## Why It Matters
Cosmos 1743 is a documented instance of the Tselina-D series, a class explicitly described as Soviet signals intelligence satellites. As such, the spacecraft is part of a broader space-based intelligence capability used to intercept, monitor, or otherwise collect electronic and communications signals for national security and intelligence purposes. The recorded launch details — date, site, vehicle, COSPAR ID, and catalogue number — make Cosmos 1743 a traceable element of Soviet-era space operations and satellite registry records. That traceability supports historical research, spaceflight databases, and the cataloguing of military and intelligence-related space assets. For analysts and archivists, precise identifiers like COSPAR ID (1986-034A) and SCN (16719), together with launch metadata, enable cross-referencing across technical catalogs (for example, the Wolfram Language entity identifier) and multilingual documentation, as reflected in available Wikipedia sitelinks.
