The 9K34 Strela-3 man-portable air defence missile system (MANPADS) was developed in the Soviet Union as a response to the poor performance of the earlier 9K32 Strela 2 (SA-7 Grail) system. Its NATO reporting name is SA-14 Gremlin. The missile was largely based on the earlier Strela 2, and thus development proceeded rapidly. The most significant change was the introduction of an all-new infra-red homing seeker head. The new weapon was accepted to service in the Soviet Army between January 1974 and 1978.
