Structure Companies of the Khrunichev Space Center: Salyut Design Bureau Space Rocket Plant Space Hardware Operation Plant (ZERKT) Armatura Design Bureau Khrunichev Telecom Space Systems Research and Development Institute Medical Equipment and Consumer Goods Division Voronezh Mechanical Plant Polyot Production Corporation Isayev Chemical Engineering Design Bureau Ust-Katav Carriage Plant Named for S.M. Kirov (UKVZ) Production Khrunichev's main product is the Proton rocket, which has been launched more than 350 times since its creation in 1968. Latest version of the venerable rocket, which has been subject to several incremental upgrades, is Proton-M Enhanced; it has a lifting capability of 6,150 kg to geostationary transfer orbit. For use as Proton's upper stage, Khrunichev produces Briz-M, which first flew in 2000. Rockot, a converted ballistic missile, is offered for launching smaller payloads. For international marketing of Rockot launches, Khrunichev has created the joint-venture Eurockot GmbH. Another version of the Briz-M upper stage, Briz-KM, is used as Rockot's third stage. In 2009, the company manufactured a total of 25 launch vehicles, upper stage boosters and spacecraft, while in 2005 the figure was 11. In 2010, Khrunichev aims to raise the figure to 30. A record 15 rockets were launched by the company in 2009. In 2008, the company was responsible for lofting every third kilogram of the world's combined satellite payload. Revenue Khrunichev's revenue from commercial launches (not including launches for the Ministry of Defense) in 2009 was $584 million—growing considerably from the $198 million figure in 2004. Since 1994, Proton has earned $4.3 billion for the Russian space industry as a whole, and in 2011 this figure is expected to raise to $6 billion. In 2006–2009, investments in modernization and retooling amounted to RUB 2.6 billion. Angara rocket family Since 1995, Khrunichev has been developing the Angara rocket family. The main purpose of Angara is to ensure Russia's independent access to space, as
