The 2K11 Krug (Russian: 2К11 «Круг»; English: circle) is a Soviet and now Russian long range, medium-to-high altitude surface-to-air missile (SAM) system. "2K11" is its GRAU designation, while SA-4 "Ganef" is its NATO reporting name. The missiles are launched with the aid of four solid fuel rocket motors inside boosters attached to the outside of the massive missile. Once they have burned and the missile is aloft, it fires a liquid-fuelled ramjet sustainer engine. It reaches speeds of up to Mach 4 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). Image File history File links Sa-4. ... Image File history File links Sa-4. ... A Russian SA-4 TEL. Photo by GulfLINK.

The TEL vehicles are tracked (modified AT-Ts) and carry two missiles each on an elevating turntable for up to 360 degree rotation and 70 degree elevation. The two primary versions of the missile in service are the 9M8M1 (2K11M "Krug-M") and 9M8M2 (2K11M2/3 "Krug-M1"), both of which are believed to be known to the US DoD as SA-4B. The original 9M8M (SA-4A) was first introduced into service in 1965 and followed by the upgraded 9M8M1 (2K11A "Krug-A") in 1967 before the 9M8M1 in 1971 and the 9M8M2 in 1973. The 9M8M2 actually has a lower maximum engagement altitude and shorter range in exchange for better performance in engaging aircraft close to the battery. Each battery typically consists of two 9M8M1 missiles and four 9M8M2 missiles as well as the following radars: A Russian SA-4 TEL. Photo by GulfLINK. A Russian SA-8 TELAR.

The 9M8's enormous range makes it dangerous; however, the missiles are quite large and unlikely to hit small, maneuverable aircraft like fighter jets unless they are caught unaware.
