Soyuz 2.1b
The 2.1b version adds an upgraded engine (RD-0124) which greatly increases the specific impulse of the upper stage (326 seconds to 359 seconds), and hence improves payload capability from 7 tonnes to 8.2 tonnes. First launch took place from Plesetsk Cosmodrome Site 43 on 26 July 2008 with a classified military payload. The 2.1b/ST version is sometimes called Soyuz ST-B. The first launch, from Centre Spatial Guyanais, was a success (21 October 2011), for the first two Galileo IOV satellites.
The Fregat upper stage is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit. Fregat is a versatile upper stage, in addition to orbital insertion, it can be used as an escape stage to send modern space probes into interplanetary trajectories (e.g. Venus Express and Mars Express). Fregat stages are currently used as the fourth stage of some Soyuz launch vehicles. The stage can be restarted up to 7 times.

@WarThunder88 I marked where you should put the apoapsis and the periapsis in edit program.
