The KH-11 replaced the KH-9 film return satellite, among others, the last of which was lost in a liftoff explosion in 1986. All KH-11 satellites are in either of two standard planes in Sun-synchronous orbits. As shadows help to discern ground features, satellites in a standard plane east of a noon/midnight orbit observe the ground at local ...
Details of USA-245's mission are classified by the US military, however numerous independent analysts identified it as a KH-11 before launch, and amateur satellite watchers have since observed it in the orbit used by such satellites. [3] [4] KH-11 satellites are used to provide high-resolution optical and infrared imagery for US intelligence ...

The KH-11 Kennen (or perhaps the now cancelled Future Imagery Architecture) telescopes may be a three-mirror anastigmat, since the spare telescopes given to NASA by the National Reconnaissance Office are of this form. The Extremely Large Telescope will be a three-mirror anastigmat design, with two additional flat fold mirrors.

An unnamed space analyst stated that the instruments may be a part of the KH-11 Kennen line of satellites which have been launched since 1976, but which have now been largely superseded by newer telescopes with wider fields of view than the KH-11. The analyst stated, however, that the telescopes have "state-of-the-art optics" despite their ...
