Nag Anti Tank Missile,3rd Generation Missile System,IGMDP,Indian Armed Forces

Nag is a third generation Fire and Forget anti tank missile developed by Defence Research and Development Organisation (DRDO),India under the Integrated Guided Missile Development Program (IGMDP).It is manufacuted by Bharat Dyanamics Limited (BDL) and in service from 2015 in Indian Army.

The missile is based on Lock on before launch and after launch(HELINA) Top Attack mode;It works on fire and forget principle.The single shot hit probability of the Nag missile is 77%. Nag has been developed at a cost of ₹3 billion (US$45.3 million).


The Indian Army has placed an order of 443 Nag missiles and 13 Namicas for introduction in the next 3 years.Nag will be the first weapon of such kind that will be inducted into the army by November–December 2009. The Army urgently needs the more advanced Nag to improve kill probability as the missile using a high explosive warhead to penetrate the armor in modern tanks.

Nag has successfully completed its final validation trials and is expected to join the Indian Army in 2011.Two missiles were launched against a moving target at a time another two missiles were launched against a stationary Vijayanta tank in quick succession and successfully hit the targets. Indian Army is happy with the performance and is expected to buy 443 missiles for ₹3.35 billion.

450 Nag missiles along with 13 NaMiCA carriers were to be inducted into the Army’s arsenal by 2011 with the successful completion of final validation trials in Rajasthan, however, this may now take some more time after the missile’s failure in the user validation trials.The Army also projected in their perspective plan the need for 7000 Nag missiles and around 200 NAMICAs.

Design and Features

Nag Anti Tank Missile,3rd Generation Missile System,IGMDP,Indian Armed Forces

NAG is the first missile with complete fiberglass structure

The Anti tank Nag missile has a length of 1.90 m (6 ft 3in),Diameter of 190 mm(7.5 in) and wingspan of 400 mm.The weight of missile is 42 kg and it can carry tandem warhead of 8kg.

The Nag is claimed to be the first missile which has a complete fiberglass structure.

Engine and Performance

The 3rd Generation NAG anti tank missile is powered by Rocket motor Tandem Solid propulsion (nitramine based smokeless extruded double base sustainer propellant).Generally missiles leave plume as the missile heads towards the target which makes it harder for the firer to remain hidden but in the case of Nag missile however ,the plume is visible only first one second then after when the missile maintains its speed it release the smokeless propellent that is almost invisible which makes it most dangerous weapon.

The missile can fly with the speed of 230 metres per second.It has operational range of 500m to 4km (land version) and 7-10 km (Air-launched version).The Missile has a single shot probability of 77% and a CEP of 0.9 metres.It has a 10 year maintenance free shelf-life.

Guidance and Navigation System

As originally conceived, the Nag would have been available with three different types of guidance, a wire guided version(a missile that is guided by signals sent to it via thin wires connected between the missile and its guidance mechanism, which is located somewhere near the launch site.), an infra-red version (the missile uses the infrared (IR) light emission from a target to track and follow it.) and a millimetric wave (mmW) active radar homing version(In this a missile contains a radar transceiver (in contrast to Semi-active radar homing, which uses only a receiver) and the electronics necessary for it to find and track its target autonomously.).

But DRDO failed to develop a wire guidance system leading to plans for this being dropped. Currently, guidance is based on an imaging infrared (IIR) passive seeker that ensures a high-hit accuracy in both top- and front-attack modes.

The mmW seeker is intended to operate as an optional system that can replace the IIR passive seeker as a module.There is also a CCD camera integrated into the guidance system.Optical seeker proves more useful as it is less prone to jamming. Missile guidance is initially by area correlation around the target, then by centroid tracking. Terminal homing is by area correlation around the centroid.

The missile does not follow a completely parabolic path like conventional projectiles. It moves near the target in a parabolic path, then rises upwards suddenly and then bends at a steep angle and hits the target.

Launch Platforms and Basic variants

The missile is basically is launched from three platforms;NAG Missile Carrier (NAMICA),HAL Dhruv Helicopter and HAL Light Combat Helicopter.

The NAG will be produced in two basic bariants;land version and Air launched version. The land version has been tested from a tracked vehicle known as NAMICA (Nag Missile Carrier). With the IR version of the missile, targets are acquired using a thermal sight, and are then assigned to the nose-mounted IIR seeker.

The Air Launched version will be used on the Advanced Light Helicopter(ALH) and the HAL Light Combat Helicopter(LCH). This version will be known as HELINA (HELIcopter NAg).

Advanced Variants

HELINA (Helicopter Nag)

HELINA, helicopter  launched Nag  version with a range of 7-8 km.The missile is launched from the twin-tube stub wing-mounted launchers on board the armed HAL Dhruv and HAL light Combat Helicopter produced by (HAL) Hindustan Aeronautics Ltd India. . Eight missiles are carried in two quadruple launchers. Launchers mounted on either side are linked to a nose-mounted stabilized thermal sight and a laser rangefinder package.

This version of  missile is structurally different from the Nag. The Helina will make use of an IIR seeker for target engagement like the Nag. Launchers have been cleared for captive carriage trials and handed over to Hindustan Aeronautics Limited (HAL) for carriage trials.

HELINA was tested to its full 7 km range in 2014 after being fired from an ALH Dhruv helicopter.The missile is based on  ‘lock-on after launch’ system extending its range to 7 km. In this scenario, the missile is launched in the general direction of the target. As it approaches the target, images of the area ahead are sent back to the operator who will be able to identify enemy tanks. The command to lock on to a tank is then passed onto the seeker through an uplink mid-flight. After that, the missile homes in onto the target and destroys it.

Land Version

In this Land version the range of Nag missile is extended to 7-8 km with the development of mast-mounted missile launcher that will be hydraulically raised out to a height of five metres to enable the Nag missile to cover more distance to acquire its targets.

Air-Launched Version

In this Air-launched version the range of Missile is extended to 10 km and it is Launched from tactical interdiction aircraft like the upgraded jaguar IS. It will use a nose-mounted millimetric-wave active radar seeker.

Man Portable version

Future of NAG Missile

Defence Research and development laboratories (DRDL)  will also start working on the Man Portable Nag very soon.It would weigh less than 14 kg and easily be carried by man.There is no need to launch the missile from proper platform.

4)NAMICA Nag Missile carrier

Namica Nag missile carrier

NAMICA (Nag Missile Carrier) is a tank destroyer built for the army. It is equipped with a thermal imager for target acquisition. NAMICA is a modified BMP-2 ICV produced as “Sarath” in India. The carrier weights 14.5 tonnes in full combat load and is capable of moving 7 km/h in water. The carriers are capable of carrying 12 missiles with 8 in ready-to-fire mode. The NAMICA carrier was put through transportation trials covering 155 km during 2008 summer trials.

The NAMICA version of the missile is a ‘lock-on before launch’ system, where the target is identified and designated before the missile is launched. As the targeting system is based on visual identification, the range is limited in this case approximately from 500 m to 4 km.Continue Reading NAMICA NAg missile Carrier
