The '''2S7 Pion''' ("[[peony]]") or '''2S7M Malka''' is a [[Soviet Union|Soviet]] [[self-propelled artillery|self-propelled]] 203&nbsp;mm [[cannon]]. "2S7" is its [[GRAU]] designation. More than 250 units were built; some sources say 500,<ref name=tankenc/> others up to 1,000.<ref name=janesaa/> They were distributed around the former [[Soviet states]] during  the [[dissolution of the Soviet Union]] in 1991.

==Description==
The 2S7 Pion was identified for the first time in 1975 in the [[Soviet Army]] and was called '''M-1975''' by [[NATO]] (the [[2S4 Tyulpan]] also received the M-1975 designation), whereas its official designation is '''SO-203 (2S7)'''. It used a new-design chassis, partly based on T-72 and T-80 design,<ref name=tankenc>{{Cite web |title=Soviet 2s7 Pion SPG (1975) |url=https://www.tanks-encyclopedia.com/coldwar/ussr/2s7-pion.php |access-date=19 April 2022 |website=www.tanks-encyclopedia.com |archive-date=20 May 2022 |archive-url=https://web.archive.org/web/20220520001420/https://www.tanks-encyclopedia.com/coldwar/ussr/2s7-pion.php |url-status=live }}</ref> carrying an externally mounted 2A44 203&nbsp;mm gun on the hull rear.<ref>{{cite book |title=Soviet/Russian Armor and Artillery Design Practices: 1945-1995 |date=1995 |publisher=[[Marine Corps Intelligence Activity]] |location=Quantico, VA |url=https://ntrl.ntis.gov/NTRL/dashboard/searchResults/titleDetail/PB96134846.xhtml |access-date=16 March 2024 |pages=V-14–V-15}}</ref> The vehicle is self-entrenching and has an overpressure [[CBRN defense]] system.<ref name="fas203">{{cite news |title=2S7 203-mm Self-Propelled Gun |url=https://man.fas.org/dod-101/sys/land/row/2s7.htm |publisher=FAS Military Analysis Network |date=16 October 1999 |access-date=29 May 2022 |archive-date=25 December 2021 |archive-url=https://web.archive.org/web/20211225092411/https://man.fas.org/dod-101/sys/land/row/2s7.htm |url-status=live }}</ref> It was reported that the {{convert|12|m|abbr=on}} gun weighs {{convert|14.6|t|abbr=on}} and has a service life of 450 rounds.<ref name=mcia1995/>

The Malka modernization process in the late 2010s involved substituting several of the Ukrainian-produced components, such as the gearbox and engine, with new components manufactured in Russia at the [[Uraltransmash]] plant in [[Yekaterinburg]].<ref name="raru">{{cite news |title=Russia Army Receives Upgraded 2S7M Malka Self-propelled Heavy Howitzer |url=https://militaryleak.com/2021/12/13/russia-army-receives-upgraded-2s7m-malkas-self-propelled-heavy-howitzer/ |date=13 December 2021 |publisher=Military Leak |access-date=29 May 2022 |archive-date=27 January 2022 |archive-url=https://web.archive.org/web/20220127234817/https://militaryleak.com/2021/12/13/russia-army-receives-upgraded-2s7m-malkas-self-propelled-heavy-howitzer/ |url-status=live }}</ref>

The 2S7 uses a tracked chassis that was designed specifically for this artillery system. It uses a number of automotive components from the [[T-72]] and [[T-80]] main battle tanks. It is powered by a [[V-46-I]] turbocharged liquid-cooled [[V12 engine|V12]] [[diesel engine]],<ref name=tankenc/> developing {{convert|560|kW|abbr=on}} (or {{convert|630|kW|abbr=on}}<ref name=am2s7/>). It is also fitted with an auxiliary power unit, developing {{convert|18|kW|abbr=on}} and powering all systems when the main engine is shut down.<ref name="auto">{{cite web|url=http://www.military-today.com/artillery/2s7_pion.htm|publisher=Military Today|title=2S7 Pion|access-date=10 January 2010|archive-url=https://web.archive.org/web/20090709114426/http://www.military-today.com/artillery/2s7_pion.htm|archive-date=9 July 2009|url-status=usurped}}</ref>

The 2S7 carries a crew of fourteen and eight rounds of ammunition; seven crewmembers and four rounds are carried by the Pion, with the remaining crew and rounds in an auxiliary vehicle.<ref name=auto/>

It takes the crew about six minutes to set up and five minutes to dismantle. The vehicle carries four 203&nbsp;mm projectiles for immediate use. The gun is capable of firing nuclear ammunition.<ref name="wsn203">{{cite news |title=203mm shells for 2A44 howitzer |url=https://weaponsystems.net/system/145-203mm+shells+for+2A44+howitzer |access-date=29 May 2022 |publisher=WEAPONSYSTEMS.NET |archive-date=29 May 2022 |archive-url=https://web.archive.org/web/20220529202348/https://weaponsystems.net/system/145-203mm+shells+for+2A44+howitzer |url-status=live }}</ref> The gun has a range of {{convert|37.5|km|abbr=on}}, but this can be extended to {{convert|47.5|km|abbr=on}} by using a [[rocket-assisted projectile]].<ref name=auto/> One interesting feature of the Pion is the firing alarm. Because the blast of the weapon firing is so powerful, it can physically incapacitate an unprepared soldier or crew member near it from the concussive force, the Pion is therefore equipped with an audible firing alarm that emits a series of short warning tones for approximately five seconds prior to the round being fired.<ref name=raru/>

==Operational and combat history==
* The 2S7 was first used in combat by the Soviet Union in [[Soviet–Afghan War]] (1979–1989){{citation needed|date=May 2022}}
* Russian forces used it in the [[First Chechen War|First]] and [[Second Chechen War]]s (First war: 1994–1996, Second war: 1999–2009){{citation needed|date=May 2022}}
* The [[Georgian Army]] used 2S7s in the [[Russo-Georgian War]] in 2008 (7–16 August 2008), five were visually confirmed as lost during the war: four destroyed and one captured by the Russian forces.<ref>{{cite web |title=Russia's Wars: Listing Equipment Losses During The 2008 Russo-Georgian War |url=https://www.oryxspioenkop.com/2022/10/russias-wars-listing-equipment-losses.html |website=Oryx |access-date=20 August 2023 |archive-date=4 October 2022 |archive-url=https://web.archive.org/web/20221004135902/https://www.oryxspioenkop.com/2022/10/russias-wars-listing-equipment-losses.html |url-status=live }}</ref>
* 2S7s were brought back into service by the Ukrainian army during the [[War in Donbas (2014–2022)|war in Donbas]] in late 2014,<ref name=ukr99/> and were used in combat just outside the 'buffer' zone stipulated by the [[Minsk Protocol]], as they had long enough range to still provide artillery support.<ref name=wfukr>{{cite web|title=2S7 Pion|url=http://warforukraine.com/weapons/artillery/ukrainian-artillery/41-2s7pion.html|website=War for Ukraine|access-date=2 April 2016|archive-url=https://web.archive.org/web/20160414072152/http://warforukraine.com/weapons/artillery/ukrainian-artillery/41-2s7pion.html|archive-date=14 April 2016|url-status=live}}</ref>
