Update: The ninth GPS III satellite was successfully launched into orbit Tuesday.
Pre-launch report
GPS III Space Vehicle SV09 is being prepped for launch from Space Launch Complex (SLC)-40 at Cape Canaveral Space Force Station, Florida, aboard a SpaceX Falcon 9 rocket.
The launch, delayed from Jan. 25, is now scheduled for 11:38 p.m. ET on Tuesday, Jan. 27.
A live webcast of this mission from launch to satellite deployment will begin about ten minutes prior to liftoff and can be watched on www.spacex.com/launches. The webcast will be shown on the X TV app, as well as various streaming outlets, including YouTube.com via SpaceFlight Now and NASASpaceflight.com.
U.S. Space Force’s Space Systems Command (SSC) and Combat Forces Command (CFC) will launch SV09 as the next National Security Space Launch (NSSL). The two field commands are executing this mission using the model established by the Rapid Response Trailblazer launch in December 2024 and GPS III-7 (SV08) launch in May 2025. Being pre-postured with the right equipment has enabled the launch teams to process and integrate the GPS III (SV09) satellite with the Falcon 9 rocket on a shortened timeline, the Space Force said.
GPS III satellites, equipped with M-code technology, provide the warfighter with a significantly more accurate and jam-resistant capability. Adding another such satellite to the constellation enhances the system’s robustness and ultimately boosts the warfighting lethality of the Joint Force.
“For this launch, we traded a GPS III mission from a Vulcan to a Falcon 9, then exchanged a later GPS IIIF mission from a Falcon Heavy to a Vulcan,” said USSF Col. Ryan Hiserote, SYD 80 Commander and NSSL program manager. “Our commitment to keeping things flexible – programmatically and contractually –means that we can pivot when necessary to changing circumstances. We have a proven ability to adapt the launch manifest to complex and dynamic factors and are continuing to shorten our timelines for delivering critical capabilities to warfighters.”
The space vehicle was successfully delivered to Florida over-the-road on July 31, 2025. Now, CFC’s Mission Delta 31 is leading the pre-launch processing of the space vehicle, working alongside Lockheed Martin to integrate it onto the rocket and for launch in a faster timeline than in the past.
“This mission represents an outstanding collaboration across multiple teams and agencies,” said U.S. Space Force Col. Stephen Hobbs, MD 31 commander. “It foot stomps our ability to rapidly deploy a high-value space asset, in this case, an additional M-Code-capable satellite that brings significant, immediate value to the Joint Force.”
SV09 is named in honor of Col. Ellison Onizuka, a U.S. Air Force test pilot and NASA astronaut. Onizuka successfully flew on STS-51C, a space shuttle Discovery mission in January 1985. The naming of the satellite also honors his memory as one of the astronauts who perished during the launch of STS-51L aboard the space shuttle Challenger on Jan. 28, 1986.
With the launch of SV09, the GPS III constellation gains another satellite equipped with significantly enhanced accuracy and jam-resistance, bolstering the capabilities of the Joint Force.
