Sub-sonic cruise missile Nirbhav, with a range of 1,000km, is being developed by India for use in a wide variety of applications, according to a top military scientist.

Defence Research and Development Organisation chief VK Saraswat said the 1,000kg missile was “getting into some shape”, according to ptinews.com.

The trial flight of air-to-air missile Astra, with a range of 45km to 100km, is also on the cards, he said.

The scientific advisor to the defence minister said that the Indian armed forces were seeking long-duration loitering missiles that can enter enemy territory, identify targets and attack them.
