The Angara rocket family is a family of light, medium and heavy-lift launchers being developed by the Khrunichev State Research and Production Space Center . The different versions of Angara provide payload capabilities of 2,000 to 24,500 Kilograms into Low Earth Orbit.They are re intended to replace several existing launch vehicles.
After the dissolution of the Soviet Union, many formerly Soviet launch vehicles were built in or required components from companies now located in Ukraine and the Soviet Union's main spaceport, Baikonur Cosmodrome, was located in Kazakhstan. . In 1992 it was decided to develop a new Russian launch vehicle, named Angara, to replace the rockets now built outside of the country, and ensure Russian access to space without Baikonur.
Angara uses a modular approach to create a number of different launch vehicle versions with different payload capabilities. The concept is centered around the Universal Rocket Module that builds the core stage of the launcher and can also function as a strap-on booster. Angara has been designed to use one , three , five and seven cores to create a range of launch vehicle options. Angara can fly as a two or three-stage launch vehicle.Each core is powered by RD-191 engine . The RD-191 is a single-chamber engine and is capable of throttling down to at least 30%, allowing core stage to conserve propellant until booster separation.
The second stage of the Angara, called URM-2 using RD-0124A engine . It has a diameter of 3.6 meters for the Angara A5and 2.66 meter for Angara 1.2 .
Angara can use operational Briz-M that using hypergolic propellants and a new generation of cryogenic upper stages using liquid oxygen and liquid hydrogen propellants.
Currently Angara rockets are launched from the Plesetsk Cosmodrome..It is planned to be launched from the Vostochny Cosmodrome under construction .

The South Korean launch vehicle Naro-1 used a first stage derived from Angara's URM-1 . It is
fitted with a lower-thrust version of the RD-191 engine called RD-151 . The vehicle made its first flight on August 25, 2009. The flight was not successful,
