This vehicle assists in the alignment of the TELAR's radar systems, ensuring accurate target tracking and engagement. In addition to the TELARs, each regiment is also assigned a single radar collimation vehicle 9V914 (initially on the BAZ-5938 chassis but more often found on the ZiL-131 truck). A reload time of five minutes has been reported per TELAR. It can be used to track the target when the main tracking radar is jammed by ECM.Ī 9K33 battery comprises four 9A33B TELAR vehicles and two 9T217 transloader vehicles on BAZ-5939 chassis with reload missiles and a crane. There is also a tubular device fitted to and above the tracking radar this is a 9Sh33 electro-optical tracker. Furthermore, the two missiles can be guided on different frequencies to further complicate ECM. This twin antenna system permits the 'Land Roll' radar to control up to two missiles simultaneously against a single target. These are used for command uplink to the missile. The final antennas in the array are two small white rectangular ones, one on either side of the array mounted alongside the I band. Below that is a small circular antenna which emits an I band uplink capture beam to gather the missile shortly after launch. Mounted on either side of the tracking radar antenna is a small J band parabolic dish antenna to track the missile. The large pulsed J band (14.5 GHz) engagement antenna is mounted below it in the centre of the array and has a maximum tracking range of about 20 km. It consists of an elliptical rotating surveillance antenna mounted on top of the array, operates in H band (6 to 8 GHz) and has a 30 km acquisition range against most targets. The system is reported to be of the frequency-agile monopulse type.
It had improvements added to the launcher configuration, carrying six missiles in ribbed containers.

An improved system designated the SA-8B `Gecko' Mod 1, was first seen in Germany in 1980. It was derived from the naval `Pop Group' radar system but is smaller since it does not require the elaborate stabilisation system. The 1S51M3-2 radar system on the SA-8 TELAR received the NATO codename Land Roll. The six-wheeled transport vehicles BAZ-5937 are fully amphibious and air transportable. The SA-8 was the first mobile air defense missile system incorporating its own engagement radars on a single vehicle.Īll versions of the 9K33 feature all-in-one 9A33 transporter erector launcher and radar (TELAR) vehicles which can detect, track and engage aircraft independently or with the aid of regimental surveillance radars.
