It is the future

Everything from WWII is being repurposed with developed sensors and shrunk guidance fitting into 76/127mm shells.
Could be a model placed by the organizers without STM being aware. The details are badly finished and resembles past TF-2000 designs.
It is early for TF-100. But if it happens i would still prefer sketches made by Naval shipyard in the past for 4000+ tonnes instead of this.
Milgem project never ends. TF-2000 is also part of Milgem, the future frigate is, as well.
Every ship is being replaced with a more capable one with higher amount of firepower, same to be expected for Barbaros class. It would be naive to expect same firepower.
Yavuz - to be replaced by I class, 8 to 16 SSM, 16 SS to 64 ESSM.
Gabya to replaced by TF-2000, ? to 16 SSM, 32 SAM +32 ESSM to 48 (32) SAM + 64 ESSM + 0(16) ASuW
Barbaros - ?
Not even including increase in ASW, helicopter operations etc capabilities.
