Khrunichev State Research and Production Space Center is a Moscow-based producer of spacecraft and space-launch systems, including the Proton and Rokot rockets and is currently developing the Angara rocket family. The Proton launch vehicle launches from Baikonur and Rokot launches from Baikonur and Plesetsk. Angara will launch from Plesetsk and Vostochny.
Currently the largest rocket in the Angara family, Angara A5 utilizes five Universal Rocket Modules as the first stage, and is designed to phase out Proton.
The RD-191 is derived from the RD-180 duel-combustion chamber engine, which itself was derived from the four-chamber RD-170 originally used on the Energia launcher
The RD-0124 is used on the Soyuz-2.1b and Soyus-2.1v
