With the delivery of the seventh spacecraft in the Intelsat-IX series—Intelsat 907—in early 2003, SS/L has built 31 fixed-satellite services spacecraft for Intelsat, nearly half of its historical fleet, and significantly more than any other manufacturer.

The seven SS/L-built, improved, high-capacity Intelsat-IX communications satellites began service in 2001, with Intelsat 907 launched in 2003. They replace the Intelsat-VI series spacecraft and are on orbit to provide enhanced services for customers of this global satellite services provider.

The Intelsat-IX spacecraft are multi-frequency communications satellites that provide voice, video, data transmission, and distribution to virtually any location in the regions around the Atlantic and Indian Oceans. These spacecraft are among the world's largest and most powerful commercial communications satellites.

Intelsat-IX features an improved satellite switched-time division, multiple-access subsystem within its payload to achieve more efficient traffic loading on a number of its transponders.

SS/L delivered nine Intelsat-VII/VIIA spacecraft beginning in 1993. Like Intelsat-IX, Intelsat-VII spacecraft are multi-frequency communications satellites providing voice, video, data transmission, and distribution services to any location in the regions around the Atlantic, Indian, and Pacific oceans. The powerful Intelsat-VIIA satellites offer increased coverage and flexibility with 19 independent, interconnectable coverage areas.

The Intelsat-V series pioneered global satellite telecommunications. They were the first Intelsat hybrid satellites, capable of providing service in both C- and Ku-bands, and the first to reuse the frequency bands by spatial separation and polarization diversity, permitting some frequencies to be used four times.
