Denver ADS) should be relocated from Ent AFB to Lowry AFB (CO Springs' Chidlaw Building became the new NORAD HQ). In 1960, Lowry was the 3rd ranked technical training base of ATC. ICBM headquarters and training The Air Force Ballistic Committee, formed in 1955, approved the former bombing range on 13 March 1958 for the first Titan I ICBM launch complex (the Titan missile plant was built at Waterton Canyon.) The 703d Strategic Missile Wing was activated on 25 September 1958 and redesignated the 451 SMW on 1 July 1961, at the same time the 848th and the 849 SMS were redesignated the 724th and 725 SMS. Construction on all nine silos at the three launch complexes for the 724 was completed by 4 August 1961. On 18 April 1962, Headquarters SAC declared the 724th SMS operational, and 2 days later the first Titan Is went on alert status. A month later, the sister 725th SMS (initially designated the 849th SMS) declared it had placed all nine of its Titan Is on alert status, which marked a SAC first. Both the 724th and 725th Strategic Missile Squadrons formed components of the Lowry-headquartered 451st Strategic Missile Wing. The "original class of instructors" for the Mace missile course at Lowry graduated from the "G.L. Martin factory training course in Baltimore MD in 1960" and by early 1961, Lowry's personnel course moved to Greenville AFB. By 1962, Lowry's Department of Missile Training was graduating over 1,000 trained missile specialists per year, and the "Tactical Missile School at Lowry" (e.g., for Matador missile training) in January 1962 "was located in the Black Hangar." On 25 June 1965, the 724th and 725th Strategic Missile Squadrons were inactivated, and the last missile supported by Lowry was removed on 14 April 1965. Air Intelligence Training Center The Armed Forces Air Intelligence Training Center was established at Lowry effective 1 July 1963 with student training beginning on 17 July (by 14 March, "the Defense Department had assigned responsibility for all DOD air intelligence training and advanced training in photographic, radar, and infrared interpretation to the Air Force.") In 1965, the runway was closed, and all Lowry AFB flying activities moved to nearby Buckley Air National Guard Base. Ten courses from Amarillo AFB were planned to be moved to Lowry in mid-1968, and Amarillo's 3320th Retraining Group for convicted airmen moved to Lowry 1 July1 September 1967. In 1974,
