After the war, Radford was a principal opponent to a plan to merge the uniformed services. A plan existed to split the Army and the Army Air Forces into separate branches and unite them and the Navy under one Cabinet-level defense organization. Fearing the loss of their branch's influence, Navy commanders opposed the formation of a separate Air Force and favored a more loose defense organization. Radford was picked by Forrestal to form the Secretary's Committee of Research and Reorganization. Months of discussion resulted in the National Security Act of 1947, a political victory for the Navy because it created the U.S. Air Force while resulting in a coordinated, not unified, U.S. Department of Defense with limited power and with the Navy maintaining control of its air assets. In 1947, Radford was briefly appointed commander of the Second Task Fleet, a move he felt was to distance him from the budget negotiations in Washington, but nonetheless preferred.
