Developed from Convair F-102 Delta Dagger

The F-106 was gradually withdrawn from USAF service during the 1980s as the arrival of newer air superiority fighters, particularly the McDonnell Douglas F-15 Eagle, had made the role of dedicated interceptors increasingly redundant. Numerous F-106s would be operated for a time by the Air National Guard. Many withdrawn aircraft were promptly converted into target drones and redesignated QF-106 under the Pacer Six program; in this guise, the aircraft continued being used up until 1998. A handful of F-106s were operated by NASA for experimental purposes, such as the Eclipse Project, through to 1998.
On 15 December 1959, Major Joseph W. Rogers set a world speed record of 1,525.96 mph (2,455.79 km/h) in a Delta Dart at 40,500 ft (12,300 m). That year, Charles E. Myers flew the same model aircraft at 1,544 mph (2,484 km/h).
The F-106 was envisaged as a specialized all-weather missile-armed interceptor to shoot down bombers. It was complemented by other Century Series fighters for other roles such as daylight air superiority or fighter-bombing. To support its role, the F-106 was equipped with the Hughes MA-1 integrated fire-control system, which could be linked to the Semi-Automatic Ground Environment (SAGE) network for ground control interception (GCI) missions, allowing the aircraft to be steered by controllers. The MA-1 proved extremely troublesome and was eventually upgraded more than 60 times in service
