Fifth Tundra early warning satellite is in orbit

On 25 November 2021, at 04:09 MSK (01:09 UTC) crews of the Air and Space Forces conducted a successful launch of a Soyuz-2.1b launcher from the launch pad No. 43 of the launch complex No. 4 of the Plesetsk test site.

The satellite delivered into orbit (by a Fregat booster), was designated Cosmos-2552. It received international designation 2021-113A and registered by NORAD as object 49503.

The satellite will join the space-based segment of the early-warning system, known as EKS or Kupol. The spacecraft are known as Tundra. Cosmos-2552 is the fifth satellite of the system, which will eventually include ten satellites.

Previous launch of a Tundra satellite, Cosmos-2546, was conducted in May 2020.
