Space Operations Squadron (宇宙作戦隊, Uchū Sakusentai) is a Japan Air Self-Defense Force unit based at Fuchu Air Base in Fuchu, Tokyo.[2] It is responsible for the JASDF's space domain awareness capability, integrating surveillance data from a sensor near Sanyo-Onoda in Yamaguchi Prefecture, along with data supplied by JAXA and the United States Space Force. The unit also conducts satellite navigation and satellite communications for other military units.[3][4][5]


The SOS was established in May 18, 2020 in a ceremony held by the Japanese Ministry of Defense with 20 JASDF personnel.[6] A JASDF spokesman said that the SOS will have 100 personnel in the future.[6]

The squadron will be fully operational in 2023.[7]
