Earlier reports indicated that the Federation would be launched from the Vostochny cosmodrome in Russia's Far East.
"There is a decision that the first launch of the Federation manned spacecraft will be carried out on a Soyuz-5 rocket from the Baikonur cosmodrome," Roscosmos head Igor Komarov said said on the sidelines of the St. Petersburg International Economic Forum (SPIEF).
Russia's Energia space corporation said in March that the Federation, which is 80 percent built of composite materials, will be manufactured by 2021.
Moreover, the new Vostochny Cosmodrome in Russia's Far East will be used for civilian and military space launches, the head of Roscosmos State Space Corporation Igor Komarov said Friday.
"We understand that there are specific requirements on our part and on the part of the Russian Defense Ministry in terms of ensuring the safety of the launches and the need for them. The Vostochny spaceport will be shared with the Defense Ministry," Komarov said on the sidelines of the St. Petersburg International Economic Forum (SPIEF).
Plans for Vostochny earlier envisioned only the civilian use.
SPIEF, a major global platform for communication between business representatives and discussion of crucial economic issues, kicked off in Russia’s St. Petersburg on Thursday and will continue through Saturday. Sputnik News Agency is the official media partner of the forum.
