Nag (Cobra) anti-tank missile

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 a third generation anti-tank missile system with "fire and forget" and "top attack" capabilities. Capable of defeating modern armour, Nag uses Imaging Infra-Red (IIR) guidance having both day and night capability. The state-of-the-art Imaging Infra Red homing guidance system has lock-on-before-launch capability for day and night operation.

A smokeless nitramine based propellant has been developed for the Nag. The missile is carried either on "NAMICA" (Traced ICV) or the Advanced Light Helicopter. Its high strength composite airframe with foldable wings and fins, onboard real time processor with fast and efficient algorithms, compact sensor package and electric actuation system, digital autopilot and high immunity to counter measures, make this a formidable missile.

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.

As of 1998 18 flight trails had been conducted, though it had yet to enter the production/induction phase. Two Nag missiles were launched satisfactorilyJune 21, 2002 at 1015 hrs and 1300 hrs from Interim Test Range, Balasore. The trajectory of both trials was fully tracked through out the flight and telemetry data has been received. These were the 43rd and 44th test launches of the Nag missile.
