On June 16, 2018 UTC (June 17 Moscow time), the Air and Space Forces performed a successful launch of a Soyuz-2.1b rocket from the launch pad No. 4 of the launch complex No. 43 of the Plesetsk space launch site. The launch took place at 00:46 MSK (21:46 on 16 June 2018 UTC). The satellite that the rocket and its Fregat boost stage delivered into orbit is a Glonass-M navigation satellite. The satellite is likely to be designated Cosmos-2527. The satellite received international designation 2018-053A and was registered by NORAD as object 43508.

Normally, Glonass satellites as well as other military satellites receive Cosmos designation when the ground command center establishes control over the satellite. On 21 June 2018 the Air and Space Forces reported that the control was established. However, the designation has not been announced yet. [UPDATE: According to NK it is indeed Cosmos-2527.]

Previous Glonass launch took place in September 2017.
