Variants
Angara 1.2
The smallest Angara is the Angara 1.2, which consists of one URM-1 core and a modified Block I second stage. It has a lift-off mass of 171 tonnes and can deliver 3.8 tonnes of payload to a x 60° orbit. The successful maiden launch of Angara 1.2 took place 29 April 2022.
Angara 1.2pp
A modified Angara 1.2, called Angara 1.2PP (''Angara-1.2 pervyy polyot'', meaning ''Angara-1.2 first flight''), made Angara's inaugural suborbital flight on 9 July 2014. This flight lasted 22 minutes and carried a mass simulator weighing . Angara 1.2PP weighed and consisted of a URM-1 core stage and a partially fueled -diameter URM-2, allowing each of the major components of Angara A5 to be flight tested before that version's first orbital launch, conducted on 23 December 2014.
Angara A5
The second Angara developed was the Angara A5 heavy lift launch vehicle

or the KVTK. Weighing 773 tonnes at lift-off, Angara A5 has a payload capacity of 24.5 tonnes to a 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.
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.
The first Angara A5 test flight was launched on 23 December 2014. The second test flight was launched on 14 December 2020 from Plesetsk. A third test flight was launched on 27 December 2021, also from Plesetsk. However, the test of Persei upper stage failed and the payload did not make it from LEO to GEO.
Proposed versions
Angara 1.1
Initial plans called for an even smaller Angara 1.1 using a Briz-KM
The Briz-K, Briz-KM and Briz-M (russian: Бриз-К, КM and M meaning ''Breeze-K, KM and M'') are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on t ...
as a second stage, with a payload capacity of 2 tonnes. This version was cancelled as it fell into the same payload class as the Soyuz 2.1v, which made its debut flight in 2013.
Angara A3
The Angara A3 would consist of one URM-1 core, two URM-1 boosters, the 3.6m URM-2, and an optional Briz-M or hydrogen powered upper stage for high energy orbits. The hydrogen powered stage for this vehicle, called RCAF would be smaller than the Angara A5's KVTK. This vehicle has no current plans for use (14.6 tonnes to 200 km x 60°, 2.4 tonnes to GTO with Briz-M or 3.6 tonnes with a hydrogen upper stage), but could be developed as a replacement for Zenit.
Angara A5P

has proposed an Angara A5 capable of launching a new crewed spacecraft weighing up to 18 tonnes: the Angara 5P. This version would have 4 URM-1s as boosters surrounding a sustainer core URM-1 but lack a second stage, relying on the spacecraft to complete orbital insertion from a slightly suborbital trajectory, much like the Buran or Space Shuttle

. This has the advantage of allowing all engines to be lit and checked out while on the ground, eliminating the possibility of an engine failing to start after staging. The RD-191 engines may also be operated at reduced thrust to improve safety.
Angara A5V
Khrunichev has proposed an upgraded Angara A5 variant with a new big hydrogen-based upper stage (URM-2V) as replacement for URM-2 and upgraded engine thrust on the URM-1 stages. The thrust up the URM-1 boosters would be 10% higher during the first 40 seconds to allow good thrust/weight ratio even with the URM-2 replaced with the heavier URM-2V. Cross-feed and even more powerful RD-195 engines for the URM-1 are also considered. The capacity of A5V is supposed to be around 35-40 tonnes to LEO depending on final configuration.
Angara A7
Proposals exist for a heavier Angara A7, weighing 1133 tonnes and capable of putting 35 tonnes into a x 60° orbit, or delivering 12.5 tonnes to GTO with an enlarged KVTK-A7 as a second stage in place of the URM-2. There are no current plans to develop this vehicle as it would require a larger core URM-1 to carry more propellant and would have to await the development of the hydrogen powered engine for KVTK. The Angara A7 would also require a different launch pad.

used a first stage derived from Angara's URM-1 (fitted with a lower-thrust version of the RD-191 engine called RD-151). The vehicle made its first flight on 25 August 2009. The flight was not successful, but the first stage operated as expected. A second launch on 10 June 2010 ended in failure, when contact with the rocket was lost 136 seconds after launch. The Joint Failure Review Board failed to come to a consensus on the cause of the failure. The third flight on 30 January 2013 successfully reached orbit.
