Galaxy 18 replaced Galaxy 10R near the end of its design life.
The DirecTV satellite fleet is a group of communications satellites located at various geostationary orbits that DirecTV uses for their satellite television service and HughesNet internet service. The "DirecTV" prefix in their names has been changed to "T".
Galaxy 10R was an American communications satellite which was operated by PanAmSat, and later Intelsat. It was constructed by Hughes and is based on the HS-601HP satellite bus. Launch occurred on 25 January 2000, at 01:04. The launch was contracted by Arianespace, and used an Ariane 4 42L-3 carrier rocket flying from ELA-2 at the Guiana Space Centre.
Galaxy 11 is an American geostationary communications satellite which is operated by Intelsat. It is located in geostationary orbit at a longitude of 32.8 degrees east, where it serves as a backup to the Intelsat 802 spacecraft. It was originally operated at 99° West and later spent most of its operational life at 91° West, from where it was used to provide communications services to Brazil and North America.
Galaxy 15 is an American telecommunications satellite which is owned by Intelsat. It was launched for and originally operated by PanAmSat, and was subsequently transferred to Intelsat when the two companies merged in 2006. It was originally positioned in geostationary orbit at a longitude of 133° West, from where it was used to provide communication services to North America.
AsiaSat 6 / Thaicom 7 is a geostationary communications satellite which is operated by the Asia Satellite Telecommunications Company (AsiaSat) and was launched into orbit on 7 September 2014. The satellite project was developed in cooperation between satellite operators AsiaSat and Thaicom. AsiaSat owns half of the satellite's 28 transponders which are marketed as AsiaSat 6. The other half of the satellite is owned by Thaicom and is marketed as Thaicom 7. AsiaSat's part of the satellite is operated under license of the China (PRC), whereas Thaicom's part is operated under license of Thailand.
Horizons-1, also known as Galaxy 13, is a geostationary communications satellite operated by Intelsat and SKY Perfect JSAT (JSAT) which was designed and manufactured by Boeing on the BSS-601 platform.
