YJ-18 needs the 9m length because it is hot launched with a booster which in turn needs the concentric canister launch exhaust as well which adds additional length.

On the 052D, the two rear 8 cell modules in the bow 32 cell VLS section is thought to be 9m long alone. On 052D we've only seen YJ-18 launched from those 16 VLS cells.



Regardless, you haven't provided any evidence to suggest that the UVLS is limited to supporting payloads of 1.5 tons, so a retraction from you would be appreciated.

Cold launch for HQ-9B needs extra bottom ejactor which could occupy more space than YJ-18 booster.

Doing a rough calculation by approximating both missiles as cylinders.
Brahmos: π x (0.3^2) x 8.4 ≈ 2.38 m^3
YJ-21: π x (0.42^2) x 8.3 ≈ 4.5m^3
So YJ-21 should be around 5670kg, around 1.9x the mass of BrahMos
5670kg seems a bit too high.
That's heavier then the missiles on the Slava class cruiser.

Wikipedia says the YJ-21 is 8.3 meters in Length
but
I can't find any site that lists the diameter of the YJ-21 missile.
I think we should be careful before jumping to conclusions about how heavy this missile really is.
I think 3,000kg is a safer and more conservative number. So I'll go with that for now....until I get more info.

Your repeated posts are nonsensical and seem to pathologically refuse to to actually engage in people's points and arguments. Feel free to take a break until you can learn.

You were away for one year as a warning already, so see you, never again.

A flotilla of the Chinese People's Liberation Army (PLA) Navy led by a Type 055 10,000 ton-class large destroyer has carried out a combat-oriented exercise in the South China Sea amid rising tensions in the region stirred up by the US.

Not targeted at a third party and aimed at safeguarding national security, the drills sent a signal that the US' provocative muscle-flexing against China will not work, experts said on Wednesday.

The Type 055 large destroyer Dalian, Type 052D destroyer Changsha, and Type 054A frigates Liuzhou and Yueyang attached to the navy of the PLA Southern Theater Command formed a flotilla and conducted a coordinated exercise in the South China Sea for more than 80 hours extending across four days and three nights, China Central Television (CCTV) reported on Tuesday.

Live-fire anti-ship, anti-aircraft and anti-submarine exercises were included in the drills, the CCTV report showed.

The drills honed the combat-oriented capabilities of individual ships and the flotilla as a whole, and laid a solid foundation for them to carry out flexible military struggles and enhance their capabilities to deal with emergency situations rapidly and properly, CCTV said.

The exercise was a routine one not targeted at any third party, but it was carried out against a complex geopolitical background in which the US recently rallied the Philippines and carried out the largest Balikatan joint exercise in the South China Sea targeting China, Chen Xiangmiao, director of the World Navy Research Center at the National Institute for South China Sea Studies, told the Global Times on Wednesday.

China's regular exercises could serve as a message that China will not compromise because of the US' provocative muscle-flexing and discord-sowing through military strength, and that countries should have dialogue and seek cooperation, Chen said.

The US is raising its military activities in the South China Sea from a tactical level, highlighted by frequent close-in reconnaissance operations, to a strategic level, like adding new bases in the Philippines and deploying advanced weapons like HIMARS rockets and Patriot missiles in joint drills, in an attempt to reinforce the first island chain and link such activities to the Taiwan question to deter China, observers said.

Unlike US moves that serve its hegemony and harm the regional situation, the PLA's routine drills are for the safeguarding of China's rightful interests, and they contribute to regional peace and stability, Chen said.

Earlier this month, the navy of the PLA Southern Theater Command announced that the Type 055 large destroyer Dalian had completed a

stretching for more than 8,000 nautical miles (14,816 kilometers) in the South China Sea and the West Pacific.

The latest exercise in the South China Sea means that the Dalian participated in consecutive, intensive drills, demonstrating its high combat readiness and reliability, analysts said.

It also showed that the PLA naval and aviation forces are fully capable of safeguarding national sovereignty, territorial integrity and development interests in the South China Sea, observers said.

An excerpt from a paper that I don't have access to. I'm therefore unsure about the context and how credible this is, but it states that a certain ship model (implied to be 055 by the illustration) has a beam of 21 meters, length of 180 meters, and a (total) height of 45 meters. The stated beam number of 21 meters is wider than the figure of 20 meters that is widely disseminated.
