BYEMAN codenamed LANYARD, the KH-6 was the unsuccessful first attempt to develop and deploy a very high-resolution optical reconnaissance satellite by the United States National Reconnaissance Office.<ref>Template:Cite web</ref> Launches and launch attempts spanned the period from March to July 1963. The project was quickly put together to get imagery of a site near Leningrad suspected of having anti-ballistic missiles.<ref name=":1">Template:Cite web</ref>
The satellite carried Itek's "E-5" camera developed for the SAMOS program, which had been cancelled. The camera had a focal length of Template:Cvt and could discern objects on the ground Template:Cvt in size. The ground swath of the camera was Template:Cvt. The satellite weighed Template:Cvt, and had a single re-entry vehicle in which exposed film was returned to earth for a mid-air<ref name="FAS">Federation of American Scientists FASorg: KH-6 Template:Webarchive</ref> aircraft recovery.
The KH-6 was manufactured by Lockheed Martin and launched from Vandenberg Air Force Base on Thor-Agena D launch vehicles.<ref>Template:Cite web</ref>
Launches
KH-6 8001 was launched from Vandenberg AFB aboard a Thor-Agena D launch vehicle (Thor 360)<ref name=":0">Template:Cite web</ref> at 00:00:00 GMT on 18 March 1963. It was the first of three KH-6 LANYARD launches. This mission was a failure because the Agena guidance system failed.<ref>Template:Cite web</ref><ref name=":1" />
KH-6 8002 was launched from Vandenberg AFB aboard a Thor-Agena D rocket (Thor 364)<ref name=":0" /> at 22:34:00 GMT on 18 May 1963. This was the second launch KH-6 LANYARD satellite. This spacecraft achieved orbit but the Agena rocket failed in flight and no film data were returned.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
KH-6 8003 was launched from Vandenberg AFB aboard a Thor-Agena D rocket (Thor 382)<ref name=":0" /> at 00:00:00 GMT on 31 July 1963. This was the third and final KH-6 (LANYARD) mission that was designed to provide very high-resolution photos (61 cm), but the best resolution achieved was 183 cm, the same as KH-4B, so LANYARD was discontinued after this 3rd flight in 1963. The camera failed after 32 hours.<ref>Template:Cite web</ref> The mission was deemed a success but the image quality was poor.<ref>Template:Cite web</ref> The film canister contained over 2,250 feet of film with 910 photographic frames.<ref name="FAS" />
