Have you ever wondered how ballistic cum cruise missile like Shaurya survives the high aero-thermal loads experienced while flying at highly depressed trajectories (like a cruise missile) at hypersonic speeds of ~ 8 Mach ?
One way to deal with that is to ensure uniform heat distribution over the missile body (prevent sustained localised heating)
This is done by rolling the missile while inflight via deflection of rear fin in the tandem fins configuration which results in a corkscrew effect forcing the missile to roll
There is also a ablative coating which not only provides thermal protection but also reduces drag & increases range
This allows Shaurya to survive while flying low within the dense atmosphere like a cruise missile at high hypersonic speeds. Similar Tandem Fin configuration is also seen in SMART & PRALAY missiles
Which IMO implies that both SMART & PRALAY also posses the capability to execute (and survive) flight trajectories similar to ballistic cum cruise missiles (eg depressed trajectories) if so required
