The HESA Azarakhsh (Lightning) is an indigenously manufactured fighter from Iran. The aircraft appears to be based on the Northrop F-5, although larger by 10%-15%. The Azarakhsh is said to use an upgraded version of N-019 Topaz (N-019ME) radar. Several Azarakhsh fighters performed a flyby at the 2008 Military Day in Tehran.
