SpaceX to launch classified USSF-153 mission for US Space Force on Sept. 10

SpaceX is scheduled to lift off today, September 10, carrying the classified USSF‑153 mission on behalf of the United States Space Force. The launch will take place from Space Launch Complex 40 at Cape Canaveral Space Force Station, using a Falcon 9 booster that has previously flown on multiple government and commercial missions. The payload, identified only as USSF‑153, is part of the Space Force’s ongoing effort to expand its on‑orbit capabilities, though specific objectives and payload details remain undisclosed due to the mission’s classified status.

The flight will be streamed live on SpaceX’s official website and the company’s social media channels, allowing the public to observe the launch sequence in real time. Officials from both SpaceX and the Space Force have confirmed that the mission follows a standard launch profile, with the first stage expected to return to a designated landing zone after separation. Completion of the USSF‑153 mission will add to the growing inventory of classified assets supporting national security operations in space.
