My dream for Indian artillery and rocket force to have medium MLRS like SR5 and heavy MLRS like PHL16.
We are a quarter way there with Pinaka, just need to make ATACMS like missile for it and dedicated loitering munitions. Probably need to work on making it self sufficient to work in single unit mode instead of whole battery to reduce signature on battlefield just like mobile launcher for Pralay where comms are integrated within launch vehicle.
We are yet to see the appeal of a heavy MLRS especially for rocket force and haven't even seen some kind of project in this field.
