## Why It Matters
Yamal 300K is a purpose-built communications satellite that adds capacity to the Yamal series operated by Gazprom Space Systems. As a geostationary communications satellite, it occupies a stable orbital slot relative to Earth’s surface, which is essential for continuous telecommunications services such as fixed satellite communications, broadcasting, and data relay. Its use of the Ekspress-1000NTA spacecraft bus and two solar arrays reflects a modular approach to satellite design that balances payload capability with launch mass constraints (1,870 kg). Launching on a Proton-M with a Briz-M upper stage from Baikonur continued established Russian heavy-launch practices for placing medium-class geostationary payloads into orbit. For operators and customers relying on satellite telecommunications infrastructure, Yamal 300K represents a component of national and commercial satellite capacity and contributes to the resilience and reach of satellite-based services managed by a major Russian operator.
