Soyuz‑2 (Russian : Союз‑2 , lit. 'Union‑2') (GRAU index : 14A14 ) is a modernized expendable medium-lift launch vehicle and the seventh major version of the Soyuz rocket family . It includes key enhancements over its predecessors, including improved engines along with digital flight control and telemetry systems, enabling launches from fixed platforms and the use of large payload fairings .
In its standard configuration, Soyuz‑2 is a three-stage launch vehicle designed for low Earth orbit missions. Notably, its stage numbering differs from some rockets. The boosters are considered its first stage, while the central core is the second. For higher orbits like Molniya or geosynchronous , an optional upper (fourth) stage can be added. The most common upper stage is the Fregat , but the smaller Volga is also an option. These upper stages have independent flight control and telemetry systems.
The Soyuz‑2 family has two major variants, with the Soyuz‑2.1a being the base version that first launched on 8 November 2004. The Soyuz‑2.1b , with a 15 percent more powerful third stage, followed on 27 December 2006. In 2011, the Soyuz‑ST was introduced, a derivative version with extensive modifications to launch from the Guiana Space Centre , the European Space Agency's spaceport in French Guiana. Soyuz launches from Guiana were suspended in 2022 after the Russian invasion of Ukraine . The derivative Soyuz-2.1v with a more powerful core stage and no boosters was introduced in December 2013.
The Soyuz‑2 rocket utilizes the existing facilities of its R-7 derived predecessors, Site 31/6 at the Baikonur Cosmodrome in Kazakhstan and Sites 43/3 and 43/4 at the Plesetsk Cosmodrome in northwestern Russia. In 2016, an additional launch location opened at Site 1S at the Vostochny Cosmodrome in eastern Russia.
The Soyuz‑2 has replaced the Molniya-M , Soyuz-U and Soyuz-FG rockets since 2010, 2017 and 2019 respectively.[ 11] [ 12] [ 13]
Variants
Soyuz 2.1a
The key advancement of the Soyuz‑2.1a is its digital flight control system, which replaces the analog system used in earlier Soyuz models.[ 4] This upgrade allows the rocket to adjust its trajectory mid-flight, a capability the analog system lacked, eliminating the need for a rotating launchpad. The digital system also supports the use of larger payload fairings, enabling the launch of heavier commercial satellites that the analog system could not handle due to the aerodynamic instability the fairings generate.[ 14]
The 2.1a retains the upgraded RD-107A engines on the first stage boosters and the RD-108A engine on the second stage core, initially introduced with the Soyuz-FG. These engines feature improved injection systems for enhanced performance.[ 4] [ 15] The only change for the Soyuz-2 is the addition of a chemical ignition system.[ 16] Previously, engines were ignited pyrotechnically with a pair of small charges placed on a wooden stick inside each of the 32 combustion chambers.[ 17]
The Block I third stage continues to use the RD-0110 engine, but its structure has been unified with the upgraded third stage of the 2.1b to streamline production. These changes slightly enlarged the propellant tanks, enabling longer burn times.[ 3] [ 14] The extra burn time combined with the physically lighter and more capable digital flight control system increased payload capacity by 300 kilograms (660 lb).[ 4]
The Soyuz‑2.1a conducted its maiden flight on 8 November 2004, launching from Plesetsk Cosmodrome Site 43 with a boilerplate payload simulating a Zenit-8 spy satellite.[ 4]
Soyuz 2.1b
The Soyuz‑2.1b has all the same features as the Soyuz‑2.1a but uses improved third stage built around the new RD-0124 engine which significantly increased specific impulse from 326 to 359 seconds (3.20 to 3.52 km/s), improving payload capability to low Earth orbit from 7,430 to 8,670 kilograms (16,380 to 19,110 lb) from the Baikonur Cosmodrome, for example.[ 18] [ 19]
The first launch of a Soyuz‑2.1b occurred from Plesetsk Cosmodrome Site 43 on 26 July 2008 with a classified military payload.[ 20]
Vostochny modifications
Modifications for the Vostochny Cosmodrome version of the Soyuz include the following:[ 21] [ 22]
Upgraded Computer : The system boasts six times more performance, reduced weight, and significantly simplified cable networks through multiplexing lines and the use of common buses.[ 23] [ 24] [ 25]
Improved Batteries : New nickel-cadmium batteries eliminate the need for a dedicated battery charging station.
On-Board Video System : A video system has been added, enabling real-time views of the launch.
Adaptation for Vertical Integration : Due to the mobile gantry at Vostochny, which supports vertical payload integration, the rockets are equipped with piping to direct oxygen purges outside the gantry.
On 1 October 2015, it was revealed that parts of the assembly complex for the Soyuz-2 at Vostochny Cosmodrome were designed for a different rocket modification and were too small. This issue raised doubts about the planned first launch in December 2015.[ 26] The first launch successfully took place on 28 April 2016.[ 27]
Notable missions
Suborbital test flight
On 8 November 2004, at 18:30 UTC, the first Soyuz‑2 rocket, in the Soyuz‑2.1a configuration, was launched from the Plesetsk Cosmodrome in Russia. The rocket followed a suborbital trajectory, with the third stage and Boilerplate landing in the Pacific Ocean .
Maiden launch
The first attempt at launching a Soyuz‑2 to orbit with the MetOp-A satellite occurred on 17 July 2006. It was scrubbed two hours before the launch by an automatic sequence after the onboard computer failed to check the launch azimuth. Fuelling of the rocket was underway at the time, and all launch complex equipment and onboard preliminary checks had proceeded without incident. The rocket was left fuelled on the launch pad for the next attempt on 18 July 2006. Launch was eventually conducted on 19 October 2006.
First crewed mission
The first crewed launch of Soyuz‑2 took place on 9 April 2020, carrying Soyuz MS-16 to the ISS.
Naphthyl fuel
Following successful ground testing, a naphthyl (Russian : нафтил) fueled Soyuz‑2.1b launch took place on 22 October 2022 at Vostochny. Naphthyl is an environmentally safe hydrocarbon fuel with fewer aromatic compounds than kerosene, which also slightly improves engine performance. There are only minor differences in thermal properties, viscosity, and surface tension, so this did not require significant engine changes.[ 28]
Launch statistics
Since 2006, Soyuz‑2 rockets have accumulated a total of 145 launches, 140 of which were successful, yielding a 97% success rate.
