A Falcon 9 rocket rumbled its way off the launch pad at Vandenberg Space Force Base Monday morning to carry a payload for the nation’s spy satellite agency.

The SpaceX rocket blasted off at 10:38 a.m. from Space Launch Complex-4.

Less than eight minutes later, the first-stage booster completed its 18th mission and successfully landed at Vandenberg, generating sonic booms heard in parts of Santa Barbara County. 

The purpose of Monday’s mission was to place the National Reconnaissance Office payload into orbit.

The agency remained mum about the number of satellites on board the mission dubbed NROL-48.

However, the Starshield craft used the same satellite frame as Starlink which typically involves 20-24 space vehicles per mission.

NRO also remained mum about the specific job of the satellites in the agency’s intelligence, surveillance and reconnaissance roles. 

Like other satellite operators, NRO has switched to deploying a constellation of smaller craft with the mission marking the 11th overall launch of the NRO’s proliferated architecture and fifth proliferated launch of 2025. 

“Having hundreds of NRO satellites on orbit is vital to our nation and partners. This constellation continues to add capability and resilience to our mission through shorter revisit times, increased observational persistence, and faster processing and transmission of data,” NRO representatives said.

NRO, like other operators, previously built and launched behemoth spacecraft every several years, but a launch flop or on-orbit satellite failure left a gap in the capabilities.

“Over the past two years, NRO has launched more than 200 satellites, creating the largest and most capable government constellation on orbit in our nation’s history,” representatives said.

This was the fifth dedicated NRO mission from Vandenberg this year. 

Additional launches of the proliferated architecture system are planned through 2029, NRO representatives said.

SpaceX plans to conduct another Starlink mission as soon as Wednesday with the launch window spanning from 6:57 p.m. to 10:57 p.m. For that mission, the first-stage booster will land on the droneship in the Pacific Ocean.
