data systems go, this small blurb from Henri K doesn't do anything to change the assessment that we still don't know how each system compares to each other.
The cost of ~1 billion pounds for the Daring includes R&D costs. At then currency exchange rates, that's about $1.6 billion. I have not located unit costs for this ship. Given that it's a 6-unit build, the R&D costs will certainly occupy a large percentage of this figure. The costs given for the KDX-3 are unit costs, not project costs (project cost being unit cost + R&D per capita). Also, it is very important to note that the KDX-3 literally uses no new technology, and this is a frequently given reason as to why it's cheaper compared to other ships. All systems were bought from other countries or were already present on the KDX-2 class. Similarly for the Kongo; I think the only new system for the Kongo was the ECM. I certainly don't deny that there is a country of origin discount, and as large shipbuilders Korea and China would accrue savings from both efficiency and scale, and in the case of China, labor as well. But we should definitely not forget that besides the weapons systems, almost all (if not ALL) of the electronics on the 055 are literally brand new. If as I suspect the AESA on the 055 has separated the volume search and fire control functions, it definitely is a new variant of 346 or even new radar altogether. On top of that is the integration of sensors into the hull and mast, which as I mentioned has quadrupled the costs for several of the sensors/emitters. The electronics make up the lion's share of a warship's cost, which is why $923 million for a 055 seems low to me. If this number is the unit cost not including R&D costs, it would be somewhat more within the realm of possibility IMO.
Well if pop3 said it, it certainly has much greater weight. OTOH it doesn't mean his involvement meant that he had access to the actual overall costs of the program. The other thing is we don't know the standards that each navy has wrt various things like armoring, damage control, redundancy, mil standards, and various other little details that could jack up the unit costs of a ship.
But how do you know outside USN the 055 is a destroyer and not a cruiser (I mean besides China)? I'm pretty sure that outside JMSDF circles the Hyuga/Izumo class "helicopter-carrying destroyer" is a helicopter carrier, because that's what it is regardless of what Japan calls it. Actually I think inside JMSDF circles it's also a helicopter carrier because I'm confident there are realists in that organization. In any case, I don't give any credence to any alleged "fleet command" capabilities of ships like the 051 or 052. We are probably talking about a room with a table and some extra phones vs a CIC with dedicated C&C and communications consoles. The 055 represents a fleet command capability unmatched by and uncomparable to any previous ship classes on both quantitative and qualitative levels.
This doesn't make sense because 12k is widely believed to be the full displacement of the 055, not the "normal" displacement. And 4k is widely believed to be the full displacement of the 054A, not the "normal" displacement. So in order for his scheme to be accurate you have to believe that he quoted standard/full/standard/full displacement figures for the 056/054A/052D/055.
This CGI is one of the few (if not the only) CGIs that got the placement of the RHIB garage correct. It was also the first one I saw that predicted an enclosed foredeck design. The Z-8/18 is a bit optimistic, though.
I think the 055 does have an intake/exhaust/exhaust/intake arrangement for its GTs, though it looks like the forward intake may actually be that giant gaping rectangular hole going straight down into the bowels of the ship.
You should look at the description of the FCS-3. If the Akizuki actually uses a C/X-band pairing, the C-band will definitely be in the lower frequency portion of the band where it and S-band are at nearly the same frequency. Since the C-band portion of FCS-3 is used for "surveillance", this is almost certainly the case, which makes the C-band radar essentially a slightly higher frequency S-band radar. The lower the frequency the longer the range and the less accurate the track, all other things being equal, which makes lower frequencies more suitable for surveillance and higher frequencies more suitable for fire control. Your example of X/C/S would still not be tenable because the C-band radar in that combo has no real role that isn't already occupied by the X- and S-band radars.
Yes...it is Japan's home grown AEGIS-like Battle management system...and it my understanding that it is completley cooperative with it.
I imagine that this Chinese type 055 has something very similar developed in China.

WOW! Beautiful shot. One of the best so far!
Red is IFF. Yellow is ESM. Blue is ECM.The arrays on top of each Type 346 panel are positioned the same way as those on 052D. Do they serve the same function? Also what are the other sensors marked?
I should've paid attention when 052Ds first came out...

Some quick observations and questions...
It appears the muzzle brake on the main gun is different or hasn't been installed (?)
What are the panels circled in red? Could 'A' be a L-band AESA panel, however unlikely that is? What about 'B'?
Here's another view of the aforementioned 'B' panels:
I believe B is EW antena, similar with US SEWIP
