"About 400 OSA systems have been adopted by different countries," Alexander Konopolov, chief designer at the Izhevsk Electromechanical Plant Kupol, said at the presentation ceremony. Various aspects of the antiaircraft missile system have been modernized - crew protection has been enhanced, combat control efficiency has been improved, the payload has been replaced, and microwave devices and units have been changed.
"Among the innovations introduced through the system's modification are a day-night electro-optical finder and 'traps', special devices to protect the vehicle from HARM missiles," Konopolov said. OSA-AKM has also been equipped with a radar locating system.
Konopolov specified that modernizing the payload of the 9M33M3 missile increased its target destruction effectiveness by 10-20 %.
OSA-AKM is capable of spotting targets at a distance of up to 45 kilometers and hitting targets 25 to 5,000 meters high from 1,500 to 10,000 meters. It takes no longer than four minutes to put the system into combat mode. The vehicle can reach a speed of 60 kilometers per hour on land and eight kilometers per hour on water.
