GSSAP 7 & 8 (Hornet 7 & 8)

Geosynchronous Space Situational Awareness Program (GSSAP) satellites are a space-based capability operating in the near-geosynchronous orbit regime, supporting U.S. Space Command space surveillance operations as a dedicated Space Surveillance Network (SSN) sensor.

Propulsive ESPA

Also onboard USSF-87 is a propulsive ESPA-Ring carrying research, development, and training systems that USSF Guardians will use to refine tactics, techniques and procedures for precision on-orbit maneuvers, as well as enhance and validate resiliency and protection in geosynchronous orbit. This will be the aft-payload.
