PLAN Naval Helicopter & ASW Capability II

Maybe I wasn't clear

I didnt mean all 30 are ASW

I meant LHD will carry ASW maybe 4-6 or 8 but certainly not 30

LHD would carry a assortment of SAR, Cargo, transport, attack and ASW

Mixing up for specific missions

Well its frequency's unknown but on another note after some digging, it turns out there is in fact a L-band radar suitable for an AEW helicopter; which is Ka-31's E-801M . Though its a planar array and not phased but if their difference isn't too big which I'm not sure, it's definitely a more appropriate example for a L-band radar that could explain 055's bars, than Su-35's antennas.
Su-35 and Su-57's radars are both L-band, the Ka-31's radar is L-band, this radar is probably L-band. All of them are bars. I would even venture to estimate that the large bars on top of the 055's bridge are larger than any of these radar systems and so would have at least somewhat better resolution.

E-801M's detection range is partly due to its size constraint but works on a platform looking over the horizon. But how about it was mounted a ship? Most authors describing 052D's yagi refer to the Soviet 'Knife Rest' as EW in context of its operational era in the 1950s, and known/estimate detection ranges of both don't surpass Type 346. On 052D and if on 055, are low frequency radars serving a different function, or is detecting LO targets justify them being called EW radars is my question.
The 052C/D's yagi antenna is considered to be an "early warning" radar, which is just another way of saying that a radar has crappy resolution but it's good enough to tell you something is roughly out in a certain direction. Likewise, if the 055's bars are L-band radars, they are good enough to tell you the general direction of an incoming threat (like an F-22 or F-35), which would allow you to use the S-band radar to narrow the search pattern to a specific region and devote more T/R modules to that area in order to pick up a stealth target that would otherwise get missed. At least that's how I think it works.

I still think official words/leaks are needed with Su-35s antennae but that's another story. With Ka-31, there's far better ground to the L-band search radar theory, and that they may not need to be super fancy like Smart-L. Electronic warfare is another one. Then there's the idea of separate high-peak powered illuminators like CEAMOUNT, which seems unlikely as HQ-9 homes in on interrupted CWI (similar to S-300FM/30N6E and Patriot/MPQ-53). Those seem to be the main 2 or 3 bar theories before any leaks.

That should be right with 052D. P-8 "Knife Rest" and 052C/D's yagi are 2D radars that can't provide altitude data, so they need to handover tracking to the S-band radar first before anything else. If 055's the same, then the main job of a low frequency radar, besides being a secondary/tertiary radar for back-up redundancy, is spotting LO targets even if their resolution/detection ranges are worse than that of Type 346A/B. They wouldn't need to be a VSR like Smart-L with many requirements ie. ballistic missile detection etc.

Same as British sting ray ?
Same size speed etc... about ASW helos are armed with only 324 mm a 533 mm do about 1.5 tons can't and a lot of ships have also 324 mm TL
Submarines always 533 or Russians also 650 US Seawolf 660 mm exist also 400 mm but very rare.
