According to defence sources, the surface-to-surface missiles mounted on mobile launchers were test-fired from the launch complex-3 in the ITR at around 8:15 a.m. and 9: 15 a.m.

The test-firing of the indigenously developed missiles were routine trials conducted by the personnel of Strategic Force Command (SFC).

The entire trajectory of trial was tracked by a battery of sophisticated radars, electro-optic telemetry stations and ships launched in the down range impact point area in the Bay for post-launch analyses.

Prtihvi-II, already inducted into the Indian Army, is capable of carrying warheads weighing 500-1,000 kg. It is equipped with an advanced inertial navigation system and has features to deceive anti-ballistic missiles.

During the last user trial from the same launch complex on September 24, the missile had failed to perform due to some technical problems.

The Prithvi-II has a strike range of 350 km and a two stage engine. It is nine metres long and a metre wide.
