Pictures on the internet appear to show Iran's secret "Saegheh" fighter-bomber flying in formation with a Northrop F-5E Tiger, on which it is modelled, on a test bombing mission. Iranian state media say the military has carried out a successful test flight of "Saequeh", a reverse-engineered F-5 with a revised butterfly tail configuration in place of the original vertical tail surface.
