@Terminator in another forum has a better theory though on F110 engine with drone:
Could it be that ANKA-4 needs an engine?
Then a UCAV with a higher MTOW than the HÜRJET and a lower MTOW than the KAAN is coming. If it is a twin F110, TAI is directly making a kind of KAAN without cockpit or they are preparing a huuuge strategic platform... But this would really be a fantasy speculation, because if a strategic bomber drone of that size was being developed, there would be news about a non-afterburner engine with higher fuel economy instead of the F110. When I think with the F110, I just no other guess than an agile, supersonic fighter jet.
edit:
I looked at the related news, and I saw that he said during TEKNOFEST in August: "We are continuing with ANKA-3. There will also be ANKA-4. We are in talks with some countries. Our aim is to find partners for these.' I think we had evaluated this on the back pages, so we remembered it again.
Other than that, there are not many details, but it makes us think that ANKA-3 and ANKA-4 are going to follow one right after the other without any gap, and perhaps ANKA-3 is to some extent the technological preparation for ANKA-4. On the other hand, the statement that we are in talks with some countries and trying to find partners for them is also important. If one of the current aviation projects should be kept in a more restricted area in terms of not being opened to external partners as a high strategic asset under all circumstances, my opinion here is that that platform should definitely be ANKA-4.
