In January 1947, the rest of Z Division completed its move to Sandia Base. That same month, Secretary of War Robert P. Patterson and Secretary of the Navy James V. Forrestal established the Armed Forces Special Weapons Project (AFSWP) to assume all of the military functions of the Manhattan Engineering District. The ASWP took over the Albuquerque base. Z Division and AFSWP brought to Sandia Base the strict secrecy which had prevailed at Los Alamos. In 1947, amid much public speculation about what was going on at Sandia Base, the military would only say that the activities at Sandia Base were secret under the Atomic Energy Act. When Secretary of the Army Kenneth Claiborne Royall visited Sandia Base in 1948, he falsely announced that "guided missile" development was underway at the base.
