Iran has touted its allegedly homegrown ‘Kowsar’ jet fighter, finally unveiled to the public on Tuesday, as a new contender in the arena of air-to-air combat. But the new aircraft was immediately met with wave of criticism from defense industry observers who saw the aircraft as a mere copy of the venerable F-5 which, although a sturdy airframe still in use by the United States military, is considered an antiquated product of the the age of slide rules and hand drawings. After all, boasting about a broadsword in the age of the machine gun is simply an invitation for ridicule.
