Tactical Use Of the SA – 8 in BMS

The system can’t launch missiles on the move, but can be prepared for engagement within four minutes of stopping. It takes 26 seconds from target detection to launch. The BAZ-5937 TELAR features a turret fitted with four elevating missile launch rails, each armed with a 9K33A round and two radars, including an identification friend and foe (IFF) system and missile capture and uplink antennas.

The 19-ton system features a vehicle section with a running length of 9 meters, width of 2.75 meters and a height of 4.2 meters. It's typical operating crew is five. The vehicle consists of a lightly-armored hull form atop a 6x6 wheeled chassis. The chassis supports cross-country travel while the hull is cleared for amphibious crossings which then played well into established Soviet ground warfare doctrine (forged largely by actions in World War 2 some decades earlier). The vehicle featured a D20K300 diesel-fueled engine of 300 horsepower output which provided driving ranges out to 500 kilometers and road speeds nearing 80 kmh. In water, the vehicle managed a pedestrian 8 kmh. The driving compartment lay at front in the usual way with the launcher component was sat over the rear of the vehicle, the radar element affixed over the frontal center mass. The six road wheels, three to a hull side, were large and well-spaced for good balance while the overall hull shape was quite shallow, presenting a smaller target along the horizon. The powered launcher component fitted two groups of three short-range missile launch tubes (for a total of six missiles) in a side-by-side arrangement - the launchers separated at center the radar component. A number of countries have modernised the 9K33 Osa to improve its detection capabilities and firing range following its entry into service. Its Belarusian upgrade is known as Osa-1T, while the Polish upgrade is called Osa-AKM-P1 Zadlo. Saman and Saman-M (Russian Саман – adobe) is a development of the Osa\Osa-M system into target drones, used for testing and training with air defense systems, including SAMs.
