SpaceX Falcon 9 launches classified USSF-432 mission from Vandenberg

Space.com and Spaceflight Now report a Falcon 9 lifted off from Vandenberg on Nov. 6 with a classified U.S. Space Force payload, with observers linking it to Starshield satellites.

A SpaceX Falcon 9 rocket lifted off from Vandenberg Space Force Base in California on Nov. 6 with a classified payload for the U.S. Space Force, both Space.com and Spaceflight Now reported1,2.

Liftoff was at 4:48 p.m. PST (7:48 p.m. EST, 0048 UTC on Nov. 7) from pad 4E, Spaceflight Now said, on a south-easterly path from the central California coast2. Space.com described a sunset launch over the Pacific1.

The mission is designated USSF-4321,2. Spaceflight Now said public documents also identify it as R-4, following USSF-366 (R-1) on Aug. 16, USSF-153 (R-2) on Sept. 10 and USSF-385 (R-3) on Sept. 262.

Neither SpaceX nor the Space Force provided much information about the payload, Space.com reported, and SpaceX ended its webcast about 10 minutes into the flight after the first stage landed1. Spaceflight Now said the Space Force has declined to discuss the missions and that neither company nor the service has confirmed satellite deployment on earlier flights in the series2.

The first-stage booster, designated 1095, made its eighth flight and landed on the droneship Of Course I Still Love You in the Pacific, both outlets reported1,2. Spaceflight Now said the booster's previous flights were from Florida and that it moved west after a GPS 3-8 launch in April2.

Outside observers have linked the flight to low Earth orbit satellites for the Space Force's Space Based Sensing and Targeting program built on SpaceX's Starshield bus, a government counterpart to Starlink1,2. Space.com cited NextSpaceflight.com saying drop zones matched earlier Starlink Group 15 launches1. Spaceflight Now said each prior R launch placed 23 satellites in orbit according to catalog entries and cited tracker Jonathan McDowell on the sensing-and-targeting link2.

Spaceflight Now said the launch had been scheduled for Nov. 1 and slipped first because of the Starlink 15-18 mission, then for reasons that were not disclosed2. Space.com counted USSF-432 as SpaceX's 125th launch of 2026, the 119th Falcon 9 flight this year and the 14th national-security Falcon 9 mission of 20261.

What the satellites do, how many were aboard USSF-432, and whether they reached their intended orbits were not confirmed in the two reports1,2.
