The S-5 (first designated ARS-57) is a rocket weapon developed by the Soviet Air Force and used by military aircraft against ground area targets. It is in service with the Russian Air Force and various export customers.
It is produced in a variety of subtypes with different warheads, including HEAT anti-armour (S-5K), high-explosive fragmentation (S-5M/MO), smoke, and incendiary rounds. Each rocket is about 1.4 meters (4 ft 6 in) long and weighs about 5 kg (11 lb), depending on warhead and fuze. Range is 3 to 4 kilometres (1.9 to 2.6 miles).
The S-5 is carried in rocket pods, with 4 - 32 rockets. The first were ORO-57 launchers, made in variants with capacity of 4, 8 and 16 rockets. Most typical became ORO-57K for 8 rockets, used especially with MiG-19. Then, from early 1960s, typical launcher became UB-16-57, with 16 rockets, developed in several variants, for helicopters and planes. UB stands for "universal block", for it could be carried on typical bomb hardpoints, "57" is referring to the actual diameter of the launch tube (the diameter of the rocket plus 2 mm). First variant and UB-16-57U had conical forward part, next variant UB-16-57D had blunt forward part. From 1968, a variant UB-16-57UMP was produced, with conical forward part and sticking out five inner tubes. In the 1970s there was developed an ultimate launcher UB-32 with 32 rockets, carried by heavier aircraft. In Poland, Mars-2 launcher was developed for 16 rockets.
S-5 rockets were used extensively by Sukhoi Su-25 and Mil Mi-24 aircraft in Afghanistan in the 1980s, where their effectiveness was considered poor. Pilots described the rockets fanning out after launch "like a tulip", and that the warhead was only good for "tickling the dookhi's (mujahedeen) heels". The Russian forces have shifted to higher-calibre weapons like the S-8 rocket instead.
