On 18 September 2026, the Air and Space Forces conducted a successful launch of a Soyuz-2.1b rocket from the Plesetsk space launch site (Ministry of Defense video; also on YouTube). The launch took place at about 19:50 MSK (16:50 UTC). The satellite that the rocket and its Fregat boost stage delivered into orbit is believed to be a Glonass-K navigation satellite.

The satellite is likely to be designated Cosmos-2620. It received the international designation 2026-216A and was registered in the NORAD/Space-Track catalog as object 100744. At this point the Space-Track catalog lists the satellite as Object A.

The previous launch of a Glonass-K satellite took place in August 2026.
