DRDO has test fired its indigenously developed, fire-and-forget anti-tank missile, Nag. It successfully hit the target 4 km away during a night trial in the Mahajan Field Firing Range, Rajasthan. DRDO used the Thermal Target System (TTS) developed by a defence laboratory at Jodhpur as target for the missile during the test fire of Nag anti-tank missile. Thermal Target System (TTS) imitated the target similar to operational tank. This was possible as thermal mapping from tank to TTS was carried out for generating thermal signature.

After this trial DRDO stated that Nag missile is now ready for final, pre-induction user trials. This anti-tank missile Nag uses HEAT (High explosive anti-tank). It can destroy modern tanks with armoured protection by nullifying their ERA (explosive reactive armour).

 NAG 

• Nag is a third generation fire-and-forget, anti-tank missile developed in India.
• It is one of five missile systems developed by the DRDO under the Integrated Guided Missile Development Program (IGMDP).
• This anti-tank missile, Nag is equipped with Imaging-Infrared seeker which will help in guiding the missile to its target after its launch.
• The Nag is claimed to be the first anti-tank missile which has a complete fiberglass structure. It can engage targets in the range of 4–5 km.
