The BM-25 Korshun (Kite) as its Russian (GRAU designation 2K5) name was a multiple rocket launcher designed in the Soviet Union. It was capable of launching 3R7 250 mm rockets from six launch tubes. The support vehicle is a YAZ-214.
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.
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.
