Also incorporated into the guidance system, is a CCD camera. The missile has a weight of 42 kg and can engage targets at ranges up to 6 km. The Nag will be produced in two main versions. The carrier is a stretched BMP-2 with an additional pair of road wheels and is manufactured by the Ordnance Factory, Medak. With the IR version of the missile, targets are acquired using a thermal sight, and are then assigned to the nose-mounted IIR seeker.
Missile guidance is initially by area correlation around the target, then by centroid tracking.
Eight missiles are carried in two quadruple launchers. A Nag being test-fired. Despite trials since 1990, problems with the guidance system held back successful trials for a long time. The IIR version of the missile has undergone several rounds of successful flight trials since 1997. The development of the mmW seeker has been more problematic and it is unlikely that the seeker will enter service any time soon.
