DirecTV-2 having reached the end of its useful life span, on April 16, 2007, the FCC granted DirecTV's request to conduct operations to deorbit the satellite, it was subsequently removed from service in May 2007.
DirecTV-3 was removed from service in Oct 2002 and sent to a storage orbit as an on-orbit backup. It returned to service in 2003 having been leased to Telesat, which used the satellite as backup for its troubled Nimiq-2 at 82 degrees West under the designation Nimiq-2i. In 2004 the satellite was moved to back up Nimiq-1 and is now operated under the name Nimiq-3.
DirecTV-6 went out of service August 15, 2006 and sent to a graveyard orbit
