Mission Details

KH-11 17 (Crystal 17) (USA-290) (NROL-71)

The KH-11 series, known as Kennen and Crystal, are American spy satellites utilizing electro-optical digital imaging for real-time observation, supplanting earlier film-return satellites. Manufactured by Lockheed, they likely incorporate a 2.4 m prime mirror, offering a theoretical 15 cm ground resolution. First launched by the American National Reconnaissance Office in December 1976, the KH-11 KENNEN was the inaugural American spy satellite to employ electro-optical digital imaging technology, enabling real-time optical observations.
