Editing Energia (rocket) (section)

== Discontinuation and potential revival ==
Production of Energia rockets ended with the end of the Buran shuttle project in the late 1980s, and more certainly, with the [[Dissolution of the Soviet Union|fall of the Soviet Union]] in 1991. Since that time, there have been persistent{{cn|date=July 2022}} rumors of the renewal of production, but given the political realities, that is highly unlikely. 

While the Energia is no longer in production, the Zenit boosters were in use until 2017. The four strap-on [[Liquid Rocket Booster|liquid-fuel boosters]], which burned kerosene and liquid oxygen, were the basis of the Zenit rocket which used the same engines. The engine is the four combustion chamber [[RD-170]]. Its derivative, the [[RD-171]], was used on the [[Zenit rocket]]. A half-sized derivative of the engine, the two-chamber [[RD-180]], powers [[Lockheed Martin]]'s [[Atlas V]] rocket, while the single-chamber derivative, the [[RD-191]], has been used to launch the Korean [[Naro-1]] (as a reduced-thrust variant named the [[RD-151]]) and the Russian [[Angara (rocket)|Angara]] rocket. The RD-181, based on the RD-191, is used on the [[Antares (rocket)|Antares]] rocket.<ref>{{Cite web|url = http://spaceflightnow.com/news/n1407/09angara/#.U72yHvldV8E|title = First Angara rocket launched on suborbital test flight|date = July 9, 2014|access-date = July 9, 2014|website = Spaceflight Now}}</ref>

In August 2016, [[Roscosmos]] announced conceptual plans to develop a [[super heavy-lift launch vehicle]] from existing Energia components{{clarify|source seems to indicate that certain parts of the design might be reused; but not the actual components as full-up designed for their previous use|date=July 2022}} instead of pushing the less-powerful [[Angara A5]]V project.<ref>{{cite news |url=http://izvestia.ru/news/628028 |script-title=ru:"Роскосмос" создаст новую сверхтяжелую ракету |newspaper=[[Izvestia]] |date=August 22, 2016|language=ru }}</ref> This would allow Russia to launch missions towards establishing a [[Colonization of the Moon|permanent Moon base]] with simpler logistics, launching just one or two 80–160-ton super-heavy rockets instead of four 40-ton Angara A5Vs implying quick-sequence launches and multiple in-orbit rendezvous.<ref>{{cite web |last1=Zak |first1=Anatoly |title=Russia's New Rocket Project Might Resurrect a Soviet-Era Colossus |url=https://www.popularmechanics.com/space/rockets/a22515248/russia-super-rocket-energia/ |website=Popular Mechanics |date=24 July 2018 |publisher=Hearst Digital Media |access-date=24 October 2019}}</ref>
Tests of [[RD-170#RD-171MV|RD-171MV]] engine, an updated version of the engine used in Energia, were completed in September 2021 and may potentially be used in the successor [[Irtysh (rocket)|Soyuz-5]] rocket.<ref>{{cite web |last1=Berger |first1=Eric |title=Rocket Report: Next Falcon Heavy launch date set, Soyuz 5 engines clear tests |url=https://arstechnica.com/science/2021/09/rocket-report-next-falcon-heavy-launch-date-set-soyuz-5-engines-clear-tests/ |website=Ars Technica |date=9 October 2021}}</ref>
