2K11 Krug (NATO: SA-4 Ganef)

2K11 Krug (NATO: SA-4 Ganef)
anti-aircraft rocket system

A Soviet mobile long-range, medium- to high-altitude, surface-to-air missile system.

The development of the 2K11 Krug (circle) began in 1957 and production began in 1967. In 1971 upgraded versions Krug-M and in 1974 – Krug M1 went into production.

The system comprises a 2P24 tracked transporter-erector-launcher carrying two missiles on an elevating turntable for up to 360-degree rotation and 70-degree elevation; a 1S12 target detection station, a 1S32 missile guidance station and a 2T6 transporter-loader vehicle.

The missile is propelled by four externally mounted solid-fuel rocket boosters. Once they have burned and the missile is aloft, it fires a liquid-fuelled ramjet sustainer engine. It reaches speeds of up to 3,600 km/h and has an effective range of 50–55 km (31–34 miles) depending upon the version. It carries a 135 kg (300 lb) warhead. Possible engagement altitudes range from 100 m – 27 km (330–88,500 feet). The warhead weighs 135 kg. Missile guidance is via radio command with a terminal semi-active radar homing (SARH) phase (in M version).

The Krug system entered Soviet Army’s inventory in 1969. During 1979–1980 they were briefly deployed to Afghanistan, but were not used in combat. The Krug systems were also in inventories of other Warsaw Pact countries, including Poland (until 2011).
