school, the Air Corps established the 47th Training Detachment to command the military flight cadets at the school, which apparently also moved to Lakeland along with the school. The school/base closed in December 1945 and was transferred back to the City of Lincoln. Along with its civil use, Lincoln Airport became host to a flying unit of the newly formed Nebraska Air National Guard along with a Naval Reserve unit flying patrol aircraft. The 173rd Fighter Squadron became the host unit of what became known as Lincoln Air National Guard Base. Equipped with P-51 Mustang fighters in 1946, it was the second Air National Guard unit established. A few years later, F-80C Shooting Star jet fighters would replace the unit's F-51s until the advent of the Korean War. The United States Navy Reserve also established Naval Air Station Lincoln (NAS Lincoln) on the airport, primarily as home to Patrol Squadron 762 (VP-762) and its P-2 Neptune aircraft. In 1952 the facility re-opened as Lincoln Air Force Base. After operating as a Strategic Air Command (SAC) base supporting Boeing B-47 Stratojet bombers, Boeing KC-97 Stratofreighter refueling aircraft (by 1954) and SM-65 Atlas intercontinental ballistic missiles (by 1962), the United States Air Force closed the installation in 1966. During the 1960s the two main airlines at Lincoln were United Airlines and the original Frontier Airlines. Frontier Convair 580s flew nonstop and direct to Denver and Kansas City. United Douglas DC-6Bs flew nonstop to Denver, but nonstops to Chicago didn't start until 1967. Lincoln's first jet service began in 1966, with Frontier Boeing 727-100s operating between Denver and Kansas City via Lincoln. United Boeing 727-100s and Boeing 737-200s began flying nonstop to Chicago and Denver about 1968; LNK later saw United 727-200s, 737-300s, 737-500s and Airbus A320s. Frontier later operated 737-200s. Other jet service was operated by America West with Boeing 737-200s and 737-300s nonstop to Phoenix and Trans World Airlines (TWA) DC-9s nonstop to St. Louis. In 1983, Midway Airlines was operating Douglas DC-9-10 jets direct to Chicago Midway Airport via a stop in Omaha. By 1985, three airlines were operating jet service into the airport according to the Official Airline Guide (OAG) including Air Wisconsin with British Aircraft Corporation BAC One-Elevens nonstop from Chicago O'Hare Airport and Grand Island, NE, Frontier with Boeing 737-200s and McDonnell Douglas MD-80s nonstop from Denver and Omaha, and United with Boeing 727-100s and Boeing 737-200s
