"Military Experts are working on the radar-evading aircraft and God willing its test flight will be done in the first half of the next (Iranian) year (beginning on March 20)," Shahsafi told reporters here in Tehran.
He added that the experts have already designed and manufactured the aircraft in a one-seventh scale.
"After test flights and equipment testing, the project will be transferred to the defense ministry for the start of mass production," the Iranian air force general reiterated.
Stressing that defensive measures set a priority for the air force, he added, "All actions and achievements of the Iranian army solely serve defensive purposes."
The commander also reiterated the craftsmanship of Iranian experts, and said that they enjoy the most advanced technologies in producing military tools and equipment.
Referring to the test-firing of a heat-tracing air-to-air missile, Shahsafi announced, "The test was successfully done in two phases and we are increasing our missiles' range in line with our defensive doctrine," he said.
The military official said that the missile which has a range of 40 kilometers has been successfully fired in two separate tests in Tabriz and near Tehran, "and now we are increasing its range."
Tehran launched an arms development program during the 1980-88 Iraqi imposed war on Iran, to compensate for a US weapons embargo. Since 1992, Iran has produced its own tanks, armored personnel carriers, missiles and fighter planes.
Yet, Iranian officials have always stressed that the country's military and arms programs serve defensive purposes and should not be perceived as a threat to any other country.
