In early 1968, the seizure of the USS Pueblo by North Korea triggered a major international crisis at a time when the United States was already deeply involved in the Vietnam War. The U.S. maintained that the ship had been operating in international waters, while North Korea insisted it had violated its territorial boundaries. With American forces heavily committed in Southeast Asia, President Lyndon B. Johnson chose not to escalate the situation into open conflict on the Korean Peninsula.
The Pueblo’s 83 crew members were held captive for nearly eleven months under harsh conditions. They endured beatings, limited food, and forced confessions, yet still found subtle ways to resist. In staged propaganda photos, some sailors discreetly extended their middle fingers, telling their captors it was a “Hawaiian good luck sign.” Once the true meaning was uncovered, they faced severe punishment.
On December 23, 1968, the crew was finally released at the Bridge of No Return in the Korean Demilitarized Zone. Though physically weakened, they returned home with their morale intact. The USS Pueblo itself was never returned and remains in Pyongyang, where it is displayed as a propaganda exhibit—still holding the distinction of being the only commissioned U.S. Navy ship in the custody of a foreign government.
USS Pueblo (AGER-2) prior to becoming a spy ship
Constructed in 1944 as the Banner-class cargo ship FP-344/FS-344 for the U.S. Army, the vessel spent her early years away from active combat. In April 1945, responsibility for the ship transferred to the U.S. Coast Guard, which used her to train civilians preparing to enter Army service during the closing months of World War II. She continued in this relatively quiet training capacity until she was decommissioned in 1954, after which she largely disappeared from public view.
More than ten years later, the ship was brought back into active service and extensively modernized. After being recommissioned as USS Pueblo (AKL-44), she initially served as a light cargo vessel before receiving a new classification as AGER-2 and the official designation of an “environmental research vessel.”
Despite that seemingly routine title, the ship’s true purpose was far more secretive. Her conversion transformed USS Pueblo into a signals intelligence platform fitted with communications interception and surveillance equipment. While outwardly conducting research, she was assigned to gather electronic intelligence on behalf of the Office of Naval Intelligence and the National Security Agency, supporting covert Cold War operations during a time of escalating tensions involving North Korea and the wider Soviet bloc.
USS Pueblo (AGER-2) is deployed to North Korea
By 1967, the USS Pueblo had completed shakedown training and was prepared for its first espionage mission. On January 5, 1968, the ship set sail with the goal of gathering intelligence on both North Korea and the Soviet Navy. Eleven days later, the Pueblo reached the 42nd parallel, ready to patrol the North Korean coastline while staying at least 13 nautical miles away from shore.
On January 23, 1968, North Korea launched an attack on the Pueblo. The spy ship was spotted by a submarine chaser, which issued an ultimatum: surrender or face fire. Although the Pueblo tried to flee, its slower speed made it impossible to evade the threat.
The submarine chaser was soon joined by four torpedo boats, another chaser, and two Mikoyan-Gurevich MiG-21 aircraft. Armed with only a few handguns and two M2 Browning machine guns, the Pueblo and her crew were severely outgunned. Despite this, they put up resistance for as long as possible to prevent the North Koreans from boarding.
North Korea captures the USS Pueblo (AGER-2)
As the USS Pueblo neared the North Korean port of Wonsan, the crew rushed to destroy classified documents and intelligence records. The process forced the ship to slow down, making it an easier target for the approaching enemy.
North Korean patrol boats soon attacked with machine-gun fire and a 57 mm cannon. During the assault, crewman Duane Hodges was killed, while two others, including U.S. Marine Sgt. Bob Chicca, were wounded. North Korean forces then boarded and captured the ship, blindfolding the crew and tying their hands.
After being taken ashore, the crew members were subjected to harsh treatment and repeated physical abuse while in North Korean captivity.
American sailors were held captive for months
During the attack on the USS Pueblo, the crew managed to establish radio contact with US forces in South Korea. Chicca later recounted, “The last conversations we got over the radio were that help was on the way, and it obviously wasn’t. I could not believe that we would be abandoned out there the way we were.”
Despite promises of assistance from a squadron of McDonnell Douglas F-4 Phantom IIs, they never arrived. they never arrived. As a result, the 82 crew members were captured and endured 11 months of torture by their captors. Chicca reflected, “We were an experiment that was deemed, I don’t know whether it would be a failure, but it certainly didn’t work.”
After enduring months of psychological torment, the North Koreans eventually forced a confession from commanding officer Lloyd Bucher. He admitted to intruding on their territorial waters and committing hostile acts, but only under the threat that each crew member would be killed one by one if he refused.
Signing the three A’s document
At the time of the USS Pueblo’s capture, the United States was deeply involved in the Vietnam War. Concerned that tensions with North Korea could escalate, American officials pursued a diplomatic approach to address the crisis. After nearly a year, both nations reached an agreement that allowed for the safe return of the Pueblo’s crew.
On December 23, 1968, US Army Maj. Gilbert Woodward signed a document known as the “three A’s agreement,” drafted by North Korean authorities. This agreement required the United States to acknowledge wrongdoing, apologize, and pledge to prevent similar incidents in the future.
Following this, the crew members were released and returned to the United States, while the Pueblo remained in North Korean possession. Initially displayed in Wonsan and Hŭngnam, the vessel was eventually moved to the Victorious Fatherland Liberation War Museum in Pyongyang.
USS Pueblo (AGER-2) is still held captive
When North Korean forces took control of the USS Pueblo, they also captured 10 encryption devices and thousands of highly classified documents—marking one of the most damaging intelligence losses of the Cold War. The trove of secret material offered North Korea and its allies, including the Soviet Union, a rare window into U.S. surveillance techniques and communication codes.
Remarkably, the Pueblo is still listed as an active commissioned vessel by the U.S. Navy, despite being held in enemy territory since 1968. Now docked in Pyongyang, the ship has been transformed into a museum exhibit and a powerful symbol of North Korean propaganda. It undergoes regular maintenance and has even received commemorative paint jobs to coincide with national observances like the anniversary of the Korean War.
In response to North Korea’s ongoing defiance and a renewed U.S. designation as a state sponsor of terrorism in 2017, surviving crew members and the families of deceased sailors filed a lawsuit under the Foreign Sovereign Immunities Act. In 2021, a U.S. court awarded them $2.3 billion in damages. Still, collecting on that judgment remains a long shot, as there are no straightforward financial links between the United States and North Korea.
