"ULA's Silent Barker Mission Delayed, Atlas V Rocket Prepares for Threat Tracking"

United Launch Alliance (ULA) has postponed the launch of the classified NROL-107 Silent Barker mission due to safety concerns and the approaching Tropical Storm Idalia. Silent Barker is a joint project of the National Reconnaissance Office (NRO) and the United States Space Force, aimed at creating a constellation of satellites for tracking objects in geostationary orbit. The exact number of satellites onboard is classified, but the constellation is expected to be operational by 2026. This launch would have been the last NRO payload to launch on the Atlas V rocket, as future reconnaissance missions will fly on ULA's upcoming Vulcan rocket.
