'''Site 35''' at the Plesetsk Cosmodrome is a launch complex used by [[Russia]]'s [[Angara (rocket family)|Angara]] rocket. The complex has a single [[launch pad]], Site 35/1, which was first used for the [[Angara-1.2pp|maiden flight]] of the Angara in July 2014.

Site 35 was originally intended to support the [[Zenit (rocket family)|Zenit]] rocket, which the [[Soviet Union]] saw as a replacement for the [[R-7 (rocket family)|R-7 series]]. The construction of a Zenit launch complex at Plesetsk was authorised in 1976; however, development did not begin until the completion of [[Baikonur Cosmodrome Site 45|Site 45]] at the [[Baikonur Cosmodrome]], which was also constructed for Zenit. Construction at Site 35 began in the mid-1980s, but the programme was abandoned following the [[dissolution of the Soviet Union]].<ref name="NSF2">{{cite web |last=Graham |first=William |date=9 July 2014 |title=Angara rocket launches on maiden flight |url=http://www.nasaspaceflight.com/2014/07/russias-angara-rocket-maiden-flight/ |accessdate=20 December 2014 |publisher=NASASpaceflight.com}}</ref>

Following the cancellation of Zenit launches from Plesetsk, Russia had originally planned to use parts constructed for Site 35 to repair one of the Zenit pads at Baikonur that had been heavily damaged when a rocket lost thrust and fell back into the flame trench seconds after launch. Instead, the parts were eventually used on [[Sea Launch]]'s ''[[Odyssey (launch platform)|Odyssey]]'' launch platform.<ref name="rsw2">{{cite web |last=Zak |first=Anatoly |title=Angara launch facility in Plesetsk |url=http://www.russianspaceweb.com/plesetsk_angara.html |accessdate=20 December 2014 |work=RussianSpaceWeb}}</ref>

When Russia began development of the Angara rocket, launch pads at both Plesetsk and Baikonur were planned. Several existing sites at Plesetsk were considered, including [[Plesetsk Cosmodrome Site 41|Site 41/1]], [[Plesetsk Cosmodrome Site 16|Site 16/2]], and [[Plesetsk Cosmodrome Site 32|Site 32]]; Site 35/1 was determined to be the most suitable. Construction began in 2004 but was not completed until April 2014.<ref name="rsw2"/>

The Angara made its maiden flight—in the one-off [[Angara-1.2pp]] configuration—from Site 35/1 on 9 July 2014, flying a successful suborbital test mission.<ref name="NSF2"/> The first orbital launch from the site was the inaugural launch of the Angara A5 on 23 December 2014, which carried a mass simulator.<ref>{{cite web |last=Clark |first=Stephen |date=19 November 2014 |title=Russia's new heavy-lifter rolled to launch pad |url=http://spaceflightnow.com/2014/11/19/russias-new-heavy-lifter-rolled-to-launch-pad/ |accessdate=20 December 2014 |publisher=Spaceflight Now}}</ref> A second orbital test flight of the Angara A5 took place almost six years later, on 14 December 2020.<ref>{{cite web |date=14 December 2020 |title=Second test launch of Angara-A5 heavy rocket carried out in Plesetsk |url=https://tass.com/science/1234599 |accessdate=14 December 2014 |publisher=TASS}}</ref>
