This CF-100 was manufactured in 1958 as an all-weather interceptor and was one of the last batch produced. Later converted to a Mk.5D electronic counter measures (ECM) aircraft, it was used for simulation of enemy aircraft during NORAD exercises, fitted with wingtip fuel tanks instead of rocket pods to extend range for ECM duties. It served in the electronic warfare role with 414 "Black Knight" Sqdn in North Bay, Ontario until December 1981. It made its last flight on 10th February 1982 and is on loan from the Canada Aviation and Space Museum, Ottawa, painted black to represent the prototype.
