    Russia's flight test commission has decided to complete testing Soyuz-2.1a and Soyuz-2.1b rockets.

    MOSCOW (Sputnik) — Russia's flight test commission has decided to complete testing Soyuz-2.1a and Soyuz-2.1b rockets and to hand the launch vehicles over for operation by the Defense Ministry and Russian state corporation Roscosmos, the defense ministry said in a press release on Wednesday.

    "Flight tests of Soyuz-2 1a and 1b launch vehicles are completed. The decision was taken by the State Commission for conducting flight tests of manned space complexes. The commission's meeting concluded that flight tests of the Souyz-2 1a and 1b launch vehicle versions have been positive, and the flight test program has been fully executed," the release said.

    The flight test commission has also decided to complete testing the Fregat booster produced by the Lavochkin Research and Production Association. Both the Fregat booster and the Soyuz rockets will be transferred to the defense ministry and Roscosmos for operation, the release added.

    The Soyuz-2 rockets were developed starting from 2006. The 1a variant includes a digital control system in place of its analog predecessor, as well as an improved booster and fuel injection systems. It was first tested in 2011 at the Guiana Space Center.
