I think you are right, I took a look at the document from 2011, as the Sneaky UAV concept, 8-12 metres wingspan and 7-9 metres length are stated. The maximum take-off weight is given as <6000kg. Therefore, the IHA-7 SİNSİ İHA concept must basically refer to the existing Anka-3 prototype model.Please correct me if I am wrong but Sinsi IHA will be a bigger aircraft. I referring subcloud and much smaller UAV, like this demonstrator. It is already in the air, that means a proven concept, why not develop something very useful out of it?

Edit: Also, as reaffirmed in today's ANKA-3 interview of Mehmet Fatih Küçük from Defence Turk, who did a great job as usual, both smaller and much larger scale variants of the current model are also in the planning for future. So I guess we can say that the current aircraft is essentially a technological demonstration and proof of concept. In other words, in addition to the flying wings for more reconnaissance-surveillance and EW purposes in the style you mentioned, we will probably see huge aerial refuelling/penetrator bomber drones with dual 6000 lbs engines in the future.
