The first prototype F-106, an aerodynamic test bed, flew on 26 December 1956 from Edwards Air Force Base, with the second, fitted with a fuller set of equipment, following 26 February 1957.
Initial flight tests at the end of 1956 and beginning of 1957 were disappointing, with performance less than anticipated, while the engine and avionics proved unreliable.
These problems, and the delays associated with them nearly led to the abandoning of the program, but the Air Force decided to order 350 F-106s instead of the planned 1,000.

After some minor redesign, the new aircraft, designated F-106A were delivered to 15 fighter interceptor squadrons along with the F-106B two-seat combat-capable trainer variant, starting in October 1959.

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).

The F-106 was envisaged as 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.
Similar to the F-102, it was designed without a gun, or provision for carrying bombs, but it carried its missiles in an internal weapons bay for clean supersonic flight.
It was armed with four Hughes AIM-4 Falcon air-to-air missiles, along with a single GAR-11/AIM-26A Falcon nuclear-tipped semi-active radar (SAR)-homing missile (which detected reflected radar signals), or a 1.5 kiloton-warhead AIR-2 (MB-2) Genie air-to-air rocket intended to be fired into enemy bomber formations.

Like its predecessor the F-102 Delta Dagger, it could carry a drop tank under each wing.
Later fighters such as the Phantom and F-15 Eagle carried missiles recessed in the fuselage or externally, but stealth fighters would re-adopt the idea of carrying missiles or bombs internally for reduced radar signature.

Operational history
The F-106 served in the continental USA, Alaska, and Iceland, as well as brief periods in Germany and South Korea.
The F-106 was the second highest sequentially numbered P/F- aircraft to enter service under the old number sequence (the F-111 was highest), before the system was reset under the 1962 United States Tri-Service aircraft designation system. In service, the F-106's official name, "Delta Dart," was rarely used, and the aircraft was universally known simply as the "Six."

Although contemplated for use in Vietnam the F-106 never saw combat nor was it exported to foreign users.
Following the resolution of initial teething problems (in particular, an ejection seat that killed the first 12 pilots to eject from the aircraft) its exceptional performance made it very popular with its pilots.

In an effort to standardize aircraft types, the USAF was directed to conduct Operation Highspeed, a fly-off competition between the USAF F-106A and the U.S. Navy F4H-1 (F-4B) Phantom, which was not only as capable as the F-106 as a missile-armed interceptor, but could also carry as large a bomb load as the F-105 fighter bomber.

The Phantom was the winner, but would first be tasked to escort and later replace the F-105 fighter-bomber in the late 1960s before replacing older interceptors in Air Defense Command in the 1970s.

The F-106 was progressively updated in service, with improved avionics, a modified wing featuring a noticeable conical camber, an infrared search and track system, streamlined supersonic wing tanks which provided virtually no degradation to overall aircraft performance, better instrumentation, and features like an inflight refuelling receptacle and an arresting hook for landing emergencies.

Air-to-air combat testing suggested the "Six" was a reasonable match for the F-4 Phantom II in a dogfight, with superior high-altitude turn performance and overall maneuverability (aided by the aircraft's lower wing loading).
But the Phantom had better radar, an additional crewman to operate the radar, and could carry a load of up to four radar-guided Sparrow and four infrared Sidewinder missiles, while Falcon missiles proved a disappointment for dogfighting over Vietnam.

An U.S. Air Force Convair F-106A Delta Dart (s/n 57-2494) of the 102nd Fighter Interceptor Wing of the Massachusetts Air National Guard based at Otis Air Force Base, Massachusetts (USA), intercepting a Soviet Tu-95 Bear D bomber aircraft off Cape Cod on 15 April 1982. The F-106A 57-2494 (c/n 8-24-77) was retired to the AMARC as FN0163 on 29 December 1987. It was converted to an unmanned QF-106A drone and shot down with a FIM-92 Stinger hand-held surface-to-air missile on 27 August 1996.
