## Why It Matters
SECS serves as a specific case study in the deployment of military assets during the post-Cold War era. Launched in April 1990, the satellite represents the utilization of the Pegasus launch system, an air-launched rocket technology incepted in 1987 that offered flexible deployment options for space payloads.

As a military satellite, SECS fits into the broader category of artificial satellites used for defense and strategic purposes. Its documentation in knowledge bases via specific identifiers like the COSPAR ID (1990-028B) and Satellite Catalog Number (20547) illustrates the rigorous tracking and cataloging required for objects in Earth's orbit. The existence of data regarding its launch vehicle and date helps historians and analysts map the evolution of launch technologies and military space infrastructure.

## Notable For
- Being a specialized military satellite deployed for defense purposes.
- Utilizing the Pegasus air-launched rocket system for deployment.
- Possessing a specific tracking record in international satellite catalogs (SCN 20547).
- Being part of the 1990-028 launch mission (designated as the 'B' component).

## Body
### Classification and Purpose
SECS is classified as a military satellite. According to structured knowledge sources, this class of object is defined as an "artificial satellite used for military purpose." While specific mission details regarding its sensors or communications relay are not detailed in the provided source, its classification places it within the domain of national security and defense space assets.

### Launch and Deployment
The satellite was successfully launched on April 5, 1990. The launch event is noted as a significant milestone in the object's timeline.

**Launch Vehicle:**
The deployment of SECS was facilitated by the Pegasus rocket. The Pegasus system is notable as an air-launched rocket class, a technology that was established in 1987. This method of launch involves the rocket being carried to altitude by a carrier aircraft before being released to ignite its engines and propel the payload into orbit.

### Identification and Tracking
SECS is tracked through several standard astronautical identifiers:
- **COSPAR International Designator:** 1990-028B. This code indicates the year of launch (1990), the launch number of the year (028), and the specific component of the launch (B).
- **Satellite Catalog Number (SCN):** 20547. This is a sequential identifier assigned by the US Space Command.
- **Google Knowledge Graph ID:** /g/1q61gdvz7.
- **Wikipedia Presence:** The entity is documented in the German language edition of Wikipedia (`de`).
