New Satellite Constellation To Launch By 2028 With Northrop Grumman

The Space Force plans to launch a new satellite constellation, called the Resilient Radar System-Ground (RRS-G), by 2028, which will be capable of tracking ground targets from orbit. The program is being built by Northrop Grumman, according to Space Force Lt. Gen. Gregory Gagnon. The Space Force has also established its first space-based sensing and tracking unit, the 77th Surveillance Squadron, to support the RRS-G mission. The service is working in parallel to develop satellites for airborne target tracking, with the first launch scheduled for this month. This development was first reported by Breaking Defense.
