Soyuz-2.1a Launch Vehicle

Soyuz-2 launcher is based on the Soyuz-U series. Soyuz-2 features advanced engines and up-to-date control and telemetry systems that significantly enhance the LV technical and operational specifications. The upgrading was done in two phases. At phase 1а, a standardized Soyuz-2.1a was born to accommodate various upper composites with fairings of up to 4.11m in diameter. The LV is capable to orbit a payload with improved accuracy; the upgraded control system and stage I-II engines have allowed for increasing of the payload mass to be lofted to the low Earth orbit. At phase 1b resulted in Soyuz-2.1b, stage III was refitted with a state-of-the-art 14D23 (RD-0124) engine which made its performance even better.

The prime LV designer is Progress Space Rocket Center (the city of Samara). Depending on a mission, Soyuz-2 launcher can be configured with the Fregat upper stage.

Soyuz-2 key features:

- a new generation of a legendary carrier rocket;
- environmentally-friendly fuel of kerosene and liquid oxygen;
- increased performance and a state-of-the-art control system providing new orbiting capabilities.

Fregat Upper Stage

A standard Fregat upper stage was designed by Lavochkin Association to complement various launchers in order to put satellites in different orbits. It is used in Soyuz rockets. A standard Fregat upper stage equipped with extra fuel tanks or drop-off tanks evolved to highly efficient upper stage modifications: Fregat-MT and Fregat-SB.

Fregat key features:

- independence – the upper stage orbits a payload without uplink control;
- the logic of upper stage operation provides for responding to potential anomalies;
- satellite navigation instruments in the control loop improve spacecraft insertion accuracy;
- lengthy active life (up to 2 days);
- operations at Baikonur, Plesetsk, the Guiana Space Center and, in the future, at Vostochny.
