B-8 rocket pod / S-8 rockets

S-8_KOM_80_mm_rocket

The S-8 can be considered an enlarged version of the S-5. The warhead and fuze are located at the front and the short burning rocket motor makes up most of the body. Each rocket has six folding fins that are retracted upon launch an provide stability in flight. The length and weight differ depending on warhead. S-8 rockets are unguided free flight rockets and do not feature any guidance. Targeting is achieved by pointing the launch aircraft in the direction of the target.

The S-8 is much more effecive than the earlier S-5 rockets due to much higher accuracy and more powerful warheads. A wide variety of warheads is available which includes HEAT-Frag, anti-runway, thermobaric, illumination and others. Depending on the warhead the maximum range is 2 to 4.5 km. A 20 round rocket pod can be ripple fired in only a few seconds. A laser guidance kit for S-8 rockets has been developed, but is not in use yet.

The S-8 rockets are used on attack helicopters and ground attack fighters. On helicopters it is most commonly used on the Mi-24 Hind attack helicopter, but can also be found on armed versions of the Mi-8 Hip and the latest Mi-28 and Ka-50 attack helicopters. The Su-25 Frogfoot is the main fixed wing aircraft on which the S-8 is used, but it is also used on the Su-17 Fitter, MiG-29 Fulcrum, MiG-27 Flogger, Su-27 Flanker and Su-24 Fencer.

The S-8 was in widespread use with Soviet forces at the later stages of the Cold War and replaced most S-5 missiles in use. The S-8 remains in widespread use and has been exported to various Warsaw Pact members and Soviet allies. The S-8 remains in widespread use today.

The B-8M1 rocket pod is the 20 round version for use on fixed wing aircraft. Compared to the helicopter version the B-8M1 is more streamlined resulting in much reduced drag. The rockets are arranged in two circles with an inner circle of 7 round and an outer circle of 13 rounds.

The B-8V20A rocket pod is the standard 20 round version for helicopter use. Unlike the B-8M1 it is not streamlined and it has the advantage of being lighter. The rockets are arranged in two circles with an inner circle of 7 round and an outer circle of 13 rounds. The B-8V7 is the latest rocket pod for the S-8. It is much smaller and lighter since it carries only 7 rounds. Unlike the other S-8 rocket pods it can be used on both helicopters and fixed wing aircraft.

The S-8 rockets come in a large number of versions that differ in warhead type and effective range.
S-8KO: HEAT-Frag warhead for use against infantry, vehicles and normal buildings. Most common S-8 version.
S-8KOM: Improved version of the S-8KO.
