Summary

[edit]
Description
English: The Lanzhou Gaseous Diffusion Plant, as photographed on May 10, 1966, by a KH-7/GAMBIT satellite during Mission 4028. Early 1960s U.S. intelligence analyses significantly underestimated Lanzhou's ability to produce the highly enriched uranium needed for China's first bomb. Derived from Dwayne A. Day, John M. Lodgson, and Brain Latell (eds.), Eye in the Sky: The Story of the Corona Spy Satellites (Washington, D.C.: Smithsonian, 1998), pp. 231-233.
