“The first launch of the Soyuz-2.1V rocket has been preliminarily scheduled for the second half of this year,” Progress design bureau’s general director Alexander Kirilin said.

He did not specify the reasons for the delay.

Russia originally planned to launch the first Soyuz-2.1V in October 2012 but that was postponed after a failed ground test of its first-stage engines in August, Progress said.

In December 2012, the commander of Russia’s Aerospace Defense Forces, Maj.Gen. Alexander Golovko, said the first Soyuz 2.1V launch would take place at the start of 2013.

The new rocket is a modernised version of the Soyuz-2.1B, from which the Soyuz rocket’s trademark four external booster rockets have been removed.

The first stage is equipped with a rocket engine derived from the legendary NK-33, according to the Plesetsk cosmodrome website.

The NK-33 was developed in the 1970s to carry Soviet cosmonauts to the moon onboard the giant N1 rocket.

The rocket is capable of delivering a payload of up to 2.85 tonnes to an orbit at an altitude of 200 km, Progress claims.

Soyuz-2.1V launches may be carried out from upgraded launch pads at the Plesetsk Space Center in northwestern Russia and the Baikonur Space Center in Kazakhstan.
