Nag is a third- generation "fire and forget" anti-tank guided missile with a range of 4 to 6 kilometers. Nag can be mounted on an infantry combat vehicle and helicopter launched version of Nag is also available. Nag is India's third generation anti-tank missile, having an all weather capability. Capable of defeating modern armour, Nag uses Imaging Infra-Red (IIR) guidance having both day and night capability. As of 1998 18 flight trails had been conducted, though it has yet to enter the production/induction phase.
Both Army and Air Force versions are being tested separately. For the Army, the missiles will be carried by specialist carrier vehicles equipped with a thermal imager for target acquisition. It can carry tour missiles at a time. For the Air Force, a nose-mounted thermal imaging system has been developed for guiding the missile's trajectory. A twin launcher for the Advanced Light Helicopter and a single launcher for Cheetah helicopter have also been successfully developed.India's Integrated Guided Missile Development Program (IGMDP) was launched in July 1983. Initially, it had a budget of around Rs 400 crore, but it has since been revised Rs 800 crore. The major programs under the IGMDP are the development of missiles including Agni, Prithvi, Akash, Trishul and the Nag. The Sagarika and the Surya have since been added to the IGMDP.
