Pinaka Mk-III is currently in advanced development. This enhancement of the Pinaka system turns the ballistic rocket into a precision weapon, using guidance, navigation, and control (GNC) placed in the empty ogive section of the warhead. The system uses INS (MEMS-based) and three-level satellite navigation support – GPS, GAGAN, and GLONASS. The system employs vector explicit guidance algorithms to guide the rocket using aerodynamic canard controls that increase the rocket precision, providing hit accuracy of less than 30 m at its maximum range. The Indian Army plans to use Pinaka Mk III to replace the 26 long-range
artillery rocket battalions currently using the Russian BM-30 Smerch 300mm rocket launchers. According to DRDO the system, likely to complete development in 3 years. Each rocket has a length of 5.175 m and a diameter of 214 mm. Weighing 325 kg, Pinaka Mk III has an effective range of 20-80 km. It carries a warhead of 100 kg (including the 23 kg guidance system).
