Orbital launch vehicle. Other Family:

Version of the Soyuz proposed with an Ariane 4 or Russian Lox/LH2 upper stage.

In order to achieve a payload double that of the current vehicle, it would seem a high-energy Lox/LH2 upper stage would be needed. Such an improvement was proposed as far back as July 1962 (the Molniya 8K78L) but never developed. The version with the Ariane 4 upper stage would be capable of putting 3900 kg into geosynchronous transfer orbit when launched from Kourou.

Manufacturer: Korolev. Payload: 3,900 kg (8,500 lb). to a: geosynchronous transfer orbit, 1 deg inclination, trajectory.
