Formally, the production of unguided S-13 missiles began during the Soviet times. However, according to Defense Express, the "upgrade" of the Mi-8-MSB-B helicopter was completed in April 2021, after a series of tests at the State Research Institute for Testing and Certification of Weapons and Military Equipment.
These tests have shown that Mi-8-MSB-B helicopters can use the entire range of unguided missiles S-13, such as high-explosive, penetrating, volume-detonating, etc.
Aiming data were also clarified, which showed that during horizontal flight and diving, the firing range of S-13 missiles from Mi-8-MSB-B is 4.5 km, in the pitch-up mode it’s up to 10 km.
