Later KH-11 satellites have been referred to by outside observers as KH-11B or KH-12, and by the names "Advanced KENNEN", "Improved Crystal" and "Ikon". Official budget documents refer to the latest generation of electro-optical satellites as Evolved Enhanced CRYSTAL System.[8] The Key Hole series was officially discontinued in favor of a random numbering scheme after repeated public references to KH-7 GAMBIT, KH-8 GAMBIT 3, KH-9 HEXAGON, and KH-11 KENNEN satellites.[9]
The capabilities of the KH-11 are highly classified, as are the images they produce. The satellites are believed to have been the source of some imagery of the Soviet Union and China made public in 1997;[citation needed] images of Sudan and Afghanistan made public in 1998 related to the response to the 1998 U.S. embassy bombings;[10] and a 2019 photo, provided by then President Donald Trump,[11] of a failed Iranian rocket launch.
