## Why It Matters  
Cosmos 1794 represents a component of the Soviet Union’s strategic communications infrastructure during the Cold War. As a Strela‑1M satellite, it contributed to a constellation that enabled secure, low‑latency data transmission for military units across the vast Soviet territory, enhancing command‑and‑control capabilities. Its launch from the Plesetsk Cosmodrome—a key northern launch site—demonstrates the USSR’s reliance on inland launch facilities to protect sensitive missions from foreign observation. Understanding Cosmos 1794 helps illustrate the evolution of space‑based communications, the technical choices (such as the reliable Kosmos‑3M launcher), and the broader geopolitical context of satellite deployment in the 1980s. For historians of space technology and defense analysts, the satellite offers a concrete example of how orbital assets were integrated into national security strategies before the post‑Cold‑War transition to commercial and civilian satellite services.  

## Notable For  
- Being a Strela‑1M satellite, part of a series that provided the Soviet military with a dedicated low‑Earth‑orbit communications network.  
- Launching from the strategically important Plesetsk Cosmodrome Site 132, highlighting the USSR’s use of inland launch complexes.  
- Utilising the Kosmos‑3M launch vehicle, a workhorse rocket known for its reliability in placing small to medium payloads into orbit.  
- Carrying the COSPAR ID 1986‑092A and catalog number 17138, which uniquely identify the mission in international space tracking databases.  
- Having multilingual Wikipedia coverage (mk, sh, sr), indicating regional interest and documentation across former Soviet states.  

## Body  

### Overview  
Cosmos 1794 (Kosmos 1794) is a Soviet‑built communications satellite classified under the Strela‑1M series. The Strela‑1M constellation was designed for store‑and‑forward data relay, supporting military communications across the USSR’s extensive landmass.  

### Launch Details  
- **Date & Time:** 21 November 1986, 02:00 UTC.  
- **Site:** Plesetsk Cosmodrome, Site 132, located in north‑western Russia.  
- **Vehicle:** Kosmos‑3M, a two‑stage launch rocket frequently used for small to medium payloads.  
- **Event:** The launch is recorded as a “rocket launch” significant event, confirming successful insertion into low‑Earth orbit.  

### Satellite Classification  
- **Instance of:** Strela‑1M, a class of low‑Earth‑orbit (LEO) communication satellites.  
- **Purpose:** Provide secure, rapid data transmission for military users; operate as part of a larger network of similar satellites.  
- **Identifiers:**  
  - COSPAR ID: 1986‑092A.  
  - Satellite Catalog Number (SCN): 17138.  

### Operational Context  
The Strela‑1M series, including Cosmos 1794, formed a backbone for Soviet tactical communications, enabling ground units to exchange messages without reliance on terrestrial infrastructure. Their LEO placement allowed for relatively short communication delays and global coverage when multiple satellites were active.
