This test was conducted at the Pokhran Field Firing Ranges in Rajasthan. The tank target was placed at a range of 2500 metres. The Nag has, in other tests, successfully engaged targets at 4 kilometers and above.
For those who need reminding, the Nag is a Generation 3+ (the DRDO says Generation 4) fire-and-forget missile, which is being developed by the Defence Research and Development Laboratory (DRDL), Hyderabad. It is one of the five missiles being developed by India's Defence R&D Organisation (DRDO) as a part of the Integrated Guided Missile Development Programme (IGMDP). When the Nag is accepted into service by the army, the IGMDP will be formally closed.
The missile automatically conducts a top attack at ranges below 1300 metres. It has a tandem warhead that will defeat any Explosive Reactive Armour (ERA) in service today. The warhead has been developed by ARDE, Pune and HEMRL, Pune.
The Nag performed well during the summer trials in June 2007, which were conducted through the BMP-based NAMICA (Nag Missile Carrier). That is the vehicle in the video. Some glitches remained to be sorted out after the June 2007 trials. The army has asked for a higher level of ruggedisation (after one missile failed) and has also asked DRDL to improve user-friendliness: the display on the screens, fire controls and reduced reaction and aiming times.
The DRDL says it is confident that the summer trials in 2008 will validate all the technologies in the Nag. So far, one of the problem areas was in the missile's Imaging Infra-red Seeker, which homes it onto the target. That problem has been bypassed by importing the Focal Plane Sensor in the seeker from SOFRADIR in France.
Bharat Dynamics Limited (BDL) will be the prime contractor for construction of the missile. The production strategy involved getting even the development missiles manufactured by BDL.
The army has also asked for a helicopter borne version of the Nag, the HELINA (Helicopter Launched Nag) with a range of 7.5 km. That is slated to be fitted in the Light Combat Helicopter (LCH), which is being developed by Hindustan Aeronautics Limited (HAL) Bangalore.
