Description
The Buk-M2E (NATO name SA-17 Grizzly) is a Russian made mobile medium-range surface-to-air missile (SAM) system designed to defend field troops and logistical installations against air threats. SA-17 Grizzly is an upgraded version of the proven Buk-M1 mobile air defense system and retains its main features. It defeats strategic and tactical aircraft, tactical ballistic missiles, cruise missiles, air-launched missiles, guided aerial bombs and helicopters, including hovering rotorcraft, in the presence of heavy electronic countermeasures and under intense enemy fire. Moreover, it can be used against sea-surface and ground targets. The Buk-M2E SAM system includes combat elements, such as atarget-acquisition radar, a battle management station, self-propelled firing vehicles, an illumination and guidance radar, loader-launcher vehicles, surface-to-air guided missiles, as well as maintenance and repair facilities. The combat elements can be mounted either on tracked or wheeled chassis. Wheeled trucks carry the maintenance facilities. The Buk-M2 can engage a wide variety of targets from aircraft to missiles flying at an altitude of between 10 and 24,000 m out a maximum range of 50 km in given conditions. The SA-17 Grizzly can engage simultaneous of up to 24 targets flying from any direction.

Missile
The SA-17 Gadfly uses the new 9M317 missile. The SA-17 Grizzly may also launch the 9M38 and 9M38M1 missiles. The missile was developed as a joint weapon for Russian Army and Navy air defence systems and has an extended engagement envelope when compared to the original Buk-M1 9M38M1 missile. The Buk M2E / SA-17 Grizzly 9A317 TELAR is equipped with the new NIIP 9S36 passive phased array engagement radar, which provides the capability to concurrently track and illuminate multiple targets for the four 9M317 Grizzly SAM rounds. The unified multi-functional 9M317 and 9M317E missiles are developed in compliance with advanced tendencies and classic traditions in the development of the world missile construction industry. It is a high-precision guided weapon integrated in the Army and Navy air defense systems and it is intended to defeat modern as well as future aerodynamic, ballistic, surface and radio-contrast surface threats. The 9M317 and 9M317E missiles designed by the DRPE JSC have passed complete series of ground and flight trials in various weapon systems. The missiles successfully hit following types of targets at the testing stage: analogues of tactical ballistic missiles, strategic cruise missiles, anti-ship missiles, cruise missiles, aircraft of the army, tactical and strategic aviation, helicopters, surface and ground radio contrast targets. The 9M317 missile is used in the Army in air defense missile system BUK Ml-2 and the 9M317E missile is used in the Navy in air defense missile system Shtil-1. The missiles can be integrated in the newly-developed systems providing them with multifunctional ability.
Mobility
The SA-17 Grizzly uses the same launcher vehicle chassis, and overall has a similar configuration to the SA-11 GADFLY. The Buk-M2 uses the GM-569 chassis designed and produced by JSC Metrowagonmash. The crew compartment provides protection from small arms fire as well as being sealed against NBC attack. The suspension either side consists of six dual roadwheels with the drive sprocket at the rear, idler at the front and four track-return rollers which support the inside of the double-pin track only. The SA-17 Grizzly 9A317E can run at a maximum speed of 65 km/h on road and 45 km/h on cross-country, with a maximum range of 500 km.
