well Helina should be tested by end of this year or early next year, reportedly has a range of 8-10km, should be deployed on the Dhruv, LCH, M-17s, Future Apaches etc. We need to get the Apache block 3 and also get the laser guided Hydra 70 with a range of 12 km as well.

8km to 10km is too high range for IIR seeker what we may expect is 6km to 7km with IIR seeker. 10km range is for MMW seeker.
We aren't going to buy appaches.

I think the tender for tyhe 22 Attack helicopters has been re-issued. Apache is one of the contenders. Only Bell pulled out their super cobra.

Army opts for Nag missile as it enters final trials

In Rajasthan, this May, the indigenously developed Nag (Cobra) missile will undergo a final round of trials before entering service in the Indian Army’s arsenal. Developed by the Defence R&D Laboratory (DRDL) in Hyderabad, the army is delighted with how the Nag has performed in a series of earlier trials. A senior army officer calls it, “the world’s deadliest anti-tank guided missile (ATGM).

Indian infantry formations urgently want a potent ATGM to handle Pakistani tank forces that now bristle with capable Ukrainian T-80 and Chinese T-85 tanks.

So confident is the army about the Nag that, even before trails are completed, it has budgeted Rs 335 crores for buying 443 Nag missiles, which will be manufactured at the public sector Bharat Dynamics Limited. The missiles will equip Reconnaissance and Support Battalions, mechanised units that locate and destroy enemy tanks.

In trials last summer six Nag missiles were fired at tanks 3-4 km away; each of them hit their target precisely. Next month the Nag must demonstrate its capability at its minimum range of 500 metres.

“Since the Nag travels at 230 metres per second, it has just 2 seconds to align itself to a target that is 500 metres away. But we are confident that the Nag will meet this requirement during the forthcoming trials”, the DRDL’s Officiating Director, Amal Chakrabarti, told Business Standard during a visit to the Hyderabad missile complex.

The Nag is a third-generation (Gen-3), “fire-and-forget” missile; once it is fired, its seeker automatically guides the missile to even a fast-moving tank. In earlier-generation missiles an operator had to guide it all the way, often exposing himself to enemy fire. The world has just a handful of “fire-and-forget” missiles, such as the American Javelin, and the Israeli Spike. The Javelin and the Spike are lighter missiles that can be carried by a soldier; the Nag is a heavier and more powerful missile designed to operate from vehicles and helicopters.

While the infrared seekers of the Javelin and the Spike can be jammed, the Nag’s optical guidance system makes it virtually jam-proof. The indigenous development of an imaging seeker, a highly complex and closely guarded technology, is the Nag’s greatest triumph.

Here’s how it works. Nag missile operators search for enemy tanks through thermal imaging telescopes, which see as well by night as they do by day. Picking up a tank, the operator locks the Nag’s seeker onto the target. A digital snapshot of the target is automatically taken, which serves as a reference image. As the Nag streaks towards the target, at 230 metres per second, the seeker takes repeated snapshots of the target; each one is compared with the reference image, and deviations are translated through on-board algorithms into corrections to the Nag’s control fins, which steer the missile precisely at the target.

This method of firing is termed “lock-on before launch” or LOBL. In the pipeline is an even more sophisticated method --- “lock-on after launch” or LOAL --- for the helicopter-mounted Nag, or HELINA, which can target a tank 7 kilometres away. Since the target will seldom be visible at such a distance, the missile operator launches the HELINA in the general direction of the target. As it flies towards the target, the Nag’s seeker downlinks to the missile operator images of the area ahead; after travelling 3-4 kilometers, i.e. after about 12-16 seconds, the operator will be able to identify enemy tanks. He will lock the seeker onto the tank he wishes to destroy, and the command will be uplinked to the missile in mid-flight. After that, the missile homes in onto the target and destroys it.

The Nag provides its operator with another important tactical advantage. The plume of burning propellant from the tail of most missiles gives away its flight path and allows the target to get behind cover. The Nag, in contrast, is visible only during the first one second of flight, when the missile’s booster imparts 90% of the momentum; after that, a sustainer maintains the missile’s speed, burning a smokeless propellant that is practically invisible.

