Iran will manufacture four versions of the US RQ-170 drone which was downed inside the country in December 2011, a top military commander said .

Iran plans to produce four duplicated versions of RQ-170 by the end of the current Iranian calendar year (which ends March 20, 2015), Commander of the Aerospace Division of the Islamic Revolution Guards Corps (IRGC), Xinhua quoted Brigadier General Amir-Ali Hajizadeh as saying.

Unlike the original American version which is a spy drone, the first Iranian models are combat drones, he added.

It was announced Monday that Iran had put into operation a version of the US RQ-170 drone and it had made a successful inaugural flight.

A footage of the RQ-170’s flight test was also released by state TV Wednesday.

Earlier this year, Iran aired “decoded video recordings” which it said were obtained from a U.S. RQ-170 stealth aircraft. The recordings had been made by the drone’s underbelly camera and included views from the area surrounding the Kandahar base in Afghanistan as the drone was about to land.

In December 2011, Iranian media reported that the Iranian military downed the U.S. RQ-170 in the eastern part of Iran after finding it transgressing the eastern border.
