YJ-12

The YJ 12 shown here looks to be a version made for the new VLS system seen on the 52D going by the square enclosure not needed for air launched versions.

An type 52D could potentially carry 64 of these mach 5 400 km range missiles.

Though it seems a larger dedicated version called the YJ 16 is intended to use the full 9 meter by 850mm capacity of the new VLS on the 52D.

The fact that most of the ramjets today have to slow down the incoming air to subsonic velocities limits the speed of any missile of this kind to reach with efficiency Mach 4.

Considering the size and the current level of applicable technology in the world, if the weight of YJ-12 is between 2 to 2.5t, the speed should be around Mach 2 (low altitude) to Mach 3.2 (high altitude) with a range from 250 to 350km.

Not necessarily. The Indian/Russian military is acquiring a Mach 7 variant of their BrahMos with extended range as well. And then we have the Mach 4.5-capable YJ-91 with a range of 110 km.

He also mention weight. More or less I think YJ-12 will fall in this category too, like if weight reduction achieved than low rage or low velocity, vice-versa.

Ramjet is absolutly not efficient in > Mach 6, more than this speed the incoming air will completly stop the combustion in the chamber.

To go faster we should need scramjet, but no any country in this world has made significant progress in this area...

The BrahMos and YJ-12/18 are sea skimming, which means that the actual speed will not be as detrimental as they are in the high atmosphere, especially when you can control the size of the intakes and thus the volume flow rate of air.

It's not a matter of volume flow but to maintain the incoming air in subsonic speed when entering into the combustion chamber. If the missile flies faster than Mach 5 to 6, whatever the inlet's form the incoming air could not be slowed down to subsonic speed and the propergol mixed with this air will not have enough time to burn before being exhausted, and this will decrease the efficiency of the engine.

The most efficient working speed zone is between Mach 3 and 6. Higher than this you must go to scramjet technology.

That's the physical reason for why any missile working with ramjet can't exit Mach 6. After that the range is just a matter of how many propergol (solid or liquid, or mixed) you bring in your missile, bigger it is, farer you go.

How many YJ12 052D could carry at once?

YJ-12 is an air-launched supersonic missile which is developed to replace the YJ-83K。

YJ-18, capable of both torpedo-launch on a sub or vertical-launch on DDGs, has been developed to replace the YJ-8 series and the YJ-62.

052D is reportedly armed with 8 YJ-18As。
 
I am absolutely enjoying the conversation over here @sino soldier

Hmm... you do have a point. However, I think it is possible for the fuel to be combusted after it exits the combustion chamber; the effect and result should be the same. And like you said, the efficiency of an engine like that runs from Mach 3-6; well, the YJ-12 and YJ-18 are rumored to be Mach 4 and Mach 5, respectively, which fall into that range. The Russo-Indian BrahMos II is said to have a scramjet engine.
 
YJ-22 is powered with a scramjet engine, perhaps in the class of Mach 7.
