Angara A5 (Russian: Ангара-А5), is a Russian expendable heavy lift launch vehicle which consists of one URM-1 core and four URM-1 boosters, a 3.6m URM-2 second stage, and an upper stage, either the Briz-M, Blok DM-03 or the KVTK.[2] Weighing 773 tonnes at lift-off, Angara A5 has a payload capacity of 24.5 tonnes to a 200 km (120 mi) x 60° orbit. Angara A5 is able to deliver 5.4 tonnes to GTO with Briz-M, or 7.5 tonnes to the same orbit with KVTK.[2]
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.[3]
The first Angara A5 test flight was launched on 23 December 2014. The second test flight was launched on 14 December 2020 from Plesetsk.[4]
