SpaceX Launches Classified USSF-481 Mission for US Space Force

Stateline MEDIA Newsroom•October 15, 2026•3 min read

SpaceX launched the classified USSF-481 mission from Vandenberg Space Force Base, California, on Thursday (15/10/2026). Falcon 9 booster B1081 flew its 28th flight carrying a classified payload believed to be military satellites bound for polar orbit. The mission is part of the Golden Dome missile defence programme and marks California's 70th rocket launch of 2026.

Key Facts

SpaceX launched the classified USSF-481 mission from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base, California, on Thursday (15/10/2026); the four-hour launch window opened at 4:44 PM Pacific Time, or Friday (16/10/2026) at 6:44 AM Western Indonesia Time.
The mission's payload is classified, but space media report it likely carries a batch of military satellites destined for polar low Earth orbit (LEO).
The Falcon 9 booster B1081 flew for its 28th flight; the first stage was planned to land on the 'Of Course I Still Love You' droneship in the Pacific Ocean.
The mission is part of the Pentagon's $1.6 billion programme to build a missile-tracking satellite network in polar orbit, at the centre of the Golden Dome missile defence plan.
The launch was the 70th rocket launch in California in 2026 — one more liftoff to tie the 2025 record of 71 launches; the record-breaking mission is scheduled for 24 October.

SpaceX Launches Classified USSF-481 Mission from Vandenberg

SpaceX launched the classified USSF-481 mission from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base, California, on Thursday (15/10/2026). The four-hour launch window opened at 4:44 PM Pacific Time — Friday (16/10/2026) at 6:44 AM Western Indonesia Time.

The mission is a national security contract for the U.S. Space Force. The payload is classified, but space media report it likely carries a batch of military satellites that will operate in polar low Earth orbit (LEO).

The 70-metre Falcon 9 rocket used in the mission was powered by booster B1081 — flying for its 28th flight. The veteran booster previously launched, among others, the Crew-7 crewed mission, the CRS-29 cargo mission, and 16 Starlink missions. Following stage separation, the first stage was planned to land on the 'Of Course I Still Love You' droneship in the Pacific Ocean.

Part of the Golden Dome Missile Defence Programme

According to Tech Times, USSF-481 is part of the Pentagon's $1.6 billion programme to build a missile-tracking satellite network in polar orbit. The mission advances the Proliferated Warfighter Space Architecture — the U.S. Department of Defense initiative to deploy hundreds of linked military satellites.

The architecture sits at the centre of the Trump administration's Golden Dome missile defence plan. Polar LEO at altitudes of 750-1,200 kilometres allows satellites to sweep every point on Earth's surface twice daily — a geometry specifically designed for missile warning and infrared sensing of ground-based launch signatures.

SLC-4E at Vandenberg is the only U.S. launch pad that permits southward or polar departure azimuths without overflying populated land. Every Falcon 9 national security mission requiring polar orbit launches from there — and USSF-481 is no exception.

California's 70th Rocket Launch of 2026

The launch was the 70th rocket launch in California in 2026, bringing the state within one liftoff of tying the record of 71 launches in a year set in 2025. If the schedule holds, the record-breaking mission is on tap for 24 October.

The U.S. National Weather Service forecast sunny and mostly clear skies during the launch window in Santa Barbara County. SpaceX provided a live webcast of the mission starting about ten minutes before liftoff, though there was no video from the second stage or fairing deployment after separation due to the mission's classified nature.
