According to Wikipedia: "The KH-11 KENNAN (KENNEN according to other sources), renamed CRYSTAL in 1982 and according to recently leaked NRO budget documentation currently going by the codename of Evolved Enhanced CRYSTAL (EEC) (but also referenced by the codenames 1010, and "Key Hole"), is a type of reconnaissance satellite first launched by the American National Reconnaissance Office in December 1976. Manufactured by Lockheed in Sunnyvale, California, the KH-11 was the first American spy satellite to use electro-optical digital imaging, and create a real-time optical observation capability."
