Yeah. But it is being developed. Last time I say doc regarding UVLS they were going with a twin configuration. A smaller UVL cell for hot launching smaller missiles like SAMs & a larger cold launched UVL cell for bigger missiles like Brahmos, ET-LDHCM, LR-AShMs etc.
The problem with this approach is that some larger missiles like Kusha M2, M3, AD-1, AD-2 etc. need to be hot launched. SAMs of any range should preferably use hot launch, that allows them to preserve momentum & climb faster.
So, we will need not 2 but 3 types ULV cells. Smaller hot-launch, large hot-launch & large cold-launch. DRDO is trying to see if they can quad-pack smaller SAMs from the large hot launch VLS.
Again, the problem here is that Navy's current hot launch SAM, Barak-8, is a bit smaller than the Kusha M1. There are compatibility issues which will need to be resolved. Unless the Navy wants to abandon the Barak-8 entirely, I don't think they do.
