While not officially confirmed by the NRO or the Government of the United States prior to 2008, there was widespread evidence pointing to its existence, including one NASA website.
[5] The launch of NROL-41 (USA 215) in September 2010 has all orbital characteristics of a radar remote sensing platform (see FIA) and could be the first of a Lacrosse follow-up program.
These orbital inclinations of 68° and 57°, combined with their altitude give the satellites a complete view of the Earth's surface, including the north and south poles.
(Amateur observers call this rapid fade its "disappearing trick", although it appears to be an accidental phenomenon due to the design of the craft and not a deliberate stealth feature.)
The story of the 1994 Andy Sidaris film The Dallas Connection involves a series of codes necessary to control a Lacrosse reconnaissance satellite.
