Soyuz-2-1a rocket variant

The initial version of the upgraded Soyuz-2 vehicle, known as Soyuz-2-1a (14A14), featured a four-meter payload fairing. It was capable of carrying 300 kilograms more payload than its predecessor variants thanks to the replacement of an old analog flight control system with a digital computer and the use of a more flexible launch trajectory. In 2012, the KBKhA design bureau in Voronezh promised to develop the 11D55 steering engine specifically for the Soyuz-2-1a rocket.

According to the Russian mission control in 2024, the three-stage Soyuz-2-1a rocket variant, likely referring to the crew-certified vehicle, had a full length of 46.3 meters and a (maximum) diameter (at the base of the first stage) of 10.3 meters. The rocket's liftoff mass could vary from 306 to 313 tons.

The mission control also listed the following payload capabilities of the Soyuz-2-1a variant when launched from Baikonur:

Payload to the low Earth's orbit: 6-8 - 7.4 tons;
Payload to the Sun-synchrononous orbit: 4.3 - 4.5 tons;
Payload to the geostationary transfer orbit: 1.5 tons.

Payload spefications of the Soyuz-2-1a rocket variant according to its manufacturer, RKTs Progress:
