Soyuz-2 (GRAU index 14A14) is a modernized expendable medium-lift launch vehicle and the seventh major version in the Soyuz 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.
Soyuz-2.1b has all the same features as the Soyuz-2.1a, but uses an upgraded engine (RD-0124) on the third stage, which greatly increases specific impulse (326 to 359 seconds), improving payload capability to LEO from 7,200 kilograms (15,900 lb) to 8,200 kilograms (18,100 lb). When configured with the larger ST fairing, the Soyuz 2.1b is sometimes called Soyuz ST-B.
