Intended to engage low-flying targets on head-on and pursuit courses in clutter and IR jamming environments. The Igla system comprises a missile kept in a launch tube with a power supply source, a launch mechanism, training aids and maintenance facilities. The system features automatic input of lead and elevation angles, in-depth detonation of the warhead, detonation- capable propellant in the propulsion unit and a bias circuit in the homing head that ensures a hit at the most vulnerable target elements.
