USS Pueblo (AGER-2) is an American ELINT and SIGINT Banner-class technical research ship (Navy intelligence) which was boarded and captured by North Korean forces on 23 January 1968, in what is known as the Pueblo incident or alternatively as the Pueblo crisis or the Pueblo affair. The declassified SIGAD for the National Security Agency (NSA) Direct Support Unit (DSU) from the Naval Security Group (NSG) on the USS Pueblo during the patrol involved in the incident was USN-467Y. The capture, less than a week after President Lyndon B. Johnson's State of the Union address and only a week before the start of the Tet Offensive, and subsequent 11-month prisoner drama were major incidents in the Cold War.