Acceptance of the Nag missile into service will be a triumphant conclusion to the Defence R&D Organisation’s (DRDO’s) long-delayed, but eventually successful, Integrated Guided Missile Development Programme (IGMDP). Initiated in 1983 by then DRDO boss, Dr APJ Abdul Kalam, the IGMDP set out to develop five missiles: the Agni and Prithvi ballistic missiles; the Akash and Trishul anti-aircraft missiles; and the Nag ATGM. Only the Trishul will have failed to be accepted into service.

Indian Army to test fire Nag missile in May


NEW DELHI (BNS) The Indian Army is gearing up to test fire the indigenously-built Nag anti-tank missile from Rajasthan in May.

The short-range missile, developed by Hyderabad-based Defence Research and Development Laboratory (DRDL) under the Integrated Guided Missile Development Programme, will be inducted in the Army after completing the final round of test trials, sources said.

The Army has earmarked Rs 335 crore to buy 443 Nag missiles.

Nag is a third generation missile which operates on the “fire-and-forget” formula.

While the land version of the missile has a range of 4 to 6 km, its air version has a range of 7 to 8 km.

The 42-kg missile can fly at a speed of 230 meters per second.

Final trials are on, this time at Rajasthaan in May. Building on what Saya said about low-end range testing, next month's trial will involve testing the missile at its minimum range of 500 m - which, for a "fire and forget" missile that travels at 230 m/s, leaves it with barely over 2 secs to align itself with a target 500 metres away.

The Army is evidently very pleased with it- a first of sorts- with one official even cailling "it the world's deadliest anti-tank guided missile (ATGM)". The Army is doubly pleased with it because it utilizes a 3-dimensional, optical enhanced mmW seeker (in some variants) as also an IIR seeker in other variants, which in contrast to the infrared seekers employed on other man-portable fire 'n' forget' missiles like the Javelin and Spike, provides high resolution, all weather capability and high immunity to current conventional countermeasure techniques. The satisfaction is evident from the R.335 crores the Army has set aside for buying 443 Nag missiles.

Here's a lil' run-down of how the Nag-missile works:



How it works

Here's how it works. Nag missile operators search for enemy tanks through thermal imaging telescopes, which see as well by night as they do by day. Picking up a tank, the operator locks the Nag's seeker onto the target. A digital snapshot of the target is automatically taken, which serves as a reference image.

As the Nag streaks towards the target, at 230 metres per second, the seeker takes repeated snapshots of the target; each one is compared with the reference image, and deviations are translated through on-board algorithms into corrections to the Nag's control fins, which steer the missile precisely at the target.

This method of firing is termed "lock-on before launch" or LOBL. In the pipeline is an even more sophisticated method -- - "lock-on after launch" or LOAL -- - for the helicopter-mounted Nag, or HELINA, which can target a tank 7 kilometres away. Since the target will seldom be visible at such a distance, the missile operator launches the HELINA in the general direction of the target. As it flies towards the target, the Nag's seeker downlinks to the missile operator images of the area ahead; after travelling 3-4 kilometres, i.e. after about 12-16 seconds, the operator will be able to identify enemy tanks. He will lock the seeker onto the tank he wishes to destroy, and the command will be uplinked to the missile in mid-flight. After that, the missile homes in onto the target and destroys it.

The Nag provides its operator with another important tactical advantage. The plume of burning propellant from the tail of most missiles gives away its flight path and allows the target to get behind cover. The Nag, in contrast, is visible only during the first one second of flight, when the missile's booster imparts 90% of the momentum; after that, a sustainer maintains the missile's speed, burning a smokeless propellant that is practically invisible.
Now the Indian army needs to fast track the operational clearance and impetus should be given to the speedy development of HELINA.
I can't confirm this, but I'm hearing "rumours" about talk on the grapevine of developing Helina into an all round CAS weapon, mounted on both helicopters as well as on fighter jets- which may be the reason for its delay. 'Course, the obvious other reason is issues with the seeker and guidance, as Helina makes use of the "Lock on After Launch" (LOAL)- a more 'sophisticated' method than the "Lock on Before Launch" on the Nag. Although one scheduled trial of the Helina was due to take place in 2009 (the end), anybody know if that ever did actually happen?

