At an estimated cost of $25 million, the Convair F-106 was the primary jet used by the United States Air Force during the ’60s, ’70s, and ’80s. It was also the fastest single-engined production aircraft with a top speed of 1,526mph. It was the last of the Interceptor aircraft used by the U.S. Although when they were phased out in the late ’80s many were converted to be used as unmanned drones which lasted through the ’90s.
