We don't know much about the newly lofted satellites because the NRO doesn't disclose much about its orbiting assets. However, the proliferated architecture craft are thought to be modified versions of SpaceX's Starlink internet satellites that have been outfitted with high-tech spy gear.

All nine of the proliferated architecture missions have flown on Falcon 9 rockets out of Vandenberg. They have also come in rapid succession; the first one launched in May 2024.
