On January 23, 1968, North Korean patrol boats supported by two Mikoyan-Gurevich MiG-21 fighters captured the USS Pueblo northeast of the North Korean island of Ung-do.[1] The seizure of the Pueblo led to President Lyndon Johnson ordering a show of force with a massive deployment of U.S. air and navy assets to Korea. The airlift and deployment of 200+ aircraft was code named Operation Combat Fox[2] while the deployment of six aircraft carriers plus support vessels was code named Operation Formation Star.[3] The operations were supported by the partial mobilization of reservists for the first time since the Cuban Missile Crisis.[3] CIA A-12 Oxcart reconnaissance overflights over North Korea were used to monitor a feared retaliatory mobilization of North Korean forces and when these flights revealed no mobilization or large scale deployments by North Korean forces, Operation Combat Fox forces were stood down.[4]
