A classified Russian military satellite in geostationary orbit. Russia routinely launches highly capable military satellites under the Cosmos designation, which provides a level of ambiguity about their missions. COSMOS 2520's orbital position is monitored by independent tracking organizations, but its specific capabilities remain undisclosed. Russia's classified GEO presence mirrors the US approach of maintaining unacknowledged national security payloads in the strategic geostationary belt.
