The Prithvi-2 (only Prithvi version currently in active service) will be phased out within the end of this decade. For finding it's replacement, the IA/SFC had considered three different missile systems of various types :
1) The
PRAHAAR. A non-line of sight battlefield support missile (NLOS-BSM) with a 150km range and a 225kg payload of multiple types (HE, FAE, Incendiary, cluster munitions etc.), the principle use of this system (mounted in 2, 4 or 6-missile configurations respectively on 6x6, 8x8 and 10x10 high-mobility vehicles) was
area-saturation. Much like rocket artillery on steroids.
2) The
SHAURYA. A quasi-ballistic tactical battlefield missile with variable flight profiles (ballistic, lofted or depressed trajectories) and a minimum range of 750km. It was to be a weapon for attacking tactically-important targets like air bases, communication facilities, fuel & ammo dumps etc. from safe distances while being able to accompany an armored column if required. The missile was to be carried in a hermetically-sealed canister, much like the PLA 2nd Artillery Corps' DongFeng-16 and DongFeng-18 ballistic missiles that are deployed within Tibet Autonomous Region (TAR).
3) The
PRITHVI-3. A much-improved, solid-fueled version of Prithvi-2 (SS250). Shares the dimensions of the earlier missile in the family (with the exception of foldable control fins to facilitate canisterization) but removes the drawbacks of liquid-fuel, and makes use of all-composite stages reducing the missile weight and potentially increasing payload capacity as well as range, thanks to advancements in guidance technologies. Could have maximum ranges of around 600-700km and nearly a 1-ton payload capacity.

Given whatever sources I have available, the Prithvi-3 has been selected for production. The Army might never order the Shaurya although Prahaar still has hope in a different role to support artillery fire-assaults. But regardless, DRDO has already made the Prahaar a possible export prospect (hence the "Pragati" missile at the South Korean defence expo), while the Shaurya went on to serve as the basis for validating SLBM technologies in the guise of the K-15/B-05 SLBM.
