## Why It Matters
Cosmos 1611 serves as a specific historical data point within the extensive Soviet "Cosmos" program, which designated a vast array of military and scientific satellites. As an instance of the Yantar-4K2 platform, this entity represents the technological continuation of Soviet photoreconnaissance capabilities during the mid-1980s.

The entry is significant for space history researchers and orbital analysts because it documents the precise use of the "Gagarin's Start" launch complex—the site of Yuri Gagarin's historic flight—for a military reconnaissance mission. The detailed metadata associated with Cosmos 1611, including its specific SCN (15403) and exact launch time (10:30:00), contributes to the accuracy of orbital debris tracking and historical spaceflight catalogs. Furthermore, the mission highlights the reliance on the Soyuz-U launch vehicle, a workhorse of the Soviet and Russian space programs, for deploying critical intelligence infrastructure.

## Notable For
*   **Specific Classification:** It is a documented example of the Yantar-4K2 ("Oktan") reconnaissance satellite series.
*   **Historic Launch Site:** The mission utilized "Gagarin's Start," the same launch pad used for the first human spaceflight.
*   **Precise Tracking:** The entry includes a precise launch time (10:30:00) and a specific Wolfram Language entity code (Entity["Satellite", "15403"]), indicating its cataloging in major scientific databases.
*   **Soyuz-U Utilization:** It exemplifies the use of the Soyuz-U "Universal" rocket variant for deploying medium-weight military payloads.

## Body

### Mission Profile and Classification
Cosmos 1611 was a man-made object launched into orbit under the Soviet Union's Kosmos program. The program was used to mask the true nature of military reconnaissance satellites. Cosmos 1611 was specifically an instance of the **Yantar-4K2** class, a type of spy satellite used by the Soviet and Russian forces. The Yantar-4K2 series was designed for detailed photographic reconnaissance.

### Launch Details
The satellite successfully achieved orbit following a rocket launch on **November 21, 1984**. The launch took place at **10:30:00**.
*   **Launch Vehicle:** The mission was carried out by a **Soyuz-U** rocket. The Soyuz-U is a variant of the original Soyuz launcher, noted for its "Universal" design capability to carry both crewed and uncrewed payloads.
*   **Launch Site:** The launch originated from **Gagarin's Start** (Baikonur Cosmodrome), historically significant as the launch site of Vostok 1.
