Description: The attack on the Sui-ho Dam was the collective name for a series of air attacks by United Nations Command air forces on 13 hydroelectric generating facilities in North Korea that took place June 23 and June 24, 1952, during the Korean War. The attack was intended to apply political pressure at the stalled truce negotiations at Panmunjeom.
The attacks were conducted jointly by fighters and fighter-bombers of the United States Air Force, United States Navy, United States Marine Corps, and South African Air Force, the first time in 21 months that the separate air arms had worked together on a massive scale. It was followed within two weeks by another series of joint attacks on the capital city of Pyongyang.
The attacks succeeded in permanently destroying 90% of the facilities struck and completely knocked out power in North Korea for two weeks, as well as reducing available power to northeast China by 23%. North Korea, however, built new facilities but did not restore its previous capacity until after the armistice in 1953. Their effect on the truce talks was also nil, as highly-publicized repercussions in both the UK and the United States Congress undermined their impact. They were repeated on a limited scale in the spring of 1953 and may have played a role in bringing about the eventual truce.
