TEHRAN -- Iran has completed the design phase of its stealth aircraft, the commander of the Iranian Air Force announced here on Sunday.

Iranian military researchers are now working on building small prototypes of the aircraft, Brigadier General Hassan Shah-Safi told reporters in Tehran.
The preliminary stages will be finished in late March and then production will begin, he stated.
Iranian engineers have made a major breakthrough in designing stealth aircraft that are difficult to detect by radar.
Shah-Safi said that the Air Force has also tested a new air-to-air heat-seeking missile manufactured by the Iranian military.
The new missile, which has a range of 100 kilometers, will be mass-produced by the Ministry of Defense, he added
