Iran has unveiled a fighter jet which it says is "100-percent" locally made.
Images on state television showed President Hassan Rohani on August 21 sitting in the cockpit of the new Kowsar plane at the National Defense Industry exhibition.
It is a fourth-generation fighter, with "advanced avionics" and multipurpose radar, the Tasnim news agency said, adding that it was "100-percent indigenously made."
State television, which showed the plane waiting on a runway for its first public display flight, said that it had already undergone successful testing.
The plane was first publicly announced on August 18 by Defense Minister Amir Hatami, who gave few details of the project.
The United States has demanded that Tehran curb its defense programs, and is in the process of reimposing crippling sanctions after President Donald Trump withdrew from a landmark nuclear deal between Iran and world powers.
Trump called the 2015 agreement, under which Iran pledged to curb its nuclear activities in exchange for sanctions relief, "the worst deal ever."
