In December Iran claimed that it had retrieved all data from the U.S. stealth drone RQ-170 Sentinel it had managed to take down a year earlier:
"All the intelligence existing in this drone has been completely decoded and extracted and we know each and every step it has taken (during its missions)," Commander of the Islamic Revolution Guards Corps (IRGC) Aerospace Force Brigadier General Amir Ali Hajizadeh told reporters here in Tehran on Monday.
Today a short video revealed footage the drone had taken on its flights and which the Iranians downloaded from its internal storage. This includes pictures of the Kandahar airbase from which the drone was flown.
Additional footage appears in this Iranian documentary about the drone capture (in Farsi) (24min).
Excerpts (13 min) from that documentary are available with English subtitles:
There is some interesting stuff in it. Iran actually set its missile forces on alarm to let the U.S. know that any attempt to take back the drone or to bomb it would lead to an escalation. It is good that cooler heads prevailed. Other pictures show how the drone was dismantled and transported after it was caught.
Iran had already acquired other U.S. drone types and continues to do so.
Two additional pictures appeared which show Iranian mass production of other U.S. drones it has captured. Visible are copies of the Boeing Insitu ScanEagle and AAI RQ-7 Shadow (marked with those red arrows).
We already know that Iran builds training copies of RQ-170 drones.

But How long will it take those smarting Iranians to build full copies of the RQ-170 stealth drone?
