The '''SCE-200''' is an Indian, under-development, [[liquid-fuel rocket|liquid-fuel]] [[rocket engine]], burning [[liquid oxygen]] (LOX) and [[RP-1]] kerosene in an oxidizer-rich [[staged combustion cycle]].{{citation needed|date=April 2019}} This engine is expected to power [[Indian Space Research Organization]]'s upcoming [[Unified Launch Vehicle]] (ULV) and [[RLV-TD|Reusable Launch Vehicle (RLV)]].<ref name=isro-ar2013 /> It is being developed by the [[Liquid Propulsion Systems Centre]], a subsidiary of ISRO. But before that it will be tested on a [[Geosynchronous Satellite Launch Vehicle Mk III|GSLV Mk III]] by replacing the L110 stage powered by the [[Vikas engine]] with an SC-200 stage powered by SCE-200 engine and a 200 tonne propellant load.<ref>{{Cite web|url=http://www.isro.gov.in/sites/default/files/article-files/right-to-information/annual_report-15-16.pdf|title=Government of India, Department of Space, Annual Report 2015 - 2016|date=26 May 2016|archive-url=https://web.archive.org/web/20161213050333/http://www.isro.gov.in/sites/default/files/article-files/right-to-information/annual_report-15-16.pdf|archive-date=13 December 2016|url-status=dead}}</ref><ref>{{Cite news|url=https://the-ken.com/isro-heaviest-rocket/|title=ISRO's heaviest rocket is ready but is it enough for the load that lies ahead?|last=Raj|first=Gopal|date=5 June 2017|work=The Ken|access-date=5 June 2017}}</ref><ref>{{Cite news|url=http://www.newindianexpress.com/states/tamil-nadu/2017/jun/07/post-successful-launch-of-indias-heaviest-rocket-isro-sets-its-eyes-on-10-tonne-class-payload-laun-1613673.html|title=Post successful launch of India's heaviest rocket, ISRO sets its eyes on 10-tonne class payload launcher|work=NewIndianExpress|access-date=7 June 2017}}</ref><ref>{{Cite web|url=https://www.isro.gov.in/annual-report-2016-2017-english|title=Annual Report 2016 -2017 (English) - ISRO|website=www.isro.gov.in|language=en|access-date=2018-02-13}}</ref>

On June 2, 2005, [[India]] and [[Ukraine]] signed the ''Framework Agreement between the Government of Ukraine and the Government of the Republic of India on Cooperation in the Peaceful Uses of Outer Space'', which would enter in force on February 15, 2006.<ref name=mfa-ukraineindialegalacts /> As per unconfirmed information obtained by [[WikiLeaks]] this contract involved the transfer of blueprints for a rocket engine by the [[Yuzhnoye Design Office]].<ref name=wl-07kyiv2245 /><ref name=wl-07kyiv2490 /><ref name=wl-08kyiv962 />

According to official press release on March 26, 2013, by Ukrainian Ministry of Economic Development and Trade, development of a rocket engine for Indian launch vehicles initiated in 2006 under a joint Indian-Ukrainian project named “Jasmine”<ref>{{Cite web|url=http://www.kmu.gov.ua/control/uk/publish/article?art_id=246185883|title=Урядовий портал :: Україна розробляє ракетний двигун для індійської ракети-носія|website=www.kmu.gov.ua|access-date=2016-03-15}}</ref><ref>{{Cite web|url=http://www.kmu.gov.ua/control/uk/publish/article?art_id=246186471|title=Урядовий портал :: Ukraine designs rocket for Indian launch vehicle|website=www.kmu.gov.ua|access-date=2016-03-15}}</ref><ref name=":0">{{Cite web|url=http://www.russianspaceweb.com/rd810.html|title=Ukraine to test components of a powerful Indian rocket engine|website=www.russianspaceweb.com|access-date=2018-01-11}}</ref><ref>{{Cite news|url=http://old.kmu.gov.ua/kmu/control/uk/publish/article?art_id=246185883&cat_id=248439752|title=Україна розробляє ракетний двигун для індійської ракети-носія|date=26 Mar 2013|work=kmu.gov.ua|access-date=11 Jan 2018|archive-url=https://web.archive.org/web/20180111154536/http://old.kmu.gov.ua/kmu/control/uk/publish/article?art_id=246185883&cat_id=248439752|archive-date=11 January 2018}}</ref><ref>{{Cite news|url=http://old.kmu.gov.ua/kmu/control/en/publish/article?art_id=246186471|title=Ukraine designs rocket for Indian launch vehicle|date=26 Mar 2013|work=old.kmu.gov.ua|access-date=11 Jan 2018|archive-url=https://web.archive.org/web/20180111155207/http://old.kmu.gov.ua/kmu/control/en/publish/article?art_id=246186471|archive-date=11 January 2018}}</ref>

During May and June 2015, ISRO and [[Russian Federal Space Agency|Roscosmos]] signed a wide-ranging [[Memorandum of Understanding]] for cooperation in space.<ref name="thehindu-a7536263" /> [[A. S. Kiran Kumar]], Chairman of the ISRO, stated that one of the first benefits would be the availability of Russian test stand for initial testing of the SCE-200, while the [[ISRO Propulsion Complex|Mahendragiri]] semi-cryogenic test stand being built. The engine is a part of the {{INRConvert|1800|c}} semi-cryogenic launch vehicle program, which would be capable of placing {{convert|6000|-|10000|kg|lb}} in [[Geostationary transfer orbit|GTO]].<ref name="thehindu-a7536263" /><ref name="vssc-hllv" />

In 2017, Ukrainian firm Yuzhmash was contracted by ISRO to conduct tests on critical components of SCE-200.
