India's state-of-the-art anti-tank missile 'Nag' has been successfully test fired for the first time from a vehicle, a defence official said in Hyderabad.

The missile was fired from BMP-II vehicle and scored a direct hit at a target 2 km away, Nag Project Director S S Mishra said.

The test took place on June 10, he said.

This is the 40th test of the fully assembled 'Nag' and the first from a platform that will be used in a battle, he said.

Previous test had taken place from make-shift launchers.

Mishra said it was also the first missile to be test fired from the Shamirpet firing range near Hyderabad. Earlier tests were performed at Ahmednagar.

Equipped with an infra-red homing sensor for day and night operation, the fire-and-forget missile can destroy a tank four kilometre away by diving into the tank from the top.
