The US Space Force (USSF) is developing new surveillance satellite constellations using 'free flyer' space vehicles (SVs) that emulate unmanned aircraft system swarms. Industry input for this initiative was submitted to USSF officials in January 2026, following a request for information issued in November 2025.

The primary goal of the proliferated constellation is to autonomously search for, detect, and monitor Resident Space Objects (RSOs) in geosynchronous orbit. The SVs will function with existing command-and-control platforms to support operational needs.

These free flyer SVs, similar in size to mini or nanosatellites, have been previously utilized by NASA for civilian space operations. They will be deployed via larger host satellites and are intended for missions that include RSO monitoring and space situational awareness.
