This is a list of satellites operated by SES S.A.

The AMC fleet was originally operated by GE Americom, acquired by SES Global in 2001. Americom was also operating the older Satcom fleet, whose last operating spacecraft were fully retired in the early 2000s.

There are 11 fully-operational Astra satellites and another 2 as backup/reserve, the majority in four orbital locations - Astra 19.2°E, Astra 28.2°E, Astra 23.5°E, Astra 5°E. Astra's principle of "co-location" (several satellites are maintained close to each other, all within a cube with a size of 150 km (93 mi).^[15]) increases flexibility and redundancy.

This fleet came from the acquisition of New Skies Satellites in 2005, which itself had inherited 5 satellites from Intelsat in 1998.

The O3b fleet was initially owned and operated by O3b Networks, which became a wholly owned subsidiary of SES S.A. in 2016^[123] Orbiting in Medium Earth orbit (MEO), the first generation satellites are sometimes referred to as "O3b MEO" to more clearly distinguish them from the forthcoming second generation O3b mPOWER constellation (to launch 2022–2024, and start service in Q3 2023).^{[124][125][126][127]}.

SES also manages some transponders on a few third-party satellites under joint operating agreements.
