Its clearly cold launched. If the shorter missiles are cold launched, they are situated near the top of the VLS, with the tips of the missiles are just under the cover. This is similar to models of Redut missiles inside the UKSK VLS.
If the missiles are hot launched, the shorter missiles would be situated at the bottom of the VLS, with the rocket exhaust just above the transfer channel underneath the VLS.
Its safe to say its depicting U-VLS.
I suspect its related to this missile, or this is the land based version of it. Note that LY-80 is the HQ-16, LY-80N is the HHQ-16, LY-60 is the HQ-6 and LY-60N is the HHQ-6 used with the Jiangwei class. Its called the LY-70. Note the quad pack arrangement, along with the dimensions of a quad pack. This canister is also cold launched.
