Soyuz 2.1b | Kosmos 2572 (Razdan No. 1?)

Note: Payload identity and Cosmos series number uncertain.

The Razdan satellite is reportedly a new electro-optical reconnaissance satellite designed as a successor to the Persona (Kvarts) satellites.

Reportedly Razdan will feature a significant improvement over the capabilities of its predecessors, including a new high-speed secure radio channel.

Razdan features a LOMO-built optical system. The third satellite will be the first to carry a new 2 meter mirror optics that will be built by the Zverev factory in Krasnogorsk.
