SpaceX successfully launched GPS III SV10, the tenth and final satellite in the U.S. Space Force's advanced GPS III constellation, on April 21, 2026, from Cape Canaveral Space Force Station in Florida. This navigation satellite represents the completion of a modernized GPS architecture designed to provide enhanced positioning, navigation, and timing capabilities to military and civilian users worldwide. The GPS III satellites feature improved accuracy, anti-jamming capabilities, and longer operational lifespans compared to their predecessors.

The mission flew aboard a Falcon 9 Block 5 rocket, utilizing first-stage booster B1095 on its seventh flight. The vehicle had previously launched six batches of Starlink satellites, demonstrating SpaceX's reusability approach to spaceflight operations. The payload fairing also showcased component reuse, with one half flying for the second time and the other for the third time.

The launch achieved successful insertion of the GPS III SV10 satellite into orbit, marking the completion of the ten-mission GPS III series. This mission represented the fourth consecutive GPS launch on an accelerated schedule, underscoring Lockheed Martin's rapid delivery of on-orbit capabilities to support U.S. military operations. With GPS III SV10 now deployed, the Space Force has established its next-generation GPS constellation while paving the way for future GPS IIIF spacecraft development.
