Nag is India's third generation "Fire-and-forget" anti-tank missile. It is an all weather, top attack missile with a range of 3 to 7 km.
The missile uses an 8 kg tandem HEAT warhead capable of defeating modern armour including ERA (Explosive Reactive Armour) and composite armour.
Nag uses Imaging Infra-Red (IIR) guidance with day and night capability.
Nag can be mounted on an infantry vehicle; a helicopter launched version will also be available with integration work being carried out with the HAL Dhruv.
