Operation Formation Star was the code name for the emergency re-deployment of U.S. Seventh Fleet warships to the Sea of Japan off the eastern coast of North Korea following that country's seizure of the USS Pueblo (AGER-2) in international waters on 23 January 1968. Although a wide range of military options were considered, the Johnson Administration elected to resolve the Pueblo crisis diplomatically, with Operation Formation Star helping to provide a "measured show of force" during the Pueblo crisis.
