## Why It Matters
Kosmos 311 serves as a historical data point within the extensive Soviet "Kosmos" satellite program, which encompassed a wide variety of military and scientific spacecraft. Launched in the late 1960s, this mission highlights the operational capabilities of the Soviet space industry during this era, specifically demonstrating the output of the Pivdenne Design Office. The use of the Kosmos-2I launch vehicle—a rocket described in records as a "superseded Soviet carrier rocket"—marks this mission as part of the transition period in Soviet aerospace technology. By successfully reaching orbit from the Plesetsk Cosmodrome, Kosmos 311 contributed to the extensive catalog of Soviet space assets, helping to establish the telemetry and orbital tracking records indexed under international systems like COSPAR. Its specific designation as part of the DSZ–P1–Ju class allows researchers to categorize the technological generations of Soviet satellite development during the Cold War.

## Notable For
- Being a specific unit (No. 27) of the DSZ–P1–Ju satellite class.
- Utilizing the Kosmos-2I rocket, a vehicle noted as a superseded model in launch history.
- Launching from Site 133 at the Plesetsk Cosmodrome, a major hub for Soviet orbital launches.
- Being tracked under the Wolfram Language entity code `Entity["Satellite", "04252"]`.

## Body
### Mission Profile and Classification
Kosmos 311 was a man-made orbital object classified as a Soviet satellite. It is formally categorized as an instance of the **DSZ–P1–Ju** class of spacecraft. In historical records and databases, it is often cross-referenced by its alias, **DS-P1-Yu No.27**. As part of the Kosmos program, its naming convention followed the standard Soviet practice of designating diverse satellites under a single collective name to obscure their specific military or scientific functions.

### Launch Details
The satellite was successfully launched on **November 24, 1969**. The precise moment of the rocket launch event was recorded at **11:00:04**.
- **Launch Site:** The mission originated from **Plesetsk Cosmodrome Site 133**, a primary launch complex located in the Soviet Union.
- **Launch Vehicle:** The carrier rocket used to propel Kosmos 311 into orbit was the **Kosmos-2I**. This rocket system is historically noted as a "superseded Soviet carrier rocket," indicating its use during a specific phase of Soviet aerospace development before newer models were adopted.

### Technical Identifiers
To facilitate international tracking and database management, Kosmos 311 is associated with several unique identifiers:
- **COSPAR ID:** 1969-102A
- **Satellite Catalog Number (SCN):** 04252
- **Freebase ID:** /m/076v_yz

### Manufacturing and Development
The design and construction of Kosmos 311 were attributed to the **Pivdenne Design Office**. This organization served as a key manufacturer for the Soviet space program. The mission represents a collaboration between the design bureau's hardware and the launch infrastructure provided by the Soviet Union's cosmodrome network.
