On January 20, 2016, Roskosmos officials admitted that budget cuts at the end of 2015 had required to drop plans to build one of the two launch pads for Angara rockets in Vostochny. Previously, the Russian space officials claimed that a dual launch complex for the Angara was absolutely necessary to support the four-launch scenario of the lunar expeditions relying on the Angara-5V rocket.
The beginning of the construction of the remaining single pad was now delayed from 2016 to 2017. The facility could still be designed to accomodate multiple members of the Angara family, including Angara-5 and Angara-5V and, eventually, their man-rated versions.
To save money, the Amur project, which aimed to bring the Angara family to Vostochny, was subdivided into two phases. Only the first phase, which funded the deployment of the Angara-5/KVTK and Angara-5P rockets at the site, would reach flight tests in 2021, during the Federal Space Program extending from 2016 to 2025. The completion of the second phase, which would see the first unmanned launch of the Angara-5V rocket from Vostochny, was now postponed from 2024 to beyond 2025.
So there will be an Angara launch pad at Vostochny by 2021. There would have been two if not for budget cuts. But
even one is good enough. They already have one at Plesetsk. I don't see the urgency for three Angara launch pads.