Nag : Deadliest anti-tank guided missile in the world


In Rajasthan, this May, the indigenously developed Nag (Cobra) missile will undergo a final round of trials before entering service in the Indian Army’s arsenal.

India's Nag missile completes final validation test



NEW DELHI (BNS): India's indigenously developed anti-tank missile Nag has successfully completed its final validation trials and is expected to join the Indian Army in 2011.

The missile underwent its 'final' trials in Rajasthan's Chanan Air Force ranges on Wednesday during which a total of four Nags were fired in quick succession against both fixed and moving targets, The Hindu news daily reported quoting a DRDO official.

While two missiles were launched against a moving target at a time, two others were directed against a derelict Vijayanta tank, the official said, adding that the 'fire-and-forget' missile "was bang on target."

The group of missiles was fired to cover varying ranges of 500 meters to 2,600 meters and "caused extensive damage to stationary Vijayanta tanks on both the occasions," the official said.

The official exuded confidence that the missile would be inducted in the Indian Army by early next year as "the Army was satisfied with the performance of the missile."

The short-range Nag missile has been developed by Hyderabad-based Defence Research and Development Laboratory (DRDL) under the Integrated Guided Missile Development Programme of India.

A third-generation missile, Nag operates on "fire-and-forget" principle. While the land version of the missile has a range of 4 to 6 km, its air version has a range of 7 to 8 km. The 42-kg missile can fly at a speed of 230 meters per second.

Indian Army has earmarked Rs 335 crore to buy 443 Nag missiles.

Meanwhile, the NAMICA (Nag Missile Carrier) which will carry eight Nag missiles in 'ready-to-fire' mode, underwent floatation trials in the Indira Gandhi Canal, Nachna (Rajasthan) on Thursday during which the entire system manoeuvred through the canal and established its "channel-crossing ability," The Hindu said.

Nag Man Portable ATGM Program goes on backburner
BY IDRW ADMIN

BY: Vinayak shetty

Recent agreement to purchase Third Generation American made Man portable Javelin anti-tank guided missiles (ATGM) as a replacement for Second Generation French Milans might be a death blow to Nag Man portable version of ATGM which DRDO wanted to build locally in India.

DRDO in 2006 had announced its intention to built a 14kg `Man Portable' Nag , Work has been going for a while and after Nag had successfully completed its final validation trials and orders placed by army for 443 missiles for Rs 335 crore.

DRDL was expecting Army to wait for Man Portable Nag to be ready to be offered to them since Recently Army had placed orders for 4100 new Milan ATGM which has been produced in India, under license from European firm MBDA, over the past 30 years, Sudden purchase might put whole program into back burner since Army has not cleared its intention regarding Nag Man Portable version yet .

Army Sources are confident that Javelin ATGM is only interim purchase to induct new generation ATGM into the force and NAG man portable version when ready and after validation will be inducted into army .

The Javelin, introduced in 2002, weighs 22.3 kg (49 pounds, with disposable launch tube and battery/seeker coolant unit) and is fired from a 6.4 kg (14 pound) CLU (command launch unit). The CLU contains a 4x day sight and a 9x heat sensing night sight. The missile has a tandem (two warheads, to blast through reactive armor) that can hit a target straight on, or from the top. This latter capability enables the Javelin to destroy any existing tank (including the U.S. M1) with its 8.2 kg (18 pound) warhead. Maximum range is 2500 meters.

This was expected after the purchase of JAVELINS. I hope HELINA does not suffer the same fate.

How can Nag go when there is no comparison in what a javelin does and what a Nag does. Man portable vs tank or heli mounted.

Yusuf why double the cost of weapons by having an indigenous program that spends years and bilions to develop weapons only to be rejected and spend billions more to buy from a foreign source?? I don't think the talk of HELINA on LCH will materialize either.
