The F-106 Delta Dart is an all weather interceptor aircraft for the United States Air Force.

The F-106 is an advanced derivative of the F-102 Delta Dagger (F-102B). On June 1956, the F-106 featured many designs and modifications and was redesignated as the F-106. In 1957, after some minor redesign of the F-106, a new aircraft designated as the F-106A were delivered to 15 fighter interceptor squadrons. The F-106 served in the continental USA, Alaska and Iceland, as well as brief periods in Germany and South Korea. The F-86 was the second highest sequentially numbered P/F aircraft to enter service under the old number sequence (the F-111 was the highest and its official name, the "Delta Dart" was rarely used and the aircraft was known as "Six". In 1972, some F-106As were upgraded in Project Six Shooter.

The F-106A has a crew of 1. It has a maximum speed of Mach 2.3 and a range of 1,800 mi. The F-106A has one 20 mm M61 Vulcan gatling gun.

In 1981, the F-15A replaced the F-106 and it remained in service in various USAF and ANG units until 1988. In 1986, many of the surviving aircraft were converted into drones and were used for target practice. Only few F-106s were retained by the NASA for test purposes.
