Irtysh (Russian: Иртыш), also named Soyuz-5 (Russian: Союз-5), formerly codenamed Fenix in Russian and Sunkar (Kazakh: Сұңқар, lit. 'falcon') in Kazakh, is a planned Russian rocket that is being developed by RKTs Progress within the "Project Feniks" (Russian: Феникс, lit. 'phoenix'). Initially it will replace the capability of Zenit-2 and Proton Medium, and in the future will serve as the base of a super heavy-lift launch vehicle rocket (Yenisei) to match the Energia/Buran capabilities. As of August 2023, Irtysh is expected to launch from the Baikonur Baiterek, the ex Zenit-2 launch site, in a partnership with the government of Kazakhstan, with a planned debut in December 2025.
