Development

The S-13 rocket was developed in the 1970s to meet requirements for a penetrating weapon capable of cratering runways and penetrating hardened aircraft shelters, bunkers and pillboxes, to fill a gap between 80 mm and 240 mm rockets and fulfill a role similar to the 127 mm Zuni rocket. The S-13 is conventional in layout, with a solid rocket motor and folding tail fins that provide stability after launch.

The first trials were in 1973, but it was introduced only in 1983. S-13 rockets are shot from 5-tube launchers B-13L, that can be carried by most of Soviet and Russian attack and new fighter aircraft, like Sukhoi Su-17/20/22, Sukhoi Su-24, Sukhoi Su-25, Sukhoi Su-27, MiG-23BN, MiG-27, MiG-29. B-13L1 launcher is used by helicopters such as Mil Mi-24, Mil Mi-28, Kamov Ka-29TB, Kamov Ka-50 and Kamov Ka-52.
