## Why It Matters
Cosmos 1815 represents a specific orbital deployment within the Soviet Union's space program during the late 1980s. As a Rhombus-class satellite, it serves as a data point in the historical record of Soviet satellite technology and orbital assets. Its launch from Kapustin Yar using the Kosmos-3M rocket highlights the operational infrastructure of the era, specifically the reliance on the Kosmos-3M vehicle for placing specialized payloads into space. 

The satellite is cataloged under the international COSPAR ID 1987-007A and SCN 17326, which allows for precise tracking and historical analysis of Soviet space activities. While specific mission objectives for the Rhombus class are not detailed in the primary record, the successful deployment of Cosmos 1815 contributes to the overall service history of the Kosmos-3M rocket, which is a notable entity in Russian and Soviet aerospace history. Understanding these individual launches is essential for researchers and historians reconstructing the timeline of late-Cold War era space operations and the proliferation of the Rhombus satellite series.

## Notable For
- **Satellite Classification:** It is a member of the Rhombus class of satellites.
- **Launch Vehicle:** Utilized the Kosmos-3M, a rocket class associated with both the Soviet Union and Russia.
- **Geographic Origin:** Launched from Kapustin Yar, a major Soviet launch facility.
- **International Tracking:** Recognized by the COSPAR ID 1987-007A and the Wolfram Language entity code Entity["Satellite", "17326"].

## Body

### Mission and Launch
Cosmos 1815, also known as Kosmos 1815, was successfully launched on January 22, 1987. The significant event of the rocket launch was recorded at 07:00:00 UTC. The mission originated from the Kapustin Yar launch site, a key facility for Soviet space operations.

### Technical Identification
The satellite is tracked and identified through several standardized systems:
*   **SCN:** 17326
*   **COSPAR ID:** 1987-007A
*   **Wolfram Language Code:** Entity["Satellite", "17326"]

### Launch Vehicle and Classification
The satellite is classified as an instance of the Rhombus class. The vehicle responsible for its delivery into orbit was the Kosmos-3M rocket. This rocket is a well-established Russian/Soviet class of launch vehicle, noted for its extensive use in deploying various satellite series. The Kosmos-3M itself is a highly documented entity with a sitelink count of 16 across different information platforms. 

### Historical Context
At the time of its launch in 1987, Cosmos 1815 was part of the ongoing space efforts of the Soviet Union. Its presence in international databases and its association with the Rhombus class link it to a broader category of orbital hardware utilized during this period. The satellite currently maintains a sitelink count of 3, with Wikipedia entries available in the Macedonian (mk), Serbo-Croatian (sh), and Serbian (sr) languages.
