The pic for which this thread was first created isnt the Saeqeh..other pics of it exist and shows its a Single Engine fighter not a twin engine design like the Saeqeh. It's not a very modern modern design but an interesting one. This model has been seen for many years now, mostly really closeup and fuzzy pics and I think they publish them just to throw people off. No one really knows what it is, likely an Iranian concept from the 90's.
The previous image posted has also been on the net for many years (along with a supposedly picture of it flying but looks very PS), its an interesting concept but unknown if it even is an Iranian design at all or a hobbyist having fun with us, but it has been around for sometime so who knows..
