## Why It Matters
Cosmos 2117 serves as a historical example of the Soviet Union's satellite deployment strategies during the final years of the Cold War era. As part of the Strela-3 class, it represents the technological progression of military communications capabilities, transitioning from earlier systems to more robust networks. The entry highlights the collaboration between Soviet and Ukrainian space industries (the Strela-3 being a Ukrainian class and the Tsyklon-3 a Soviet/Ukrainian vehicle), a distinction that became geopolitically significant following the dissolution of the Soviet Union shortly after this launch. By documenting specific identifiers like the COSPAR ID (1990-114D) and SCN (21031), this entity remains a verifiable data point in the global catalog of man-made space objects, assisting astronomers and space agencies in tracking orbital debris and historical assets.

## Notable For
- **Military Utility:** Being a specific instance of the Strela-3 class, dedicated to military communications.
- **Launch Precision:** Having a recorded launch time precise to the second (07:28:53).
- **Historical Context:** Launching in late 1990, shortly before the dissolution of the Soviet Union.
- **Multi-Lingual Presence:** Having documented Wikipedia entries in Croatian (hr), Macedonian (mk), Serbo-Croatian (sh), and Serbian (sr).
