Soyuz-2-1v Volga (Soyuz-1 Volga)
The Soyuz-2-1v (formerly called Soyuz-1) is a lightweight derivative of the Soyuz launch vehicle. It ommits the four strap-on boosters and features a modified core. While originally the core with a NK-33-1 engine was planned, the core had to modified to a larger diameter, when the development of the NK-33-1 was cancelled and replaced with a RD-33 and an additional RD-0110 vernier engine.
The first flight is planned for 2012 from Plesetsk.
