But the missile of entirely new design with substantially improved range and speed,. The new seeker and aerodynamic improvements extend its effective range, and its higher speed enables it to be used against faster targets. The SA-18 has a maximum range of 5200 meters and a maximum altitude of 3500 meters. The 9M39 missile SA-18 employs an IR guidance system using proportional convergence logic. The new seeker offers better protection against electro-optical jammers; the probability of kill against an unprotected fighter is estimated at 30-48%, and the use of IRCM jammers only degrades this to 24-30%.
The Igla-M [SA-N-10 ] is the naval version of the SA-18.
