PLAN Anti-ship/surface missiles

The "air intake" near the nozzle almost for sure housed the motors and actuators of the tail fins for directional control.

Doesn't take a lot of imagination to consider a plausible reason why it looks like the air intake continues to the bottom.

Cost ? The mock up constructors didn't gain actual access to build the mock up? Mis-information?
Could be all above or none of them.

All good ideas, but we've had enough pictures of what YJ-12 looks like from actual test articles (see first two pictures of my post 160) and other sources to know that the mock ups are quite accurate in that respect. (What they lack are the tail/booster extensions seen on the test articles). So the likelihood of it being your suggested answers are unlikely.

In that case, it becomes not a question of "are the mock ups representative of the actual missile" and "why could the actual missile feature these design features".

There are other missiles which feature similar design intake "extensions" btw: XASM-3's air intake structures extend all the way back to the nozzle as well, as well as the GQM-163 target drone, and the aforementioned Kh-41, and Kh-31 as well.

To clear the doubt of our friend, here is the actual photo of YJ-12, with boaster rocker attached to its tail (on the upper photo).

Possible estimate a size, weight ?

You need to pay more attention to details. Here is a picture of what you say is the XSAM-3.




As you can see the intake is actually integrated to the body of the projectile around mid-way.
By the way this is not the actual XSAM-3, this is only a test bed to see if the scram jet actually work as designed. TRDI never actually announced the XSAM-3 yet.

If those pictures are the actual missile then I have doubts that the scram jets would work as designed since it would be extremely difficult to regulate the air flow to the scram jet with that design with probably a deflector within the rectangular pipe.

The YJ-12 (, ) looks a bit like the

Here is the Kh-31 and P-270 for comparison:

Interesting comparison of the YJ=83 and YJ-12 I received via email.

The YJ-12 is a very large missile...looks to be, according to my friend's estimate, about 7 meters long (without the booster) and 0.50 meters in diameter.

And here is a static display of a YJ-12 on a J-15. I have to emphasize that I believe that this is a mockup...but it shows it just the same.



As I say...big missile.

Nonetheless clearly less big as the Brahmos or SS-N-26, 8.4/8,9 m, diam 0.6/0.7 m, 3 t.
