The long extended nose appears an armed lethal spike of this retired Canadian CF-5 “Freedom Fighter” jet aircraft sporting a long probe and two 20mm Pontiac M39A2 cannons, exhibited inside Ottawa’s Canada Aviation and Space Museum.
This particular airplane is a Canadair built variant of the original US Northrop F-5 for the Canadian Armed Forces that first acquired them in late 1968 to meet Canada’s commitment in defending NATO’s northern flank during the cold war acting as a rapid-deployment force.
Aircraft such as this one were modified and upgraded constantly during their employ to meet and exceed operating conditions in Canadian Forces theaters of operations approaching a level of sophistication and characteristics similar to the early, more advanced, and capable Northrop F-5 Tiger version.
Although Canada’s CF-5s are no longer flying having been replaced by CF-18s now to be also replaced by perhaps, the Lockheed Martin F-35 lighting II, other countries still fly upgraded versions of the US Northrop F-5, a good example being Switzerland, where it maintains its air superiority function.
