SpaceX Schedules Third NRO Mission of the Year

A Falcon 9 rocket now stands ready at Vandenberg Space Force Base for another National Reconnaissance Office flight that will expand the agency’s intelligence-gathering network in low Earth orbit.

Launch details are set for early Friday morning. Liftoff from SLC-4E is targeted during a 35-minute window opening at 1:40 a.m. PDT on Friday, June 19. Spaceflight Now plans live coverage starting roughly 30 minutes before the rocket leaves the pad.

The flight, designated NROL-179, forms part of the NRO’s proliferated architecture constellation. An undisclosed number of satellites will ride to orbit.

The satellites are believed to be Starshield variants. Neither the NRO nor SpaceX has confirmed on the record that these are government-modified versions of the Starlink design. The agency has stated it aims for “hundreds of small satellites on orbit” in order to “provide greater revisit rates and increased coverage. And even eliminate single points of failure.”

This marks SpaceX’s 14th launch for the NRO’s low Earth orbit constellation. It counts as the third such mission in 2026. Officials have released few specifics on the final size or full architecture of the network.

The booster B1103 will fly for the third time. The stage first flew on Starlink 17-35 in April and again on Starlink 17-42 in May. It is expected to land at Landing Zone 4 in California less than eight minutes after launch.

A successful touchdown would mark the 35th landing at that site and the 626th booster recovery by SpaceX overall.

The NRO’s proliferated architecture includes contributions from its Geospatial Intelligence Systems Acquisitions Directorate. “GEOINT’s contribution to the NRO’s proliferated architecture includes electro-optical, radar, and relay satellites,” the agency wrote in its prelaunch press kit. Those relay satellites also support inter-satellite optical links that form part of both the NRO’s resilient communications network and the Department of War’s planned Space-Data Network.
