Angara to move to Vostochny
After the cancellation of the Rus-M project in 2011, Russian space agency hatched plans to bring yet-to-be-tested Angara launch vehicle to Vostochny. The launch facility could be built at the same site that was originally eyed for the Rus-M's dual pad.

Origin of the plan
Provisional plans to launch Angara from Svobodny cosmodrome were made during the 1990s but never materialized. However following the cancellation of the Rus-M project in 2011, Roskosmos returned to the idea of bringing Angara (with similar payload capabilities to Rus-M) to what became Vostochny as a replacement. In turn, deploying Angara in Vostochny would make the Baiterek pad in Baikonur unnecessary. At the time, the construction of the Angara pad in Vostochny was considered as the second phase of development of the new launch center to be completed around 2018. However in January 2013, the Russian Vice-Prime Minister Dmitry Rogozin said that the light version of Angara would fly from Vostochny by 2015.
As of beginning of 2012, the unmanned version of Angara was reported to be able to carry up to 24 tons to the low Earth orbit from Vostochny, comparing to just 18 tons possible for delivery to the same orbit from its pad in Plesetsk. The same rocket could also place from 3.5 to 3.6 tons to a geostationary orbit from Vostochny, according to the head of Roskosmos.
The Amur OKR development plan
Under Roskosmos' tender announced in July 2012 and code-named Amur (after a great Siberian river), the Angara-5 rocket would be customized to fly from Vostochny, carrying a 20-ton new-generation PTK NP spacecraft. The first phase in the development of the Amur project would run until the end of May 2013, Roskosmos said.
In addition to its role in the manned space program, the Angara's launch complex in Vostochny would complement or even replace the original Angara facility in Plesetsk for launches into a geostationary orbit. Thanks to a much better geographical location of Vostochny for launches to the equatorial orbit, Angara-5 could carry a larger payload when compared to the launches of the same vehicle from Plesetsk. For missions to the geostationary orbit from Vostochny, Angara-5 would be equipped with the cryogenic KVTK upper stage when carrying its largest payloads and with the Block-DM stage for smaller satellites.
Given the extremely remote location of the Vostochny launch site in the Russian Far East and limitations of region's rail lines for non-standard cargo, Roskosmos hoped to break with the tradition of shipping rocket stages to the launch site by train. Instead, the agency considered a possibility of taking advantage of Russia's An-124-100 Ruslan transport aircraft for the delivery of Angara's rocket stages.
The development timeframe
In April 2013, the head of Roskosmos, Vladimir Popovkin said that the agency would request government funding for the construction of the Angara pad in Vostochny beginning in 2015 to avoid disbanding the workforce after the completion of the Soyuz pad in the Far East. The plan would require the government funding for the project to start a year earlier than originally planned.
At least some preliminary construction work at the site was promised to begin as early as 2013, and satellite imagery did show apparent clearing activities in the first half of the year. At the time, the first manned launch from the site was officially promised as early as 2018, but more likely it could take place around or after 2020.
On Oct. 23, 2013, Roskosmos announced a tender for the development of the launch complex 371SK32 for the Angara rocket in Vostochny. The agency allocated 813 million rubles for the work on the project code-named SK-Vostok-A (which stood for Launch Complex-Vostochny-Angara) until Nov. 25, 2014. This phase of the project was characterized as Opytno-Konstruktorskie Raboty, OKR, which can be translated as research and development work. In the Russian industrial terminology it usually refers to a second phase of development following the preliminary design.
As it was expected, Roskosmos essentially ordered to replicate in Vostochny the launch facility for the Angara-A5 that had been previously developed for Russia's northern launch site in Plesetsk. The agency's paperwork called for a two-pad launch facility to be developed into two phases. The first pad would be built to support three-stage Angara-A5 rockets with DM and KVTK upper stages. The pad would have to be modifiable for a three-stage Angara-A5 rocket carrying manned PTK NP spacecraft, the tender documentation said. The second pad could accommodate both manned and unmanned versions of the rocket.
At the time, Russian space officials still promised the first manned launch from Vostochny in 2018. However in February 2014, Roskosmos quoted its head Oleg Ostapenko as saying that the development of the Angara complex in Vostochny was subdivided in two phases: first -- the construction of the PU-1 launch pad (where PU stands for puskavaya ustanovka or "launch pad") for an unmanned version of the rocket and, only later -- the development of the PU-2 pad for the manned version of Angara. The announcement stressed that in order to complete the first (unmanned) pad in 2018, the construction would have to start in 2015. The statement essentially confirmed that the launch date of the first manned mission from Vostochny in 2018, which had often been quoted by the official media, had not actually been possible.
At the same time, Roskosmos announced that in December 2013, the survey work had been completed at the Angara site in Vostochny and the location of its facilities around the center had been determined. In addition, a cargo simulator of the Angara rocket had completed a dry run from the production factory at GKNPTs Khrunichev in Moscow to Vostochny, Roskosmos said on February 24, 2014. During the introduction ceremony of the new Director General of GKNPTs Khrunichev on August 7, 2014, Vice Prime-Minister Dmitry Rogozin said the work at the construction site of the Angara rocket would start at the beginning of autumn, the Interfax news agency reported.
During President Vladimir Putin's visit to Vostochny at the beginning of September 2014, Ostapenko publicly proposed to cut the money originally allocated for Angara's backup launch pads in Plesetsk and in Vostochny, in order to pay for the super-heavy launcher program. Still, at least a single pad for Angara was scheduled for the construction in Vostochny from 2016 to 2020.

The Russian space agency, Roskosmos, officially postponed the first launch of the Angara rocket from the nation's new launch site in Vostochny from 2018 to 2021. Previously quoted in various unofficial reports, the 2021 launch date is now appeared in the formal technical assignment to the industry for the development of the Angara launch facility in Vostochny. The delay also means that Russia's new-generation piloted spacecraft would not reach the launch pad until at least 2021 for its first unmanned test mission.
On November 13, 2014, Roskosmos issued a new tender for the development of the Amur complex (a.k.a. 371KK64), which includes the three-stage Angara-A5 rocket adapted for missions from Vostochny and its launch facilities at Russia's Far Eastern launch site. The final contract worth 12.6 billion rubles (approximately $267.2 million) would cover the development work until November 2023.
The documents of the tender specified Angara's key capabilities at its future launch pad and requirements for its future missions. According to the technical assignment in the tender, Angara-A5 would be able to deliver 24.5 tons to the low Earth orbit, when launched from Vostochny. The document said that separate technical assignments would be issued to adapt the rocket for various payloads including unmanned version of the next-generation manned spacecraft and for military satellites.
Specifically, for the Vostochny-based Angara, Roskosmos planned to start the Orion project in 2016, which would adapt Proton's current DM upper stage burning kerosene fuel for Angara-A5. In parallel, the Dvina-KVTK project would aim to build the hydrogen-powered KVTK upper stage for a more powerful version of the same rocket.
The requirements for the tender also confirmed that the first Angara pad in Vostochny, designated PU1, would be used to launch satellites and an unmanned version of the PTK NP spacecraft during its initial flight testing. A separate technical assignment would be issued for the second launch pad, the documents said without providing details.
Angara missions originating from Vostochny could enter orbit with an inclination 51.7 and 64.8 degrees toward the Equator. When entering the 51.7-degree orbit, the second stage of the rocket was expected to crash in the Sea of Okhotsk, 1,350 kilometers from the launch pad.
According to the schedule for the OKR Amur development project, Angara-A5 rockets for a series of test flights would have to be delivered during a period from 2021 to 2025, however the exact number of flight tests would be determined by the flight test program, the document said.
