Angara rocket
The Angara rocket is designed to reduce Russia's dependency on Kazakhstan (from whom they lease the Baikonur Cosmodrome) for heavy lift, as well as eliminate the need to purchase the Zenit from the Ukraine. The Angara will allow Russia to place objects in orbit while still maintaining the ability to launch payloads equivalent to the Proton rocket, the heavy lift workhorse for both the Soviet Union and then Russia.
The Angara family of rockets is designed to be modular, similar to the US EELV. It features multiple configurations with payloads to LEO ranging from 2,000 to 24,500 kilograms.
These rockets will be primarily launched at the Plesetsk Cosmodrome, a wholly Russian launch facility. Only the heavy Angara A5 will also be launched from Baikonur. An agreement with government of Kazakhstan about the construction of an Angara launch pad in Baikonur was signed in 2004. The first launch of an Angara (using the Angara A3 version) is expected to take place in the 2006-2007 timeframe at the Plesetsk Cosmodrome.
