The Soyuz STA Fregat was manufactured by Progress Rocket Space Center with the first launch on 2011-12-17. Soyuz STA Fregat has 8 successful launches and 0 failed launches with a total of 8 launches. The 2.1a version includes conversion from analog to digital flight control system and uprated engines on the booster and the first stage with improved injection systems. The new digital flight control and telemetry systems allow the rocket to launch from a fixed rather than angled launch platform and adjust its heading in flight. A digital control system also enables the launch of larger commercial satellites with wider and longer payload fairings such as the ST-type fairing. These fairings introduce too much aerodynamic instability for the old analog system to handle. This stage continues to use the RD-0110 engine.

The 2.1a/ST version is sometimes called Soyuz ST-A.
