Iranian experts overhauled an F-27 military plane at an airbase in Tehran province.
Iran's Air Force experts and engineers overhauled the warplane after 25,000 man-hours of labor at martyr Lashkari base in Tehran, Fars News Agency (FNA) reported.
The warplane joined the Air Force on Saturday morning after training flights and passing the final tests.
In recent years, Iran has made great achievements in the defense sector and gained self-sufficiency in manufacturing essential military hardware and defense systems.
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.
In a relevant development in 2016, the Iranian Air Force announced that its experts at Shahid Lashkari airbase had managed to overhaul an F-4 fighter jet.
The overhauling operations of the fighter jet took 18,000 man/hours of work. The F-4 aircraft joined the Air Force fleet after making its maiden flight in Tehran.
The aircraft is back to service after it was grounded for four years.
