Multi-barrel rocket system 'Pinaka' was on Thursday successfully test-fired twice at Chandipur-on-sea, about 15 km from Balasore.
The trials took place at the Proof and Experimental Establishment (PXE) at 2.30 pm And 3.05 pm, defence sources said.
Developed by the Defence Research and Development Organisation (DRDO), Pinaka is an area weapon system aimed at supplementing the army's existing artillery gun with a range beyond 30 km.
Its quick reaction time and high rate of fire provides the army an edge during low-intensity war-like situations.
The unguided rocket system put under trial here could be used to neutralise a higher geographical area with its salvo of rockets, the sources said.
With a range of 39 km, Pinaka can fire a salvo of 12 rockets within 44 seconds.
