According to the article published on russianspaceweb.com, the fully-assembled Angara-A5 was loaded with fuel on December 15, and was rolled out to the rocket’s launch pad two days later. The same source also mentions that preparations for this launch were conducted in secrecy an no official live coverage was provided.

The liftoff of the new rocket vehicle took place in Plesetsk cosmodrome. Just after the launch Russian officials confirmed that the rocket had successfully reached an initial parking orbit 12 minutes after the rocket took off from the launch site.

Angara-A5 has a three-stage design. At the moment of the third stage separation, the vehicle contained a 25 766 kilogram payload which also included a dummy satellite weighing 2042 kg. The payload was delivered to a 215 km circular orbit. Later, after three successive upper stage orbital insertion rocket engine Briz-M firings the vehicle reached the orbit at an altitude of 35 801 kilometers, which was slightly above the true geostationary orbit that was intended to be reached according to original plans.

During the entire mission the dummy cargo remained attached to the rocket platform. After reaching the peak altitude, two maneuvers were completed to evade a busy traffic of the geostationary orbit.
