## Why It Matters
Kocmoc-2550 represents one of the incremental but essential flights that keep Russia’s civil and military satellite constellations replenished. While the mission payload details remain undisclosed, the use of the Soyuz-2.1b—an upgraded digital-control variant—signals continued reliance on proven launch infrastructure amid Russia’s broader push toward Angara-class vehicles. Each successful insertion, even when sparsely documented, sustains cadence for Baikonur cosmodrome operations, preserves industrial workforce skills, and maintains orbital slots that can later host communications, Earth-observation, or experimental platforms. For historians, the 2021 launch adds another data point to the post-Soviet launch log, illustrating how legacy naming conventions (“Kocmoc” = “cosmos”) persist into the 2020s.

## Notable For
- One of the few 2021 Russian missions whose official name begins with “Kocmoc” rather than a civilian or commercial brand
- Sole flight in the public catalogue bearing the COSPAR ID 2021-056A
- Documented exclusively through Russian-language Wikipedia, limiting international visibility

## Body
### Launch Event
Kocmoc-2550 lifted off from Baikonur Cosmodrome on 25 June 2021 at 19:50 UTC. The Soyuz-2.1b launch vehicle placed the spacecraft into its predetermined orbit, completing the rocket-launch phase.

### Identification
The spacecraft is registered internationally as 2021-056A and domestically under serial number 48865. Both identifiers are used by space-surveillance networks for tracking and cataloguing.

### Platform
Soyuz-2.1b is a digital flight-control upgrade of the Soyuz-2 line, offering improved injection accuracy over earlier analogue systems.
