{{Short description|Air-launched rocket family}} '''RS-82''' and '''RS-132''' (Russian: Реактивный Снаряд, ''Reaktivny Snaryad''; rocket-powered projectile) were unguided rockets used by Soviet military during World War II.
==Development== Design work on RS-82 and RS-132 rockets began in the late 1920s, by the Gas Dynamics Laboratory (GDL)<ref name="W&WRRP">{{cite web |title=Russian Rocket Projectiles – WWII |url=https://weaponsandwarfare.com/2018/11/19/russian-rocket-projectiles-wwii/ |website=Weapons and Warfare |access-date=29 May 2022}}</ref> led by Georgy Langemak,<ref name = 'Siddiqi'>{{cite book |last1=Siddiqi |first1=Asif |title=Challenge to Apollo : the Soviet Union and the space race, 1945-1974 |date=2000 |publisher=National Aeronautics and Space Administration, NASA History Div. |page=17|location=Washington, D.C. |url=https://history.nasa.gov/SP-4408pt1.pdf |access-date=22 May 2022}}</ref> and including Nikolai Tikhomirov, Vladimir Artemiev, Boris Petropavlovsky, Yuriy Pobedonostsev, and others. The 82 mm (3.2 in) and 132 mm (5.2 in) diameters were chosen because the standard smokeless gunpowder charge used at the time was 24 mm (0.94 in) in diameter and seven of these charges fitted into an 82 mm cylinder. The first test-firing of a solid fuel rocket was carried out in March 1928, which flew for about 1,300 meters<ref name="RSB_GDL">{{cite web |last1=Zak |first1=Anatoly |title=Gas Dynamics Laboratory |url=http://www.russianspaceweb.com/gdl.html |website=Russian Space Web |access-date=29 May 2022}}</ref> and in 1932 in-air test firings of RS-82 missiles from an Tupolev I-4 aircraft armed with six launchers successfully took place.<ref name="R&P_Vol1">{{cite book |last1=Chertok |first1=Boris |title=Rockets and People |date=31 January 2005 |publisher=National Aeronautics and Space Administration |page=165 |edition=Volume 1 |url=https://www.nasa.gov/connect/ebooks/rockets_people_vol1_detail.html |access-date=29 May 2022}}</ref> In 1933 GDL became part of the Reactive Scientific Research Institute, where development of the rockets continued. In 1937, aerodynamically efficient '''RO-82''' rail launchers were designed for mounting these weapons on aircraft.
==Operational history== thumb|RS-82 RS-82 officially entered service in 1937 and RS-132 in 1938.<ref>{{cite web |title=Terrible fighting machine with a gentle maiden name |url=https://kpi.ua/en/1016-8 |website=National Technical University of Ukraine |access-date=30 May 2022}}</ref> The RS-82 missiles were carried by Polikarpov I-15, I-16 and I-153 fighter planes, the Polikarpov R-5 reconnaissance plane and the Ilyushin Il-2 close air support plane, while the heavier RS-132 missiles could be carried by bombers.<ref name="RSW_HRR" /> Many small ships of the Soviet Navy were also fitted with the RS-82 missile, including the MO-class small guard ship.<ref name="W&WRRP" />
The earliest known use by the Soviet Air Force of aircraft-launched unguided anti-aircraft rockets in combat against heavier-than-air aircraft took place in August 1939, during the Battle of Khalkhin Gol.<ref name="W&WRRP" /> A group of Polikarpov I-16 fighters under command of Captain N. Zvonarev were using RS-82 rockets against Japanese aircraft, shooting down 16 fighters and 3 bombers in total.<ref>{{cite book |last= Maslov |first= Mikhail|title= Polikarpov I-15, I-16 and I-153 Aces |publisher= Osprey Publishing |year= 2010 |isbn= 978-1-84603-981-2 |page=51}}</ref> In the same year, as part of the attempted annexation of Finland, in the Winter War, six RS-132 rockets were fired, from Tupolev SB bombers, against Finnish ground targets.<ref>{{Cite web |last=Aviation Museum |date=23 Feb 2021 |title=Unguided missile RS-82 (132) |url=https://ia803407.us.archive.org/1/items/mbrls-documents/Unguided%20missile%20RS-82%20%28132%29.%20-%20Russian%20aviation.pdf |archive-url= |archive-date=}}</ref>
Like most unguided rockets, RS suffered from poor accuracy. Early testing demonstrated that, when fired from 500 m (1,640 ft), a mere 1.1% of 186 fired RS-82 hit a single tank and 3.7% hit a column of tanks. RS-132 accuracy was even worse, with no hits scored in 134 firings during one test. Combat accuracy was even worse, since the rockets were typically fired from even greater distances. The RS-82 could destroy a tank with a direct hit and the larger RS-132 could knock out a tank with a near miss.<ref name="18RocketsWW2" /> Best results were usually attained when firing in salvos against large ground targets.
Almost every Soviet military aircraft of World War II was known to carry RS-82 and RS-132, often using field-made launchers. Some Ilyushin Il-2 were field-modified to carry up to 24 rockets although the added drag and the weight made this arrangement impractical. A total 12 million missiles of the RS-type were used by Soviet forces during World War II.<ref name="RSW_HRR" />
RS-derived '''M-8''' and '''M-13''' rockets were used by the famous Katyusha rocket artillery.<ref name="WW2Database_Ktatyusha">{{cite web |title=BM-13/8/31 Katyusha |url=https://ww2db.com/vehicle_spec.php?q=418 |website=World War II Database |access-date=29 May 2022}}</ref><ref name="RSW_HRR">{{cite web |last1=Zak |first1=Anatoly |title=History of the Rocket Research Institute, RNII |url=http://www.russianspaceweb.com/rnii.html |website=Russian Space Web |access-date=29 May 2022}}</ref><ref name="18RocketsWW2">{{cite book |last1=Alway |first1=Peter |title=Eighteen Rockets and Missiles of World War II |url=https://www.asp-rocketry.com/ecommerce/Eighteen-Rockets-and-Missiles-of-World-War-II.cfm?item_id=1336&parent=22 |access-date=29 May 2022}}</ref>
