WOW! What ship is this and what missile did it get hit by?

For some reason the video edited two separate ships getting hit together.

How many brigades of YJ-12B deployed and how many missiles ?

Who would dare (and with right mind) to come to China' shore within 1,000 or 1,500kms now?

TLDR, the estimate is 104 total launchers between the YJ-12 and YJ-62, but it's hard to tell apart which regiments operate what, and some probably run both among different battalions. Also, the YJ-12 absolutely cannot reach out to 1500km. It probably does around 500km when air-launched, somewhat less when ground launched like this.

on PLAN coastal defences a few months back. At least five confirmed regiments with a mix of YJ-62s and YJ-12Bs. Each regiment nominally has at least four battalions, which each have four TELs. But there's a lot of uncertainty between the types and organization.

I wasn't suggesting YJ-12 has 1,500kms range ... but with many missiles and anti ship BM and air launched, very much China's shore is safe at least 1,500kms out

I doubt it is just 500 km air launched.

Posted this on the Chinese Hypersonic Developments (HGVs/HCMs) thread, but I think my post is more relevant here.
I did warhead vs range estimate of the YJ-21.

Thoughts on the range and payload of YJ-21. One thing that always intrigued me is how the YJ-21 with a dimension similar to DF-15 can achieve a much greater range despite being a slightly smaller rocket.. Let's compare:

YJ-21DF-15A
Range: 1500 km
Dim: 8.7m x 0.83m
Payload:?		Range: 900km
Dim: 9.1m x 1m
Payload: 600kg

One way to get a greater range is to use a Sanger ballistics (You also lose energy by doing that), but I wonder if the same can be achieved by having a smaller payload. As the YJ-21 doesn't need a 600 warhead to inflict a mission kill on a carrier.

After some googling I found this graph: Link:

Assuming this the info in this graph is scalable for our range.
I'm also using Region A as I don't fully understand what each region represent, people better at rocket may want to correct me.
1500km/900km = 1.67
So I geed to figure out how much the 600kg warhead need to reduced to achieve a 1.67x increase in range.
In graph: 600kg, 250km ish range.
So we need the warhead mass for 250x1.67= 417 km range.
View attachment 135841

So got a warhead mass of 200kg, which is a warhead mass slightly smaller than the Harpoon (221km).

However, I think with a terminal speed of Mach10, 200kg is enough to achieve a mission kill on a Carrier, but def not sink it.

What do you guys think? Feel free to improve upon my finding.

So it looks like the AShBM which we have been referring to as the "YJ-21" actually has the official designation of "YJ-20"?

Apparently someone went to visit the #165 052DG Zhanjiang during the PLAN's National Day exhibition event and saw one of the exhibition boards onboard the DDG with the missile designation "YJ-20":

From two years ago, when @洋务先驱张之洞 on Weibo hinted about the supposed correct name for said AShBM:

1000142145.jpg

And according to @洋务先驱张之洞, he first came to know about the YJ-20 AShBM all the way back to 10 years ago (which isn't exactly surprising, given that the YJ-20's model has appeared in academic papers from as early as 5 or more years ago, including that multipack VLS tubes for next-gen SSNs).

@BoraTas you're right. Though there's still a big question mark on what the YJ-15 actually is for the time being (rumored to be a supersonic AShM that fits inside the UVLS).

So this thing is the YJ-21:

And this thing is the YJ-20, not YJ-21:

In the meantime - YJ-20 isn't the latest AShM in the PLAN arsenal.

Tbh I have some doubt if that "YJ-21E" is even necessarily related to any actual PLA in service "YJ-21" that may or may not exist.

The "YJ-21E" when it emerged back then felt like it was deliberately choosing a name that was rumoured as associated with that UVLS launched AShBM/HGV and then putting a "E" on the end of the name to make it seem like that specific product had more significance than it actually did. (Considering it's shown with the TL family of weapons from ALIT, I suspect if they're just pulling a marketing gimmick)

That is to say, it is possible that "YJ-21E" (the specific export product shown there) is completely unrelated to whatever actual "YJ-21" that may or may not exist for PLA use.

As for the actual UVLS launched AShBM/HGV in question, it would not be unreasonable for its name to be YJ-20.

It is also possible that YJ-21/YJ-21E is the single stage missile and YJ-20 is the YJ-21 with booster stage.

Is this a tacit admission that the Type 052D can be armed with the YJ-20/21? It wouldn't be surprising if so, given that the 052D and 055 share the same UVLS.

When we learned YJ-20/21 was launched from the 9m UVLS a few years ago, I thought it was already considered a generally accepted consensus that 052D would also be able to be equipped with it, given it also has some 9m UVLS.
