Enhanced Imaging System

Enhanced Imaging System (EIS), officially referred to as "Enhanced Imagery System",[1][2] previously known as 8X, and sometimes unofficially known as Misty 2 and KH-13,[3] is an American reconnaissance satellite program. A derivative of the Improved Crystal satellites,[4] EIS replaced Misty, and was intended to provide more coverage and dwell time than previous reconnaissance satellites;[5] like Misty, it has stealth capabilities.[6] Only one EIS satellite has been launched; USA-144, which was placed into orbit by a Titan IVB rocket on 22 May 1999.[7][8]
