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.
[1] It is produced in a variety of sub-types 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 feet 7 inches) long and weighs about 5 kg (11 lb), depending on warhead and fuze.
After 5 years, the Soviet ministry of defense finally provided official status and funding of the project in 1951,[3] originally as part of the air-to-air AS-5 weapon system for the MiG-19.
The improved S-5U is 1,090 mm (3.58 ft) long and weighs 6 kg (13 lb), making it longer and heavier than the previous S-5M, though it is compatible with older rocket pods.
It runs on composite propellant rather than a solid fuel motor and is spin-stabilized through four curved fins wrapped around the rocket nozzle to match its diameter when stored.
Effective range remains between 0.5–4 km (0.31–2.49 mi), but lethality is increased by a heavier 0.8 kg (1.8 lb) warhead.
It features a universal warhead that can penetrate 150 mm (5.9 in) of armor, explode into 500 2 g (0.071 oz) splinters, and has incendiary elements; combat efficiency is claimed to be comparable to the S-8 rocket.
In flight, the very slightly angled fins exert a stabilizing spin to the rocket, turning at approximately 750 rpm.
In addition the Soviet 40th Army made use of improvised launchers mounted on T-62 tanks, BTR-70 APCs and Ural-4320 trucks in a ground-to-ground role.
[9] According to the IDF, the rocket fired at Kibbutz Alumim in the Negev marked the first time Izz ad-Din al-Qassam Brigades have used this type of weapon.
[10] The S-5, along with S-8 and S-13 rockets, has been deployed from the backs of pick-up trucks (generally, technicals) during the 2011 Libyan civil war,[11] serving as a makeshift MLRS.
