SES-1 is a geostationary communications satellite which is operated by SES World Skies. It was originally ordered by SES Americom as a ground spare for AMC-5R however in April 2008 a decision was made to launch it and it was named AMC-1R. It was subsequently renamed AMC-4R and finally SES-1 after SES Americom merged with SES New Skies to form SES World Skies. It was the third World Skies satellite to be launched following the merger but the first to carry the new SES designation.
