The family of rockets Angara includes light, medium and heavy classes to carrier a payload of 3.8 to 35 tons. The lead developer and manufacturer of Booster is a Federal State Unitary Enterprise "State Research and Production Space Center Khrunichev." "I congratulate all those who were involved in this launch and establishment of the missile - designers, engineers, workers, and the military. Thank you for your selfless work"- added O.N.Ostapenko.

In the Angara A5, the four URM-1s used as boosters operate at full thrust for approximately 214 seconds, then separate. The URM-1 forming the vehicle's core is operated at full thrust for lift off, then throttled down to 30% to conserve propellant. The core is throttled back up after the boosters have separated and continues burning for another 110 seconds.
