The F-106 Delta Dart is a supersonic, all-weather interceptor. Originally envisioned as an advanced derivative of the F-102A Delta Dagger and given the designation F-102B, the "Ultimate Interceptor", as it was known, entailed such extensive changes that in June, 1956, the designation was changed to F-106.  It was designed from the ground up as an Interceptor and nothing but an interceptor.  Originally designated the F-102B, it was re-designated the F-106 due to it's extensive structural changes and the more powerful Pratt & Whitney J57 engine.   The single seat F-106A first flew on December 26, 1956, was delivered to and entered operational service with the US Air Force (USAF) in May 1959 and achieved initial operational capability in October, 1959.  The two-seat F-106B made its maiden flight on April 9, 1958, achieved initial operational capability in July 1960, and retained the full combat capability of the F-106A.  All F-106 production ended in late 1960 with a total of 277 F-106A's and 63 F-106B's being built at a cost of about $5 million each.

The Delta Dart was manufactured by the Convair Division of General Dynamics. It's design, and that of its predecessor the F-102A, is closely linked to Langley and the development of "area ruling" in the early 1950's. Area Ruling, which reduces drag at transonic speeds, is reflected in the "coke bottle" or "wasp waist" shaped fuselage of the F-106. Area ruling enabled the YF-102A to easily exceed the speed of sound and subsequently led to the go-ahead for the advanced version which became the F-106. The significance of area ruling was recognized by the National Aeronautic Association which awarded the originator, Richard T. Whitcomb, its prestigious Collier Trophy for the greatest achievement in aeronautics in 1955.

The F-106 was powered by a single Pratt and Whitney J75-P-17 turbojet engine of 16,100 LB thrust (24,500 LB thrust with afterburning). Developed as an interceptor, its mission was to shoot down other aircraft, bombers in particular. It used a Hughes MA-1 electronic guidance and fire control system, which after takeoff would be given control of the aircraft to fly it to the proper altitude and attack position. Then it can fire the Genie Air 2A Nuclear Rocket and Hughes Aim 4 Falcon missiles, break off its attack run, and return the aircraft to the vicinity of its base. The pilot takes control again for the landing.

The F-106 also came in a 2 seat "B". Unlike other popular 2 seat aircraft, such as the F-4, the back seater in the "SIX" had the exact same control capability as the front seater. He could fly the aircraft and perform all operations from his rear seat. The F-106B also could carry the same armament.

On December 15, 1959, Colonel Joe Rogers piloted an F-106A to a World Speed Record of 1,525.695 mph (Mach 2.41). The F-106 still holds the record as the fastest single-engine turbojet-powered airplane.

The F-106 served with the USAF Air Defense Command (ADC), Tactical Air Command (TAC), and Air National Guard (ANG). The Air Force retired the F-106 from active squadron service after a long and distinguished career. The post Delta Dart period saw them used as drone targets during air-to-air missile training for our current generation of fighter aircraft, the Eclipse Tow Project, and many are on Static Display in aircraft museums throughout the Unites States.

F-106 Pilot and who "Fired simulated AIR2A in William Tell Competition without Operational MA-1!"

"I put in 24 years in the AF, 23 flying, 3300 hours flying the F-106 and numerous assignments at NORAD/ADC/ADTAC dealing with the F-106 and its employment. The descriptive words in the article on the F-106 sounds like it was written by Hughes Aircraft in selling the airplane....The MA-1 NEVER had full control of the aircraft, which capability so many publications erroneously extol. The MA-1, using its data link target information or command information, would provide directives for altitude, airspeed, xyz coordinates and command directions, which would be flown by the autopilot, however, the MA-1 NEVER regulated the throttle at any time, for forward and aft movement, thus the MA-1 could never really fully control the airplane except to provide requested directions that required coupling and thrust selection by the pilot. The pilot HAD to take it off, climb, descend, and land the aircraft, every time!...

The challenge was to get the landings to equal the number of takeoffs!

The F-106 proved its ultimate performance capabilities in providing aggressor "enemy" delta-wing familiarization training to the Navy's best pilots during the time they were implementing TOP GUN. The Navy jocks learned valuable lessons that the Delta winged 106 was almost unconquerable in the dogfight arena, with guns in the air-to-air environment, which you read so little about in the Navy publications. Wing loading of 43 lbs/sq ft and a .8 -1 TWT put it in a class of its own against the A4s, F-104s, F4B,C,D, F-105, F-100, F8 fighters of its time.....not to mention the many many '14s and '15s that blew engines in attempting to fight when it took them above 40,000 feet, to a guns-only environment.
Good thing they finally fixed those great fighters to handle the altitudes the 106s formerly ruled.

The F-106 uses a Hughes MA-1 electronic guidance and fire control system. After takeoff, the MA-1 can be given control of the aircraft to fly it to the proper altitude and attack position. Then it can fire Fires the Genie and Falcon missiles, break off the attack run, and return the aircraft to the vicinity of its base. The pilot takes control again for the landing.

The aircraft on display at The Air Force Museum (S/N 58-0787) was involved in an unusual incident. (During a training mission from Malmstrom AFB on February 2, 1970, it suddenly (NOT ALL THAT SUDDEN!) entered an uncontrollable flat spin forcing the pilot to eject. Unpiloted, the aircraft recovered on its own, apparently due to the balance and configuration changes ), caused by the ejection, and miraculously ( made a gentle belly landing in a snow-covered field near Big Sandy, Montana . After minor repairs, the aircraft was returned to service. It last served with the 49th Fighter Interceptor Squadron before being brought ( to the Museum in August 1986.

Just my contribution to add color to the "history of airplanes without pilots."
