Up to date Could 12, 10:07 a.m. EDT (1407 UTC): The NRO confirms deployment of its satellites.
The Nationwide Reconnaissance Workplace flew its thirteenth mission supporting an intelligence-gathering constellation it calls the “proliferated structure” on Monday evening.
As with the primary dozen missions, this batch of satellites (of an undisclosed amount) flew to orbit on a SpaceX Falcon 9 rocket. The mission, dubbed NROL-172, launched from Area Launch Complicated 4 East at Vandenberg Area Pressure Base.
Liftoff occurred at 7:13:50 p.m. PDT (10:13:50 p.m. EDT / 0213:50 UTC), practically 4 hours after the opening of the window.
SpaceX launched the mission utilizing the Falcon 9 first stage booster with the tail quantity B1097. This was its ninth flight following the launch of the Twilight rideshare, Sentinel-6B, and 6 batches of Starlink satellites.
At 8.5 minutes after liftoff, B1097 landed on the drone ship, ‘Of Course I Nonetheless Love You’, positioned within the Pacific Ocean. This was the 196th touchdown on this vessel and the 610th booster touchdown thus far for SpaceX.
Given the character of reconnaissance operations, the NRO doesn’t provide a lot element on these satellites or specifics on their capabilities. It did state in its prelaunch press package that having a whole lot of satellites as a part of this constellation will “present better revisit charges and elevated protection, and get rid of single factors of failure.”
For this mission, the NRO did add some extra info by noting that its Geospatial Intelligence Techniques Acquisitions Directorate (GEOINT) is contributing to the satellite tv for pc constellation.
“GEOINT’s contribution to the NRO’s proliferated structure contains electo-optical, radar, and relay satellites,” the NRO mentioned. “Moreover, these relay satellites allow inter-satellite optical communications and function a key element of the NRO’s resilient communications structure in addition to the Division of Struggle’s (DoW) upcoming space-data community.”
The NROL-172 mission is the second flight booked on a Falcon 9 rocket as a part of the Nationwide Safety Area Launch (NSSL) Section 3 Lane 1 contract, managed by the US Area Pressure’s Area Techniques Command (SSC). The primary of these was the NROL-145 mission, which launchd on April 20, 2025.
The 2 missions had been assigned to SpaceX as a part of the NSSL Process Order (NTO)-2 on Oct. 18, 2024.
“The Lane 1 path is good for shorter, extra responsive mission timelines along with being the perfect entry avenue for potential NSSL suppliers,” mentioned USSF Col. Jim Horne, Launch Execution Senior Materiel Chief,” in a press launch on the time.
For the reason that launch of NROL-145, there have been two different missions supporting the proliferated structure constellation: NROL-48 on Sept. 22, 2025, and NROL-105 on Jan. 16, 2026. These two missions secured for launch onboard SpaceX Falcon 9 rockets by means of a procurement construction exterior of the SSC’s NSSL program
In an announcement to Spaceflight Now on Monday, a NRO spokesperson mentioned it typically used procurement constructions exterior of the NSSL contract, as a bridge between the conclusion of NSSL Section 2 and of Section 3 Lane 1. Like with all of the missions main as much as NROL-145, a NRO spokesperson mentioned each the NROL-48 and NROL-105 missions had been procured utilizing “the identical construction as with earlier proliferated launches.”
“Throughout a satellite tv for pc system acquisition lifecycle, value, schedule, and efficiency analyses are accomplished to find out one of the best ways to develop, purchase, launch, and function techniques to satisfy Intelligence Neighborhood and warfighter necessities,” the spokesperson mentioned. “Throughout these analyses, NRO makes selections to satisfy these necessities most effectively and successfully. For NRO’s proliferated structure, NRO acknowledged a bridge was wanted between Section 2 to Section 3 Lane 1. This resulted in some missions being procured exterior of NSSL. Going ahead, future proliferated structure missions can be launched with a mixture of NSSL Section 3 Lane 1 and missions procured by means of different acquisition automobiles.”
“The NRO has been a staunch supporter of NSSL since its inception and is dedicated to utilizing Nationwide Safety Area Launch (NSSL) Section 3 for main system acquisitions,” the NRO spokesperson mentioned. “The NRO is partnered with USSF Area Techniques Command’s Assured Entry to Area Workforce within the acquisition of Section 3 and influenced the event of Section 3, Lane 1 – as a method of procuring versatile launch options with tailorable mission assurance.”
“When contemplating our launch cadence and wish for tailorable mission assurance, the NRO acknowledged that we wanted a bridge between Section 2 to Section 3 – Lane 1. This resulted in some missions being procured exterior of NSSL. NSSL has, and can proceed to be, the NRO’s principal mechanism to acquire launch providers.”
