History

In 1995, a Los Angeles Times article reported that the 8X program was intended as "a major upgrade to the KH-12", with a mass of as much as 20 tons, which would be used for detailed imaging with a wide field of view. The cost of the program was a subject of disagreement from some within the military at the time.<ref name="LA_Times_Risen_Vartabedian">Template:Cite news</ref><ref name="web_post_8x">Template:Cite web</ref> By 1998, the program had been renamed Enhanced Imaging System.<ref name="EIS"/> The Future Imagery Architecture program, which was intended to replace the Lacrosse and Improved Crystal satellites, was developed alongside EIS.<ref name="EIS"/>
