From 1937 to 1994, Lowry Air Force Base, located on the eastern edge of the city of Denver, served the nation and the surrounding community in many distinguished ways. The air base, primarily a technical training center, graduated more than 1.1 million enlisted members and officers in skills ranging from armament to photography, tremendously strengthening the country's war efforts in World War II, the Korean War, the Vietnam War, and the Cold War. In addition, from the 1980s, Lowry Air Force Base remained one of Colorado's largest employers, with approximately 10,000 military and civilian men and women, providing an economic impact approaching $1 billion annually. Thus Lowry significantly contributed to maintaining the world's largest air force and to promoting the accelerated growth of the Denver metro area and Colorado.
