SpaceX is set to launch USSF-385, a classified U.S. Space Force mission, from Vandenberg's Space Launch Complex 4-East, with a three-hour window opening at 5:56 a.m. Pacific on Saturday September 26, 2026. Neither the Space Force nor SpaceX has disclosed the payload, but launch trackers say it fits the pattern of a National Reconnaissance Office-linked Starshield deployment — the militarised sibling of Starlink.
What Is Flying
The mission uses Falcon 9 booster B1100 on its tenth flight, following NROL-95 and eight Starlink assignments. The first stage is targeting a Pacific droneship landing on Of Course I Still Love You. USSF-385 slots into a cluster of West-Coast Space Force missions — USSF-366 in August and USSF-153 on September 10 each seeded 23 Starshield satellites — that are quietly building a proliferated intelligence constellation designed to be resilient against Chinese and Russian anti-satellite weapons.
Why It Matters
The Pentagon has openly reframed low-Earth orbit as a warfighting domain. In practice that has meant contracting SpaceX to fly a Starshield fleet estimated at more than 200 spacecraft, providing tasked imagery and signals collection in place of a handful of exquisite spy satellites. The design bet is redundancy: enough small satellites that no adversary weapon can meaningfully degrade the constellation.
Cadence And Backups
If weather forces a scrub, SpaceX has a backup window at 5:49 a.m. Pacific on Sunday. The launch keeps SpaceX on pace to exceed 200 orbital flights in 2026 — a tempo unmatched by any other launch provider and one that has made national-security space unusually dependent on a single vendor. It also follows Google's Project Suncatcher plans to orbit TPUs on a SpaceX Transporter next week and the recent SpaceX 700th Falcon flight.
What Is Still Redacted
The exact orbit, satellite count and specific customer agency remain classified. Analysts note that USSF-259 on September 17 carried roughly 17 satellites into a different orbit, suggesting USSF-385 may be a similar mixed-orbit Starshield cluster rather than another 23-satellite plane. SpaceX confirms only that live coverage begins about 10 minutes before liftoff on its channels.
