Cosmos 2513

The Russian Garpun military relay satellites are the replacement for the Potok / Geizer series for the nation's Command and Relay System (GKKRS) which is also known as Rassvet. The satellites are developed by ISS Reshetnev, probably based on the Ekspress-2000 bus. Likely users for the Garpun satellite are Persona and Bars-M optical reconnaissance satellites and the Pion-NKS and Lotos-S ELINT satellites.
