## Why It Matters
Cosmos 313 is a concrete example of the Zenit 2M series of Soviet reconnaissance satellites. As a Zenit 2M-class vehicle, it represents the Soviet Union’s deployment of dedicated photographic/electro-optical spy satellites during the era when such systems were a primary source of national intelligence collection from space. The satellite’s recorded identifiers (COSPAR 1969-104A and SCN 04262) and its launch from Plesetsk on a Voskhod rocket place it within Soviet operational launch infrastructure and cataloging systems. Entries like Cosmos 313 are important for historical records, technical catalogues, and the study of spaceflight logistics because they link vehicle class, launch hardware, site, and precise event timing. They also enable cross-referencing across international databases (e.g., Wolfram Language entities and multilingual encyclopedic coverage), which supports research into satellite programs, launch frequency, and the composition of reconnaissance satellite fleets.
