U.S. Space Force’s Space Systems Command and Japan launch First Bilateral Space Effort

KAGOSHIMA, Japan  –  

A U.S. space domain awareness payload hosted on Japan's Quasi-Zenith Satellite 6 (QZS-6) successfully launched on a Japanese H-3 launch vehicle from the Yoshinobu Launch Complex at the Japan Aerospace Exploration Agency’s (JAXA) Tanegashima Space Center (TNSC) in Japan on February 2, 2025. This is the first bilateral U.S. Japan cooperative space effort focused on national security, and the first of two launches as part of the JAXA Quasi-Zenith Satellite System Hosted Payload (QZSS-HP) program.

The satellite will be operated by Space Operations Command’s (SpOC) Mission Delta 2 (MD 2), which conducts Space Domain Awareness operations to identify, characterize, and exploit opportunities and mitigate vulnerabilities in the national security space terrain on behalf of the U.S. Space Force (USSF) and U.S. Space Command. The satellite will deliver near real time data to the Space Surveillance Network bolstering the U.S. Department of Defense (DoD) understanding of the Geosynchronous Orbit regime above the Indo-Pacific region.

“This launch is a historic milestone for the U.S.-Japan alliance,” said USSF Col. Bryon McClain, program executive officer for Space Systems Command’s (SSC) Space Domain Awareness and Combat Power. “In an increasingly contested space domain, Japan's contribution to the U.S. DoD’s deterrence strategy has been, and will continue to be, key to INDOPACOM awareness and operations. We look forward to continuing to collaborate with Japan on space modernization, data sharing, satellite communications, and more.”

"Congratulations to both nations on this achievement. Mission Delta 2 is honored to operate these payloads as they get on orbit on behalf of the USSF. These sensors will support the fusion of space- and ground-based Space Domain Awareness to further reinforce all-domain collective defense with allies and partners in the Indo-Pacific,” explained USSF Col. Raj Agrawal, commander or SpOC’s Mission Delta 2.
