as well as the LGM-25C Titan II and LGM-30 Minuteman ICBMs, and the LIM-49 Spartan ABM. On 1 July 1971, Kirtland merged with Sandia Base and Manzano Base, its neighbors to the east. Twelve months after the merger, Kirtland AFB became home to one of the country's most important industrial management units when the Air Force Contract Management Division (a component of Air Force Systems Command) moved to the base from Los Angeles. Early in 1974, at the direction of the Air Force Chief of Staff, the Air Force Operational Test and Evaluation Center was organized at Kirtland to direct and oversee operational testing of aircraft and other equipment. Laser technology Laser R&D became a mission for AFWL during the 1960s and was its main focus into the 1970s. The military began to view lasers as potentially superior to conventional weapons because of lasers’ intensity over great distances and envisioned developing them for ballistic missile defense, as well as anti-satellite and anti-aircraft missions. In 1968, the USAF authorized the AFWL to design, build, and fire a GDL capable of engaging targets that were static or in motion. The Advanced Radiation Technology Office at AFWL built its TSL at SOR in 1971, naming it the Air Force Laser (AFL). Mating of the AFL and Field Test Telescope (FTT)—the first step toward shooting down an aerial target with a laser—took place in October 1972. The successful mating of the AFL and FTT in 1972 was a milestone in the USAF high-energy laser research. That same year, AFSC assigned responsibility for the USAF's portion of the DoD's high-energy laser program to AFWL. AFWL scientists were determined to use the AFL to shoot down a drone aircraft. A year later, in November 1973, the AFWL met the three milestones and succeeded in the first shoot down of an aerial target by a laser. While a ground laser could track and engage a moving target, an airborne laser had the added difficulties of vibrations, beam propagation, and pointing a laser from an aerial platform. Development of the Airborne Laser Laboratory (ALL) became the centerpiece of AFWL's laser program in the 1970s. The ALL term was coined in 1972, and the ALL program began with Cycle I testing in 1973 and ended with the completion of Cycle III in September 1983. The ALL was a modified NKC-135, and the 4900th Flight Test Group was formed for
