===Final missions over North Korea===
In 1968, three missions were flown over North Korea. The first mission occurred during a very tense period following seizure of the Navy intelligence ship [[USS Pueblo (AGER-2)|''Pueblo'']] on 23 January. The aim was to discover whether the North Koreans were preparing any large scale hostile move following this incident and to actually find where the ''Pueblo'' was hidden. The ship was found anchored in an inlet in [[Wonsan|Wonsan Bay]] attended by two North Korean patrol boats and guarded by three [[Komar class missile boat]]s.<ref>{{cite web|title=Preliminary Assessment of Black Shield Mission 6847 Over North Korea|url=http://www.foia.cia.gov/sites/default/files/document_conversions/89801/DOC_0001474986.pdf|publisher=Central Intelligence Agency Document Number: 0001474986|access-date=4 April 2014|archive-date=17 July 2013|archive-url=https://web.archive.org/web/20130717095625/http://www.foia.cia.gov/sites/default/files/document_conversions/89801/DOC_0001474986.pdf|url-status=dead}}</ref> Chinese tracking of the flight was apparent, but no missiles were fired at the Oxcart.{{sfn|McIninch|1996}}

The second mission on 19 February 1968, was also the first two-pass mission over North Korea. The Oxcart vehicle photographed 84 primary targets plus 89 bonus targets. Scattered clouds covered 20 percent of the area, concealing the area in which the USS ''Pueblo'' was photographed on the previous mission. One new SA-2 site was identified near Wonsan.<ref>{{cite web |title=Black Shield Reconnaissance Missions 1 January – 31 March 1968 |url=http://www.foia.cia.gov/sites/default/files/document_conversions/89801/DOC_0001472531.pdf |publisher=Central Intelligence Agency Document Number 0001472531 Page 14 |access-date=5 April 2014 |archive-date=11 February 2013 |archive-url=https://web.archive.org/web/20130211185411/http://www.foia.cia.gov/sites/default/files/document_conversions/89801/DOC_0001472531.pdf |url-status=dead }}</ref>
