Kosmos 2474 was launched from Site 43/4 at Plesetsk Cosmodrome in northern Russia. A Soyuz-2-1b carrier rocket with a Fregat upper stage was used to perform the launch which took place at 20:15 UTC on 2 October 2011. The launch successfully placed the satellite into Medium Earth orbit. It subsequently received its Kosmos designation, and the international designator 2011-055A.

It was due to be launched on 25 August 2011 but was postponed due to the failed launch of Progress M-12M the day before. It was rescheduled to 25 September, and then to 1 October before being launched on 2 October.
