The Museum displays the history of the attack of the U.S.S. Pueblo. Following the war between the two Koreas in the 1950s, the United States continued to support South Korea. In an effort to gather intelligence about North Korea's intentions, the U.S. Navy began operational cruises with AGER ships outfitted with reconnaissance equipment. On January 23, 1968, while in international waters off the Korean coast, the North Koreans attacked the Pueblo. One man was killed while destroying cryptologic materials and three men were wounded. The 82 crewmen were held for 11 months before being released. The ship remains in North Korea to this day and it represented the largest single loss of such sensitive material. It compromised a wide range of cryptologic and classified documents and equipment.
