Indian Army Nag vs US Army FGM-148 Javelin |Anti Tank Missile Comparison|Controversy

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.

Whereas the FGM-148 Javelin is an American man-portable fire-and-forget anti-tank missile fielded to replace the M47 Dragon anti-tank missile in US service.The Javelin is considered the world’s best shoulder fired anti-tank weapon and 12 nations currently operate the Javelin under foreign military sales from the US.

Design And Features Compared

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.

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). .It has a 10 year maintenance free shelf-life.

Where as the FGM-148 Javelin has a length of 1.1 m,Diameter of 127mm and weight of 22.3kg.IT can aso carry Tandem Shaped Charge HEAT warhead weighing 8.4 kg.It  is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a top-attack flight profile against armored vehicles ,but can also take a direct-attack mode for use against buildings. This missile also has the ability to engage helicopters in the direct attack mode.

The Missile has great effect on impact.The missile’s tandem shaped charge warhead is made to penetrate reactive armor. With the top attack mode, it has an even greater ability to destroy the tank because it can attack where most tanks are weakest.

Launch Platforms

Indian Army Nag anti Tank Missile is  basically is launched from three platforms;NAG Missile Carrier (NAMICA),HAL Dhruv Helicopter and HAL Light Combat Helicopter. Defence Research and development laboratories (DRDL)  ,India 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.

Whereas the US Army FGM-148 Javelin is carried by a two-man team consisting of a gunner and an ammo bearer, although it can be fired with just one person if necessary. While the gunner aims and fires the missile, the ammo bearer scans for prospective targets, watches for threats, such as enemy vehicles and troops, and ensures that personnel and obstacles are clear of the missile’s back blast.

The missile is ejected from the launcher so that it reaches a safe distance from the operator before the main rocket motors ignite; a “soft launch arrangement”.

Engine and Propulsion

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.

Whereas  the Javelin system uses a soft launch mechanism. A launch motor using conventional rocket propellant ejects the missile from the launcher, but stops burning before the missile clears the tube. The flight motor is ignited only after a delay to allow for sufficient clearance from the operator.

The launch motor uses a standard NATO propellant, the presence of lead beta-resorcinol as a burn rate modifier causes an amount of lead and lead oxide to be present in the exhaust; for this reason, gunners are asked to hold their breath after firing.

The NAG anti Tank 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 whereas on the other hand the Javelin can reach a peak altitude of 150 m (500 ft) in top-attack mode and 60 m in direct-fire mode.It has a operational rane of 75 to 2500 m.

Guidance and navigation System

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.).

Whereas the FGM-148 Javelin is equipped with an imaging infrared seeker.The missile has to be able to track and destry its target without the gunner.This is done by coupling an on-board Imaging IR system with an on-Board tracking system.

The CLU’s thermal imaging system of Javelin may hinder aiming, its thermal targeting allows the Javelin to be a fire-and-forget system. This gives the firer an opportunity to be out of sight and possibly moving to a new angle of fire, or out of the area, by the time the enemy realizes they are under attack. This is much safer than using a wire-guided system where the firer must stay stationary to guide the missile into the target.
