On & August 1952, CJTF SEVEN submitted a report to the Joint Chiefs of Staff outlining the military participation program for CASTLE, then planned as a 4-shot nuclear and thermonuclear test operation scheduled for September - October, 1953. On 20 October 1952, the Joint Chiefs of Staff made certain modifications to this report and approved the program for planning purposes only. Concurrently, the Joint Chiefs of Staff directed the joint task force commander to revise the military force requirements on an austere basis. Subsequently, the AEC and the Department of Defense (DOD) approved a plan to broaden CASTLE to a 6-shot (all thermonuclear) operation and to postpone the tests until January - February of 1954. The program was later increased to seven shots. The Commander, JTF SEVEN, submitted modified support requirements, as directed, on 17 February 1953, having withheld action until the AEC could formally present a proposed revision of the CASTLE concept. On 1, April 1953, the Joint Chiefs of Staff approved the modified support requirements and authorized CJTF SEVEN to further modify the military requirements as changes were made in the operational concept of the tests. The commander of the joint task force was further authorized direct communications with the three military Services to effect further modifications, The Joint Chiefs of Staff instructed each military Service to establish suitable priorities to insure timely manning and equipping of the task force and to provide additional forces and services as necessary.
