Missile 9K32M Strela-2 (SA-7 Grail)
Description
The 9K32 Strela-2 originated in the Soviet Union following a shift in defense policy to address gaps in mobile battlefield air defenses. While initially intended to counter high-altitude threats, the requirement evolved into a multi-tier system including a battalion-level man-portable component. The design incorporated elements from the US FIM-43 Redeye. The initial 9K32 variant entered service in 1968, followed by the improved 9K32M Strela-2M in 1970.
The system is a shoulder-launched surface-to-air missile utilizing passive infrared homing. The seeker employs an uncooled lead sulfide detector and an amplitude-modulated spinning reticle for target tracking. It operates on proportional navigation logic to intercept targets. Because the seeker detects energy in the near-infrared spectrum emitted by hot surfaces, engagement is generally limited to the rear hemisphere of jet aircraft. The 9K32M variant introduced an automated gripstock to simplify firing sequences and utilizes a higher thrust propellant. The missile is equipped with a directed-energy blast fragmentation warhead containing a high-explosive charge in a pre-fragmented casing. Detonation is triggered by impact or grazing fuzes, with an internal self-destruct mechanism that activates if the target is missed.
The system was produced in large quantities and has been widely deployed, forming the backbone of short-range air defense for numerous nations. It has been exported to several countries and provided to various insurgent and revolutionary movements. Combat use began in 1969 during the War of Attrition, followed by the Yom Kippur War. In the Vietnam War, the system was used against helicopters and propeller-driven aircraft. During the Soviet-Afghan War, it was employed by Mujahideen forces. In 1991, an Iraqi soldier used the system to shoot down an American AC-130H gunship. The missile has seen service in the Yugoslav Wars and more recent conflicts including the Syrian Civil War and the Russian invasion of Ukraine.
The system has also been used in several incidents involving civilian aviation. It was responsible for the destruction of civilian airliners during the Rhodesian Bush War and in Sudan. Non-state actors, including the Provisional IRA, the PKK, and various militant groups in the Middle East and Latin America, have operated the system. Naval versions, designated SA-N-5, were installed on various Warsaw Pact warships using pedestal mounts.
