Man the project is 30 years old and older than most of the defence enthusiast or let alone, the defence media editors that spreads this sensation. If you carefully look, the older and wiser editors are silent on the matter, as since they know what it is actually about.It is confirmed by Tayfun Özberk that TF-2000 "ADF" is just about the naming scheme of the programme. TF-2000 wont be a "frigate" so calm down.
also we will get to see the final design and news regarding the project soonTM
Frigate or Destroyer, even Navy could have been confused about these terms after all these years and moreover, the image given in the poster could be from an iteration between 2019 - 2022, of when the project was still referred as frigate. Also look at the model and notice 'conceptual' CIWS, missing Nazar and AYR radar and so on, it was not an actual depiction, or not a recent one of the project.
One last remark is that, i strongly believe DzKK considers variations (not batches) of TF-2000, thus the confusion of referring to it as frigate or destroyer emerges.
