#NROL146 is scheduled to launch on a @SpaceX Falcon 9 rocket from Vandenberg Space Force Base (@SLDelta30) May 19! This is the first launch of NRO’s proliferated architecture, delivering critical space-based ISR to the nation.

This is the first batch of satellites for a reconnaissance satellite constellation built by SpaceX and Northrop Grumman for the National Reconnaissance Office.

Gen. Stephen Whiting, #USSPACECOM commander, hosted the Spring 2024 Commander’s Conference where component command teams, joint directors, and experts discussed major planning efforts, advancing USSPACECOM’s mission to deter aggression in space.

Troy Meink, principal deputy director, spoke about #NROL146 at Space Symposium 39, “This launch will be the first launch of an actual operational system. This system will increase timeliness of access, diversity of communication paths and enhance our resilience.”
