The F-106 was designed without a gun or provision for carrying bombs, instead carrying its AIM-4 Falcon air-to-air missiles within an internal weapons bay; its clean exterior was beneficial to supersonic flight. Major differences from the F-102 included the adoption of the more powerful Pratt & Whitney J75 turbojet engine, heavily redesigned air inlets along with a variable-geometry inlet duct to suit a wide range of supersonic speeds, and a general increase in size. On 26 December 1956, flown by Richard L Johnson, the first prototype performed its maiden flight. After flight testing demonstrated lesser performance gains than anticipated, the USAF only ordered 350 of the planned 1,000 F-106s.
Becoming operational in June 1959, the F-106 was the primary all-weather...
