[1][3] The current proposal is led by JSC SRC Progress, with support by Khrunichev and Makeyev, additionally, RSC Energia would handle the launch site, and supply the Blok DM-03, while Roscosmos would finance the development through the Project Fenicks under the 2016–2025 Russian space master plan.
It would start with this commercial application with the prospect of also enabling a super heavy launcher with a 80 t (88 tons) payload capability to low Earth orbit.
As part of the 2016 arrangements, the Kazakh government would get ownership of one of the Proton launch pads, and participate in the operations of Proton-Medium and Proton-Light.
[3] As of August 2023 further delays in the construction of the launch site and in the development of the rocket pushed the date of the maiden flight to December 2025.
In July 2022, Dmitry Rogozin, then CEO of Roscosmos, admitted that construction would be postponed by six months to one year.
[8] In March 2023, it became public that the Baiterek Kazakh-Russian joint venture in charge of the site had seized the facility after filing a claim of about 2 billion rubles (30.3 million US-Dollar) to TsENKI, a Roscosmos subsidiary in charge of handling ground-based infrastructure, as Roscosmos had failed its obligation to conduct an environmental impact assessment of Site 45, causing additional delays.
Its base would still feature a 3.68 m (12.1 ft) aft section for compatibility with Zenit's pad and support infrastructure.
[5][13][10] The Irtysh first stage could be used as the boosters (and even core) of the super heavy rocket Yenisei capable of launching 73 t (80 tons) to low Earth orbit from Baikonur or Vostochny.
