Buk missile system

The Buk (Russian: "Бук"; "beech" (tree), /bʊk/) is a family of self-propelled, medium-range surface-to-air missile systems developed by the Soviet Union and its successor state, the Russian Federation, and designed to counter cruise missiles, smart bombs, fixed- and rotary-wing aircraft, and unmanned aerial vehicles. In the Russian A2AD network, Buk is located between the S-200/300/400 systems above and the point defense Tor and Pantsir type systems below.

A standard Buk battalion consists of a command vehicle, target acquisition radar (TAR) vehicle, six transporter erector launcher and radar (TELAR) vehicles and three transporter erector launcher (TEL) vehicles. A Buk missile battery consists of two TELAR (four missiles apiece) and one TEL vehicle, with six missiles for a full complement of 14 missiles.

The Buk missile system is the successor to the NIIP/Vympel 2K12 Kub (NATO reporting name SA-6 "Gainful"). The first version of Buk adopted into service carried the GRAU designation 9K37 Buk and was identified in the west with the NATO reporting name "Gadfly" as well as the US Department of Defense (DoD) designation SA-11.

With the integration of a new missile the Buk-M1-2 and Buk-M2 systems also received a new NATO reporting name Grizzly and a new DoD designation SA-17. Since 2013, the latest incarnation "Buk-M3" is currently in production and active service with a new DoD designation SA-27.

A naval version of the system, designed by MNIIRE Altair (currently part of GSKB Almaz-Antey) for the Russian Navy, received the GRAU designation 3S90M and will be identified with the NATO reporting name Gollum and a DoD designation SA-N-7C, according to Jane's Missiles & Rockets. The naval system was scheduled for delivery in 2014.

A Buk missile was used to shoot down Malaysia Airlines Flight 17.
