Which US Navy ship was attacked and captured by North Korean forces on the 23rd of January, 1968?

USS Pueblo (AGER-2) is a Banner-class environmental research ship, attached to Navy intelligence as a spy ship, which was attacked and captured by North Korean forces on 23 January 1968, in what is known today as the "Pueblo incident" or alternatively, as the "Pueblo crisis".

The taking of Pueblo and the abuse and torture of its crew during the subsequent 11-month prisoner drama became a major Cold War incident, raising tensions between the western democracies and the Union of Soviet Socialist Republics and People's Republic of China.

North Korea stated that Pueblo deliberately entered their territorial waters 7.6 miles away from Ryo Island, and that the logbook shows that they intruded several times. However, the United States maintains that the vessel was in international waters at the time of the incident and that any purported evidence supplied by North Korea to support its statements was fabricated.

Pueblo, still held by North Korea today, officially remains a commissioned vessel of the United States Navy. Since early 2013, the ship has been moored along the Botong River in Pyongyang, and used there as a museum ship at the Pyongyang Victorious War Museum. Pueblo is the only ship of the U.S. Navy still on the commissioned roster currently being held captive.
