055 DDG Large Destroyer Thread

[Richard Santos]

The most obvious answer would be not enough room. Even the smaller bar which is probably the IFF is only integrated into the mast in the rear quadrant, with the other three being placed on top of the bridge.

The alleged antennas do not seem to take up much room. It seems improbable that the design for so large a ship could be so tight that room could not be made for them in the original superstructure/mast design if they had been part of the ship's core equipment from early stage of the design.

I think the way they are mounted suggests:

1. They were a late stage addition to the ship's design, added after the superstructure and mast designs were already completed, possibly after fabrication of these parts had already begun.

2. They are not considered truly vital to the ship's most important mission, otherwise the ship would be delayed to allow design revisions required to properly integrate them.

yes, and those boxes on top the bridge are very big. They are the same length as the width of the X-band array panels.

I think you mistaken the X-band panel width with X-band antenna size determined by wavelength of X-band. The X-band array (under the panel) has many TR modules in a row. The size of each module is determined by the wavelength, not the whole array.

I didn't take into account of the X-band antenna size, but was confused why each box is smaller than Smart-L presumably with more elements. Is it because it shares the volume search task with the Type 346B, more focused on detecting LO targets, the fact they're fixed not rotating, or something else? My take is that a fighter's L-band antennae's size or somewhat larger, doesn't seem to satisfy a VSR needed on a ship.

L band is 1 to 2 Ghz corresponding wavelength 30 to 15 cm. That means each L band TR module is no larger than 30 cm. The boxes are around 3 meters or longer, large enough.

X-band is 8 to 12 Ghz, wavelength 3.75 to 2.5 cm (1/10 of L band). That is around the size of a TR module which is essentially a power IC chip.

Thanks I knew arrays consisted of TR modules but not that their size were based on the wavelength. So is a TR module on a X band array is 3.75x3.75 cm max, and a L-band array's TR module is 30cmx30cm max, correct to say?

Also why does every ship based array, have each face in rows of TR modules look boxy-circular, and not covering the entire space? I know squat about how shipborne arrays are designed.

This is how it should look if the resolution and angle were better:
View attachment 41114

Yes it is how it should look...and no matter how I zoom in, and use some of the special graphic enhancement programs I have, I cannot get the double doors to resolve.

That angle and the lighting and the distance are not so far off that we would not be able to see them.

...my radar antennaes and conspiracy mind, coupled with the tools I have that should resolve this are just kicking in...that's all.

2. They are not considered truly vital to the ship's most important mission, otherwise the ship would be delayed to allow design revisions required to properly integrate them.

Just because they are not integrated into the main mast doesn't mean they are not important to the ship's mission. I think you are overanalyzing this somewhat. Perhaps the increased topside weight of a larger mast was not worth it enough for the designers to create a large enough mast to integrate both sets of sensors, whatever they may be. Perhaps there are interference issues. Perhaps integration of these two sets would only minimally decrease the ship's RCS compared to their current arrangement. There are many possible reasons they did not integrate them, which don't have anything to do with these sensors being less important or coming late in the design of the ship. We know at least one of these two bar-like sensor sets must be the IFF arrays, which means there is no way that sensor set is an afterthought or came late in the design.

Another obvious answer would be EMC.

I mentioned that as well.

Reading the news, US plans to counter China major surface combatant warships build up such as 052D, 055 with more SSN, such as Virginia subs. They figure subs pose more danger to those surface combatant warships. China really need to have its 095 to show up as more and more Virginia subs being built. Need to strike a balance.

Agree, starting from 095, I believe China will mass produce those SSN, perhaps up to 12 units until moved to 097 in 2020-2022. I believe mass producing 095 is already happening

I have not seen any evidences of 095 though.
Had this strategic weapon already built or just started, they would already leak some photos on purpose , trying to impress like they had done recently with other systems.

The 095 is still a no show and you feel the "097" will start production in 5 to 7 years? If the 097 arrives before 2030 that will already be fairly ambitious IMO.
