## Why It Matters
Cosmos 1599 is a concrete example of the Yantar-4K2 reconnaissance satellite program operated by the Soviet Union. As an operational Yantar-4K2 satellite launched in 1984, it illustrates the continued use of the Soyuz-U launch vehicle and the Plesetsk Cosmodrome launch complex for space reconnaissance activities during that period. Its catalog identifiers (COSPAR 1984-102A and SCN 15318) and presence in scientific and database systems (for example, a Wolfram Language entity) make it a traceable datum in satellite catalogs and historical records of Soviet space operations. For researchers tracking the deployment, launch cadence, and platform variants of Cold War-era reconnaissance satellites, Cosmos 1599 provides a dated, well-documented instance tying together the Yantar-4K2 spacecraft, the Soyuz-U launcher, and Plesetsk Site 43/4 launch infrastructure.
