The system was developed in scientific research institute NII-88 in 1953. Its rockets were propelled by a mix of kerosene and nitric acid. It has a range of 55km but was inaccurate.^[2]

Due to severe inaccuracy of the rocket, only a small quantity had been produced in USSR from 1957 to 1960. It was exported to South Yemen, which used them against North Yemen.^[3]
