At Clark's direction, FEAF prepared two attack plans on the system, one of which included bombing the Sui-ho Dam while the other did not. The three systems in South Hamgyong were targeted, while two smaller systems—one near the border with the Soviet Union and the other immediately behind the battleline—were excluded. The plans, submitted to Clark on June 11, included both FEAF and Task Force 77 units, and Clark approved the lesser plan on June 17, naming Weyland as "coordinating agent". However, in reviewing the plans, the JCS recommended to Truman that the Sui-ho Dam also be attacked and he approved. The JCS authorized the attack on June 19, and the alternate plan was put into effect with a tentative date of June 23 or June 24, which would allow Briscoe to use four aircraft carriers in the operation. The operations plan was finalized when Clark proposed to Weyland that naval aircraft, originally slated only for the eastern complexes, be added to the attack on Sui-ho.
