## Why It Matters
Cosmos 315 is part of the Soviet Tselina-OM series, a family of satellites explicitly associated with signals intelligence. As such, it represents a piece of Cold War-era spaceborne reconnaissance capability. Launches like Cosmos 315 demonstrate the Soviet Union’s use of dedicated orbital platforms for electronic intelligence collection, contributing to national situational awareness and strategic monitoring. The satellite’s launch from Plesetsk Cosmodrome on 20 December 1969 using a Kosmos-3M rocket places it within the broader operational cadence of Soviet military and intelligence space programs. Identifiers such as COSPAR 1969-107A and SCN 04273 allow researchers and catalogers to track the object across international space object registries and scientific databases (including entries in knowledge graphs and computational knowledge systems).
