Definition
USS Pueblo (AGER‑2) was a United States Navy auxiliary general environmental research (AGER) vessel, best known for being captured by North Korean forces on 23 January 1968 during a covert intelligence‑gathering mission.
Overview
Commissioned on 12 June 1966, Pueblo served as a “technical research ship” ostensibly conducting environmental studies while actually collecting signals intelligence (SIGINT) in the Pacific and East Asian waters. On 23 January 1968 the ship entered North Korean territorial waters near the mouth of the Yalu River. North Korean patrol boats seized the vessel, detained its 82‑person crew, and removed it from U.S. control. The incident, commonly referred to as the “Pueblo incident,” heightened Cold‑War tensions and resulted in prolonged diplomatic negotiations. The crew was released after 11 months of captivity in December 1968, but the ship remains in North Korean possession, displayed as a museum ship at Pyongyang’s Victorious Fatherland Liberation Museum.
Etymology/Origin
The ship was named after Pueblo, a city in Colorado, following the U.S. Navy tradition of naming auxiliary vessels after U.S. towns and cities. The hull classification “AGER” denotes “auxiliary general environmental research,” a cover designation used for vessels conducting covert intelligence missions.
